#WeAreCrowdStrike and our mission is to stop breaches. As a global leader in cybersecurity, our team changed the game. Since our inception, our market leading cloud-native platform has offered unparalleled protection against the most sophisticated cyberattacks. We’re looking for people with limitless passion, a relentless focus on innovation and a fanatical commitment to the customer to join us in shaping the future of cybersecurity. Consistently recognized as a top workplace, CrowdStrike is committed to cultivating an inclusive, remote-first culture that offers people the autonomy and flexibility to balance the needs of work and life while taking their career to the next level. Interested in working for a company that sets the standard and leads with integrity? Join us on a mission that matters - one team, one fight.
About the Role:
We are seeking a Sr. Software Engineer, SDET - Windows Sensor. You'll join our Windows Sensor Team as part of our Detections Platform Group, which focuses on building common frameworks to leverage the power of our endpoint agent to effectively and quickly deliver actionable insights to customers and other teams within Crowdstrike. The Detections Platform team is central to CrowdStrike's mission - "We Stop Breaches." Our goals are to improve visibility, accelerate detections, and move faster than our adversaries.
On our team, a Software Development Engineer in Test (SDET) is a software engineer who focuses on the tools and methods used to ensure that our systems behave in the intended ways. This work ranges from formal modeling to verifying designs to building frameworks that make it easier for other developers to write unit tests. The code is not a black box - if it needs to change to be testable, you can and should change it.
More specifically, you'll be part of the engineering team enhancing our endpoint sensor for Windows. This team builds frameworks which interact with the file system, operating system, and registry to surface interesting events for analysis by the detections engine. This team owns the file system minifilter and writes both kernel- and user-mode code.
CrowdStrike is a remote-friendly organization, and you'll be collaborating with developers in many locations. Remote applicants in Ireland are welcome. Occasional travel (<10%) is required.
CrowdStrike is a computer security company, but we do not expect candidates for this role to have prior security industry experience. We will mentor and train in security topics as needed. We expect a strong interest in CrowdStrike's mission and a willingness to grow into a position consulting on system design decisions and coordinating with other teams across the company.
We want to talk if you have some but not all of the qualifications but bring a passion for cybersecurity.
What You’ll Do:
Develop test frameworks and test automation for developer use.
Design and write larger-scale integration and end-to-end tests.
Automate test processes for speed, reproducibility, and scalability. You will build unit tests, system tests, performance tests and more.
Understand the requirements of software projects and build test plans appropriate to those requirements.
Participate in reproducing and diagnosing customer support issues
Participate in end-to-end component design.
Write the tests that other engineers don't naturally own, like app compatibility.
Collaborate with multidisciplinary CrowdStrikers to improve our release validation process.
Identify needed test cases and coach developers on test development and coverage.
Evaluate features for risk, interior and exterior impact, and how we establish confidence.
Write clear and detailed bug reports when things break, and work with the team to identify and validate fixes.
Deliver and accept feedback with grace and courtesy.
What You’ll Need:
5+ years of hands-on SDET/test automation development experience.
Demonstrated experience with CI/CD frameworks.
Find bugs just as interesting as features; you like breaking software as much as building it.
Effective communication and collaboration to work well with a globally distributed team.
Experience with user and kernel debuggers (such as Windbg on Windows) and can diagnose a bug from a user or kernel crash dump.
Ability to program computers in a language used by the team (C, C++, Python) and can demonstrate that through job experience, schoolwork, or contributions to community projects.
Understanding of fundamental computer science concepts like compilation or thread contention.
Experience in the analysis and implementation of data structures, algorithms, and software design.
Experience testing databases, operating system services, or microservice architectures.
Experience building and using build pipelines, continuous integration, and test automation.
Passion for learning and championing the newest technologies & tricks with others to raise the technical IQ of the team.
Bonus Points:
Prior experience with pytest, Jenkins, or Bitbucket in a SAAS environment.
Prior experience working with low-level code, or Windows kernel development.
Knowledge of low-level operating system internals, components, APIs, and design, for one or more of our supported platforms (including Windows, macOS, and Linux).
Ability to read C++ code with a focus on robustness and security (or lack thereof).
Experience using performance profiling tools such as WPA, ETW, and Xperf for Windows.
Familiarity with embedded databases (LSM, RocksDB).
Familiarity with data modeling, design, and self-describing formats (like JSON).
Experience working with programming language tools or broadly distributed systems.
Experience with event processing systems.
Ability to improve developer experiences and workflows through automation, tooling, and testability.
