About these roles
Engineering jobs at SaaS companies
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.
Pay depends heavily on level and location. Where companies publish a range, the typical role on this page lists $266k–$405k in the US, £194k–£315k in the UK (median published minimum and maximum). About 35% of the roles here include a salary; use Salary listed first to see those at the top.
39 SaaS companies are hiring for these roles right now, led by OpenAI, Anthropic, and Scale AI.
Questions about SaaS Engineering jobs
Where do these SaaS Engineering jobs come from?
Every job is pulled from the company’s own hiring system (Greenhouse, Lever, Ashby or Workable) 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 35% 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.
Are all of these roles based in the United Kingdom?
Each role has at least one office or hiring location in the United Kingdom. Some postings list several countries or also allow remote work; the location chips on each job show the full picture.
