Tech Lead - Architecting the Next Billion-User Systems

About Role

- This isn t a manage the team role. This is a build, break, scale, and own every damn line of backend logic role.
- Our systems run on Node.js and AWS, and your job is to make them bulletproof under traffic.
- If you re the kind of engineer who gets angry when a request takes 500 ms... keep reading.

What You ll Do

- Architect Node.js systems that scale from zero to millions - resilient, battle-tested, and ready for anything.
- Tear apart bottlenecks before they become outages.
- Build a backend that auto-heals, scales without begging, and doesn t melt at 1M RPM.
- Own the full lifecycle - from feature idea to scaling in production.
- Guide engineers, set the technical bar, and call out flawed designs.
- Think ahead: design for chaos, failovers, and ugly realities before they happen.

You re Built for This If

- You ve watched a system catch fire and brought it back with grit and caffeine.
- You ve scaled services under brutal load and lived to tell the story.
- You know Node.js beyond frameworks - profiling, event loop internals, async churn.
- You can rip apart AWS quirks (RDS slow queries,



ElastiCache meltdowns, S3 limits) in your sleep.
- You don t wait for instructions - you see a mess and fix it.

Bonus XP (Things That Impress Us)

- You ve taken systems to 100M+ users or 6-digit RPS.
- You ve crushed AWS bills without slowing down a single request.
- You ve built real-time madness: Kafka, Kinesis, WebSockets.
- You ve designed secure-by-default infra: IAM, VPC, KMS.

What s In It For You

- Total ownership. Your code decides if we scale or die.
- Zero politics, zero handholding. Just outcomes.
- Massive visibility. If you re valuable, everyone will know it.
- Work with a team that s already shipped to 100M+ people - and is doing it again.

If you ve fought fires in production, debugged chaos at 3 AM, and still wanted more - you re our kind of engineer. Disclaimer: This job posting has been aggregated from external source.
