Join to apply for the Head of Infrastructure Security role at Matter Labs

At Matter Labs, we believe freedom drives progress and prosperity. We don’t see ourselves as a company, but as a team aligned around a single mission : to advance personal freedom for all (see ZK Credo).

To achieve this goal, we’re building zkSync -a credibly neutral, fully open source technology stack and network on top of Ethereum, which is owned and governed by its community. We use advanced cryptography called zero-knowledge proofs to scale Ethereum infinitely without compromising on security or decentralization. With a world-class team, a community of over 1M supporters across Twitter and Discord, and hundreds of millions of dollars in funding, we have the resources to achieve our mission.

The Role : Head of Infrastructure Security

We are looking for a deeply experienced and driven security leader to join as Head of Infrastructure Security - a role that bridges traditional infrastructure security with protocol-level cryptographic assurance.

You will own and drive security across both our cloud-native and on-chain systems, working closely with protocol engineers, DevOps, and product teams to ensure we remain secure at every layer. You’ll also be responsible for building and mentoring a world-class security team, and ensuring strong, scalable security practices across the organization.

What You’ll Be Doing

• Lead security strategy and execution across both infrastructure and protocol layers.
• Drive secure implementation verification of cryptographic protocols, including hands-on review and testing.
• Partner closely with engineering, DevOps, and protocol teams to improve security posture.
• Conduct deep threat modeling, design reviews, and architecture assessments.
• Build and manage a high-performing security team.
• Oversee vulnerability management, detection, and incident response.
• Set and maintain robust engineering and security processes.
• Educate and mentor the broader team on secure development practices.
