About Hamming AI

Hamming automates QA for voice AI agents. Everyone is building voice agents. We secure fact we invented this category. With one click thousands of our agents call our customers agents across accents background noise and personalitiesthen we generate crisp bug reports and production-grade analytics. Reliability is the moat in voice AI and thats our whole job.

We are one of the fastest engineering teams in the world. We prod deploy 4x / day.

Im looking for someone who can own reliability and scale across our LLM-enabled platformshipping precise outcome-driven improvements to high-availability systems.

Why this role matters

Were moving fast shipping constantly and need a tech lead who can guide the team without slowing it down .

This isnt a people-manager role hidden behind meetings. Youll lead a team of five engineers make architecture calls mentor others and still ship meaningful code every week . Youll be in the middle of everything - from scaling our evaluation engine to making sure customers love the product.

What youll own

Technical direction across the stack - backend frontend and infra. Youll decide whats good enough today and what deserves to be rebuilt.

Team leadership : unblock engineers set clear priorities run lightweight design reviews and keep the team aligned without red tape.

System reliability : make sure our platform stays fast observable and stable while traffic grows 100x.

Hands-on delivery : contribute to key projects weekly from new product experiments to hardening real-time systems.

Cross-functional glue : keep product and operations connected so decisions flow and context isnt lost.

What youll do day to day

Write code (TypeScript Python or both) alongside your team.

Review architecture and PRs - guide decisions without micromanaging.

Help define sprint priorities and keep roadmaps tight and realistic.

Pair with engineers when things break - not just to fix them but to make sure they dont break again.

Run post-mortems that actually lead to better systems not longer docs.

Evaluate new tech (LLMs infra tools observability stacks) and decide whats worth bringing in.

You might be a fit if you

Have 6 - 10 years leading 3 - 6 engineer pods in high-availability high-frequency deploy shops.

Built and operated realtime / distributed systems (workflow engines WebRTC / telephony large fan-out queues).

Still enjoy shipping code and debugging hairy issues yourself.

Have strong fundamentals across backend infra and architecture and can also talk product tradeoffs fluently.

Can move comfortably between TypeScript / Python and cloud infra (AWS Terraform Kubernetes) .

Understand how to design LLM-powered systems that are testable measurable and resilient.

Communicate clearly - direct concise and respectful. You default to writing things down.

Care about outcomes more than process.

Bonus points if youve :

Built AI products (especially voice or real-time systems).

Operated at an early-stage startup before - and liked it.

Have an instinct for how to turn chaos into repeatable systems.

How we work

Outcomes over output : we adjust roadmaps when new data lands.

Demo early and document decisions so context moves fast.

Own incidents : lead the investigation write crisp notes land durable fixes.

Direct candid respectful communication keeps remote teammates in lockstep with Austin HQ.
