SDE 3/Tech Lead - Platform Engineering

About Fam (previously FamPay)

Fam is India’s first payments app for everyone above 11. FamApp helps make online and offline payments through UPI and FamCard. We are on a mission to raise a new, financially aware generation, and drive 250 million+ young users in India to kickstart their financial journey super early in their life.

We’re reimagining how the next generation experiences fintech—going beyond payments to build a lifestyle brand that blends money, identity, and everyday experiences into one seamless, intuitive journey.

Founded in 2019 by IIT Roorkee alumni, Fam is backed by some of the most respected investors around the world like Elevation Capital, Y-Combinator, Peak XV (Sequoia Capital) India, Venture Highway, Global Founder’s Capital and the likes of Kunal Shah, Amrish Rao as angel investors.

We're looking for a strong software engineer with an infrastructure mindset to build reusable platform services and engineering primitives that power product development across the company. This role is focused on designing and building foundational capabilities such as rate limiting, distributed locking, configuration management, feature flags, service discovery, and other shared platform services that can be adopted by multiple engineering teams.

This is not a traditional DevOps or operations role. Rather than operating large-scale production systems day-to-day, you'll be responsible for building robust, scalable, and extensible platform abstractions that enable engineers to move faster and build reliable products.

You'll work on complex distributed systems problems, design clean APIs and libraries, and ensure platform services can be confidently validated through thoughtful testing, failure simulation, and scalability verification.

Must Haves

5–8 years of software engineering experience with strong backend development fundamentals.

Strong proficiency in Go or Python, with experience building production-grade backend systems, frameworks, or internal platforms.

Solid understanding of distributed systems concepts including concurrency, consistency, fault tolerance, caching, rate limiting, locking, and service coordination.

Experience designing reusable libraries, services, or infrastructure abstractions consumed by multiple engineering teams.

Strong software design skills with emphasis on maintainability, extensibility, and clean API design.

Experience writing comprehensive unit, integration, and system-level test suites.

Ability to reason about edge cases, failure scenarios, race conditions, and system correctness.

Familiarity with cloud-native architectures, containerized environments, and modern engineering tooling.

Strong debugging, problem-solving, and system design capabilities.

Excellent collaboration and communication skills
