Identity and Access Management (IAM) Engineer

About Proton

Join Proton and build a better internet where privacy is the default

Proton was founded in 2014 by scientists from CERN on a simple truth: privacy is a fundamental human right. Since then, we’ve built the world’s largest encrypted email service (Proton Mail) and expanded into Proton VPN, Proton Drive, Proton Pass, and Proton Calendar—tools used by millions globally to protect their freedom, fight censorship, and keep their data safe. In some situations, Proton has literally helped save lives!

We are profitable, independent (no VC control), and selectively hire from the top ~1% of applicants. Our 700+ team members across 50+ countries come from leading organizations and elite academic backgrounds. We move fast, keep hierarchy light, and prioritize impact over optics. If you want to do meaningful work with exceptionally high-caliber people, this is it. Join us and do work you can truly be proud of. Check our open-source projects here!

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 midPoint) 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.

What you will do

IAM Architecture & Implementation

• 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, and open-source environments.
• Collaborate closely with cross-functional engineering teams to integrate the IAM platform seamlessly into our existing infrastructure and internal tools.

User Lifecycle & Governance

• 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.

Authentication & Access Control

• 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.

Automation & Systems Engineering

• 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.

Job requirements

• 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, midPoint).
• 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.

Preferred qualifications

• Advanced proficiency in implementing, configuring, and maintaining midPoint.
• 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).

Success in This Role

• 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 are optimized to enforce strict security baselines without breaking organizational agility.
