As a Senior Backend Engineer, you will own substantial backend systems and platform capabilities from design through to reliable production operation.
You will work closely with product engineers, AI engineers, domain experts and engineering leadership to turn complex financial and regulatory problems into durable systems.
You will not wait for every problem to arrive as a complete technical specification. You will be expected to understand the business objective, identify the important constraints and make sound engineering trade-offs.
Your work will help determine whether Saturn becomes a collection of useful applications or a coherent platform capable of supporting increasingly important financial workflows.
What we’re looking for
4+ years building and shipping customer-facing software in production
Experience owning a substantial product area from an ambiguous problem through to adoption and iteration
Strong frontend engineering depth in TypeScript and modern web frameworks
Strong full-stack capability, with the judgement to work across the system where needed
Experience contributing to frontend architecture and shared engineering foundations
A record of making product decisions without relying on complete specifications
Strong product judgement and the ability to explain trade-offs clearly
Experience working closely with design while maintaining technical ownership
Evidence of improving performance, accessibility and interaction quality in production products
Experience building reliable interfaces around complex data, workflows or permissions
Experience investigating production issues and translating findings into product improvements
A record of scoping and delivering work measured in months from a business or customer objective
Strong written communication, with the ability to document product and technical reasoning
Experience improving standards across code review, testing, release and client-facing quality
Comfort owning decisions with incomplete information and real deadlines
Experience mentoring engineers and improving the quality of a team
Experience working at startup pace without sacrificing judgement or craft
Preferred experience
Building software for financial services, healthcare, legal or another regulated domain
Financial advice, wealth management or investment products
Building AI-native products or interfaces around probabilistic systems
Designing human review, approval or exception-handling workflows
Mobile product development
Complex forms, document workflows or data-heavy applications
Design systems and frontend platform architecture
Building enterprise products with sophisticated permissions and firm-specific configuration
Accessibility standards and performance optimisation
Taking a product from early adoption to broad production use
What success looks like
Success in this role means:
advisers can complete more of their working day inside Saturn
complex workflows become simpler without losing regulatory control
product decisions are grounded in evidence and clear reasoning
client-facing engineering moves quickly without accumulating avoidable inconsistency
the web and mobile experience feels coherent across products
performance, accessibility and interaction quality improve as the product scales
production issues are understood quickly and influence what gets built next
engineers increasingly build on shared foundations rather than fragmented product patterns
advisers trust Saturn with increasingly important parts of their work
the product becomes harder to replace because it is deeply integrated into how firms operate
Saturn develops a strong product engineering culture with a high bar for craft, ownership and judgement
