Description
What This Role Is All About
We’re looking for a Backend Tech Lead who’s equally obsessed with architecture decisions and clean code, someone who can zoom out to design systems and zoom in to fix that one weird memory leak. You’ll lead a small but sharp team, drive the backend roadmap, and make sure our systems stay fast, lean, and battle-tested.
What You’ll Own
● Architect backend systems that handle India-scale traffic without breaking a sweat.
● Build and evolve microservices, APIs, and internal platforms that our entire app depends on.
● Guide, mentor, and uplevel a team of backend engineers—be the go-to technical brain.
● Partner with Product, Data, and Infra to ship features that are reliable and delightful.
● Set high engineering standards—clean architecture, performance, automation, and testing.
● Lead discussions on system design, performance tuning, and infra choices.
● Keep an eye on production like a hawk: metrics, monitoring, logs, uptime.
● Identify gaps proactively and push for improvements instead of waiting for fires.
What Makes You a Great Fit
● 6+ years of backend experience; 1–2 years leading engineers or owning major systems.
● Strong in one core language (Node.js / Go / Java / Python) — pick your sword.
● Deep understanding of distributed systems, caching, high-availability, and microservices.
● Hands-on with AWS/GCP, Docker, Kubernetes, CI/CD pipelines.
● You think data structures and system design are not interviews — they’re daily tools.
● You write code that future-you won’t hate.
● Strong communication and a let’s figure this out attitude.
Bonus Points If You Have
● Built or scaled consumer apps with millions of DAUs.
● Experimented with event-driven architecture, streaming systems, or real-time pipelines.
● Love startups and don’t mind wearing multiple hats.
● Experience on logging/monitoring tools like Grafana, Prometheus, ELK, OpenTelemetry.
Why company Might Be Your Best Move
● Work on products used by real people every single day.
● Ownership from day one—your decisions will shape our core architecture.
● No unnecessary hierarchy; direct access to founders and senior leadership.
● A team that cares about quality, speed, and impact in equal measure.
● Build for Bharat — complex constraints, huge scale, real impact.
