Senior Security Engineer - Blockchain Infra & Zero-Trust

Mysten Labs, Inc.; Oregon; Ibrido; USD 130.000 - 210.000; Tempo pieno

Descrizione del lavoro

Mysten Labs, Inc. is seeking a seasoned Security Engineer to design and operate the security observability platform, defend endpoints, and lead threat investigations.

You will implement zero-trust models, run detections, and build production security services across cloud and on-prem environments. The role emphasizes hands-on engineering, telemetry pipelines, and collaboration with a global, remote-first team building web3 infrastructure using Rust, Python or Go, and modern tech.

Competenze

• Bachelor's degree in Computer Science, Computer Engineering, a relevant technical field, or equivalent practical experience.
• 5+ years in security engineering, detection and response, or infrastructure/SRE with a security focus, including hands-on incident response on endpoints and in the cloud.
• Experience operating an EDR, writing and tuning detections. Knowledge of macOS and Linux internals as attackers use them: persistence, credential theft, process injection, living-off-the-land binaries.
• Experience building or operating telemetry pipelines and a SIEM or security data lake at TB scale. Strong SQL, including detection logic over large datasets.
• Hands-on production engineering: Linux, containers, Kubernetes, at least one major public cloud, infrastructure as code, monitoring and alerting.
• Proficiency in Python or Go, and comfort with Rust or willingness to work in it (most of Mysten's stack are Rust).
• Working knowledge of identity: SSO (OIDC/SAML), phishing-resistant MFA, device trust, and how session and token theft work.
• Strong written communication: can run an incident channel and write the post-mortem.
• Interest in the web3 space is required.

Mansioni

• Build and operate the Security Observability & Data Platform (TB-scale ingestion, normalization, retention; detection layer).
• Own endpoint security across the fleet: EDR, binary authorization, and hardening baselines with IT Operations.
• Lead threat hunting, investigations and insider-threat work; manage end-to-end incidents.
• Build and run security services: zero-trust AuthN/AuthZ, blocking service, application proxy, inventory, and compliance as code.
• Build and run the agent platform (local and Kubernetes); use LLM agents to automate triage, enrichment, investigation, and response.
• Review infrastructure and cloud designs (Kubernetes, AWS/GCP, bare metal, CI runners) for security and promote shared services.
• Run red-team and adversary-emulation exercises; turn results into detections and fixes.
• Write runbooks and post-mortems that non-technical teammates can follow at 3 a.m.
