Role

Who you are

This role is ideal for someone who thrives in high-impact environments, enjoys solving complex technical challenges, and is motivated by the mission of protecting open-source and decentralized infrastructure
Strong Infrastructure Security Background
Hands-on experience securing cloud-native environments (e.g., AWS, GCP), Kubernetes, CI/CD pipelines, and internal systems
Deep Technical Fluency
Practical knowledge of threat modeling, incident response, vulnerability management, and systems architecture
IaC & DevSecOps Mindset
Familiarity with Infrastructure as Code (Terraform, etc.), secrets management, and security automation tooling
Bias for Action
A self-starter who’s comfortable with ambiguity and can drive security work through delivery — not just assessment
Collaborative Communicator
Able to partner across teams, raise risks constructively, and translate complex security concepts to technical and non-technical stakeholders
Web3 Awareness (Nice to Have)
Familiarity with the security considerations of decentralized infrastructure and open-source ecosystems. Bonus for knowledge of Ethereum, Solidity, or ZK-related tech

What the job involves

Join Matter Labs as a Senior Security Engineer (Infrastructure) and play a critical role in securing the infrastructure that powers zkSync
You’ll work across cloud, application, and systems layers to build and maintain robust defenses. Partnering closely with DevOps, engineering, and protocol security to embed security into everything we ship
Infrastructure & Cloud Security
Design and implement secure infrastructure; including hardening cloud environments, containers, and CI/CD pipelines
Detection & Response Readiness
Help build detection and monitoring systems (e.g., SIEM, alerting pipelines) to ensure early threat detection and effective incident response
Secure Systems Design
Collaborate with engineers and DevOps to identify security risks in architecture reviews, system upgrades, and deployment plans
Infrastructure as Code (IaC)
Contribute to the design and review of Terraform, Ansible, or similar IaC, ensuring security is embedded from the ground up
Security Reviews & Remediation
Participate in threat modeling, internal audits, and hands-on vulnerability remediation across our stack
Cross-Team Collaboration
Work closely with Protocol Security, DevOps, and Product Engineering to align on shared security goals and ensure coverage across the full lifecycle
Optional: On-chain Infra Anomaly Detection
Help implement tools to detect unusual infrastructure-level activity from on-chain signals (e.g., misuse of credentials or suspicious deployment patterns)

Our take

While the Ethereum network offers users highly rated security, the trade off is that its network volume doesn’t have enough capacity to allow for fast and cheap transactions. Matter Labs is one of a small number of companies that are building scaling protocols through its zero-knowledge proof driven product, zkSync.

It’s not the only company of its kind, with the likes of Arbitrum and Optimism also receiving plenty of publicity and funding. However, Matter Labs zero-knowledge proof approach has been praised for both its transaction speed and security. If it was easy however, many more companies would be doing it, so it appears that Matter Labs has made a significant headstart on the competition.

Over the last couple of years, the startup has secured some major funding from high-profile investors such as Andreessen Horowitz (a16z), and Union Square Ventures. Matter Labs released its renamed ZkSync Era - a zero-knowledge, open-source security platform on Ethereum in 2023. Matter Labs is now predicting zero-knowledge cryptography to outlive alternative "optimistic" security tech from the likes of Arbitrum.
