Job summary

Porch Group is seeking a Senior Platform Engineer to lead AI-first platform work at the intersection of agentic systems and production infrastructure. You will own the PHP application, AWS/ECS, and MySQL/Aurora data layer while shipping end-to-end AI features across scheduling, billing, and data extraction.

Ideal candidates have 10+ years building production software, deep PHP/8.x expertise, and hands-on experience with LLM-backed systems.

Qualifications

• 10+ years building and running production software at scale.
• Hands-on experience shipping LLM-backed features, including agent orchestration and evaluation.
• Strong PHP (8.x) skills in a high-traffic codebase.
• Deep AWS architecture with ECS, infrastructure as code (Terraform or CDK), and CI/CD.
• Expert relational database skills with MySQL and/or Aurora.
• Strong fundamentals in distributed systems, API design, observability, and application security.
• Clear written communication and sound judgment about AI tradeoffs.
• Nice to have: Go, MCP or comparable agent-tooling standards, vector search/embedding pipelines, Kubernetes, document and image extraction pipelines, or real estate/proptech/domain experience.

Responsibilities

• Build AI features end to end — retrieval, context engineering, structured output, tool/function calling, and evaluation harnesses.
• Design and operate agent orchestration systems — multi-agent and multi-step workflows with task decomposition, tool routing, state and memory, retries and fallbacks, human-in-the-loop checkpoints, and guardrails.
• 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 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 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.

Job description

Senior Platform Engineer - AI Platform

Location: United States (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

• 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

• 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

What You Will Get

• $168,800 – $236,300 annually
• Please know your actual pay at Porch will reflect a number of factors among which are your work experience and skillsets, job‑related knowledge, alignment with market and our Porch employees, as well as your geographic location.
• Additionally, you will be eligible to receive long‑term incentive awards, subject to program guidelines and approvals.
• Our benefits package will provide you with comprehensive coverage for your health, life, and financial wellbeing.
• Our traditional healthcare benefits include three (3) Medical plan options, two (2) Dental plan options, and a Vision plan from which to choose.
• Critical Illness, Hospital Indemnity and Accident plans are offered on a voluntary basis.
• We offer pre‑tax savings options including a partially employer funded Health Savings Account and employee Flexible Savings Accounts including healthcare, dependent care, and transportation savings options.
• We provide company paid Basic Life and AD&D, Short and Long‑Term Disability benefits.
• We also offer Voluntary Life and AD&D plans.
• Both traditional and Roth 401(k) plans are available with a discretionary employer match.
• Supportlinc is part of our employer paid wellbeing program and provides employees and their families access to on demand guided meditation and mindfulness exercises, mental health coaching, clinical care and online access to confidential resources including will preparation.
• LifeBalance is a free resource to employees and their families for year‑round discounts on things like gym memberships, travel, appliances, movies, pet insurance and more.
• Our wellness programs include flexible paid vacation, company‑paid holidays of typically nine per year, paid sick time, paid parental leave, identity theft program, travel assistance, and fitness and other discounts programs.
