Job Summary
Design and ship AI-first platform systems for agent orchestration, retrieval, and structured output within a high-volume home inspection SaaS product. Operate non-deterministic systems using tracing, evals, and model routing while managing ECS container operations, AWS serverless pipelines, and production PHP codebases. Drive database performance at scale across MySQL and Aurora, executing zero-downtime migrations and query optimization. Lead code reviews, mentorship, and incident response as part of the on-call rotation. This role offers unusual latitude to define AI architecture at Porch Group, leveraging our data from 30,000 key home-buying transaction partners.
Required Qualifications
- 10+ years building and running production software, with real ownership of systems at scale
- Demonstrated, hands-on experience shipping LLM-backed features — not just API calls, but agent orchestration, RAG, evaluation, and the operational discipline to keep them working
- Strong PHP (8.x) skills in a mature, high-traffic codebase
- Deep AWS architecture experience with hands-on ECS operations, infrastructure as code (Terraform or CDK), and CI/CD
- Expert-level relational database skills with MySQL and/or Aurora — able to read an execution plan and act on it
- Strong fundamentals in distributed systems, API design, observability, and application security
- Clear written communication and sound judgment about tradeoffs, especially where AI is the wrong tool for the job
- Must be able to work in a fully remote position within the United States
- Must be willing to work in a location outside of Alaska, Delaware, Hawaii, Mississippi, Nebraska, Montana, New Hampshire, West Virginia, or the District of Columbia
Desired Qualifications
- Nice to have: Go, MCP or comparable agent-tooling standards, vector search and embedding pipelines, Kubernetes, document and image extraction pipelines, or real estate/proptech/field-services domain experience
