Attack and Compliance Engineer (ACE)

Attack and Compliance Engineer (ACE)

Join Our Elite Security Team – Where Innovation Meets Impact!

Are you ready to become a technical leader who solves the most challenging security problems organizations face—including the ones they don't even know exist yet? As a Security Engineer, you'll be responsible for service delivery and expected to be a product subject-matter expert, working independently on small projects and collaboratively on large-scale enterprise deployments. 

You'll fuel solutions that make the deepest impact across organizations, working in a fast-paced environment where your insatiable thirst for learning new technologies will be celebrated and supported. 

What Makes This Opportunity Exceptional:

Our goal is never to fix and leave, but to share knowledge through comprehensive documentation and knowledge transfer, ensuring you build upon meaningful work. You'll be part of a large internal support group with extensive experience and benefit from our internal training program designed to increase your skills and keep pace with technology changes. We focus on enabling our engineers to become complete security professionals able to analyze security solutions, not just install and configure products. You'll gain a broad spectrum of knowledge and skills that allow you to give advice and direction relevant to today's threats. 

No Prior Experience with Automated Security Validation Required: While experience with Mandiant Security Validation Tool would be great, we'll train you on the tool if you have a solid foundation in cybersecurity. We're vendor neutral security engineers providing services that meet customer needs, not our own or that of vendors.
