Hamming AI is seeking a Product Engineer to own the full lifecycle of product features, from concept to iteration, while partnering directly with customers to ensure strong adoption and measurable outcomes. You'll play a central role in shaping the core functionality of our voice-agent QA platform, building reliable, user-focused experiences in a fast-moving startup environment.
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.
What We're Looking For
- 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.
Nice to Have
- 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.
