Principal Engineer - Backend Technologies

If you want to scale systems processing lacs of TPS, serving millions of daily users in a profitable, well-capitalized near-Unicorn company straddling fintech, e-comm and UPI payments, this may be the role for you. Client Company is a profitable, rapidly scaling unicorn which is extremely well capitalized. Client has a very strong moat in the consumer lending space on the back of which it is entering into additional large markets such as E-comm and UPI. You'll design systems built for 10x100x growth, make the key technical trade-off calls, and stay deeply hands-on. Beyond building, you'll mentor engineers and work directly with founders and product teams to translate business goals into scalable, reliable systems. Responsibilities: - Design and evolve the platform architecture to support 10x100x growth - 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 its the right call, and drive adoption of better approaches. Requirements: - 7 to 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 - Bias for action - moves fast, makes sound decisions, owns outcomes end-to-end - Comfortable navigating ambiguity and evolving priorities in a startup environment - Strong problem-solving skills ability to break down complex technical challenges and arrive at pragmatic, well-reasoned solutions - Hands-on experience with platform engineering developer tooling, shared services, infrastructure abstractions, or internal platforms If you want to scale systems processing lacs of TPS, serving millions of daily users in a profitable, well-capitalized near-Unicorn company straddling fintech, e-comm and UPI payments, this may be the role for you.
