Careers

Build AI that runs where the work happens

Gammaxon is a team of engineers, analysts, and security people who put models into places a hosted service cannot reach. We are hiring across engineering, security, and sales.

Benefits

Health and wellbeing

Medical, dental, and vision for you and your family, with a mental-health benefit that is not capped by visits.

Time to recover

Twenty-five days of paid leave, plus the week between the winter holidays, and recovery days after long deployments.

Growing your craft

A yearly learning budget, conference travel, and paid research time for the platform and science teams.
