Principal AI Engineer -Enfi
unusual · Boston, Massachusetts
Open. First seen 14 March 2026.
Description
Overview We’re looking for a Senior Principal AI Engineer to provide hands-on technical leadership across complex, production-grade AI systems. This role is for a builder-architect—someone who has repeatedly taken AI systems from idea to production, understands where they fail at scale, and knows how to unblock teams to move faster without sacrificing outcomes. This is not a pure strategy or people-management role.
It is a deeply technical builder role with organizational impact. You will define technical direction by writing code, designing systems, and helping the organization stay in builder mode as complexity and scale increase.

About Us
We are an AI-first company, and we mean that literally. AI is not a feature we bolt on. It’s not a marketing layer.
It’s not a roadmap experiment. It is the foundation of how we design, build, and operate. We are building systems where machines do what machines do best: pattern recognition, synthesis, analysis at scale.
As well as what humans do what humans do best: judgment, context, trust, and accountability. That means rethinking workflows from the ground up. Not “how do we add AI to this process?” but “how should this process exist in a machine-augmented world?” We care deeply about shipping real systems that work in production.
In regulated environments. With real customers. At scale.
If you’re excited to help invent the next way software is built and deployed, and to do it alongside a team of deeply pragmatic, AI-obsessed builders, we’d love to talk.
