Position: Senior Software Engineer, Full Stack

Location: Hyderabad

Working Days: Monday to Friday

Experience Required: 4 to 6 years

Our client powers enterprise-grade events at scale, from virtual conferences to hybrid summits, with real-time video, live streaming, and complex audience engagement. They are looking for a senior engineer who writes great code, knows when to lean on AI and when to catch it slipping, and genuinely cares about shipping products that hold up under 10,000 concurrent users.

What you'll do
- Own features end-to-end. From initial design to production reliability, you write the code, manage the deployment, and own the 3 AM page. This includes React frontends, Java backends, and the cloud infrastructure tying them together.
- Build for scale and real-time. Design and implement systems that handle thousands of concurrent users on large-scale events, with low-latency WebSocket connections, effective pub/sub patterns, and resilient backend services.
- Deliver high-quality frontend experiences. Build highly interactive React apps with video,



live streaming, and real-time engagement, optimised for performance, bundle efficiency, and responsiveness.
- Work AI-assisted, not AI-dependent. Use tools like Cursor or Claude Code to accelerate routine work. Bring your senior judgment to audit what they produce, catching logic fragmentation, stale closures, misused concurrency primitives, and edge cases that agents confidently skip over.
- Shape architecture. Author Tech docs and architecture that drive how features get built, not just by you, but by the team and AI agents working alongside it. Enforce structural integrity across the codebase.
- Follow engineering best practices. Write clean, appropriately tested code, unit tests, meaningful PR reviews, and documentation that doesn't go stale.
- Collaborate closely. Work directly with designers and product managers to iterate fast. Be product-obsessed enough to push back on specs when something doesn't
