Kota is looking for a Senior Product Engineer (Backend) to join our Investments team. You'll build the core infrastructure that powers our workplace pensions and retirement savings products, designing systems that connect pension providers to employers and employees at scale across multiple markets.
What You'll Do
- Design and build the backend systems that power Kota's pension and retirement savings products including contribution flows, onboarding flows, provider integrations and employer-facing configuration
- Own technical architecture decisions for the Investments stream
- Integrate with external pension and savings providers, building robust, well-tested integrations that handle the messiness of real-world financial systems
- Collaborate closely with the Product Lead, frontend engineers, and the broader integrations team to deliver features that work seamlessly end-to-end
- Continuously improve the stability and observability of the systems you own
- Contribute to code reviews, technical planning, and a culture of high standards without bureaucracy
- Help shape how the Investments team works and provide technical leadership as the team grows
What We're Looking For
- 6+ years building backend systems in production
- Experience designing and maintaining integrations with third-party APIs
- Strong understanding of data modelling, event-driven patterns, and building for correctness and auditability
- Cloud experience with Azure or AWS, comfortable owning infrastructure, not just code
- Think carefully about reliability, security, and compliance
- Thrive at designing the product as a whole, not just the backend APIs, and take initiative to make product decisions
- Comfortable with ambiguity and ownership in a fast-growing startup
- AI-forward mindset, actively curious about using AI to build products and improve systems and engineering practices
Technical Stack
- .NET 8
- PostgreSQL
- Azure
- AWS
