- Own systems end-to-end from the first design decision to production impact
- Lead system design discussions and set the long-term technical direction for the platform
- Identify scale bottlenecks early and drive solutions
- Mentor and elevate engineers through design reviews, code quality, and architectural thinking
- Partner directly with founders and product teams to turn business priorities into scalable systems
- Operate with high ownership in a fast-paced environment where priorities evolve quickly
- Drive projects independently own timelines, coordinate with teams, and see delivery
- Conduct rigorous code reviews and champion engineering best practices across the team
- Proactively identify gaps in the system and come up with concrete approaches to address them
- Solve technical problems across the company not just confined to a single pod
- Challenge existing architecture with data and reasoning push back when it’s the right call, and drive adoption of better approaches.
Requirements
- 7–12 years of experience in backend or platform engineering
- Strong computer science fundamentals (preferably from IIT, BITS, NITs)
- Strong proficiency in backend development (Node.js, Java, Go, or equivalent)
- Proven experience scaling systems through high-growth startup phases (1→10 or beyond)
- Track record of building and owning critical platforms or systems from scratch
- Exposure to high-volume transactional systems; fintech or lending is a strong plus
