Sr. Engineer - Cloud SDET - Lightning (Hybrid)

CrowdStrike•Redmond, WA
•$140,000 - $215,000•Hybrid

About The Position

CrowdStrike is seeking a Senior Software Developer in Test (SDET) to join the Lightning team. This role involves a hybrid contribution to both the design and creation of custom test tooling, frameworks, and systems, as well as contributing to the core product code. The SDET will act as a backend developer and test SME, validating key features across processing, data, and customer-facing application layers. The role requires ensuring the system supports low-latency malware prevention, manages thousands of events per second, queries terabytes of data, and delivers accurate information to the endpoint. Responsibilities include guiding design discussions and code reviews with a focus on quality, serving as the team's SME for code hygiene, and contributing to service operations. Testing concerns span functional, performance, contract, and chaos/resilience engineering. Cybersecurity experience is a plus but not a prerequisite. This team values collaboration, high ownership, schedule flexibility, and trust in expertise for test architecture design and implementation.

Requirements

  • 9+ years of experience (Avg. YoE: 11-16 years) as either/both an SDET or Backend Developer (combined)
  • Experience building testing frameworks and tooling for a Cloud SaaS product or other SOA with similar cloud components
  • Experience contributing to or defining testing strategy at a team or organizational level
  • Strong debugging skills: ability to spot design flaws, race conditions, and performance bottlenecks in complex architectures
  • Expertise in any of: Golang, Python, Java, Kotlin, Rust, or C/C++ — Go is our primary 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, Cassandra, Redis, Kafka, and/or similar technologies — you don't need all of these specifically, but transferable skills in each category are a must
  • Experience with distributed systems and scalability challenges
  • Experience with cloud services, such as AWS or GCP, 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)
  • Experience mentoring engineers and driving quality culture across a team or organization

Nice To Haves

  • Experience building, operating, validating, and scaling low-latency cloud services using gRPC and event-driven messaging systems such as Kafka
  • Experience building and shipping cloud-connected endpoint software
  • Experience with at least one cloud environment, such as AWS, GCP, or OCI
  • Experience leveraging AI and agentic tools to enhance testing workflows and automation

Responsibilities

  • Build and own end-to-end validation of Lightning services across cloud-side and Falcon Sensor interactions, spanning component, integration, and application levels, while continuously improving test and validation processes
  • Build and own Lightning-specific test tooling and frameworks, while leveraging and contributing to shared organization-wide testing tools and infrastructure
  • Define and drive testing strategies across functional, performance, contract, and chaos testing concerns
  • Guide technical design reviews in quality SME capacity, to provide clear guidance on testability, quality, and code hygiene
  • Leverage new open source solutions to build new tools that test things in new ways
  • Own code reviews with a focus on quality, serving as the team's SME for code hygiene
  • Contribute to service operations, including improving overall service observability and monitoring, root cause analysis of production issues, and implementing quality improvements to prevent future outages
