● 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.
