tem

📈 Who We Are: We are rebuilding the energy transaction, making it transparent and fair. Our goal is to put power back where it belongs, in the hands of customers and to take on one of the most critical problems of our century, access to low cost electricity. tem exists to fix a broken global energy market that’s long favoured legacy operators, intermediaries, and opaque pricing. Today’s electricity system was not designed for rapid decarbonisation, AI-driven efficiency or fair access for the actual users - businesses and generators. We’ve built the first AI native transaction infrastructure to reinvent how electricity is bought, sold and priced. Our technology is designed to cut out the inefficient fees, automate complex market flows, and bring transparency and fairness to energy transactions at scale. In late 2025, after extraordinary growth, we closed a $75 million Series B - led by Lightspeed Venture Partners with participation from Albion, Atomico, Allianz, Hitachi Ventures, Hitachi Ventures, Schroders Capital and others - positioning us for global expansion, deeper product innovation and category leadership. We’re scaling internationally and building toward a future where AI-driven infrastructure is foundational to electricity markets worldwide. Since launch, our modern utility product, known as RED, has already facilitated thousands of business customers and billions in energy transaction value, proving that modern software and AI can transform an industry built on legacy systems. At tem, we’re not just building another energy company, we’re rearchitecting market infrastructure so that transparency, efficiency and sustainability become the default, not the exception. 🏅 THE ROLE: We're hiring a Senior Staff Software Engineer for Origination & New Products. This is a hands-on technical leadership role, not a people-management one. You'll lead the Origination & New Products squad through ambiguous, no-precedent build work - deep Rosso integration, pricing capability, and deal-gating risk tooling. You won't own hiring, performance, or comp for anyone in the squad; you'll lead through technical direction, judgement, and execution. Beyond the squad, you'll be a strategic partner to the Engineering Manager, turning company-level targets into engineering outcomes - starting with growing origination volume through new products over the first 12 months, and later supporting the team as Sell Side expands internationally. You'll lead a new three person squad to help you deliver your goals. You will: * Own the delivery for new product categories * Lead technically through execution - design, build, and ship alongside the squad, not just direct it. * Translate ambiguous, commercially-driven problems into a shape the squad can deliver against. * Partner with commercial and product stakeholders to keep new-product work tied to real pipeline outcomes. * Mentor the squad's engineers and raise technical standards, without owning their performance or career progression. You will report into the Engineering Manager, Sell Side. 🚀 RESPONSIBILITIES: Lead through execution * Drive the Origination & New Products squad's technical direction on deep integrations with other internal services * Stay hands-on: design, build, and review the hardest parts of the new-product build sequence yourself. * Take a company target ("grow origination volume through new products") and break it into a sequenced, deliverable plan without needing to be told how. Build for ambiguity and risk * Design systems for categories that don't exist yet at tem - Unlocking TWh’s of new pipeline - where the spec is being written as you go. * Make judgement calls on commercial risk in deal-gating tooling, not just deliver what's asked. * Prevent domain drift as new product categories are added, keeping shared language and clear boundaries. Partner beyond the squad * Work directly with the Engineering Manager and commercial stakeholders to keep new-product delivery tied to origination pipeline outcomes, not just shipped features. * As Sell Side expands internationally, represent the technical view in conversations with new-market stakeholders and partners. * Mentor engineers in the squad and raise engineering standards, while staying on the individual-contributor track. 🎯 REQUIREMENTS: Must haves * Proven technical leadership at Staff or Senior Staff level, with evidence of leading complex, ambiguous initiatives to real business impact - not just technical execution in isolation. * Comfort operating without a spec: able to take a broad, undefined opportunity and shape it into something buildable. * Sound commercial judgement - able to reason about deal risk and revenue impact, not just delivery. * Deep enough platform fluency to integrate against a complex, business-critical system * Track record leading a squad or team technically through direction and mentorship, without necessarily holding formal people-management responsibility. * Strong written and verbal communication - comfortable being the technical voice in front of commercial stakeholders and, over time, external partners. * Comfortable in our core stack: Python, AWS serverless (Lambda, API Gateway, DynamoDB, EventBridge), and event-driven architectures - the same stack Rosso and the rest of Sell Side build on. Bonus points * Experience in energy, fintech, or another regulated, high-stakes commercial domain. * Experience taking a product or company into a new international market. * Exposure to workflow orchestration, event-driven systems, or real-time pricing engines. * Experience originating new product lines from scratch rather than only scaling existing ones. ✨ BENEFITS & PERKS: * Competitive salary - our current band for this role is £117,850 or equivalent in local currency. * We review salaries twice a year using real-time market data, with transparent, consistent pay for the same role and level. * Stock Options - everyone on the team has ownership in our mission. * 25 days holiday + public holidays - Swap public holidays for ones that matter most to you. Plus, get an extra day off for your birthday 🎉. * Remote & flexible working - We’re fully remote with clear core hours, and no internal meetings on Friday afternoons. * Home working & wellbeing budgets: * Up to £1,200 / €1,200 annually to upgrade your remote setup (co-working passes, equipment, etc.). * Up to £150 / €150 monthly on anything that supports your wellbeing - from therapy to gym memberships to meditation apps.   🗣️ INTERVIEW PROCESS: Our processes normally take around 2-3 weeks from first call to offer - please let us know about any adjustments to timelines that may be required. 1. First call with our Talent Team (30 Mins). This is to understand your experience, motivations, and discuss the role in more detail. 2. Behaviour Interview with our Engineering Managers (60 Mins). This is your chance to really understand the role, the expectations, and ensure alignment on ways of working. 3. Technical Interview with the Team (75 Mins). You’ll meet with potential peers in this session and will discuss technical topics and experiences. 4. Culture-Add Interview with Stakeholders (45 Mins). The final session will be with two cross-functional stakeholders, and will explore how your values align with ours, and is designed to be a genuine two-way conversation, your chance to understand what it’s really like to work at tem. We welcome applications from people of all backgrounds, experiences, and identities, including those that are traditionally underrepresented in the tech and energy sectors. If you’re excited about this role but not sure you meet every requirement, we’d still love to hear from you. Your unique perspective could be exactly what we’re looking for.

Primer

An Introduction to Primer Primer is the unified infrastructure for global payments. We give finance and payments teams the visibility and control to reduce complexity, improve performance, and capture more revenue - all from a single platform. Backed by Sofina, Peak XV Partners, ICONIQ, Tencent, Accel, and Balderton, we're building the payments layer the world's best companies rely on. Watch our showcase > Read up on our $100m Series C Learn more about our culture > WHICH TEAM WILL YOU BE JOINING? You'll join Infrastructure, the team that owns the platform every other Primer engineer builds and ships on. CI/CD, deployment, internal tooling, ephemeral environments: if it's how code gets from a laptop to production safely, it's ours. We operate the way the rest of Primer does. Remote-first, async, high autonomy, low bureaucracy. You build it, you own it, and that includes running it in production. You'll report to the Engineering Manager for Infrastructure & Data and work alongside a small group of senior infrastructure engineers. What makes this interesting right now is the human-AI development loop. Coding agents are changing how software gets built, and we want someone to own how that actually works at Primer rather than bolting it on. That part of the role is yours to define. WHAT WILL YOU BE DOING? * Own Primer's internal developer platform end to end: the CI/CD pipelines, deployment workflows (canary, blue/green), self-service tooling and ephemeral environments that every engineer here depends on to ship. * Build the human-AI development loop. This is the most open part of the role: the tooling and automation that let engineers work effectively alongside coding agents, and the patterns that make agent-driven workflows fast and safe at Primer. * Treat developer productivity as a measurable system. Instrument it, find where delivery actually slows down, and ship the changes that fix it instead of guessing. * Take real operational ownership. You'll join the Core Infrastructure on-call rotation and own the reliability of what you build. * Set the technical direction for how Primer's engineers build and ship, and bring less experienced engineers along with you as you do it. * Improve how engineers write code, not just how they ship it. Partner with product teams to make the tools, frameworks and internal APIs they use everyday more ergonomic, and help reduce the friction of building features at Primer. * Build Primers paved roads. Reduce the application boilerplate engineers write, shape standards around how services are built and configured, and own the golden-path tooling that lifts efficiency across every team. * Work in the open across a fully distributed team, making your decisions and trade-offs visible rather than holding them in your head. WHAT WE'RE LOOKING FOR * Strong cloud infrastructure experience. AWS is preferred; we'll also consider strong GCP backgrounds. * Hands-on Kubernetes experience. * Infrastructure-as-code as a working tool, not a buzzword. Terraform is preferred, but Pulumi, CloudFormation, Ansible or similar are fine. Not having Terraform specifically is not a blocker. * CI/CD as a core competency. You've owned the build, test and deploy workflow and preview environments, not just used them. * A history of measuring and improving delivery, using DORA, SPACE or a similar framework to back the work up. * Comfortable owning production systems and being part of an on-call rotation. * A genuine software engineering background. You've built and maintained applications or products, not just infrastructure tooling. * You can reason about what makes code pleasant to work with. This is what lets you build AI and developer tooling that engineers actually want to use. * An async-first communicator who works well in a remote, distributed team. Nice to have: * Hands-on experience building with AI or agent tooling, or working directly with LLM-based development workflows. This field is new, so real curiosity counts alongside real experience. * Familiarity with MCP servers and agent integration patterns. * Payments, fintech or other regulated-industry experience. YOU MAY NOT LIKE IT HERE * We're remote-first and async-first. Nobody is looking over your shoulder, and nobody is going to hand you tightly scoped tasks. You own your work from problem to production. * This role carries real operational weight. You're on call for what you build, and when something breaks at an awkward hour, that's yours too. * The AI-enablement side of this is genuinely undefined. There's no playbook yet. If you want a clear, settled remit, this isn't it. If you want to write one, it is. * Pace and ambiguity are constant. Priorities shift as we learn, and you'll often be making calls without complete information. ✅ A TYPICAL INTERVIEW PROCESS * An initial intro call with a Talent Partner * An interview with the Hiring Manager * Challenge Stage - Contextualised to the role * A final, values-alignment interview WHAT'S THE CULTURE LIKE AT PRIMER? We're building a culture where people can do their best work and be proud of the impact they have. You'll be working with people who are mission-driven, smart, and reflective, and who are genuinely invested in building exceptional products and delivering success for our merchants. We work remotely, and have done since day one. We believe that building a successful, profitable company goes beyond proximity. We invest in our relationships through great remote working practices and thoughtfully designed face-to-face time, including workations, our annual company retreat, and access to co-working spaces across most major cities. The work is challenging. Scaleups are a challenge, and building category-defining products is a challenge. But there's a meaningful difference between a challenge and a struggle. At Primer, the right challenge comes with the right support: strong onboarding, a collaborative environment, and a team that is genuinely invested in your success. It's never something you face alone. OUR BENEFITS 🌍 We are fully remote and globally distributed; and have been since day one 💰 Competitive share options 🌴 Uncapped holiday, with 25 days minimum to be taken 🗣️ Co-working space access across major cities 📅 Workations & Company Retreat 💻 The best equipment for your role 🏠 £500 towards your home office setup 🔎 Generous learning budget 🏥 Private Medical Insurance 📈 A broad set of additional perks and benefits (depending on location) DON’T MEET EVERY SINGLE REQUIREMENT? At Primer, we're dedicated to building a diverse, inclusive, and authentic workplace. If you're excited about this role but your experience doesn't align perfectly with every qualification listed, we encourage you to apply. You may be the right candidate for this or other roles. Primer is committed to the equal treatment of all current and prospective employees and adopts a zero-tolerance approach to discrimination, regardless of age, disability, sex, sexual orientation, pregnancy and maternity, race or ethnicity, religion or belief, gender identity, marriage and civil partnership, or any other background or belief.
