Tech Lead

Location: Remote (North America) or Austin, TX Employment Type: Full-time (no contractors) Department: Engineering   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.   Devin Case Study https://devin.ai/customers/hamming Ranked #1 Eng team https://www.linkedin.com/posts/andrew-d-churchill_sumanyu-ceo-at-hamming-ai-had-20x-the-output-activity-7354564854029901824-jSDP?utm_source=share&utm_medium=member_desktop&rcm=ACoAAAh-eI0Bl3EbQhXGlnjcZ4TbyeByvoh32hg OpenAI Dev Day 100billion token list https://www.linkedin.com/posts/sumanyusharma_openaidevday-activity-7381718141455859712-OPhA?utm_source=share&utm_medium=member_desktop&rcm=ACoAAAh-eI0Bl3EbQhXGlnjcZ4TbyeByvoh32hg   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.
