Unipaas is the AI-native payments platform built for vertical software. We help platforms and marketplaces turn payments from a back-office utility into a growth lever. Our unified, fully managed service lets them deliver branded payment experiences without redirects, multiple providers, or long integration timelines. Founded in 2020 by payments-industry veterans, we serve customers across the UK, Europe, and the US in education, healthcare, and field services. Our R&D is in Tel Aviv; commercial is in London.
Engineering at Unipaas
We move real money for merchants whose businesses depend on us, and in payments the cost of getting it wrong is real: clean architecture, deep systems thinking, attention to detail, and code that holds up in production. Our engineers are generalists who own the full lifecycle with high agency and end-to-end ownership. Agents are standard equipment here, not experiments: Claude Code, Cursor, Codex, and what comes next. The rest is public: our engineering principles, and how we hire.
About the Role
We're hiring a Software Engineering Team Lead, reporting to the VP of R&D. This is a hands-on leadership role: you lead a team building the systems that authorize, settle, and reconcile every transaction we process, and you keep writing and reviewing code while you do it. It fits how we think about advancement here. Engineers grow by taking on harder problems and more ownership, not by how many people report to them, and your job is to create that for the engineers on your team.
What You'll Do
- Stay hands-on: write and review code and own the architecture on our distributed, event-driven platform, in a multi-vendor, multi-method, regulated payments context.
- Own your team's delivery, what it builds, how it builds, and whether it holds up in production, and take your turn in the on-call rotation.
- Develop your engineers and help them advance: hand off real ownership, run 1:1s, give clear feedback, and recruit as the team grows.
- Set your team's technical direction and make the calls that span its systems.
- Raise the bar for how the team works with agents (Claude Code, Cursor, Codex, and what comes next), and contribute to the agent-driven flows that run in front of customers, not just behind the team.
What We're Looking For
- 7+ years in engineering, including 2-3 years leading engineers as a team lead, tech lead, or manager; the rest spent building production systems hands-on. You still own hard technical work yourself; the hands-on ability does not lapse when you lead.
- A track record of developing engineers and helping them advance: hiring, mentoring, giving clear feedback, and growing people's scope and autonomy.
- Deep proficiency in at least one modern language; comfort with TypeScript / Node.js (our stack) or the ability to ramp into it fast. We care more about how you think than which language you've shipped most.
- Solid grounding in distributed systems at production scale on a major cloud provider (we run on AWS): event-driven architectures, container orchestration, infrastructure as code, and the operational craft of running services in production (observability, debugging, incident response).
- Fluency with agentic engineering tools (Claude Code, Cursor, Codex, or equivalents) in your day-to-day work, and a considered view of how a team should use them. Not something you've tried, something you ship with.
Nice to Have
- Experience shipping AI or agentic features into production product surfaces.
- Background in fintech, payments, or marketplace platforms.
- Experience taking a team through real adoption of agents, beyond a pilot.
Why Join
Competitive compensation and serious professional development. Real ownership in an early-stage company where what you ship hits production fast and matters to customers, and the room to grow a team while you keep building yourself.
