About the Role:
This is a systems software role on the Core Libraries team, which owns the shared Windows, Linux, and macOS libraries that the sensor depends on. Examples include libraries used to handle memory allocation, securely parse and process files, and manage threads and work items. These libraries are widely used within the sensor, and the success of this team is instrumental to the success of the overall sensor platform.

You will work closely with sensor developers from all organizations within CrowdStrike to provide high-quality libraries which meet the needs of fast-paced sensor development, without sacrificing quality and reliability.

This role is hybrid, requiring 2x days per week on-site at one of the posted locations.
What You'll Do:
Work across organizations and functional teams to gather library requirements, then design, implement, and test the resulting libraries
Take end-to-end ownership of your work — from design through production validation across Windows, Linux, and macOS, including the testing and rollback story
Drive technical proposals and design docs; lead design reviews for your area and provide substantive review feedback that raises the bar for the whole team
Represent the team's technical position in cross-org planning and architecture discussions; communicate tradeoffs and risks clearly to engineering, product, and program partners
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

changing them"
Experience reasoning about reliability and correctness for software that runs at endpoint fleet scale
Cross-platform exposure across Windows, Linux, and/or macOS; ability to reason about portability, behavioral consistency, and platform-specific constraints
Solid design and problem-solving instincts; ability to own ambiguous technical problems and drive them to clean resolution
Ability to influence technical direction across team boundaries without direct authority, using design docs, prototypes, and well-reasoned technical positions
Strong written and verbal communication; able to convey complex technical topics clearly to both technical and non-technical audiences
Strong engineering fundamentals: testable, reviewable code; careful about edge cases; high personal bar
Ability and willingness to travel occasionally for team offsites and in-person meetings
Proven experience utilizing AI technologies to enhance decision-making, streamline workflows and processes, improve efficiency and drive business outcomes.
Bonus Points:
Background in endpoint security, EDR, kernel-adjacent software, or sensor platform engineering
Past experience in designing, implementing, and maintaining cross-platform software libraries, with a focus on ABI stability, versioning, and backward compatibility
Open source contributions, technical writing, or a visible engineering presence through conference talks or published work
