Senior Software Engineer

• Huge market, weak competition: Billions of offline conversations happen daily. No one else is solving this for real enterprise.
• Large enterprise customers: We're already working with multi-billion dollar manufacturers, retailers, and logistics companies.
• Strong founding team: Backgrounds from Harvard, Princeton, Meta, Insight Partners, IBM. We know how to listen, build, sell, ship, scale- then iterate and accelerate.
• Real upside: Already backed by the best with $6M+ from 645 Ventures, NextPlay Ventures (Jeff Weiner), Wisdom, and angels, but early enough for founding team members to see generational outcomes from equity.
• Product that works: Customers see immediate ROI. Enterprise deals close fast.

Mostly importantly, join for the team. We're A+ players who live our values:

• Own the outcome: From first idea to customer impact, see it through. No hand-offs, no excuses.
• Real problems only: Find energy in work that actually matters, not in building features that sound cool but solve nothing.
• Intellectual honesty: Admit what isn't known, ask uncomfortable questions, and challenge assumptions without fear.
• Clarity through chaos: Thrive in 0-to-1, high-intensity environments. Move fast but think clearly, turn confusion into direction, ship quality under pressure.
• Empathy above all: Obsess over customer problems and think deeply about user needs before making any decision.

Compensation Range: $170K - $220K

Do you have experience in Startup experience?, * 5+ years shipping production software, including time as an early engineer at a seed/Series A startup

• Full-stack generalist who owns features end-to-end with sharp product judgment - knows what to build, what to cut, when to push back
• Ships predictably and communicates clearly; credible with an enterprise VP of Ops on a customer call and async with a remote CTO
• Production experience in at least one of voice/audio, LLM apps, or data/insights pipelines (Umi is all three)
• Fluent in Python/FastAPI + TypeScript/React; moves across frontend, backend, and infra in a single PR
• Has shipped against flaky third-party APIs under latency/reliability pressure (telephony, real-time audio, payments, etc.)
• Working knowledge of LLM app development: prompts, structured output, retrieval, evals, and non-deterministic systems that hold up in prod
• AWS or GCP with multi-tenant SaaS security instincts (data isolation, PII, SOC 2)
• Excited to be a foundational hire building AI for frontline enterprise

Nice-to-haves

• Staff/tech-lead IC ready to grow into eng lead within ~12 months
• Voice agent stack (LiveKit, Pipecat, Vapi, Retell, or custom on Twilio/Deepgram/ElevenLabs) + speech fundamentals (ASR, TTS, diarization, VAD)
• Production agentic LLM workflows: tool use, multi-step, eval-driven
