Streamhub is a global analytics platform powering total audience measurement, planning and targeting for TV and streaming services. Our mission is simple: make video data actionable and accessible for the entire media ecosystem. We work with broadcasters, streaming platforms and advertisers in multiple countries, combining advanced analytics, AI and scalable engineering to solve complex problems in the advertising value chain.

We are in a growth phase, expanding our teams across Bangalore, London and Tokyo to reinforce our international and entrepreneurial culture.

The Role

We are looking for a Senior Frontend Engineer who builds software the way modern teams actually ship it: with AI agents as active collaborators in the development loop, not as afterthoughts.

This isn't a role where "AI-native" means occasionally prompting a chatbot. It means designing your architecture so that agents can read, modify, and verify your code — and catching their mistakes mechanically through typed boundaries, lint rules, and fast automated feedback loops.

You will own the frontend of a data-intensive SaaS product, shaping how complex audience and measurement data is visualised and interacted with. While primarily frontend-focused, you'll gain exposure to full-stack data engineering workflows across the AdTech and MarTech ecosystem.

As a senior member of the team, you will drive frontend architecture, set AI-native engineering standards, mentor fellow engineers, and directly influence product direction.

What You'll Do

Build and maintain modern React applications within a structured monorepo (Turborepo), using reusable, scalable components that are readable and modifiable by both engineers and AI agents.
Develop highly interactive, data-intensive user experiences using React Hooks, TypeScript, and modern frontend patterns — with typed API contracts generated from backend specs, not hand-written, keeping AI-generated code reliable at the boundary.
Collaborate with backend engineers through a server-side proxy pattern to integrate RESTful APIs and ensure seamless, secure data flow across the application.
Work closely with Product, Design, and Data teams to deliver intuitive and impactful user experiences, maintaining in-repo convention documentation (CLAUDE.md or equivalent per package) so both teammates and agents stay aligned on how the codebase works.
Design and implement robust frontend testing strategies — unit, integration, and end-to-end — giving agents a reliable feedback loop where they can verify their own changes rather than compound errors.
Build responsive, accessible, and cross-browser compatible applications across major platforms.
Integrate and optimise third-party libraries for data visualisation, analytics, and other business-critical functionality, preferring libraries whose components live as readable source in the repo rather than behind opaque APIs.
Contribute to frontend architecture, coding standards, and CI/CD improvements — including custom lint rules that mechanically enforce team and agent invariants, catching convention violations that style guides alone won't prevent.
Participate in technical discussions, code reviews, and mentoring, with a bias toward decisions that make the codebase more navigable for humans and agents alike.
Take ownership of application performance, reliability, maintainability, and scalability.
Continuously explore and adopt modern frontend technologies, tools, and AI-native engineering practices that keep the team's development loop fast and self-correcting.

You Have

Core Requirements

6+ years of professional experience building complex web applications, including significant hands-on experience with React and modern frontend development practices.
Strong expertise in React and React Hooks.
A working understanding of AI-native development practices.
Excellent knowledge of TypeScript, JavaScript (ES6+), and modern browser APIs.
Strong understanding of component-driven architecture, reusable design patterns, and frontend application scalability.
Experience integrating and debugging RESTful APIs in frontend applications.
Strong understanding of responsive design, cross-browser compatibility, and accessibility best practices.
Experience implementing automated testing strategies, including unit and end-to-end testing.
Experience optimizing frontend performance and troubleshooting complex UI issues.
Familiarity with Git workflows, code review practices, and Agile development methodologies.
Strong communication, collaboration, and problem-solving skills.
Ability to work effectively in a fast-paced startup environment with a high degree of ownership and autonomy.

Preferred Technical Experience

Experience with Tailwind CSS, Vitest, and Playwright for responsive UI development and automated testing.
Experience with Vite or similar modern build platforms.
Experience with server-state management and data fetching libraries (e.g. TanStack Query), client-side routing, and lightweight state management (e.g. Zustand).
Experience building with component libraries following the shadcn/ui pattern — components as owned source, not opaque dependencies.
Experience with complex data grids (e.g. AG Grid) and interactive data visualisation libraries (e.g. Highcharts or recharts).
Experience with Angular (v10+), particularly candidates who have worked across Angular-to-React migrations or multiple frontend ecosystems.

Experience working on analytics, reporting, BI, AdTech, MarTech, or SaaS products.
Experience building data-intensive applications and complex visualizations.
Exposure to CI/CD pipelines, observability, and modern deployment workflows.
Experience mentoring engineers and influencing frontend architecture decisions.
