Hybrid AI Technical Lead — Build Open-Weight Models

EverQuote Pro; Cambridge (MA); Hybrid; USD 203,000 - 239,000; Full time

Job summary

EverQuote is looking for an AI Technical Lead in Cambridge, MA, to own the end‑to‑end technical architecture of a new insurance marketplace used by AI agents. This hands‑on senior role will shape model hosting, MCP server, data tooling, and integration patterns for scalable, cost‑efficient operation.

You will lead design decisions, tune models, stand up serving infra, and implement robust testing, guardrails, and monitoring.

Qualifications

• 8+ years in engineering with senior or lead ownership of complex technical systems, including hands‑on work in ML/LLMs.
• Track record of leading large, ambitious projects with a small team and delivering them.
• Hands‑on fine‑tuning and deployment of open‑weight or open‑source models, with real production experience.
• Enterprise design and architecture experience for complex, high‑reliability systems.

Responsibilities

• Own the architecture: decide where the agent’s reasoning runs, which models we use, how they are packaged, and how AI platforms connect to us, and back those calls with testing.
• Build and tune the models: fine‑tune open‑weight models for our use, and decide when tuning, retrieval, or prompting is the right tool.
• Stand up the serving and infrastructure: deploy the agent and MCP server so they are reliable, fast, and affordable to run, with versioning and a way to roll back.
• Build the testing into the system: programmatic eval sets, guardrails, and monitoring for quality, drift, cost, and speed, so we catch problems before agents do.
• Design the data model and tools with the AI product lead: the request and response payloads, the reasoning we expose, and the trust signals.
• Set the engineering patterns and standards the team builds on, and keep the code and architecture documented.
• Keep cost and speed honest: watch what inference costs, and make the trade‑offs that keep it sustainable as volume grows.
• Work in the open. Help publish our code, architecture, and findings.
• Mentor the engineers on the team and give leadership clear, regular visibility into technical progress and risks.
