Role Overview
You’ll be the technical leader for a real-time trading platform used daily by brokers across Rates & FX desks. The frontend is a large-scale React/TypeScript monorepo — dense data grids, real-time pricing via WebSocket and GraphQL subscriptions, and complex multi-panel layouts. You’ll set the technical direction and make sure the architecture scales as the product grows.
You’ll own the frontend architecture end-to-end: defining patterns, driving quality standards, removing technical debt, and enabling your team to ship confidently. You balance long-term technical vision with pragmatic delivery under real market conditions.
Role Responsibilities
- Own the frontend architecture: define component boundaries, state management patterns, and data-flow contracts across a pnpm/Turborepo monorepo
- Drive technical strategy for the platform — evaluate new tools, plan migrations, and make build-vs-buy decisions with clear rationale
- Set and enforce engineering standards: testing strategy (Vitest, Playwright, MSW), code quality (Biome, Knip, dependency-cruiser), and observability (Grafana Faro, OpenTelemetry)
- Design solutions for complex problems: real-time data rendering at scale, performant AG Grid configurations, efficient Redux-saga orchestration, and GraphQL subscription management
- Lead technical delivery across multiple workstreams — unblock teams, resolve cross-cutting concerns, and ensure consistency across packages
- Mentor and grow Senior Engineers through architecture reviews, pairing on hard problems, and creating space for others to make decisions
- Collaborate with Product, Architects, and backend teams (C#/.NET, GraphQL BFF) to shape roadmap priorities and negotiate technical trade-offs
Experience / Competences
Essential
- Deep React + TypeScript expertise — you’ve architected large-scale applications and made structural decisions you can defend
- Strong experience with Redux in complex, data-intensive UIs (sagas, selectors, normalised state, performance at scale)
- Proven ability to design and maintain monorepo architecture: package boundaries, dependency management, build orchestration with Turborepo/pnpm
- Production GraphQL experience (Apollo Client) — schema design collaboration, caching strategies, subscriptions, codegen workflows
- Experience defining and implementing testing strategies across unit, integration, and browser layers
- Track record of improving developer experience: build performance, linting/formatting automation, CI pipeline optimisation
- You’ve led technical migrations or platform upgrades without halting feature delivery
- Experience setting up or evolving frontend observability (RUM, tracing, error budgets)
- Strong communicator who can translate architectural decisions into clear rationale for engineers, product, and leadership
Desired
- Experience with real-time data systems (WebSockets, streaming updates, high-frequency UI rendering)
- Deep AG Grid expertise — custom renderers, virtual scrolling, enterprise modules at scale
- Exposure to financial/trading platforms or latency-sensitive environments
- Experience with Module Federation or micro-frontend architectures
- Familiarity with feature flag systems (Unleash) and progressive rollout strategies
- Backend awareness (C#/.NET, GraphQL resolvers, relational databases) sufficient to
- collaborate on API design
