About Sable Sable built Aidan, the first AI employee who can lead customer calls using realtime voice, vision, and browser use. Aidan runs a live, two-way conversation inside a real product environment, clicking through the product like a human, watching the user's screen, and adapting the journey on the fly. Every conversation feeds a self-improving context graph we call the Brain, so Aidan gets smarter with each call. The role You own a customer end to end from the engineering side. You join calls with customers, watch where Aidan could improve inside their product, and find the technical breakthroughs: sometimes in the customer's configuration, sometimes in the tooling, and sometimes in the agent itself. You work in a pair with a Deployment Strategist who owns the customer's context and journeys; you own everything that needs code. When the fix belongs in the core agent, you bring the agent team a reproduced case and a proposed change, not a vague report. What you'll do • Be the engineer assigned to a set of accounts, from first scoping call to live implementation • Build the tooling that makes deployments faster: replay, evaluation, configuration, integrations into the customer's stack • Coordinate development with the agent team. • Turn what you learn on each account into playbooks so the next deployment needs less of you Who you are • Strong software engineer, comfortable across backend, browser automation, and LLM-based systems • You like working directly with customers and leading technical discussions when necessary • You have shipped at a startup or as a founder, or have been in a forward deployed or solutions role • Bonus: hands-on agent, prompt, or evaluation work; experience with voice or realtime systems
