Applied AI Engineer, Internal Tooling - New York
Automattic Remote
Location: NYC NoHo Office (5 days a week) About This Opportunity Build the AI tools that Automattic uses internally. Maintain and extend LibreChat, our self-hosted AI interface. Create lightweight integrations and automations that make teams more productive. Help 1,500 people work better with AI. This isn’t about building consumer products or shipping to millions of users.

AI Adoption Manager - New York
Automattic New York, NY, USA
Location: NYC NoHo Office (5 days a week) About This Opportunity Help 1,500 people at Automattic use AI tools exceptionally well. Not just “here’s how to use Claude”, but “here’s how to build custom agents for your workflow,” “here’s how to debug when Cursor gets stuck,” “here’s the skill I wrote that solves this exact problem you’re facing.” This is developer advocacy turned inward. You’re embedded with Automattic's engineers, designers, and product teams, helping them level up their AI capabilities through hands-on teaching, tool development, and deep technical expertise. You’re technically experienced enough to build solutions yourself (scripts, agent skills, integrations, demos), but your superpower is translating that knowledge into practical help for others. You might also be an experienced software engineer with a passion for and experience in enabling others around you.  You’ll work in-person with our NYC AI team while supporting enablement efforts globally...
