Job description

Upstream contributions, open-source strategy, technical education, speaking, mentorship, and community work.

The mandate.

Own the outcome, stay close to the implementation, and improve the system around the work.

Connect credible engineering work, contributor experience, product strategy, and public education into an open-source programme people can trust and participate in.

The role should create healthy upstream relationships and useful feedback loops, not treat community as a distribution channel with a Discord server attached.
