About the role
Vahan is India's largest AI-powered recruitment platform for blue-collar workers — backed by Y Combinator, Khosla Ventures, Temasek, and Bharti Airtel. We help companies like Swiggy, Zomato, Rapido, and Zepto hire at scale using AI and automation. Our mission is to connect 300 million blue-collar workers to economic opportunity, and we're just getting started.
We're looking for a Senior Backend Engineer who wants to own critical systems end to end — not just ship features, but drive technical direction, fix real scale problems, and raise the engineering bar across the team.
What you'll do
- Own the design, evolution, and reliability of high-impact backend systems — from architecture through production support
- Drive high-level and low-level system design with a focus on scalability, correctness, and long-term maintainability
- Diagnose and resolve database bottlenecks in PostgreSQL; optimize schemas, queries, indexes, and data access patterns
- Design and operate real-time and batch analytics pipelines (ClickHouse or equivalent)
- Improve code quality through design reviews, code reviews, and hands-on refactoring — and introduce patterns that prevent recurring issues
- Own production incidents end to end: resolution, post-mortems, and long-term reduction in operational load
- Mentor engineers across teams and influence technical direction through reasoning and example
What we're looking for
- 7+ years of backend engineering experience with strong expertise in Node.js
- Deep experience with PostgreSQL, including performance tuning
- Track record designing and operating distributed systems in production
- Experience with RabbitMQ or similar messaging systems (strong plus)
- Hands-on exposure to ClickHouse or large-scale analytics systems (strong plus)
