Senior Agent Systems Engineer

Acceler8 Talent; San Francisco (CA); On-site; USD 150,000 - 210,000; Full time

Job summary

A tech recruiting firm in San Francisco is seeking a candidate to build robust agent systems using cutting-edge frameworks. The role involves designing workflows with complex logic and rigorous validation while having a significant influence within a technical environment. Applicants should have strong experience in systems, with a focus on reliable production capabilities and reasoning about edge cases. This opportunity promises high ownership and creative problem solving in a collaborative setting.

Qualifications

• Strong experience building agent systems, LLM tool-calling pipelines, or orchestration frameworks.
• Deep intuition for schemas, action abstractions, and state representation.
• Ability to reason rigorously about system-level failure modes and edge cases.

Responsibilities

• Build agent planners, tool-call flows, and structured state machines.
• Design schemas, action adapters, and cross-tool interfaces.
• Implement robust execution logic: retries, rollbacks, timeouts.
• Design agent workflows with clear validation, stopping criteria, and failure handling.

Job description

What You’ll Do

• Build agent planners, tool-call flows, and structured state machines using LangGraph or similar frameworks
• Design schemas, action adapters, and cross-tool interfaces that enable deterministic, traceable LLM tool execution
• Implement robust execution logic: retries, rollbacks, timeouts, checkpointing, and replay mechanisms
• Design agent workflows with clear validation, stopping criteria, and failure handling

What We’re Looking For

• Strong experience building agent systems, LLM tool-calling pipelines, or orchestration frameworks
• Deep intuition for schemas, action abstractions, state representation, and reproducibility
• Ability to reason rigorously about system-level failure modes, edge cases, and safe tool interaction

Why This Role

• Build agent systems that operate reliably in production, not just prototypes
• Work on complex, high-impact engineering workflows with real constraints
• High ownership and influence in a deeply technical environment

💫 Apply if you want to build agent systems that actually work - deterministically, safely, and at scale.
