Sr. Engineer, Backend - Lightning (Hybrid)

About the role

Crowdstrike Falcon Platform's 'Lightning' suite is a suite of services in the CrowdStrike cloud that expose sub-second, near-real-time APIs enabling Falcon Sensors to rapidly obtain threat information. Operating at massive scale, Lightning processes trillions of threat events daily within tight latency constraints - where performance and availability are critical to sensor operation and customer protection. The Lightning Team is seeking a Senior Software Developer (commonly translates to 'Staff/Sr Staff' titles in other companies). This product is 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 building high-quality systems that scale cleanly and reliably, primarily in Go (and also some Python). We're involved across the entire product line and you'll work closely with other groups across the company. This role is hybrid, requiring 2-3 days per week on-site in one of the posted locations. This is a welcoming and flexible team that prizes collaboration over competition, providing opportunities to learn new skills, mentor developers at all levels, and contribute to the direction of both the team and its products. This is a high trust environment where team members manage their own time, take time off as needed, and are rewarded with competitive salaries and equity.

Responsibilities

• 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.

Requirements

• A computer science background or equivalent experience (programming styles, data structures, algorithms, distributed systems, etc.) with at least 5(+) years building backend systems in a SaaS, cloud platform or other SOA.
• 8+ years (Avg: 10-15+) of experience building and scaling back-end systems in production.
• Expertise in any of: Golang, Python, Java, Kotlin, Scala
• Strong experience in a cloud distributed systems stack: i.e. Kubernetes, Cassandra, Redis, Kafka, Elastic Search, and/or similar technologies. You don't need all of these specifically, but transferrable skills in each category are a must.
• Deep understanding of distributed systems and scalability challenges.
• Prior experience with cloud services, such as AWS or Azure, particularly compute and storage offerings.
• Team player skills - we embrace collaboration.
• 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 co
