About the role
- Artisan · Full-time · In person in San Francisco Base salary: $250,000-$325,000 USD annually.
- We're keeping the product details private ahead of launch, but we can tell you this: the technical problems are substantial, the scope for invention is real, and this hire will shape the core technology.
- You'll work across agent behavior, complex multi-agent systems, tool use, context, and evaluation, taking promising ideas through to dependable production software.
Responsibilities
- Artisan builds AI employees that take on real work.
- We're looking for a hands-on technical lead to design and build the underlying AI architecture.
- Agent architecture and behavior. Design and implement agent execution loops, planning strategies, tool interfaces, and verification. Turn ambiguous technical requirements into clear system boundaries and working code.
- Multi-agent systems. Build delegation, coordination, context sharing, and result synthesis. Handle concurrent work, conflicting updates, cancellation, and stale results. Establish when a multi-agent approach improves on a simpler baseline.
- Reliable execution. Make complex, stateful workflows resilient to interruptions and partial failures. Build checkpoints, recovery strategies, and appropriate human intervention into the architecture.
- Context, memory, and reusable methods. Improve retrieval, context construction, persistent state, and skill representation. Investigate how systems can use feedback and prior experience to perform better without introducing regressions.

- You have hands-on experience with browser or computer automation in an agentic system, including observing state, verifying effects, and recovering when an interface or execution path fails.
- You are an excellent software engineer in Python, TypeScript, or a comparable language.
- You are comfortable with asynchronous services, state machines, persistence, concurrency, retries, and cancellation.
- You know which decisions belong to a model and which guarantees must be enforced in code.
- You can reason carefully about permissions, untrusted inputs, uncertain external outcomes, and human approvals.
- You can take technical ownership of an unclear problem, work effectively with other engineers, and ship with urgency and care.
- There is no required degree, publication record, previous employer, or agent framework.
