Mentorship from senior engineers

Job summary

InvestEngine is a London-based fintech expanding its pensions team with a Senior Frontend Engineer. You will own customer-facing pension journeys in React and TypeScript, collaborate across Product, Design, QA and Operations, and work with backend engineers to shape API contracts.

The role emphasizes ownership, building multi-step forms, and implementing testing, with AI coding tools and a remote-first setup. Fluency in English (B2+) and Russian is valued.

Qualifications

• 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).
• Strong ownership: you clarify unclear requirements before you start and see features through to production.
• Clear communication with engineers and non-technical stakeholders.

Responsibilities

• 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.
