Staff/Senior Software Engineer, Agent Engineering (Helios)

Expected areas of expertise:

• Production orchestration for stateful, long-running, and multi-agent workflows.


• Tool and action infrastructure with strong contracts, permissions, and approval boundaries.


• Retrieval, context engineering, evidence management, and persistent agent memory.


• Model-runtime engineering across providers, latency profiles, and deployment environments.


• Evaluation, tracing, security, and operational control of nondeterministic systems.

• Own Proxi’s agent runtime and strengthen foundations for building new agent-driven products.


• Build the systems that allow agents to own long-running work from assignment through completion. Agent activity should remain visible, steerable, and connected to the relevant project, people, evidence, deadlines, and deliverables in Action Rail.


• Build the tool and action framework agents use to interact with internal systems and external services safely.


• Connect agents to Proxi’s retrieval and knowledge systems so reasoning, memory, citations, and generated artifacts remain grounded in authoritative evidence.


• Improve the evaluation and release discipline for agent behavior, traces and simulations to improve quality while controlling latency, cost, and risk.

• Experience deploying agent systems in government, defense, legal, healthcare, or other regulated environments.


• Familiarity with policy and legal research where temporal accuracy, provenance, and citation precision are essential.


• Experience operating self-hosted or multi-provider inference in restricted environments.


• Experience building agents that create durable artifacts or perform permissioned actions on a user’s behalf.
