Senior Platform Engineer - AI Platform

Job Title: Senior Platform Engineer - AI Platform

Location: United States

Workplace Type: Remote

Job Summary

The future is bright for the Porch Group, and we'd love for you to be a part of it as our Senior Platform Engineer - AI Platform.

ISN is hiring a Senior Platform Engineer to lead AI-first platform work at the intersection of agentic systems and production infrastructure. You'll design and ship the systems that let agents and LLMs do real work inside a high-volume product - spanning scheduling, report intake, customer communication, billing workflows, and data extraction. You'll also own the foundation underneath it: our PHP application, AWS/ECS infrastructure, and MySQL/Aurora data layer. This role offers unusual latitude to define how AI works at ISN, backed by the scale and stability of Porch Group and the data of a category-leading home inspection software platform.

What You Will Do As A Senior Platform Engineer - AI Platform

• Build AI features end to end - retrieval, context engineering, structured output, tool/function calling, and evaluation harnesses that measure whether a change actually made things better
• Design and operate agent orchestration systems - multi-agent and multi-step workflows including task decomposition, tool routing, state and memory, retries and fallbacks, human-in-the-loop checkpoints, and guardrails against failure modes that don't look like exceptions
• Operate non-deterministic systems responsibly - tracing, evals in CI, prompt and model versioning, token and latency budgets, model routing, and cost controls
• Own ECS container platform operations - service definitions, task sizing, autoscaling, blue/green deploys, and orchestration for both long-running services and async workers
• Architect AWS infrastructure - event-driven and serverless pipelines (Lambda, SQS/SNS/EventBridge), IAM and network design, all managed as infrastructure as code
• Build and extend services in our production PHP codebase, integrating AI capability into existing product surfaces without destabilizing them
• Drive database performance at scale - schema design, indexing, replication and read scaling, zero-downtime migrations, and query performance work across MySQL and Aurora
• Raise the bar across the team through code review, design docs, mentorship, incident response, and on-call participation

What You Will Bring As A Senior Platform Engineer - AI Platform

• 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
• 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

The application window for this position is anticipated to close in 2 weeks (10 business days) from 11/9/2026. Please know this may change based on business and interviewing needs.
