Intact, the world’s leading software solutions provider for the Testing, Inspection and Certification (TIC) industry, is looking for a Senior Platform Engineer (Identity, APIs and Integration) to build the identity, authorization, and integration backbone of our new platform.

For more than 25 years, our software has helped certification bodies, accreditation bodies, and scheme owners digitize complex assurance processes. Now we’re building a modern, domain-driven software-as-a-service (SaaS) platform and transforming how our engineering organization works.

In this role, you’ll design the identity, authorization, and multi-tenant model that every layer of the platform depends on. You’ll also own the APIs and event layer that connect our product squads, new modules, and our established platform (IPF).

This is one of the largest transformations in our company’s history. You’ll join us early enough to shape not only what we build, but how we build it.

Sounds exciting? We’d love to hear from you.

Are you ready?

• Own the identity and authorization model, including the tenant, customer, organization, and role structure
• Run platform APIs as products: stable, versioned, documented in OpenAPI, and backed by service level agreements (SLAs) and deprecation policies
• Build the event and messaging library, database-backed at first and ready to swap for a message bus later, so IPF can publish events through SQL
• Design the compatibility and translation layer between IPF and new modules
• Ensure access control and tenant isolation for AI features
