About this role

# 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.

Must-haves

• 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

• 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

• Data/analytics depth: warehouse modeling, DBT, owning an insights pipeline
• On-call comfort on a s...
