The Role

Snapmint is 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 10x–100x 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 and build systems designed to scale 10x–100x from current volumes

• Role Title: Principal Engineer

What You Own

• 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

What You Bring

• 10-14 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
• 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

• 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
