The posting

Tech Lead (IC) – Architecting the Next Billion-User Systems

About Us

We’re Primetrace Technologies - the team behind:

Crafto – 100M+ downloads- https://crafto.app/

Kutumb – 100M+ downloads- https://kutumbapp.com/

We build products used by tens of millions. And we don’t have the luxury of things “just working.” They have to scale, survive, and stay fast — always.

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 D

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 good, 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.

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
