Company mission
To provide the insurance ecosystem with a comprehensive communication platform.
Role
Who you are
- A genuine curiosity about AI and emerging technologies, paired with the judgment to apply them thoughtfully and responsibly
- Deep AWS expertise: You can architect a multi-tenant platform on AWS without needing to outsource the hard parts. Bedrock, Cognito, IAM, EventBridge, Lambda, DynamoDB or Postgres, plus IaC (CDK or Terraform). Bonus: AgentCore, SageMaker, Workshop Studio
- 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
- Strong product instincts, not just infra: You think about the developer experience of the people consuming your platform. You can design an SDK or a registry schema that other teams actually want to use
- AI-forward: You've shipped real LLM-backed systems in production — not just prototypes — and have opinions about token cost, latency, evaluation, observability, and where determinism matters vs. where it doesn't
- MCP / agentic systems literacy: Familiarity with Model Context Protocol or comparable agent-tool patterns. You don't have to have shipped an MCP server, but you should be able to talk credibly about why MCP exists and what its security boundaries are
- Excellent communicator: You can present platform work to engineers, executives, and customers, and write docs people actually read. This role only succeeds if the rest of the company knows what's available
- Architectural integrity over framework hype: You'd rather build the right primitive on AWS than reach for a "magical" higher-level abstraction. You can write Python, TypeScript, or Go fluently — the language matters less than the systems thinking
What the job involves
- 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. This is the engineer who builds the plumbing of our internal agentic workforce: the AWS hosting layer, the Cognito-backed identity model, the Accountability Registry that says who built what, the Agent Registry that governs who can act, and the Tool Catalog that lets our teams compose new capabilities safely
- 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
- If you love AWS Bedrock at the depth where Cognito, IAM, and CDK meet, want to define how an entire company governs agents, and have the communication chops to evangelize a platform internally, this is the role for you. 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
- Build the AI Operations platform on AWS: Own the hosting, deployment, and infra-as-code layer for every internal agent and tool we run. Bedrock for models, Cognito for auth, CDK or Terraform for everything else. No third-party platforms — we are AWS-only by design
- 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). These are the spine of agentic governance at Hi Marley
- 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
- Evangelize the platform internally: Lunch-and-learns, internal docs, demo droplets, and "office hours" so other teams know what's available and how to use it. Communication and product instinct are as load-bearing as the AWS depth
- Use AI in your daily flow: Cursor, Claude Code, agentic coding tools — your default question is "could an agent do this?" before you write the code yourself
Our take
The insurance industry can be notoriously frustrating for policyholders during the claims process, with a reported 40% of people considering a switch of insurers following a claim. This is the outcome that Hi Marley wants to help carriers avoid.
The company uses an AI-enabled communication platform designed to allow insurance carriers and their partners to talk to policyholders in real time via simple text messaging. This ultimately gives carriers more opportunities to satisfy and retain their customers.
Hi Marley has enjoyed rapid growth in recent years, with a quadrupling of its user base. It has also more than doubled the number of carriers using its platform, which now includes the likes of American Family, MetLife, Auto-Owners, Erie, and MAPFRE. Improvements such as the addition of a suite of collaborative tools to its platform seem likely to help it maintain its edge in the market.
