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.
Client company is now entering its next phase of growth from a fast-scaling startup to a robust, high-scale financial platform serving millions of users daily. 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.
This role is an opportunity to:
- Shape the next-generation architecture for a high-throughput fintech system
- Build systems designed to scale 10x–100x from current volumes
- Solve real-world problems across performance, reliability, and financial-grade security
Responsibilities
- Design and evolve the platform architecture to support 10x–100x 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 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
- 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
