Description

Description

Working as an Applied AI Engineer at Michelin on topics of Spec-Driven Development, harness engineering, and generative artificial intelligence exploration. Contributing to the delivery of fullstack features using a spec-first approach, from specification to production.

The scope covers context engineering, which involves structuring and enriching technical and business specifications to guide coding agents, as well as loop engineering to control and stabilize iterative agent loops, such as Copilot or Codex, until the produced code is accepted. Also working on harness engineering for the setup and maintenance of tools, tests, and quality gates surrounding these loops, including unit, integration, and end-to-end tests.

Implementing an approach similar to Jira-driven development, with structured tracking of specs, stories, and BDD scenarios directly linked to the backlog, in partnership with the architect.

Contributing to continuous process improvement, enriching reusable spec libraries, prompt patterns, and velocity and quality metrics.
