ABOUT HAMMING AI

Hamming builds three products for voice and chat AI agents: testing/simulation to validate behavior before launch; red-teaming to probe for prompt injection, jailbreaks, PII leakage, and policy violations; and production monitoring/observability to detect failures in live conversations and turn them into regression tests.

We are one of the fastest engineering teams in the world. We prod deploy 4x / day. I’m looking for someone who can own reliability and scale across our LLM-enabled platform—shipping precise, outcome-driven improvements to high-availability systems.

— Sumanyu (CEO) Previously: grew Citizen 4× and scaled an AI sales program to $100Ms/yr at Tesla.

WHY THIS ROLE MATTERS

We’re moving fast, shipping constantly, and need a tech lead who can guide the team without slowing it down.

This isn’t a people-manager role hidden behind meetings. You’ll lead a team of five engineers, make architecture calls, mentor others, and still ship meaningful code every week. You’ll be in the middle of everything - from scaling our evaluation engine to making sure customers love the product.

WHAT YOU’LL OWN

- Technical direction across the stack - backend, frontend, and infra. You’ll decide what’s “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 isn’t lost.

WHAT YOU’LL 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 don’t break again.

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

- Evaluate new tech (LLMs, infra tools, observability stacks) and decide what’s 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/Node.js, 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 you’ve:

- 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.

OUR STACK

- App: Next.js, TypeScript, Tailwind

- AI: OpenAI, Anthropic, STT/TTS providers

- Realtime/Orchestration: LiveKit, Pipecat/Daily, Temporal

- Infra/DB: AWS, k8s, PostgreSQL, Redis, Terraform

- Observability: OpenTelemetry, SigNoz

APPLY

If you want to lead a small, senior team that’s building the backbone of reliable voice AI, we’d love to talk.

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.
