Principal Security Engineer – Cloud Platform (Remote, UK)
We've partnered exclusively with a scaling infrastructure company that's fundamentally transforming how digital and physical components interact in the age of AI. Their core mission is to empower teams to build and deploy sophisticated systems by providing scalable, secure, and robust infrastructure solutions for development, deployment, and scaling.

They're looking for a Principal Security Engineer to lead the architecture and development of its next-generation cloud security platform.

This is a high-impact, hands-on role where you'll design and build a full Identity & Access Management (IAM) platform from scratch—powering secure access, identity federation, and zero-trust controls for large-scale AI systems.

You'll shape the security foundation of a cutting-edge cloud platform, working across core backend services and collaborating with infrastructure and ML teams. Expect huge technical ownership, complex distributed problems, and the chance to influence engineering standards across the organisation. 
Requirements:

  • Strong backend engineering skills (preferably
    Golang
    ) in cloud-native environments.
  • Deep expertise in
    IAM protocols
    (OAuth2, OIDC, SAML, JWT) and security architecture.
  • Experience
    building an IAM platform or major IAM components from the ground up
    .
  • Solid understanding of cryptography (PKI, TLS, key rotation, secrets management).
  • Experience with microservices, distributed systems, and relational databases (PostgreSQL).
