About The Position

As a Security Engineer, Product Infrastructure at the forefront of blockchain security in SaaS, you will dive deep into cloud, product, and cutting-edge Security AI building. This is your chance to directly impact the security posture of a mission-critical platform. You'll work hands-on with elite tools like Wiz and our comprehensive security stack to relentlessly monitor and respond to security threats across our dynamic AWS and Kubernetes environments.
You will be a key partner to product and platform engineering teams, driving critical remediation efforts. Beyond daily operations, you will participate in a shared on-call rotation—backed by senior engineering expertise—to tackle high-stakes production security incidents, ensuring our controls are not just reliable, but unbeatable. Join us to engineer the future of decentralized trust and security.

Requirements

• Hands-on experience in security engineering
• Hands-on experience with at least one security tool used in modern cloud or product environments (Wiz, Orca. SonarCloud, Upwind, or similar)
• Scripting experience in Python or Go (or similar) to automate repetitive tasks, integrate tools, or build small utilities that make the team more efficient.
• Infrastructure-as-Code (Terraform) and Kubernetes - you don’t need to be an expert yet, but you should be comfortable reviewing IaC and/or K8 manifest.
• Prior participation in an on-call rotation for production systems or security incidents, even in a shadowing or secondary role.
• Experience working with tickets, incidents, or production issues, and following a structured process to investigate, document, and resolve or escalate them appropriately.
• Strong communication skills, with the ability to explain what you’re seeing and what you recommend as a next step to both technical and non-technical audiences.
