Sr. Engineer - Cloud SDET - Lightning (Hybrid)

About the role

Lightning is a suite of services in the CrowdStrike cloud that expose sub-second, near-real-time APIs enabling Falcon Sensors to rapidly obtain threat information. Operating at massive scale, Lightning processes trillions of threat events daily within tight latency constraints - where performance and availability are critical to sensor operation and customer protection. CrowdStrike is seeking a Senior Software Developer in Test (SDET) for a hands-on, coding-intensive role on par with product development. The Sr. SDET will build and own Lightning-specific test tooling and frameworks, while also leveraging and contributing to shared organization-wide testing tools and infrastructure. This critical role is responsible for validating both cloud-side services and Falcon Sensor interactions end-to-end, ensuring the system behaves as expected at every stage. Testing concerns span functional, performance, contract, and chaos testing. The Sr. SDET will participate in design discussions and code reviews with a focus on quality, serve as the team's SME for code hygiene, and contribute to service operations - all while continuously expanding test coverage and capabilities. This role is hybrid, requiring 2-3 days per week on-site in one of the posted locations. This is a welcoming and flexible team that prizes collaboration over competition, providing opportunities to learn new skills, mentor developers at all levels, and contribute to the direction of both the team and its products. This is a high trust environment where team members manage their own time, take time off as needed, and are rewarded with competitive salaries and equity.
