Sr. SDET - Cloud, Detection Engineer (Hybrid, London)

As a global leader in cybersecurity, Crowd Strike protects the people, processes and technologies that drive modern organizations.

Since 2011, our mission hasn't changed - we're here to stop breaches, and we've redefined modern security with the world's most advanced AI-native platform.

We work on large scale distributed systems, processing almost 3 trillion events per day and this traffic is growing daily.

Our customers span all industries, and they count on Crowd Strike to keep their businesses running, their communities safe and their lives moving forward.

We're proud to work for a mission-driven company leveraging AI to transform the way we work.

Crowd Strikers drive their careers through flexibility and autonomy while also being expected to contribute to a culture of responsible AI adoption, experimentation, and innovation.

We use an AI-first mindset as a force multiplier to proactively and continuously accelerate execution, build expertise, uncover insights, and solve complex problems.

We're always looking to add talented Crowd Strikers to the team who have limitless passion, a relentless focus on innovation and a fanatical commitment to our customers, our community and each other.

Ready to join a mission that matters?

The future of cybersecurity starts with you.

We're building a welcoming & flexible team that prizes collaboration over competition, one which provides opportunities to learn new skills, mentor junior and senior developers and contribute to the direction of both the team & the products for which we're responsible.

This is a high trust environment where we allow team members to manage their own time, take holidays as they need it and reward them with competitive salaries and equity.

The Falcon endpoint agent is able to react in near-real-time to changes in the threat landscape, and underpinning this is the ability of the endpoint agent to quickly query our cloud for new information.

This system operates within tight latency and response time constraints at a scale matched by few other environments, and the scale is only growing.

Crowd Strike is seeking a Software Developer in Test for our Cloud Detections Platform team, which is tasked with building Crowd Strike’s next generation detection platform.

In this capacity, you will be in charge of developing and operating the team's CI/CD pipeline, making sure our solutions work, and raising the alarm when they suddenly don't.

You'll be building out an end-to-end validation pipeline, largely from scratch, leveraging existing frameworks and tooling where possible, but able to color outside the lines when necessary.

You'll work in an environment where quality is the company culture.

Come use cutting edge tools and technologies as well as tried and true ones.

Work on: verifying key features and functionality that spans our processing, data and customer facing application layers to ensure it's able to support low-latency prevention of malware, manage tens of thousands of events per second, query across terabytes of data and support the team in delivering quality code, tested to perfection.

What You'll Do

• Verify component, system integration and application level features and functionality to ensure our reliability, accuracy and performance reaches our standards for quality.
• Participate in code and design reviews and provide technical guidance and feedback to team members.
• Review engineering technical design documents and requirements.
• Provide guidance and strategy about how and where to build in testability.
• Engage in continuous improvement of our end-to-end test and validation processes.
• Increase and improve our automated test coverage, and contribute to existing tools, frameworks and related solutions.
• Leverage new open source solutions to build new tools that test things in new ways.
• Improve our delivered product quality across our entire platform and applications.
• Collaborate on determining root causes of production outages and adding quality improvements to prevent outages in the future.
• Crowdstrike is a remote-friendly company, but we do get together from time to time. Some travel will be required for in-person meetings.
• Build and manage CI/CD pipelines using Jenkins, Github actions or similar tools.
• What You'll Need
• 10 + years of experience as an SDET or Backend Developer (combined)
• 4-5 + years building testing frameworks and tooling for a Cloud Saa S product
• Strong debugging skills: ability to spot design flaws, race conditions and performance bottlenecks in complex architectures.
• A computer science background or equivalent experience (programming styles, data structures, algorithms, etc.)
• Experience in building, validating, and/or maintaining large distributed systems at scale.
• Solid design and problem-solving skills with a demonstrated passion for engineering excellence, quality, security, and performance, coupled with a desire to ship elegant solutions to complex problems.
• Strong cross-group collaboration and interpersonal communication skills working across engineering organizations.
• Experience with Golang, Python, Kubernetes, Cassandra, Redis, Kafka, Elastic Search, Python, and/or similar technologies. You don’t need all of these, but you need at least one.
• Both a sense of humor and a sense of humility.
• Bonus Points
• Prior experience with building, operating, validating, and scaling low-latency internet services.
• Experience with building and shipping cloud-connected endpoint software.
• Solid grounding in the technology of at least one cloud environment (AWS, Azure, GCP).
• Exposure to/experience with cybersecurity and intelligence.

Crowd Strike was founded in 2011 to fix a fundamental problem: The sophisticated attacks that were forcing the world’s leading businesses into the headlines could not be solved with existing malware-based defenses.

Founder George Kurtz realized that a brand new approach was needed - one that combines the most advanced endpoint protection with expert intelligence to pinpoint the adversaries perpetrating the attacks, not just the malware.

There’s much more to the story of how Falcon has redefined endpoint protection but there’s only one thing to remember about Crowd

Strike: We stop breaches.
