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.
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.
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).
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.
Remote‑first: work wherever you’re most effective; optional travel to team or industry events. Ideally East Coast or European time zone.
Freedom & ownership culture: no time tracking, minimum bureaucracy—only results matter.
