GEICO is transforming how AI is built and deployed across the enterprise. As one of the largest insurers in the United States, we are investing heavily in next-generation AI platforms that empower more than 30,000 associates and enhance experiences for millions of customers. We are looking for a Senior Software Engineer with strong backend engineering experience to help build GEICO's enterprise AI Agent Platform.

The team is building several core systems: an agent harness that runs agentic workflows durably in production, a retrieval‑augmented generation (RAG) platform that grounds agents in enterprise knowledge, an insight engine that turns agent execution data and signals from related systems into live domain knowledge and context for both people and agents, an eval harness that measures agent quality and catches regressions, and a skills marketplace where teams publish and reuse agent capabilities.

Each of them is a distributed systems problem at its core. We care about your experience building durable, scalable systems as well as your experience in AI/ML.

As a Senior Software Engineer on the AI Agent Platform team, you will design, build, and own significant components of the core systems that power use‑case‑agnostic agentic workflows across the enterprise, from claims and underwriting to internal associate tools. You'll work closely with Sr. Staff and Staff engineers who set technical direction. This is platform work: generalized services and capabilities that many teams build on, not a single agent application.

We welcome candidates from application, platform, or infrastructure backgrounds. What matters is that you have designed and built systems that stay correct, available, and operable under real production load, that you've helped run them (on call, incidents, and all), and that you're comfortable working across the full backend stack. Hands‑on experience building GenAI applications or agentic harnesses is a strong plus, and the foundation is solid engineering judgment.
