Software Development Engineer in Test - Linux
CrowdStrike (www.crowdstrike.com) is a computer security company founded on the principle that effective computer security cannot be achieved without understanding the goals, tactics, and techniques used by determined attackers who can be expected to purposefully and repeatedly pursue their objectives to the detriment of our customers.
CrowdStrike Falcon Host is a two-component security product. One component is a “sensor”, which is a lightweight agent installed on client machines that observes system activity and recognizes malicious behavior, then provides on-box prevention capability and remote telemetry to the Falcon Host cloud. The cloud component aggregates sensor telemetry for each customer’s network, can correlate malicious behavior across multiple machines, and presents our customers’ operations teams with a prioritized summary of the threats detected in their environments.
This is a Software Development Engineer in Test (SDET) position in the sensor engineering team. At CrowdStrike, SDETs and SDEs work together in combined engineering teams. SDETs are key contributors in the team’s focus on quality of the sensor.
Here are the quality-focused tasks in the team that SDETs are heavily involved in:
- Analyze complex software features, and build effective test strategies and test design.
- Build useful tools, frameworks, and test setup to use for developing tests effectively; the goal is to minimize manual testing and for the team to write automated tests for the product.
- 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.
SDETs use their strong software development skills to build effective tools, harnesses, and specialized tests to assure that quality. SDETs also participate actively in design and code reviews, and collaborate with the cloud team to assure end-to-end system functionality.
The ideal SDET candidate must have demonstrated passion to find bugs -- i.e. they must like breaking software as much as writing code! They also must have demonstrated ability to write high-quality code in C or C++ and scripting languages like Python. Experience on Unix or Linux with code that has high reliability requirements; code that needs to pay attention to low-level operating characteristics (memory usage, efficient performance, correct conformance to external standards) is also highly desired.
Though the following are not all required for this position at the outset, strong SDETs in the team eventually build the following skills:
- Deeper understanding of fundamental computer science concepts; experience in analysis and implementation of data structures, algorithms, and software design
- Ability to write and automate test cases, triage bugs, and write actionable bug reports
- Ability to read code with a focus on its robustness and security (or lack thereof)
- Ability to clearly define test strategies for features, and implement those strategies
- A track record of shipping quality software
The team provides strong mentoring and management support to develop these skills while working on their core deliverables. SDETs also have the opportunity, along with SDEs, to learn more about the tools, techniques, and procedures employed in attacks on our customers and to use this knowledge in challenging the entire team to constantly improve Falcon’s capabilities.
