saturn - Product Engineer

• Build and ship high-quality product features end-to-end in Go, TypeScript and Python, spanning Saturn’s meeting capture, suitability reporting, compliance automation, and CRM surfaces. • Integrate LLMs and AI capabilities into user-facing features: prompt engineering, retrieval-augmented generation, structured document generation, and AI-assisted adviser workflows. • Collaborate closely with Product, Design, and domain experts to translate complex regulatory and adviser workflows into elegant, fast, reliable software. • Take full ownership of features from scoping through to delivery, estimating effort, identifying risks, and shipping to deadline. • Write clean, maintainable, well-tested code and contribute actively to code and design review cycles. • You are close to the product, close to the user, and close to the decision, your instincts shape what Saturn becomes. • Help shape product direction, you are close to the work and your perspective on what to build next matters. • Uphold our principle of being compliant by design: every feature you ship must meet the bar of the UK’s principles-based regulatory environment. • 3–4 years of experience in product or full-stack engineering, ideally at a fast-paced, product-led company. • Strong hands-on experience with Go and/or TypeScript in production environments. • Experience building AI-powered product features, LLM integration, prompt engineering, or delivering AI outputs in a user-facing context. • Ability to write maintainable, scalable, and well-tested code across backend and frontend services. • Strong product instincts, you think about the adviser experience, not just the technical implementation. • Comfortable working with cross-functional teams including Product, Design, and non-technical domain experts. • Clear communicator who can articulate technical trade-offs and move fast without breaking things that matter. • Self-starter who thrives with autonomy and is energised by ambiguity and pace. • Prior fintech, regtech, or regulated industry experience or SaaS is a strong plus but not required. • We care deeply about the culture we build. We hire people who are obsessed with doing great work, who seek truth over comfort, who earn trust rather than assume it, and who succeed and fail as one team.
