About the job
Designs and builds the core AI architecture for an agentic product, from agent behavior and multi-agent coordination to evaluation and reliable production execution.
What you'll do
- Design agent execution, planning, tool use, verification, context, and multi-agent coordination.
- Build resilient stateful workflows, evaluations, and experiments; use results to improve quality, reliability, latency, and cost.
- Own AI architecture and technical standards, make model and tooling decisions, and work with product and infrastructure engineers to ship production services.
What they ask for
- Personally built and shipped a substantial agentic system, through production use or rigorous, reproducible open-source work.
- Deep practical experience with LLM tool use, planning, context engineering, evaluations, and multi-agent coordination or substantial parallel agent/tool execution.
- Hands-on experience with browser or computer automation in an agentic system, including state observation, effect verification, and failure recovery.
- Strong software engineering in Python, TypeScript, or a comparable language; comfortable with asynchronous services, state machines, persistence, concurrency, retries, and cancellation.
Nice to have
- Experience in agent memory and retrieval, skill acquisition, reinforcement learning or post-training, trajectory datasets, sandboxed execution, distributed systems, inference optimization, or multimodal and voice models.
