About Saturn
Saturn is a Series A, Y Combinator-backed startup building the AI-native operating system for the £100B+ financial advice industry. We believe advice will always be human, and we build technology that makes human advisers extraordinary.
Advisers currently lose up to 70% of their time to administration and compliance. Saturn automates this, giving advisers back their most precious resource so they can focus on what they do best: serving clients. We are compliant by design, trusted by 500+ firms and 3,000+ advisers across the UK.
Our engineers are early and founding team members from Rippling, Cred, Postman, Gojek, and Slice. We are a small team that orbits together, moves with purpose, and holds a high bar.
About the Role
As a Senior Platform Engineer at Saturn, you own the backend architecture and infrastructure that the entire product runs on. You make architectural decisions that affect every service, set the technical standard for reliability and correctness, and build the foundation for Saturn's next phase of scale.
You are a backend engineer with deep fundamentals who builds the systems that everything else depends on. You design and own core financial services infrastructure: data pipelines, integrations with back-office and adviser platforms, and the reliable, secure services that underpin Saturn's compliance and workflow engine. You think in systems, obsess over correctness and reliability, and are energised by the challenge of building infrastructure that has to be right every time.
At the senior level, you drive architectural decisions, mentor other engineers on backend best practices, and ensure Saturn's platform can scale to support a custody product and international expansion.
What You Will Do
- Design, build, and maintain scalable backend infrastructure in Go and TypeScript. Make architectural decisions that serve the platform for years.
