Ready to join a mission that matters? The future of cybersecurity starts with you.

About this role:

The Core Services & Libraries team builds and owns the shared Go libraries and platform capabilities that CrowdStrike's engineering organization runs on. If an engineer needs to talk to a data store, publish a message, make a service call, manage feature rollouts, or handle failures gracefully — they reach for something this team built.

You'll own foundational software that has to be right: well-designed APIs that tens of teams adopt, resilience patterns that hold up under real-world failure, and cloud abstractions that let services deploy anywhere without caring where. The scope is broad and growing — spanning data access, messaging, service communication, multi-cloud portability, observability, and security — with plans to extend beyond Go into other language ecosystems.

What You’ll Do:

• Build and own shared libraries that engineers across the company depend on for data access, messaging, service communication, observability, and resilience

• Design APIs that get adopted — your interfaces need to be good enough that teams choose them over building their own; that means thoughtful defaults, clean abstractions, backward compatibility, and strong documentation

• Build multi-cloud abstractions that let services run across cloud providers and on-premise environments without vendor-specific code

• Design and implement resilience patterns — retries, circuit breakers, load shedding, graceful degradation — as reusable primitives that become the default for every service

• Build platform capabilities — feature management, traffic control, disaster recovery, and sharding as composable libraries

• Own the security posture of shared dependencies — keep foundational libraries current, remediate vulnerabilities, and ship secure defaults

• Participate in architectural governance — propose, review, and shepherd RFCs that set direction for the services ecosystem

• Advocate and consult — be a trusted advisor to engineering teams adopting shared libraries; help them make the right architectural choices, unblock integration challenges, and feed their needs back into the platform

• Partner with Data Services, Infrastructure, SRE, and Observability — your libraries sit on top of their platforms; build strong working relationships that keep shared libraries aligned with operational reality

• Operate what you build — on-call rotations, production triage, and using operational insight to make the libraries better

What You’ll Need:

• Strong Go expertise — you've built production libraries or frameworks, or have deep experience designing APIs and abstractions consumed by other engineering teams

• Distributed systems depth — hands-on experience with message brokers, data stores, service communication frameworks, and the failure modes that come with distributed architectures

• Library and API design sensibility — you understand backward compatibility, versioning, migration paths, and what makes an API that developers actually want to use

• Cloud infrastructure experience — meaningful experience with at least one major cloud provider, ideally including multi-region or multi-cloud patterns

• Operational maturity — you've owned production reliability for systems you've built, debugged incidents under pressure, and turned those experiences into improvements

• 5+ years of software engineering experience, with meaningful time in platform, infrastructure, or developer tools

• Proven experience utilizing AI technologies to enhance decision-making, streamline workflows and processes, improve efficiency and drive business outcomes.

Bonus Qualifications:

• Experience building or contributing to widely-adopted open source libraries

• Background in developer experience — migration tooling, documentation, developer portals

• Cost-conscious engineering — understanding how library defaults affect infrastructure spend at scale

• Deep knowledge of messaging system internals — consumer groups, partition strategies, delivery guarantees

• Multi-cloud migration experience — abstracting vendor-specific APIs behind clean interfaces

• Observability expertise — distributed tracing, metrics pipelines, structured logging

• Experience designing resilience primitives — rate limiting, circuit breakers, load shedding, retry budgets

• Experience with large-scale SDK migrations or safe deprecation of widely-used libraries
