About The Position

We unlock ground truth for the enterprises that power the global economy. Billions of critical conversations happen every day in retail, hospitality, food service, logistics, and beyond — with customers and employees. Historically, these insights disappear the moment they're spoken. Arbor turns in-person conversations into executive-grade strategic intelligence. We're signing real enterprise contracts in industries that power the global economy. The opportunity is massive, the problems are unsolved, and we need product-obsessed builders to join on our journey.

Requirements

• 5+ years shipping production software, including time as an early engineer at a seed/Series A startup
• Full-stack generalist
• Production experience in at least one of voice/audio, LLM apps, or data/insights pipelines
• Fluent in Python/FastAPI + TypeScript/React
• 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)

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
• Data/analytics depth: warehouse modeling, DBT, owning an insights pipeline
• On-call comfort on a small team — has been the person paged

Responsibilities

• Own features end-to-end with sharp product judgment — knows what to build, what to cut, when to push back
• Ship predictably and communicate clearly; credible with an enterprise VP of Ops on a customer call and async with a remote CTO
• Move across frontend, backend, and infra in a single PR
• Ship against flaky third-party APIs under latency/reliability pressure (telephony, real-time audio, payments, etc.)
• Build foundational AI for frontline enterprise

Benefits

• 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.
