Job summary

Hone in San Francisco is building engines that run across a company’s systems. You’ll own the surfaces where people set up, supervise and calibrate engines, end to end from schema to UI: onboarding, real-time activity, reviews, routines, memory and permissions.

We’re seeking engineers with 2+ years of full‑stack experience, who have shipped products to real users and who can pair Python, TypeScript and React with thoughtful product and design judgment.

Qualifications

• 2+ years of engineering experience or equivalent depth from open source or your own projects
• Time at a fast-growing startup
• You've built products from scratch and shipped them to real users
• You've owned polished features end to end, from backend to UI
• Strong product and design judgment: what to cut, what to polish, when to ship
• Strong full-stack fundamentals: Python, TypeScript, React, Postgres, real-time interfaces, debugging unfamiliar code
• You use coding agents every day and still understand every line you ship

Responsibilities

• Own surfaces where people set up, supervise and calibrate engines end to end, from schema to UI.
• Onboard, real-time activity, review and approvals, routines, memory, permissions, and the tools where people already work.
• Interfaces that make a long-running agent swarm easy to understand: what it's doing, why, and what it plans to try next.
• Multiplayer interaction with one persistent engine: shared and personal memory, conflicting feedback, per-person permissions.
• Engine surfaces in chat and email.
