About Hamming AI
Hamming automates QA for voice AI agents. Everyone is building voice agents. We secure them. In fact, we invented this category. With one click,
thousands of our agents call our customers’ agents
across accents, background noise, and personalities—then we generate
crisp bug reports
and production-grade analytics. Reliability is the moat in voice AI, and that’s our whole job.
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.

What you’ll do
Own product features end-to-end : spec → prototype → ship → iterate, across frontend and backend.
Work closely with customers:
onboard new accounts, run weekly check-ins, and act as a high-agency partner to drive adoption and outcomes.
Build core customer workflows
for voice-agent QA: test creation, scenario management, evaluation results, analytics, debugging, and triage.
Turn messy, high-dimensional data (calls, transcripts, tool events, traces, eval outputs) into
product experiences that are obvious and actionable.
Partner with customers
to understand their reliability pain, then translate it into shipped product with measurable outcomes.
Tighten the product loop:
instrumentation, funnels, and feedback so we know what’s working and what’s not.
Maintain high engineering velocity while keeping craftsmanship : clean APIs, strong abstractions, and excellent UI polish.
You might be a fit if you
Have 3+ years building customer-facing products
in a high-velocity environment (startup experience a plus).
Are fluent in TypeScript
and comfortable across the stack (React/Next.js + Node services).
Ship quickly but with discipline:
you write clear code, strong tests where it matters, and avoid accidental complexity.
Have strong product instincts:
you can simplify complex workflows into crisp UX and make good tradeoffs under ambiguity.
Love talking to users,
diagnosing friction, and iterating until a feature feels “done.”
Care about reliability:
you build with observability, failure modes, and data correctness in mind.
Communicate clearly:
written specs, crisp PRs, and decisions that scale across a fast-moving team.
Bonus
Experience building analytics-heavy products
(dashboards, event pipelines, debugging tools).
Familiarity with LLM apps , evals, tool calling, or prompt/guardrail systems.
Experience with real-time systems,
telecom/voice, or high-concurrency workflows.
Strong UI craft:
interaction design, information architecture, and performance tuning.
Interesting problems you’ll touch
Debugging workflows for voice agents:
call timelines, transcripts, tool calls, traces, and “what changed?” diffs.
Test authoring that scales:
scenario libraries, parameterization, coverage, and regression packs.
Evaluation UX:
turning model-graded / heuristic / human feedback into trustworthy signals and action items.
Analytics that matter:
reliability metrics customers can run their business on.
Enterprise readiness in-product:
RBAC, audit trails, data retention, and environment/region controls.
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

If you want to build
the product layer for reliable Voice AI , let’s talk.
Send a short note (links to work > resumes) to
careers@hamming.ai
and tell us about a product you shipped end-to-end: what you built, where it was painful, what tradeoffs you made, and how you knew it worked.
