Job description

This role is for one of our clients

Industry: Software Development

Seniority level: Associate level

Experience: 3+ yrs

Location: Bengaluru, Karnataka, India, Chennai, Tamil Nadu, India (hybrid)

Job Type: Full-time

We may use artificial intelligence (AI) tools to support parts of the hiring process, such as reviewing applications, analyzing resumes, or assessing responses and identifying potential inconsistencies or verification signals in application materials based on available information. These tools assist our recruitment team but do not replace human judgment. Final hiring decisions are ultimately made by humans. If you would like more information about how your data is processed, please contact us.

You’ll build the product surfaces where customers model, build and run supply-chain decisions: complex, data-heavy workflows, editors, grids and app-building experiences. Your instinct shows in the UI, but your ownership doesn't stop at the browser: you'll shape the API and data contract behind each surface and own it in production. It's a senior role, with level set by what you demonstrate.

Requirements

• Data-heavy product surfaces end to end, from contract and UI to release and iteration


• Frontend architecture: component boundaries, state and data fetching, performance, accessibility


• Shared patterns and components, built with design and product, that make the next surface faster to ship


• The service side: APIs, data contracts, permissions and failure handling across layers, plus testing, observability and release safety

What We're Looking For

• Strong React and TypeScript/JavaScript fundamentals, below the framework layer


• Complex user-facing products you personally shipped and ran in production


• Credible backend ownership; Node.js/TypeScript helps, equivalent depth is fine


• Product thinking: you frame the user problem before choosing an implementation


• Startup experience, a hands-on ownership style and clear communication

Good to have

Micro-frontends, monorepos or shared component systems; developer tools, data products or workflow builders; SQL, multi-tenant SaaS and observability-heavy systems.

Location
