● 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.

● 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.
