Responsibilities

  • Design and implement agent execution loops, planning strategies, tool interfaces, verification, and clear system boundaries.
  • Build multi-agent delegation, coordination, context sharing, result synthesis, concurrency handling, cancellation, and stale-result management.
  • Make stateful workflows resilient through checkpoints, recovery strategies, partial-failure handling, and human intervention.
  • Improve retrieval, context construction, persistent state, memory, and reusable skill representation.
  • Build evaluations and experiments, analyze task trajectories, and measure quality, reliability, latency, and cost improvements.
  • Evaluate models and emerging techniques and make informed build-versus-buy and tooling decisions.
  • Set engineering standards, review important design decisions, and maintain ownership of the AI architecture and shipped results.

  • Hands-on experience with browser or computer automation in an agentic system, including state observation, effect verification, and failure recovery.
  • Strong software engineering ability in Python, TypeScript, or a comparable language, including asynchronous services, state machines, persistence, concurrency, retries, and cancellation.
  • Ability to distinguish model decisions from guarantees enforced in code and reason about permissions, untrusted inputs, uncertain outcomes, and human approvals.
  • Ability to design experiments, debug real system behavior, explain measured improvements, and take ownership of ambiguous problems.
  • Useful additional experience includes agent memory and retrieval, skill acquisition, reinforcement learning or post-training, trajectory datasets, sandboxed execution, distributed systems, inference optimization, and multimodal or voice models.
  • No specific degree, publication record, previous employer, or agent framework is required.
