Senior React/Next.js Engineer
Mangaluru, Karnataka | Onsite | Full time
About the role
Delivery is organised into small, senior pods who own a client outcome end to end: scope, architecture, delivery, quality, and production. AI coding agents are an integral part of the delivery workflow, and much of the implementation is agent-generated. The value of this role lies in the work that surrounds generation: decomposing ambiguous business problems into buildable specifications, making architectural decisions, directing agents against those decisions, and ensuring that everything shipped meets production standards.
This position owns the web client of a multi-product consumer platform shipped across several regions: rendering and caching strategy, Core Web Vitals, the component and design-system layer, SEO, localisation, and front-end security. The role is problem-driven rather than ticket-driven. Most engagements are delivered on fixed-timeline terms, so scoping and estimation quality has a direct bearing on project outcomes. The emphasis throughout is on engineering judgment.




AI-augmented delivery: expectations
• AI coding agents are used daily as a core part of delivery. The critical skills are the specification that goes into generation and the review that follows it.
• Full ownership is expected for all code shipped under this role, regardless of how it was produced. Accountability for correctness, security, and maintainability rests with the engineer, not the tool.
• A key competency is identifying code that appears correct but is not: output that compiles, passes the happy path, and yet conflicts with framework fundamentals, introduces security exposure, or degrades at scale.
• All AI-assisted work is expected to be fully explainable and debuggable by the engineer who ships it.
Key responsibilities
• Outcome ownership: scoping, architecture, agent-directed implementation, review, testing, and release for web features, delivered end to end.
• Rendering and caching
