As a global leader in cybersecurity, CrowdStrike 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 CrowdStrike 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. CrowdStrikers 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 CrowdStrikers 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.

About the Role:

We're building the next-generation infrastructure and security platform for CrowdStrike. The OverWatch Labs (OWL) team builds the platform and tools for our analysts on the OverWatch team to process and hunt (identify potentially harmful activity) through trillions of events per day, and growing. 

We are looking for an engineer who wants to help move the OWL platform forward as we scale even further. Someone with a broad range of computer skills throughout the software stack and clear communication skills would thrive in this environment. You should love working on large-scale, distributed, cloud-based, highly available systems that can efficiently operate over trillions of events per day. 

Team Culture 

Stay humble. Stay positive. Stay hungry. 

• Exhaustively passionate: We can’t emphasize this enough. We love what we do, and feel our work is making a notable impact and difference on a global and geopolitical scale.
• Strong work ethic: We work extremely hard, not just smart. It’s essential to our success. Be ready to be dedicated and focused. 
• Team player: Our success and failures are shared together. We learn from each other. We help each other to grow and develop. We take constructive criticism gracefully and give credit where credit is due. 
• Learner: Be willing to learn, to seek truth, and understanding. Take the initiative to acquire knowledge and investigate questions you might have. 
• Adaptable/Agile/Flexible: Nothing ever goes according to plan, be prepared to do any task necessary that benefits and contributes to the team success (i.e. low-level data entry to high-level research design and experimentation) 

We are looking for an engineer to work on building and maintaining scalable data infrastructure/platforms and tools for our team. Someone with foundational knowledge in algorithms, software engineering/development and operational research is highly preferred and proven experience utilizing AI technologies to enhance decision-making, streamline workflows and processes, improve efficiency and drive business outcomes. In short, someone who has the technical groundwork, ready to gain experience and communicates well with others. 

What You'll Do:

• Collaborate with OverWatch engineering members to build, develop, and maintain operational systems, projects, and tools. 
• Be comfortable with projects to build new components and extend the current system. ● Help the OverWatch team become more effective in their analysis and hunting by improving the platform and tools. 
• Bring research projects into production environments and integrate them with the OWL systems. 
• Work in a devops environment where you (and your team) are responsible for the systems you deploy. This will involve an on-call rota.
• Be an energetic ‘self-starter’ with the ability to take ownership and be accountable for deliverables. 
• Have a desire for quality and understand what tools and processes you need to reach that level and help the team reach a higher bar. 
• Be an adaptable and flexible engineer who is constantly learning and enjoys tackling complex and novel challenges. 
• Use and give back to the open source community. 
• Work as part of a distributed team of remote workers across timezones.

You'll use… 

• Go (Golang) 
• Python 
• AWS 
• Postgres 
• ElasticSearch 
• Kafka 
• Kubernetes 
• Many external and internal APIs 

What You'll Need:

• Degree in Computer Science (or commensurate experience). 
• Experience with Golang or another language for developing web backends and pipelines (such as Python/Ruby/etc) or compiled languages like Rust or C++. 
• Built web-services with data processing pipelines and the concepts required. ● Experience with relational and noSQL databases (Redis, Postgres, Cassandra, ElasticSearch a plus). 
• Understanding of messaging or queueing software, Kafka experience helpful but not required. 
• Linux skills and experience with large-scale, business-critical Linux environments.
• Understanding of distributed systems and scalability challenges, particularly in Cloud environments such as AWS. 
• The ability to thrive in a fast paced, test-driven, collaborative and iterative programming environment. 
• A thorough understanding of engineering best practices from appropriate testing paradigms to effective peer code reviews and resilient architecture. 

Bonus Points:

• Authored and led successful open source libraries and projects. 
• Contributions to the open source community (GitHub, Stack Overflow, blogging).
• Existing exposure to Go, AWS, Cassandra, Kafka, Elasticsearch... 
• Prior experience in the cybersecurity or intelligence fields. 

Bring your experience in distributed technologies and algorithms, your great API and systems design sensibilities, and your passion for writing code that performs at extreme scale. You will help build a

platform that scales to millions of events per second and Terabytes of data per day. If you want a job that makes a difference in the world and operates at high scale, you’ve come to the right place.
