About The Role:

CrowdStrike is seeking an Sr Engineer in Exposure Management Group for our Sensor team. This is a systems software role.

• Participate in planning; help scope work, identify dependencies, and flag technical risk early
• Mentor and grow more junior engineers through direct feedback, pairing, and collaborative code and design review
• Investigate and resolve production incidents and complex escalations; build the team's shared knowledge of failure modes at fleet scale
• Champion improvements in end-to-end testing and validation for components with strict correctness and reliability requirements

What You’ll Need:

• BS/MS in Computer Science or related field, or equivalent work experience.
• In depth knowledge with C/C++
• Expert understanding of Linux, Windows, OR Mac OS internals.
• Experience with NMAP internals, Lua/NSE scripting, Go and other Vulnerability scanning frameworks is desirable.

• Demonstrated experience collaborating with teams to successfully deliver major features and releases.
• Ability to lead, mentor, communicate, collaborate, and operate effectively within a geographically distributed team.
• Proven experience utilizing AI technologies to enhance decision-making, streamline workflows and processes, improve efficiency and drive business outcomes.
