Job Description

Sr. Engineer - Sensor, (Hybrid, CAN)

CrowdStrike

As a global leader in cybersecurity, CrowdStrike protects the people, processes and technologies that drive modern organizations. Since 2011, our mission hasn’t changed — we’re here to stop breaches, and we’ve redefined modern security with the world’s most advanced AI-native platform. We work on large scale distributed systems, processing almost 3 trillion events per day and this traffic is growing daily. Our customers span all industries, and they count on CrowdStrike to keep their businesses running, their communities safe and their lives moving forward. We're proud to work for a mission-driven company leveraging AI to transform the way we work. CrowdStrikers drive their careers through flexibility and autonomy while also being expected to contribute to a culture of responsible AI adoption, experimentation, and innovation. We use an AI-first mindset as a force multiplier to proactively and continuously accelerate execution, build expertise, uncover insights, and solve complex problems. We’re always looking to add talented CrowdStrikers to the team who have limitless passion, a relentless focus on innovation and a fanatical commitment to our customers, our community and each other. Ready to join a mission that matters? The future of cybersecurity starts with you. About the Role: The Core Services team owns the sensor infrastructure that every CrowdStrike endpoint depends on: secure network communications, cryptographic operations, content delivery, and secure local data storage. These are foundational runtime components that execute on every protected endpoint across Windows, Linux, and macOS. As a Senior Engineer on this team, you will build, extend, and maintain the low-level systems that connect the Falcon Sensor to the CrowdStrike cloud — handling connection lifecycle management, traffic and protocol management, cryptographic integration, content delivery, and on-device storage at endpoint fleet scale. This is a systems software role. You'll work close to the OS across multiple platforms, reason carefully about correctness and performance under real-world load, and hold a high engineering bar in a codebase where reliability is non-negotiable. You will work cross-functionally with peer engineers across Mac, Linux, Windows, and many other teams inside and outside your core organization in a diverse environment. You're stepping into a team with established component ownership and a charter that is actively expanding. The engineering spans cross-platform correctness, performance-sensitive code paths, and cryptographic and network components where a defect is a security event. You'll work alongside engineers who take the reliability bar seriously; regressions here land on every protected endpoint simultaneously. If you want to build foundational software that runs at global scale and has a direct impact on security outcomes, this is the role. What You'll Do: - Design, implement, and own core sensor infrastructure components: network communications stack, connection lifecycle and traffic management, cryptographic integration, content delivery, and on-device secure storage - Take end-to-end ownership of your work — from design through production validation across Windows, Linux, and macOS, including the testing and rollback story - Serve as a technical integration point with sensor, cloud communication, and policy teams; proactively own interface contracts and surface breaking changes early - 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 - Champion improvements in end-to-end testing and validation for components with strict correctness and reliability requirements What You'll Need: - Strong foundation in systems software engineering; hands-on experience in C and/or C++ in a low-level systems context - Solid technical grounding in network protocols, connection management, and traffic and protocol management; working familiarity with cryptographic integration and content delivery - A "learn it all" mindset with curiosity to dive deep into unfamiliar domains and adapt quickly as technology and requirements evolve - 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 - Experience with cryptographic service design or integration with security-critical cryptographic libraries - Experience building or operating content distribution or configuration delivery systems at endpoint fleet scale: atomic updates, staged rollout, versioning, and rollback-safe delivery - Open source contributions, technical writing, or a visible engineering presence through conference talks or published work #LI-CW1 Benefits of Working at CrowdStrike: - Market leader in compensation and equity awards - Comprehensive physical and mental wellness programs - Competitive vacation and holidays for recharge - Paid parental and adoption leaves - Professional development opportunities for all employees regardless of level or role - Employee Networks, geographic neighborhood groups, and volunteer opportunities to build connections - Vibrant office culture with world class amenities - Great Place to Work Certified™ across the globe CrowdStrike is proud to be an equal opportunity employer.
