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
