SaaS engineering teams split broadly into product engineering (frontend, backend and full-stack), platform and infrastructure (SRE, DevOps, cloud), security, data and machine learning, and quality. Most titles on this page fall into one of those groups. Forward-deployed and solutions engineers work closer to customers, so they are listed under Sales or Customer Success.

Questions about Staff & principal Engineering jobs at AI companies
Where do these Staff & principal Engineering jobs at AI companies come from?
Every job is pulled from the company’s own hiring system (Greenhouse, Lever, Ashby, Workable or Rippling) once an hour. We do not accept paid or reposted listings, so each role links back to the company’s live careers page.
What happens when I click Apply?
You go straight to the job on the company’s careers site and apply there. We never host applications and never see or store your details.
Why don’t all jobs show a salary?
We only show pay when the company publishes it in the job post. Around 82% of the roles on this page include a range today. Sort by “Salary listed first” to see those roles at the top.
How do I know a job is still open?
We check every company’s job board hourly. When a role is removed from the careers page, we remove it here within the hour and point you to similar open roles.
What does “Remote (Europe)” mean?
It means the company hires remotely but only within that region, usually for tax, contract or time-zone reasons. “Remote (Worldwide)” roles have no location restriction.
