Job description

Software Engineer — Frontend (React / React Native / TypeScript)
Location: Mumbai
Hybrid: Yes (4 days WFO)
Experience: 5–8 years
Team: UI/UX Engineering — Capital Markets Platform

About the role

We are looking for a hands‑on senior engineer who treats the front end as a first‑class engineering discipline – someone who can ship pixel‑precise, fully‑tested features across a complex web platform and a mobile companion app, and is energised by the challenge of building real‑time, data‑heavy UI for institutional finance users. You will join a tight‑knit frontend group that owns a large‑scale TypeScript monorepo powering a desktop‑class web application (deployed inside a multi‑window desktop shell), a React Native mobile companion, and a Storybook‑driven component library that ties them together. The work is deeply technical, deeply user‑facing, and visibly impactful – our users make decisions worth millions of dollars on screens we build.

What you’ll work on

• Build production features across the stack – from data‑grid blotters showing thousands of live‑updating rows, to portfolio analytics dashboards, to mobile workflows for on‑the‑go users.
• Own real‑time data pipelines on the client – Web Workers, IndexedDB‑backed live queries (Dexie + Observable patterns), WebSocket‑driven state, all under tight latency and memory budgets.
• Treat performance as a feature – virtualised grids, memoised render trees, careful re‑architecture when something slows down; profiling and fixing isn’t optional, it’s the job.
• Design and evolve shared packages – we ship 25+ internal libraries (components, hooks, utilities, domain‑specific modules); your work routinely benefits every team using them.
• Drive quality – Jest + React Testing Library for units, Playwright for end‑to‑end, snapshot discipline, coverage ratchets in CI. Tests are written by the author, reviewed by peers, and required before merge.
• Review code with intent – RFC‑style design discussions, thoughtful PR feedback, and a willingness to push back when something can be done better.
• Collaborate cross‑functionally with product managers, designers, and back‑end teams to ship features end‑to‑end.

Tech you’ll work with day‑to‑day

• React 18, TypeScript 5.x
• styled‑components for the web client
• React Native + Expo for the mobile companion app
• Rush + PNPM monorepo with 25+ internal packages, code generators, and a CI build matrix
• AG Grid Enterprise for high‑performance data grids and Highcharts for visualisations
• Dexie / IndexedDB for client‑side persistence and reactive live queries
• Web Workers for off‑main‑thread message processing
• OpenFin (HTML5 desktop runtime) for multi‑window, multi‑monitor desktop deployments
• Jest, React Testing Library, Playwright for testing; Storybook for component‑driven development
• Jenkins, SonarQube, ESLint, Prettier, Conventional Commits in the delivery pipeline

What we’re looking for (must‑have)

• 5–8 years of professional software engineering, with a substantial portion (3+ years) building production React applications in TypeScript.
• Deep React fundamentals – hooks, rendering model, reconciliation, suspense, performance characteristics.
• Strong TypeScript – generics, conditional types, mapped types, discriminated unions; you reach for type safety, not any.
• Production React Native experience – good to have knowledge of developing and shipping mobile apps, ideally maintained across both iOS and Android, and working knowledge of native modules, build pipelines, and the realities of mobile.
• Solid CSS and design‑system sensibility – you can read a Figma file, build it accessibly, and know when to push back on a spec.
• Testing as a habit, not a chore – unit, integration, and end‑to‑end.
• Comfort in a monorepo with shared packages – versioning, dependency graphs, the discipline of not breaking your neighbours.
• Git fluency – rebasing, conflict resolution, conventional commits, code review etiquette.
• Clear written and verbal communication – most of our team operates across multiple time zones; words on a PR thread are how decisions get made.

Nice‑to‑have (any one of these is a real plus)

• Java exposure – even reading‑level fluency is valuable.
• Experience with AI‑assisted development tooling – Claude Code, Cursor, Windsurf, GitHub Copilot, or similar agentic / coding‑assistant workflows.
• Capital markets / financial‑services / fintech domain knowledge – buy‑side or sell‑side, OEMS/EMS, portfolio management, risk, compliance, trading workflows, market data, reference data, settlement, or anything adjacent.
• Real‑time / data‑grid heavy applications – experience building UIs over WebSocket / SSE streams, with virtualised tables of thousands of rows.
• Desktop‑app development – Electron, OpenFin, Tauri, or similar.
• Open‑source contributions to the React / TypeScript / RN ecosystems.

How we work

• Quality over speed – we ship when it’s right, not when it’s first.
• Small PRs, fast feedback – no week‑long branches if we can help it.
• Tests with every change – non‑negotiable, but supported with strong tooling.
• Documented decisions – design docs for non‑trivial work, ADRs for cross‑cutting changes.
• Conventional commits + automated changelogs so release notes write themselves.
• Modern tooling, with a willingness to evolve it – we replace what no longer serves us, and we expect you to push for those replacements.

What you can expect from us

• A team of senior engineers who care about craft.
• Direct, written feedback on your code and your ideas.
• Latitude to choose the right tool for the job – and the responsibility that comes with that.
• Visible, business‑critical work used every day by sophisticated users.
