About the role

Insurance touches people during some of the most challenging moments in their lives.
If you believe insurance can combine operational excellence and automation with a human touch, we'd love to meet you.
Bedrock for models, Cognito for auth, CDK or Terraform for everything else.

Responsibilities

Build the AI Operations platform on AWS: Own the hosting, deployment, and infra-as-code layer for every internal agent and tool we run.
Architect the registries and catalogs: Design and build the Accountability Registry (people, ownership, roles), the Agent Registry (identity, permissions, data scope, audit trail), and the Tool & App Catalog (discover, register, approve).
Solve the identity-inheritance problem: An agent acts with the inherited permissions of the human who invoked it. You'll design and ship the patterns - Cognito + IAM + scoped tokens - that make this real, deterministic, and auditable.
Build the developer experience for internal agent builders: Templates, SDK helpers, deploy paths, observability, cost tracking. Make it so that every Hi Marley team can ship their own agent without reinventing security or hosting.
Partner on security tooling with our Compliance & IT lead: Implement the scans, audits, MCP governance hooks, and DLP signals that the AI Security Ops role will use. You build the rails
they build the gatekeeper.
Identity & authorization fluency: You've built systems where authorization is the architecture, not bolted on. OAuth 2.1, scoped tokens, role inheritance, least-privilege design - these are second-nature to you.

What We're Looking For:
Hi Marley is on a mission to transform how the P&C industry communicates, making those moments faster, easier, and more empathetic for carriers and the customers they serve.
As we continue to grow, we're looking for a Principal AI Platform Engineer to be a foundational hire on our new AI Operations team.
You'll partner with the CTO and a UX-focused builder to make Hi Marley an AI-native company from the inside - and you'll do it on a strict AWS stack because our customers are insurance carriers who need real auditability, not a wrapper.
Teamwork and shared enthusiasm are a core part of our culture, which is why this role involves joining us in the Boston office for 2-3 days each week.
