SDET - AI Detection and Response (AIDR) (Hybrid)
About The Position
CrowdStrike is seeking a Software Developer in Test (SDET) to join our AI Detection and Response (AIDR) team. In this role, you will own end-to-end quality for the next generation of AIDR services — a platform that processes millions of AI security events per second and manages petabytes of critical AI data. This is a hands-on, coding-intensive role on par with product development. You'll build and own AIDR-specific test tooling and frameworks, while leveraging and contributing to shared organization-wide testing infrastructure. Your work will span validation across both cloud-side backend services and UI applications, ensuring the system behaves correctly at every stage — from individual components to full system behavior. Testing concerns span functional, performance, contract, and chaos/resilience engineering. This is an opportunity to work at unprecedented scale with cutting-edge cloud technologies while making a direct impact on organizations worldwide, protecting them from sophisticated AI-based threats. This role is hybrid, requiring 2-3 days per week on-site at one of the posted locations.

- Strong computer science fundamentals (algorithms, data structures, distributed systems)
- Expertise in at least one of: Golang, Python, Java — Go is our primary backend language, but strong engineers in any of these are welcome and we support ramp-up
- Experience in a cloud distributed systems stack: e.g., Kubernetes, PostgreSQL, Redis, Kafka, and/or similar technologies — transferable skills in each category are a must
- Experience with cloud services such as AWS, GCP, or OCI, particularly compute and storage offerings
- Experience with CI/CD pipelines and integrating automated testing into deployment workflows
- Experience developing and deploying in containerized environments (e.g., Docker, Kubernetes)
- Extensive experience with testing tools and best practices (e.g., Jest, QUnit, Cypress, Playwright, JUnit, TestNG)
- Experience testing REST and/or gRPC APIs and real-time or high-volume data systems
- Proven experience utilizing AI technologies to enhance decision-making, streamline workflows and processes, improve efficiency, and drive business outcomes
- Strong cross-group collaboration and interpersonal communication skills working across engineering organizations
- Experience mentoring engineers and driving quality culture across a team or organization
Nice To Haves
