About the Role:

This is a Software Development Engineer in Test (SDET) position on the macOS sensor engineering team, in the detection space. At CrowdStrike, SDETs and SDEs work together in combined engineering teams. SDETs are key contributors on the team, focusing on the quality of the sensor. SDETs use their strong software development skills to build effective tools, harnesses, and specialized tests to assure that quality goals are met for each new capability. SDETs also participate actively in design and code reviews, and collaborate with the research, hunting, and cloud teams to ensure end-to-end sensor functionality.

Successful engineers in this role have: an understanding of macOS kernel and user space, a passion for continuous learning to keep up with an ever-changing threat landscape, a creative mindset for designing new code validation methods to increase the quality, performance and the reliability of the shipped code.

What You'll Do:

• Analyze complex software features, and build effective test strategies and test designs

• Extend our existing codebase utilizing Swift, C++, Python, and other tools and DSLs (domain specific languages) as appropriate, to increase the testability and debuggability of  the code 

• Build useful tools, frameworks, and test setup to use for developing tests effectively; the goal is to maximize the coverage of automated testing at scale and minimize the manual testing effort

• Identify and write specialized tests necessary that are not feature-specific but are still important to ensure the quality of the system as a whole – performance, scalability, limits etc.

• Debug bugs found through test or customer cases to identify root cause and use the input to improve tests

• Work collaboratively with product and release management to control risk, improve quality, and streamline our release cycles

• Rigorous product and test code reviews with an eye towards improving the security and robustness of the system as a whole

• Leverage your understanding of engineering best practices, including topics like secure coding, testing paradigms, debugging, performance, code reviews, CI/CD and OS internals, to ensure that our sensor code is fast and reliable

• Troubleshoot product issues as reported from customers responsively and other projects as assigned

• Be an energetic ‘self-starter’ with the ability to take ownership and be accountable for deliverables, both individually and when leading a team

What You'll Need:

• 5+ years of experience with either:

  • Pentesting, reverse engineering, threat detection or analysis; and an interest in software quality, validation and testing, or

  • Designing, building, and delivering frameworks and test harnesses to ship  high-quality software in at least one of the following: Swift, C/C++, Python, Objective-C; and a demonstrated interest in security.

• 1 year of experience in using big data to analyze and monitor software quality metrics. 

• Low-level OS knowledge of macOS and/or Linux operating system internals, components, APIs and/or frameworks.

• Team player – able to lead, mentor, communicate, collaborate, and work effectively in a distributed team, to clearly articulate thoughts & designs to peers and upper management

Bonus Points:

• Prior security experience, particularly always-on systems, endpoint threat detections or sensor development. Familiarity with the threat landscape on Linux/Windows is a plus

• Experience with macOS Frameworks and events relevant to security and recent familiarity with the latest developments in macOS 

• Experience developing 24/7 enterprise software, including CI, testing, debugging, performance tracing, release management, telemetry analysis and issue handling

• Expertise in using performance profiling tools and debuggers to analyze crash dumps
