About The Product

CrowdStrike Falcon 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 behaviour, then provides on-box prevention capability and remote telemetry to the Falcon cloud. The cloud component aggregates sensor telemetry for each customer’s network, can correlate malicious behaviour across multiple machines, and presents our customers’ operations teams with a prioritized summary of the threats detected in their environments.

About The Role

This is a Senior Software Development Engineer (SDE) role in the engineering team that delivers the sensor (lightweight agent) on Linux. This role will be part of the team designing and implementing new features in the sensor to secure cloud workloads. The work leverages eBPF and other technologies. These features will extend the power of the Falcon platform to provide seamless visibility, detection, and prevention for container processes running in orchestration environments like Kubernetes.

SDE’s in the team own design and development of core features of the product. Features will cross-cut most core OS subsystems such as file system, memory, process, and networking. The team operates under the Agile development principles and ships frequently.

What You'll Do

• Design and develop Linux software for deployment on server
• Own features from design to delivery
• Collaborate with multi-functional team in various physical locations
• Troubleshoot issues with the product as reported from customers responsively
• Other projects as assigned

What You'll Need

• 8+ Years of relevant experience.
• Experience working on product features on Linux or Unix in C/C++ with the following characteristics:
• high concurrency requirements needing strong use of multi-threading
• high reliability requirements
• detailed requirements on low-level operating characteristics (memory usage, efficient performance, correct conformance to external standards)
• Experience developing production eBPF code for security or networking
• Experience designing and developing container runtime engines, software that monitors containers. or optimized virtual machine environments to run containers.
• Experience working on a team to ship major features and releases
• Ability to communicate, collaborate, and work effectively in a distributed team

Role & Responsibilities:

• Networking solutions development, platform tuning, optimization, and competitive benchmarking.
