About The Role

Our Senior 1 title at Crowdstrike is often equivalent to Staff-to-Principal titles elsewhere in scope, impact and overall technical challenge. This role is for an experienced leader of major initiatives accustomed to owning their services/designs soup to nuts/end to end both in aspects of design through implementation, as well as in terms of operational ownership (i.e. "you build it, you run it"). You’ll be joining the cloud backend team in the Platform product group responsible for authentication and authorization. The Auth team is responsible for both internal (e.g. Service-to-service authorization, etc.) and external (e.g. user login, etc) authN and authZ. The team is a critical part of our flagship product group supporting the Falcon Platform, frequently working collaboratively with many other product groups. The team builds and extends services that are capable of making millions of decisions per second (most recently benchmarked at 19 million TPS)!

What You’ll Do

Lead backend engineering efforts from rapid prototypes to large-scale applications across CrowdStrike products.
Leverage and build cloud based systems to detect targeted attacks and automate cyber threat intelligence production at a global scale.
Brainstorm, define, and build collaboratively with members across multiple teams.
Obsess about learning, and champion the newest technologies & tricks with others, raising the technical IQ of the team.
Be mentored and mentor other developers on web, backend and data storage technologies and our system.
Constantly re-evaluate our product to improve architecture, knowledge models, user experience, performance and stability.
Be an energetic ‘self-starter’ with the ability to take ownership and be accountable for deliverables.
Use and give back to the open source community.
