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. —

Sumanyu (CEO)

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

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

1.

Have 3+ years building customer-facing products

in a high-velocity environment (startup experience a plus). 2.

Are fluent in TypeScript

and comfortable across the stack (React/Next.js + Node services). 3.

Ship quickly but with discipline

you write clear code, strong tests where it matters, and avoid accidental complexity. 4.

Have strong product instincts

you can simplify complex workflows into crisp UX and make good tradeoffs under ambiguity. 5.

Love talking to users,

diagnosing friction, and iterating until a feature feels “done.” 6.

Care about reliability

you build with observability, failure modes, and data correctness in mind. 7.

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. ##
