ABOUT THE ROLE We're looking for a Senior Product Engineer – a product person with real technical depth and an AI-first mindset. Your primary focus is product: identifying problems worth solving, shaping solutions, and driving them from 0 to 1. You understand architecture, you've written code, you know how databases work, and you speak engineering fluently. AI is not a feature we're adding – it's how we work and how we build. Think 70% product, 30% engineer, 100% accountable for results. YOUR MISSION * Own 0-to-1 development of new products and features – from problem discovery to launch to iteration. * Define what to build, why, and how to measure success – then see it through. * Work directly with users, support, and data to understand real problems, not assumed ones. * Run experiments, define metrics, and shut down what doesn't work. * Collaborate deeply with engineering – understand architectural trade-offs, review technical approaches, and unblock decisions. * Prototype and validate ideas fast using AI tools (Claude, Cursor, Copilot, agents), scripts, no-code, or whatever gets you to the answer quickest. * Identify where AI and LLMs can create real product value – and build the case for it. * Write product specs and briefs that engineers actually want to read – clear, technical, and opinionated. * Stay hands-on: write queries, dig into data pipelines, spin up prototypes, open a PR when it makes sense. YOUR PROFILE * Degree in Computer Science, Software Engineering, or a related technical field. * 5+ years in product management, product engineering, or a similar role with strong technical involvement. * You know at least one programming language well enough to build things yourself (Python or similar). * Comfortable with git, databases, and evaluating system architecture. * Proven track record of taking ideas from 0 to live product with real users. * AI-native way of working – you use LLMs, vibe coding, and AI agents daily to move faster and validate ideas. This isn't optional, it's core to how we expect you to operate. * Strong analytical skills – comfortable with data, metrics, and decisions under uncertainty. * Clear communicator in English – you can explain technical decisions to non-technical stakeholders and write specs engineers respect. * Self-directed – you don't wait for someone to tell you what matters. Nice to have: * Experience in fintech or regulated industries. * Early-stage startup background. * Hands-on LLM orchestration or prompt engineering. * Product analytics, Software engineer, or QA background. WHY JOIN VIVID? * We have a hybrid model in our Limassol and Berlin offices, or fully remote outside office locations. * We support relocation to Cyprus (visa, package) when needed. * Competitive senior-level compensation, reflecting the seniority and impact of the role (depending on location). * AI-first culture – we use it every day, not just talk about it. * Learning & development budget to support your professional growth. * Fully paid vacation and sick leave. * Sports compensation. * Real growth prospects, significant responsibility, and the ability to make an immediate impact from day one. Enhance your expertise and shape the future of FinTech. Join Vivid's talented team and help us revolutionize how businesses think about their finances! COMPENSATION RANGE Final compensation is determined individually, based on your experience, skills and the scope of the role, assessed against objective, gender-neutral criteria. ABOUT VIVID At Vivid, we're on a mission to change how businesses and individuals manage their money across Europe. For businesses, we build tools that actually make a difference: multi-IBAN accounts, high-yield savings, business cashback, team cards, and accounting integrations that save real time – all in one place. And for individuals, everything you need to grow your wealth: investments in global stocks, ETFs and 150+ cryptocurrencies, cashback, and personalised financial insights. Our mission? Your success. Everyone deserves the chance to see their finances flourish, and we're dedicated to empowering our customers to make this a reality. Founded in 2019 in Berlin by Alexander Emeshev and Artem Iamanov, Vivid has quickly grown into one of Germany's top financial platforms for SMEs and private accounts. Since then, we've expanded rapidly across Europe, earning the trust of over 500,000 customers – and with over €200 million raised and a valuation of €775 million, we're just getting started. We're building Vivid as an AI-native organization – across every function, from product to compliance to operations. For us, this means agents handle the execution while our people focus on architecture, strategy, and decision-making. We want to help define what AI-native looks like in a regulated financial environment – and we're looking for people who want to build that future with us.
OUR MISSION Bounti is building the AI-native infrastructure layer for frontline teams — spanning training, audits, and autonomous operations. We partner with multi-location operators in frontline-industries such as hospitality. We’re hiring a Senior Product Engineer to join our founding product team in Berlin. This is a hands-on role for someone who loves ownership, sweats UX details, and ships fast, end to end delivering value for customers. WHAT YOU'LL DO * Build Product End-to-End: Own features from concept → implementation → release → iteration (frontend + backend). * Ship Fast, Learn Faster: Deliver quickly, validate with customers, and iterate. Biggest risk is building the wrong thing — not imperfect code. * Customer-Driven Engineering: Talk to users and customers directly, understand the workflow pain, and turn feedback into product improvements. * Design-First Execution: Partner closely with Ziar (Designer & Co-Founder) to create experiences that feel premium and intuitive. * Raise the Engineering Bar: Improve patterns, code quality, DX, testing, and observability without slowing down shipping. * Work Like a Founder: Prioritize ruthlessly, own outcomes, and help shape what “great product engineering” looks like at Bounti. YOUR PROFILE * You have a strong product sense — you care about UX, clarity, and the tiny details that make software feel “right”. * You’re strong on the backend (you’ve built and scaled real production systems) — and you’re not afraid to go deep when needed. * You’re pragmatic and impact-driven: you know when to polish and when to ship to learn. * You write clean, understandable, maintainable code — and you communicate context early and often. * You enjoy getting close to the problem: talking to customers, understanding real-world constraints, building solutions that stick. * Experience with our stack is a plus: TypeScript, React, Next.js, Node.js, Postgres, Prisma. Bonus points if you have: * Built AI product features (LLMs, agents, workflows, evaluation, etc.) * Mobile product experience (Flutter, React Native or similar) * ML experience You’ll work extremely closely with: * Çağatay (Senior Product Engineer) * Emanuele (Senior Product Engineer) * Yannick (Software Engineer) * Ziar (Designer & Co-Founder) …and often with Deniz (Co-Founder) who brings constant customer perspective. This is a small, high-trust team. Low ego, high standards, lots of shipping. WHY US? * Founding-team level ownership: You’re not “implementing tickets”, you’re shaping the product building high-value bets and stay close to customers. * Real societal impact: We’re building for the 80% of the workforce that doesn’t sit at a desk — and software has ignored them for too long. * Design-focused culture: Craft matters here. You’ll build software you’re proud to show. * Customer obsession: We build what serves operators and frontline teams — not engineering for engineering’s sake. * Backed by exceptional investors: We’re backed by top-tier VCs and investors like the founders of Framer and Indeed. * Remote or In-Office in Berlin: You can work remotely (CET/CEST ±1 hour only), or in our beautiful Berlin office, top equipment, 30 days holiday, impact from day 0. We embrace diversity and hire people based on their ability to perform a job. People of any race, gender, gender expression, sexual orientation, religion, age, disability, political opinion, or marital status are welcome at Bounti.
