Senior Frontend Developer | React | Global Investment Manager | London, hybrid
Our client is a forward-thinking global firm redefining the future of finance through technology.
They are looking for an experienced Senior Front End Engineer (React) who can set the technical direction for the front-end, champion best practices, and still enjoy being hands-on.
Someone who obsesses over clean design, performance and scalability, and is comfortable leading from the front.
📍 Location: London City, hybrid working (3 days per week in the office)
💷 Package: Highly competitive base + bonus + benefits
⌛ Permanent Role
In this role:
You’ll be the go-to technical leader for front-end engineering within a cross-functional product team, shaping the architecture, tooling and standards for user-facing applications used by investment professionals across the business.
The team is currently re-architecting its stack to be fully cloud-native (AWS), with React and TypeScript on the front end and Python-based services on the backend.
You’ll work in a culture that values engineering excellence – TDD, clean code, pair programming, thoughtful code reviews – and your voice will carry weight in how the platform evolves.
What You’ll Do:
- Lead the design and development of complex, high-performance React applications using React, TypeScript and modern front-end libraries.
- Define and drive front-end architecture, standards and best practices, ensuring quality, consistency and reusability across products.
- Collaborate closely with Backend, UX and Product to refine user journeys, ensuring interfaces are intuitive, performant and accessible.
- Partner with portfolio managers, researchers and analysts to translate complex domain problems into elegant, user-focused solutions.
What You’ll Bring
- Significant experience, at least 6 years', building large-scale React and TypeScript applications, ideally in complex or data-heavy domains.
- Experience within Financial Services environments is highly advantageous e.g. Investment banking, trading, asset management, etc.
- Deep knowledge of React, TypeScript, state management (e.g. Redux or similar), Apollo Client and GraphQL/REST APIs.
- Experience in cloud-native environments (AWS or Azure), and how front-end and backend services fit together in distributed systems.
- Strong understanding of front-end performance optimisation, including data streaming (WebSockets, server-sent events, chunked responses).
- Solid experience with testing strategies (unit, integration, E2E) – Playwright, Cypress or similar tools a plus.
- Bonus points for experience with design systems (e.g. Material UI) and data visualisation libraries.
About You
- A hands-on technical leader who’s comfortable making architectural decisions and backing them up with code.
- Confident owning front-end initiatives end-to-end, from discovery and design through to delivery and optimisation.
- Collaborative and pragmatic - able to work across product, UX and engineering teams without ego.
- Curious, always learning, and keen to improve both the codebase and the way the team works.
