Staff AI Platform / Agent Infrastructure Engineer at seed-stage fintech startup

About the role

Lead the architectural shift toward AI-native engineering by building the core harness for autonomous agents. You will own the local development environment, asynchronous execution systems, and evaluation suites that allow AI agents to ship production-grade code safely. This role bridges platform engineering with non-deterministic system observability at a well-funded fintech startup.

Why this role is remarkable

• Architect a first-of-its-kind AI engineering harness where agents operate as first-class developers.
• Join a well-funded seed-stage startup backed by top-tier VCs with significant real-world customer traction.
• Define the new category of AI infrastructure engineering, moving beyond traditional DevOps into non-deterministic system observability.

Responsibilities

• Design and ship a local development environment and async execution infrastructure for advanced agent orchestration.
• Build comprehensive evaluation suites and automated review pipelines to ensure agent-generated code meets production-grade standards.
• Develop agent-aware CI/CD pipelines and observability tools to maintain high-stakes data accuracy and SOC 2 audit trails.

Requirements

• 5+ years of infrastructure or platform engineering experience building production tools used by other engineers.
• Deep expertise in AWS services and Infrastructure as Code fluency using tools like Terraform or Pulumi.
• Proven experience building evaluation harnesses or test infrastructure specifically designed for non-deterministic systems or LLM outputs.
