Mozilla is building a position in open source AI — through research, community, tooling, and public advocacy. This is a project-based prototyping role. You'll build working demonstrations of what open AI infrastructure can do: developer surfaces, integrations, and small applications that make abstract ideas tangible and invite conversation. You'll work in public, alongside the people building our community and social presence.
Job Responsibility:
Build working prototypes of developer surfaces, tooling integrations, and applications on top of open source AI infrastructure
Work with coding agents and AI-assisted development tools as a core part of your workflow
Translate concepts, framing documents, and strategy ideas into demonstrations
Collaborate closely with the social media and community team
Contribute to Mozilla's open source repositories and work in the open
Stay close to the open source AI ecosystem
Help evaluate and opine on open source AI tools, stacks, and developer surfaces
Requirements:
Solid software engineering fundamentals
Demonstrated comfort working with coding agents and AI-assisted development tools (Cursor, Claude Code, or equivalent)
Experience with the open source AI stack: inference, orchestration, evaluation, or adjacent layers
Fluency in Python and/or TypeScript
Experience building APIs, developer-facing tools, or integrations
A strong sense of what makes a prototype useful for a conversation
Comfort working in public — open repos, community feedback, building in the open
Strong written communication
What we offer:
Flexible work environment
Industry-leading paid parental leave
Reimbursement for professional development (up to $3,000/year)
A work setup including the latest hardware and software of your choice
