Identity and Access Management; IAM Engineer

Role Overview

The Identity and Access Management (IAM) Engineer will play a critical role in designing, implementing, and securing Proton's core internal identity infrastructure. As we scale globally, maintaining robust access controls and seamless identity governance is paramount to safeguarding our systems and supporting our growing team across Europe and beyond.

This role bridges modern system engineering, security architecture, and identity lifecycle automation. Sitting within our technical infrastructure and security ecosystem, you will take ownership of our core IAM stack, which leverages a strong foundation of self-hosted, open-source technologies (eg Keycloak, and mid Point) alongside key enterprise solutions like Duo. You will collaborate closely with cross‑functional teams to integrate identity solutions into existing architectures, automate operational workflows, and design Proton-specific access models that strike the perfect balance between strict zero-trust security and team velocity.

• Design, implement, integrate, and maintain Proton’s core IAM solutions, ensuring high availability, security, and scalability.
• Manage and maintain systems and applications built on self-hosted, open‑source environments.
• Collaborate closely with cross‑functional engineering teams to integrate the IAM platform seamlessly into our existing infrastructure and internal tools.

• Develop, implement, and maintain secure automated processes for user provisioning, de‑provisioning, and overall account lifecycle management to ensure seamless onboarding and offboarding.
• Design and manage identity governance processes to ensure proper management of user access rights, entitlements, and strict alignment with organizational compliance standards.
• Conduct regular audits, assessments, and access re‑certification campaigns to proactively discover and remediate access anomalies.

• Configure, optimize, and manage access control, authentication, and authorization mechanisms.
• Develop and enforce granular policies for identity and access management in alignment with organizational security goals.
• Support, maintain, and contribute to specialized infrastructure projects.

• Leverage your scripting and automation expertise to eliminate operational toil and streamline identity workflows.
• Write high‑quality, maintainable code for infrastructure automation and configuration management.

• Proven experience as an IAM Engineer with a deep focus on identity management within a production environment.
• Strong, hands‑on experience working with open‑source IAM solutions (e.g., FreeIPA, Keycloak, mid Point).
• Deep technical understanding of core identity protocols and standards, specifically LDAP, SAML, OAuth, and OIDC.
• Strong proficiency in scripting languages (e.g., Python, Bash) for automation, integration, and tooling tasks.
• Solid background in system engineering, particularly with managing, deploying, and maintaining complex self‑hosted solutions.
• Ability to adapt quickly in a fast‑paced environment.
• Strong communication and interpersonal skills, with a proven track record of collaborating effectively across engineering and non‑engineering teams.

• Advanced proficiency in implementing, configuring, and maintaining mid Point.
• Hands‑on experience with configuration management and infrastructure‑as‑code tools (such as Ansible, Puppet).
• Prior experience managing identity governance frameworks, including compliance reporting and access re‑certification campaigns.
• Relevant industry certifications in IAM‑related technologies (e.g., CIDPRO certification).

• Proton’s identity lifecycle processes (onboarding, offboarding, and transitions) become fully automated, secure, and seamless.
• Internal open‑source IAM solutions are robustly engineered, highly available, and perfectly integrated across our infrastructure.
• Identity governance and re‑certification campaigns are managed effectively with minimal manual overhead and clear auditability.
• Authentication mechanisms and access controls…
