Principal Software Engineer

Siteimprove is the leader in agentic content intelligence. Our platform brings accessibility, analytics, SEO/AEO, and content strategy together in one system, where AI agents work alongside marketing and digital teams to produce content that is accessible and easy to find. Every customer, user, and increasingly every AI agent that touches the Siteimprove platform goes through systems owned by the Access team: sign-in, single sign-on, federation with customer identity providers, and the authorization layer that decides who can see and do what.

We're looking for a Software Engineer with real depth in authentication, authorization, and identity provider (IdP) systems. You'll design and build the services that secure the Siteimprove platform, work with enterprise and public-sector customers' SSO setups, help us meet FedRAMP requirements, and shape how AI agents and machine clients authenticate against our APIs and MCP servers.

This is a hands-on role with a lot of technical ownership. You'll be one of the people others on the team, and across engineering, come to with identity questions.
