We’re looking for a Senior Frontend Developer to join an established team working on a B2B fintech product. The team owns the user journey from signup to the first key action, including onboarding, growth experiments, and analytics. It works closely with product, design, and data, and engineers drive initiatives from start to finish.

• Build and ship user-facing features in complex production React applications: multi-step flows, routing, form state

• Drive larger initiatives across several sprints: plan the scope, split it into tasks, and align with other teams

• Own initiatives and communicate progress proactively; raise risks early

• Work with legacy code, including discovery and incremental improvement

• Contribute to activation and conversion improvements, including A/B tests and growth experiments

• Balance delivery speed with long-term code quality

• Participate in code reviews and contribute to engineering standards

• 5+ years of commercial experience in front-end development

• Strong hands-on experience with React 18 and TypeScript (plus Webpack)

• Proven track record of shipping user-facing features in a product team

• Experience with complex production apps: multi-step flows, routing, form state management

• Product thinking: you understand how users move through the product and how experiments improve conversion

• Experience leading long-running initiatives, from planning to delivery, together with other teams

• Confident working in older codebases where not everything is documented or clearly defined

• Active use of AI-assisted tools (Claude Code, Cursor, Codex, etc.) to optimize day-to-day development workflows

• Upper-Intermediate level of English or higher

• Proactive, ownership-driven communication

‍

‍Nice to have:

• Experience with product analytics and marketing tools (e.g., Mixpanel, Segment)

• A/B testing and growth experimentation

• AWS Cognito, OAuth, or IAM

• React Native or other mobile exposure

• Multi-country products (localisation, regional compliance)
