About InvestEngine
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.
About the Role
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.
You’ll own our pensions web journeys end to end — from clarifying requirements with Product, Design and Backend to building, testing, releasing and checking how features behave in production. Your first big goal is the frontend scope of a pension administrator migration: new account-opening flows, updated legal documents and in-app changes for existing customers.
The team is backend-heavy, so you’ll be the frontend voice in technical decisions: shaping API contracts with backend engineers, setting how frontend work is reviewed and tested in Pensions, and later onboarding a second frontend engineer.
What You’ll Do
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
What We’re Looking For
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
Nice to Have
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
How We Work
We’re a lean, collaborative team where engineers have a real influence on product, architecture and engineering culture.
We value ownership, curiosity and continuous improvement. We start from the customer problem rather than the ticket, and we pick the simplest solution that works.
In Pensions, you’ll be the team’s frontend owner — the person who makes sure pension features reach customers on web at the same pace as the backend.
What We Offer
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
Hiring Process
Intro call with our Talent team
Technical interview with the Frontend team (about 1 hour, case-based discussion, no live coding)
Gamified cognitive assessment to understand how you think and problem-solve
Final conversation with our CTO
