Job Description:

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. We have 3.44 PB of RAM deployed across our fleet of C* servers - 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 also a mission-driven company. We cultivate a culture that gives every CrowdStriker both the flexibility and autonomy to own their careers. 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:

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.

CrowdStrike is seeking a Senior Software Developer, Backend for our Detections Platform team. This role is part of a team responsible for the cloud services that provide security information to the endpoint agent in near-real-time. The services that store this information aren't always near-real-time themselves, so we use a variety of strategies for caching, backpressure, and partial responses. You'll be thinking about how to build high-quality systems that scale cleanly and reliably, and then implementing those ideas primarily in Go (and also some Python). Detections Platform is involved across the entire product line and you'll work closely with other groups across the company. You'll also be working in an environment where quality is the company culture.

CrowdStrike is a computer security company, but we do not require candidates for this role to have prior security industry experience. We will mentor and train in security topics as needed. We do expect a strong interest in CrowdStrike's mission and a willingness to engage with the needs of our product teams and customers.

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.

What You'll Do:

• Build and evolve cloud-based systems to detect and disrupt targeted attacks at a global scale.
• Brainstorm, design, and build collaboratively with members across multiple teams.
• Build elegant and performant solutions for complex technical problems in Go.
• Read and critique code in the multiple programming languages in use in our environment (Go, Python, Unix shell, among others), and provide technical guidance and feedback to team members
• Focus on continual learning, raising the bar for both yourself and your teammates.
• Leverage our understanding of engineering best practices, including topics like appropriate testing paradigms, effective peer code reviews, logging, and resilient architecture patterns, to ensure that our code is clean.
• Be an energetic 'self-starter' with the ability to take ownership and be accountable for deliverables, both individually and when leading a team.
• Deliver and accept feedback with grace and courtesy.
• 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.

What You'll Need:

• A computer science background or equivalent experience (programming styles, data structures, algorithms, distributed systems, etc.)
• 8+ years of experience building and scaling back-end systems in production.
• Team player skills - we embrace collaboration.
• Deep understanding of distributed systems and scalability challenges.
• 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 some.
• Prior experience with cloud services, such as AWS or Azure, particularly compute and storage offerings.
• Experience developing and deploying into Linux.
• 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.
• Prior experience working within scalable microservices architectures.
• Prior experience with containerization and container orchestration technology such as docker and Kubernetes.
• Exposure to/experience with cybersecurity and intelligence.
