Why This Job is Featured on The SaaS Jobs
This senior engineering role sits in a part of SaaS that is often invisible to customers but decisive for product reliability: the shared services, libraries, and platform primitives that many internal teams build on. In an AI-native cybersecurity platform, those foundations tend to be exercised under real production pressure, where consistency, secure defaults, and clear abstractions determine how quickly the wider organization can ship and how safely it can operate.
For a long-term SaaS career, work at the core-services layer compounds. It builds durable expertise in API design, backward compatibility, and operational resilience, all of which translate across SaaS companies with microservice architectures. The remit also touches multi-cloud portability, observability, and dependency security, giving exposure to the cross-cutting concerns that shape platform strategy and influence engineering standards beyond a single product area.
This role is best suited to engineers who prefer leverage over feature ownership, and who enjoy building tools other engineers choose to adopt. It favors a working style that balances design governance with hands-on production accountability, including on-call and incident learning. It also fits professionals who want to be a technical reference point across teams rather than staying within one service boundary.

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. 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 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
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
