Job description
Senior Product Engineer - Investments
About Kota
Kota is reimagining insurance and retirement benefits for the modern workforce. Through our two flagship products - Kota Platform, the first fully integrated benefits platform, and Kota Embed, our embedded insurance solution - we're making benefits more accessible, valued, and global.
Today, we power benefits for tens of thousands of employees at Europe's most forward-thinking companies, including Carwow, Tines, Zoe, and Remote. Founded in 2022, we've raised more than €20M from leading investors such as EQT Ventures, Eurazeo, Northzone, and Frontline, as well as founders and executives from Workday, Remote, Personio, OpenAI, and more.
The role & team
We're looking for a Senior Product Engineer to join the Investments team, building the infrastructure that powers workplace pensions, retirement savings and our spend product at Kota. It's a full stack role with a backend lean, your strongest expertise will be backend, but you'll work in the frontend when the product needs it.
The Investments team owns more than pensions. On one side, pension infrastructure is genuinely complex: multi-provider, multi-market and largely unmodernised. You'll design the systems that connect pension providers to employers and employees, covering contributions, fund data, payroll integrations and compliance across multiple markets.
On the other hand, you'll own our Spend product. This lets employers create allowances and issue cards to employees, who get a virtual Stripe card they can add to Apple or Google Wallet and spend in real time. It spans card issuing, wallet provisioning, transaction flows and the controls employers need to manage it. We want someone who starts with the customer, not the code, and proactively adds to the roadmap rather than just picking up tickets. This is an autonomous role, you'll be trusted to make product calls, not just technical ones.
What you'll do
Design and build the systems that power Kota's Investments products; pensions, retirement savings and Spend: contributions, onboarding, provider integrations, employer-facing configuration, card issuing and wallet provisioning
Own technical architecture for the Investments stream, integrating with external pension and savings providers as well as payment and card infrastructure (Stripe)
Contribute to frontend code (React + TypeScript) when a feature calls for it
Join client calls where it helps you understand or explain a problem, and proactively shape the roadmap rather than just picking up tickets
Use AI actively in your day-to-day work, for building, reviewing and speeding up how you ship
Contribute to code reviews and technical planning, and keep the systems you own stable and observable
Help shape how the Investments team works as it grows
What we're looking for
6+ years building backend systems in production (.NET 10, PostgreSQL, Azure/AWS), comfortable picking up frontend (React/TypeScript) when needed
Experience designing and maintaining integrations with third-party APIs
Strong understanding of data modelling, event-driven patterns, and building for correctness and auditability
A clear communicator who can talk to engineers and customers, and knows which version to use with which audience
A product mindset and a bias to bring ideas, not just execute them, proactively adding to the roadmap
You think carefully about reliability, security and compliance, and are comfortable with ambiguity and ownership in a fast-growing startup
AI-forward mindset, we use AI daily to build and improve our systems and expect you to as well
Why join us?
Technically interesting problem - pension infrastructure is genuinely complex: multi-provider, multi-market and largely unmodernised
Modern stack - .NET 10, PostgreSQL, React, TypeScript, Next.js, Azure/AWS, event-driven
Agency - we hire people and trust them. You'll own meaningful parts of the system end to end
Customer proximity - you'll see the impact of what you build, and hear directly from the people using it
High-quality culture - we care about clean design and thoughtful engineering
Impact from day one - we're a small, focused team. What you build ships fast and matters
AI-first - we invest heavily in AI tooling and token usage. We're not precious about the spend, if it helps you build better or faster, use it

Introductory call (30 mins): a casual chat with one or two of our product team
