The Role & Team
We're looking for a Senior Product Engineer (Backend) to join the Investments team — the stream building the infrastructure that powers workplace pensions and retirement savings at Kota. This isn't just backend plumbing. You'll be designing the products that connect pension providers to employers and employees at scale, handling contributions, fund data, payroll integrations, compliance logic, and provider onboarding across multiple markets. It's technically challenging and a space where good product design genuinely changes outcomes for thousands of people.
We're looking for someone with the ability to contribute to the product from start to finish. From initial product design with the rest of the team, architecture and API design, and validating that what we build solves real problems for our customers. The role requires someone who moves fast and ships but also thinks carefully about reliability and correctness because in financial services being precise matters.
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 endto-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. This is a senior role and we'll look to you for technical leadership as the team grows
What We're Looking For
6+ years building backend systems in production. We use .NET 8, PostgreSQL and Azure
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. You're comfortable owning infrastructure, not just code
You think carefully about reliability, security, and compliance
You thrive at designing the product as a whole, not just the backend APIS. We need someone that will take the initiative and make product decisions
Comfortable with ambiguity and ownership in a fast-growing startup
AI-forward mindset - We are constantly evolving how we how we use AI to build products and improve our systems and engineering practices. You should lean into that, be actively curious about it and want to help push it further

Raise the Bar — we push past good enough — expect more, move faster, raise the standard
Ownership — ask why, do the work, get the data, solve the problem, be an owner
