Frontend engineer for pensions

We’re a London-based fintech on a mission to make ETF investing simple and accessible. Over 150,000 clients have trusted us with over £3.5 billion in assets — and we’re just getting started. We’ve been featured by MoneyWeek , Finder and Forbes , and we’re growing fast with big ambitions. We’re looking for a Senior Frontend Engineer to join our Pensions Team as its first dedicated frontend engineer. The team looks after around 100,000 SIPP accounts and thousands of pension transfers every month.

• Build and maintain customer-facing pension journeys in React and TypeScript
• Own features from refinement to production, shipping web in the same sprint as backend
• Agree API contracts , states and error handling with backend engineers and designers
• Build complex, multi-step forms for account opening, transfers and declarations
• Write unit and component tests, and release safely behind feature flags
• Monitor features in production and fix issues quickly
• Work in a large, long-lived codebase and follow our documented frontend architecture
• Use AI coding tools (Claude Code, Codex) in daily work — and review what they produce
• Set frontend review and testing practices in the team, and onboard our next frontend engineer
• Collaborate with Product, Design, QA, Operations and the wider frontend group

• Commercial experience with React and TypeScript as your main tools over the last 2+ years, in a large, long-lived codebase
• Production experience with a state manager beyond component state (Effector, Redux or similar)
• Solid REST API integration skills, including loading and error states
• Experience working closely with backend engineers — discussing and shaping API contracts , not just consuming them
• Experience building complex or multi-step forms in production
• Unit or component testing as part of your daily work (Jest, React Testing Library or similar)
• General understanding of web accessibility (semantic HTML, keyboard navigation, ARIA)
• Experience working within a documented frontend architecture
• Strong ownership: you clarify unclear requirements before you start and see features through to production
• Clear communication with engineers and non-technical stakeholders
• English B2+ and fluent Russian
• Будет плюсом: Hands-on backend experience — commercial or personal projects; Experience building a Backend for Frontend (BFF) layer; Experience planning frontend architecture and breaking work down for other engineers; Experience with Effector; Playwright or other end-to-end testing tools; Feature flags and error monitoring (GrowthBook, Sentry or similar); React Native experience; Experience in fintech or another regulated industry — not required, we’ll get you up to speed

• Impact from day one — own the web side of a business-critical pensions product
• Real ownership — shape how frontend works in the team from the start
• Growth — onboard and mentor the next frontend engineer joining the team
• Modern tooling — TypeScript, React, Effector, Jest, Playwright, Storybook, Claude Code and Codex
• Remote-first and flexible — work from anywhere, at your own pace
• Unlimited vacation — take time off when you need it, no fixed limits
• Supportive team — thoughtful, skilled colleagues who care about quality and results
