•  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)
