Your Role

As a Security Engineer on the Polygon Labs SecOps team, you’ll play a critical role in protecting core infrastructure across both Web2 and web3 environments. This is a rare opportunity to join a highly technical and collaborative team working on the front lines of blockchain and cloud security. You’ll be working in a high-stakes environment, supported by a globally distributed security team that shares operational responsibility, 24/7, around the clock.

You’ll own a wide range of operational security initiatives – from real-time threat detection to custom web3 infrastructure controls. If you’re passionate about working in high-stakes environments, thrive on solving complex challenges, and want to shape the next generation of security in web3, we’d love to have you on board.

Your Responsibilities

• Lead and evolve SIEM operations: manage log feeds, fine-tune detection rules, and respond to real-time threats using Datadog SIEM, EDR, and on-chain monitoring tools.

• Drive key web3 security initiatives including multisig controls, signer access, attestations, and audit processes.

• Develop and enforce operational security best practices across Web2 and web3 systems.

• Collaborate cross-functionally to secure cloud infrastructure environments (GCP) and web-facing services.

• Build and maintain automation for tooling, alerting, vulnerability scanning, and compliance workflows.

• Conduct internal security audits and support third-party risk assessments to continuously strengthen our infrastructure.

• Contribute to secure infrastructure-as-code practices, even if not directly managing Terraform pipelines.

What You’ll Need

• 2 – 5 years of experience in security operations, with exposure to both traditional cloud environments and web3 technologies.

• Hands-on experience with incident response, SIEM platforms, and endpoint detection and response (EDR) tools.

• Strong understanding of blockchain security concepts: smart contract risks, multisig wallets, and on-chain monitoring.

• Proficiency with GCP security principles and tooling. DevOps experience is a plus.

• Programming experience in Python, TypeScript/JavaScript for automation and monitoring use cases. Knowledge of Solidity is a plus.

• Excellent collaboration, communication, and problem-solving skills – along with a high sense of ownership and adaptability in a fast-moving industry.

Preferred Qualifications

• Familiarity with security frameworks such as CIS Controls, ISO 27001, SOC 2, NIST CSF, or MITRE ATT&CK.

• Foundation security certifications such as CompTIA (e.g. Linux+, Security+) expected. CompTIA CySA+, GIAC (e.g., GCIH, GCIA), or GCP Security Specialty preferred. Additional certifications like Datadog Fundamentals are a plus.

• Exposure to web3 security certifications (e.g., CryptoConsortium C4) is a plus.
