Hello. We’re Teya. Teya was founded on a simple belief: local businesses deserve better. They are the cafés, restaurants, salons, shops and entrepreneurs that bring character to our high streets, create jobs and keep communities moving. Yet for too long, financial services has made life harder for them - with clunky tools, poor support and complexity that gets in the way of running a business. Teya exists to change that. We’re building a financial platform for local businesses across Europe - one built around simple tools, thoughtful design and real human support. Our Members rely on us to help them run their business with confidence, and that responsibility shapes the way we work. We move fast. We care about quality. We stay close to the detail. And we believe great performance and genuine hospitality should go hand in hand. If you want to build meaningful products, solve real problems and make a genuine difference for local businesses, we’d love to hear from you Teya is building out its Commercial Planning & Performance team, which will be the analytical backbone of our commercial organisation. We're looking for a Commercial Planning Manager to own the central planning machine across our long-range plan, annual budget, and quarterly target-setting. This is the seat that holds the planning system together for the Commercial organisation, running the planning process, structures the decisions, and turns ambition into plans the business can deliver against. You'll coordinate inputs across Finance, Product, Engineering, Data and our country teams, translating strategic direction into clear targets, budgets and operating outputs, and holding the cadence that makes it work. This is a high-ownership, high-visibility individual-contributor role for someone who is energised by ambiguity, builds order quickly, and is as comfortable in front of leadership as they are in a spreadsheet. What you'll do * Own the five-year plan end to end: calendar, inputs, topline and cost assumptions, scenario logic, country and channel outputs, and the materials that drive leadership decisions. * Own the annual budget from kickoff to sign-off: governance, assumptions, review cycles, and alignment between topline targets, cost plans and strategic priorities, in close partnership with FP&A. * Run the quarterly target-setting process: translating the annual plan into targets across countries and channels, calibrating with country leaders and channel owners so targets are realistic, economically grounded and operationally deliverable. * Hold the planning rhythm together: define the cadence, templates, decision points and ownership; track dependencies; surface trade-offs early; improve planning quality, transparency and speed over time. * Turn ambiguity into structured answers: frame open business questions as planning problems, run the scenario and sensitivity work behind decisions, and produce executive-ready materials that are clear about the recommendation, not just the analysis. What we're looking for * 3–6 years in strategy consulting, investment banking, strategic finance, business operations at a high-performing company. * Exceptional structured problem-solving; you can take an ambiguous question, frame it, and break it down into something the business can act on. * Strong analytical and modelling skills. Advanced spreadsheet fluency essential; comfort interrogating financial models and planning logic. * Process and project management instinct; you build operating rhythms naturally and follow through relentlessly across teams you don't own. * Excellent written and verbal communication; credible with executives, country leaders and senior cross-functional stakeholders. * High ownership and calm under pressure; able to hold a complex system together without losing the thread. A plus * Experience in fintech, payments, SaaS or another multi-country commercial environment. * Exposure to sales planning, target-setting, channel planning, or commission/pricing-related work. * Hands-on experience with planning, budgeting or performance operating cadences. THE PERKS * Physical and mental health support through our partnership with GymPass giving free access to over 1,500 gyms in the UK, 1-1 therapy, meditation sessions, digital fitness and nutrition apps. * Cycle-to-Work Scheme. * Health and Life Insurance. * Pension Scheme. * 25 days of Annual Leave (+ Bank Holidays). * Possibility to travel to different offices around Europe. * Office snacks every day. * Friendly, comfortable and informal office environment in Central London. * Flexible working hours, as long it suits both you and your team. Teya is proud to be an equal opportunity employer. We are committed to creating an inclusive environment where everyone regardless of race, ethnicity, gender identity or expression, sexual orientation, age, disability, religion, or background can thrive and do their best work. We believe that a diverse team leads to better ideas, stronger outcomes, and a more supportive workplace for all. If you require any reasonable adjustments at any stage of the recruitment process whether for interviews, assessments, or other parts of the application—we encourage you to let us know. We are committed to ensuring that every candidate has a fair and accessible experience with us.
SENIOR PRODUCT ENGINEER - INSIGHTS LET'S FIX HOSPITALITY, FOR GOOD. Hospitality runs on thin margins, and most operators are stretched trying to protect them. We built Nory. Our CEO, Conor, knows the pain first-hand. He founded and scaled Mad Egg in Ireland and grew tired of stitching together so-called market-leading systems and spreadsheets just to keep the business running. He set out to build the tool he wished he'd had from day one. Nory is a restaurant management system that blends real-time data with AI predictive analytics to give operators real control of their margins. From food prep to forecasting, it is the operational intelligence that helps restaurants run profitably, with less waste and better jobs for the people working in them. Fresh off a Series B led by Kinnevik, we've grown to over 100 people across Ireland, the UK, Spain and New York. Demand is scaling faster than we expected. The role We're looking for a Senior Product Engineer to join our Insights Squad. This is a full-stack, product-focused role on the squad that builds Nory's scheduling and forecasting. You'll work across the full stack, with backend as your foundation, which is where the hardest problems on this team live. As a product engineer, you'll help shape what gets built, working alongside our product and design functions. You'll speak to customers directly, make trade-off decisions without perfect information, and define and ship MVPs that you then improve on real feedback. The squad and the moment: The Insights squad is, in practice, our applied data science team. We own the whole journey, from the data pipeline through to the customer-facing product that operators rely on every day. Right now we are taking our scheduling assistant to general availability and building out our forecasting engine, predicting sales and orders across one-day, one-week and two-week horizons and making those predictions reliable in every restaurant setting. These are genuinely hard computer science problems, and we solve them inside a real, evolving system where we balance shipping quickly against the refactoring that keeps us fast. A lot of the work sits in the space between software engineering and machine learning, in close partnership with our data scientists. We're stack-agnostic in hiring and care most about strong fundamentals and the ability to ramp quickly. Our current stack is Python, FastAPI, React, TypeScript, Node.js, AWS (Fargate, Aurora, SQS), Postgres, MongoDB, and Docker. WHAT YOU'LL BE DOING Our squads are cross-functional and run with a lot of autonomy. You'll own problems end to end, from discovery through to production and iteration, working closely with product, design, data and customer success in a tight feedback loop with real customers. Key projects you'll be working on: * Build the systems that turn raw restaurant data into real-time insight, helping operators spot opportunities and protect their margins. * Develop embedded analytics that surface the right insight at the right moment inside the product, so operators can act on it without leaving Nory. * Ship enhancements to our forecasting engine, making predictions more accurate and easier to trust, so operators rely on them to plan. * Extend the Insights platform with new capabilities across cost management and business performance, including the move towards dynamic pricing. * Help build a self-serve analytics layer that lets operators explore their own data and understand how the business is performing without needing external tools. * Work on our customer feedback module, where sentiment analysis and automation help brands stay on top of their online presence. * Work closely with peers in Product, Design and Engineering to ship quickly and keep our technical standards high as we scale. WHAT YOU'LL BRING * Backend depth is the primary bar. You've built and owned production backend systems that real customers depend on, including APIs, data models and distributed services. You can talk through specific data modelling decisions you made yourself, the constraints you were working within and why you made the calls you did. You design for the ways a system fails, not only for the path where everything goes right. * You're comfortable across the full stack. You've shipped front-end work in React and TypeScript alongside your backend work, and you move between the two depending on what the problem needs. This squad works closer to an even split between front-end and backend than most, and we want someone who can own work on both sides. * You own problems, not tickets. You can point to things you personally shaped, where you pushed back when a requirement was vague or proposed a different route when the original plan was wrong, and you took responsibility for how it turned out. When you describe your work, you tend to say "I decided" rather than "we decided." * You've built in constrained environments. Whether that was a startup, a high-stakes project inside a larger company or a greenfield build on a tight deadline, you've worked through real ambiguity and shipped something that mattered. You know what an MVP actually is, because you've shipped one. * You engage with customers directly. You've spoken to users, let what you heard change what you built, and can give a specific example of when it did. You treat customer feedback as part of the engineering job and stay close to it. * You're pragmatic under pressure. You've deliberately shipped something rough to get feedback quickly, and you know when a problem needs the right solution and when it needs the fastest one that proves the point. BONUS POINTS * Experience building B2B products at scale, with high volumes of users, traffic or data. * Experience with analytics-driven products, where accuracy and reliability decide whether customers trust what they see. * Professional experience with Python, which is a real plus on this squad. * A background in forecasting, scheduling, optimisation or other applied data science work, or comfort building alongside machine learning models in production. * Experience in hospitality, food service or another operational industry where software has to hold up in the real world. * A track record of staying with a company as it grew and taking on harder problems over time, rather than moving on quickly. OUR STACK Python, FastAPI, React, TypeScript, Node.js, AWS (Fargate, Aurora, SQS), Postgres, MongoDB, Docker WHAT YOU'LL GET IN RETURN * Remote-first working environment * Competitive salary depending on experience * Meaningful equity. At Nory, everyone is an owner * 35 days of paid leave per year (including bank holidays) * Comprehensive private health insurance via Irish Life (Ireland) and AXA (UK) * Enhanced parental leave and baby loss support * Learning and development culture, with a €1,000 personal annual budget plus a quarterly book budget * €250 home office workspace budget * Regular team offsites and socials * Work from anywhere for up to 3 months of the year * Offices in London, Dublin, or Spain HOW WE WORK Our vision is to build a better future for the restaurant industry, one where operators are in control of their businesses and the people on the floor can build careers they are proud of. To get there we move fast, stay focused and hold ourselves to a high bar. Our values guide how we work and grow together. * We serve up impact with a side of profit. We prioritise work that delivers real financial results for our restaurant partners * We prioritise speed of service. We move fast, unblock each other and deliver with urgency * We act like owners. We take problems on, raise the bar and build better every day * We win as a crew. We grow stronger through feedback, collaboration and shared wins WE HIRE HUMANS. At Nory, we believe that diverse teams build better products. We welcome applicants from all backgrounds, identities, and walks of life. We do not discriminate based on gender, ethnicity, sexual orientation, religion, family status, age, disability, or race. What matters to us is how you think, how you work, and what you bring to the table.
What will you do? As a AI/ML Engineer at Rebtel you will define how AI is done at Rebtel. What tooling we standardise on, how we evaluate models we put in front of real users, what "good" looks like for our prompts and our pipelines. AI is going from a side project to the core of how Rebtel operates and what we ship to our users. We're hiring the second engineer on our ML/AI subteam to help build it classical ML for the business, LLM-powered systems for the product, and a clear production mindset on both. You'll sit inside the Data team, report to our Head of Data, and partner with one other ML/AI engineer to shape this capability from the ground up. Areas of ownership: You'll own work across two complementary tracks, and you'll ship in both. Classical ML, in production, for operational leverage Risk and fraud models across payments, top-ups, and account behaviour Churn prediction and retention modelling on a user base of a million-plus Forecasting, pricing, segmentation, and the next batch of operational problems we haven't tackled yet Owning models end-to-end scoping with stakeholders, building, deploying, monitoring, retraining LLMs and AI agents, from internal automation to in-product features Start with our customer support agents and automations: RAG pipelines, prompt orchestration, tool-use, evaluation harnesses Move LLM capability into the product as user-facing features Help guide the company on where AI actually creates leverage, what to build, what to buy, what to ignore and turn the good ideas into shipped systems Requirements: You are an excellent communicator and collaborator. We work in English, but you will hear many languages in our Stockholm office 4+ years of hands-on ML engineering in Python, with real production ownership not just notebooks Strong fundamentals in classical ML: feature engineering, model selection, validation, and the unglamorous parts of keeping a model healthy in prod A genuine production mindset: monitoring, retraining, eval harnesses, CI/CD for models, and the instinct to debug when something drifts at 2am Comfort working the whole loop: stakeholder scoping → data → model → deployment → measurement → iteration Strong written and spoken English, and the ability to translate between business problems and ML ones Hands-on experience with LLM frameworks — LangChain, LangGraph, LlamaIndex, or equivalents Built RAG systems, agentic workflows, or LLM-backed products that real users (or real internal teams) actually used Comfortable with vector databases, embeddings, prompt evaluation, and measuring LLM systems with something more rigorous than vibes Obsession with staying up-to-date on developments in the AI space Experience with a major cloud (AWS / GCP / Azure), containers, and a modern data stack Experience in MLOps tooling: MLflow, Airflow, Kubernetes and feature stores is a plus Background in fintech, payments, telecom, or other regulated / operational domains is a plus Why Rebtel?
