Senior Backend Engineer

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)
• AWS deployment and operations experience (plus)
• Strong debugging, observability, and production reliability instincts
• Someone who improves messy systems incrementally, thinks in trade-offs, and influences without authority

Competitive pay · Unlimited PTO · Comprehensive medical insurance · Monthly wellness leaves
