Senior Software Engineer, AI Agent Platform

GEICO

Why Join GEICO?

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.

The Opportunity

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.

What You Will Do

Own and Collaborate

• Own the design and delivery of significant platform components and features end to end, from technical design and API definition through implementation, rollout, and iteration.
• Write clear design docs, contribute actively to design and code reviews, and make sound tradeoffs within your area of ownership.
• Mentor junior and mid-level engineers, and help raise the engineering bar on the team.
• Collaborate with product managers, data scientists, and consuming teams to understand workflow needs and translate them into platform features.

Build

Depending on your strengths, you'll build and own work in areas such as:

• Agent harness: the durable execution engine for agent workflows, with state management, checkpointing, retries, idempotency, and recovery for long-running, multi-step, tool-calling workflows.
• Agent harness integrations: services, APIs, and integration contracts (including protocols like MCP) that let many teams connect agents to internal services, data sources, and external systems consistently.
• RAG platform: shared ingestion, chunking, embedding, indexing, and retrieval services that ground agents in enterprise documents and data, with access controls, freshness guarantees, and low-latency retrieval at scale.
• Insight engine: pipelines and services that collect data from agent executions and related enterprise systems and turn it into continuously updated domain knowledge and agent context, served to people through dashboards and reports and to agents through retrieval and tool interfaces. Where the RAG platform grounds agents in relatively static documents, the insight engine captures what is changing: emerging patterns, outcomes, and operational signals.
• Eval harness: high-throughput pipelines for running offline and online evaluations, simulating scenarios, capturing execution traces, detecting regressions, and storing large volumes of execution data, as a shared framework every team can use.
• Skills marketplace: a multi-tenant service where teams publish, version, discover, and reuse agent skills and tools, backed by permissions, security review, and governance.
• Reliability, isolation, and cost controls: sandboxing, rate limiting, quotas, SLOs, and capacity planning at enterprise scale.
• Work across the stack as needed, from storage and data modeling to services, deployment infrastructure, and the developer-facing surfaces (SDKs, CLIs, portals) teams use to build on the platform.

Operate

• Own the production health of the components you build: help define SLIs and SLOs, and build the dashboards and alerts that tell the team when something is wrong before users do.
• Build observability in from the start, with metrics, structured logging, and distributed tracing that make failures in the agent harness and in complex, multi-step agent workflows quick to diagnose.
• Design for scale and resilience through load testing, capacity planning, graceful degradation, and failure-mode analysis, so the platform holds up as adoption grows across the enterprise.
• Participate in the on-call rotation, respond to incidents, and contribute to blameless postmortems that result in durable fixes rather than repeat incidents.
• Contribute to operational excellence through runbooks, alert hygiene, and safe deployment practices (canaries, feature flags, rollbacks).

Minimum Qualifications

• 5+ years of professional software engineering experience building and operating production backend systems at scale.
• Experience owning the design and delivery of services or major features end to end.
• Strong proficiency in one or more of Python, Java, Go, or comparable languages.
• Strong distributed systems fundamentals, including concurrency, consistency, fault tolerance, data modeling, API design, and scalability.
• Experience operating production services with CI/CD, automated testing, and Kubernetes or other container platforms.
• Hands-on operational experience supporting production systems, including observability, monitoring and alerting, on-call participation, incident response, and postmortems.
• Experience scaling systems or improving reliability, such as meeting SLOs, performance tuning, capacity planning, or eliminating recurring failure modes.
• Background in application, platform, or infrastructure engineering; all are relevant.

Preferred Qualifications

• Experience with durable execution or workflow orchestration systems (e.g., Temporal, Restate, DBOS, Azure Durable Task, AWS Step Functions) or event-driven architectures (e.g., Kafka).
• Experience building internal developer platforms, multi-tenant services, or SDKs used by many teams.
• Experience building GenAI applications and agentic harnesses, using frontier and open-weight models (e.g., GPT, Claude, Gemini, Llama, Qwen) and frameworks such as LangGraph, Microsoft Agent Framework, OpenAI Agents SDK, or Claude Agent SDK.
• Experience building RAG systems at scale, including ingestion pipelines, hybrid retrieval (dense plus keyword search), reranking, and permission-aware retrieval, using engines such as Azure AI Search, OpenSearch, or Vespa.
• Experience building data pipelines or analytics systems (e.g., streaming ingestion, event processing, knowledge graphs, or feature stores) that turn operational data into insights or context for downstream consumers.
• Experience building evaluation frameworks for LLM or agent systems, or capability ecosystems such as MCP server registries or Agent Skills marketplaces.
• Experience with observability and evaluation tooling such as OpenTelemetry, Prometheus, Grafana, Datadog, Langfuse, LangSmith, Braintrust, or Arize Phoenix.
• Experience with SRE practices such as error budgets, chaos engineering, or game days.
• Experience with cloud platforms such as Azure or AWS, including managed agent services like Microsoft Foundry Agent Service or Amazon Bedrock AgentCore.
• Understanding of AI security and governance, including prompt injection, sandboxing, and supply chain security for third-party tools and skills.

Why This Role Is Unique

• Apply your distributed systems skills to one of the most important new workloads in enterprise software.
• Build the agent harness, RAG platform, insight engine, eval harness, and skills marketplace: shared infrastructure, not a single agent, that every business workflow at GEICO can build on.
• Help build the systems that decide whether GEICO's agents are reliable, measurable, and reusable at scale.
• Build AI capabilities that impact 30,000+ associates and help shape AI experiences used by millions of customers.
• Grow your career alongside senior AI and engineering leaders shaping the next generation of AI at GEICO.
