Software Engineer III, Core Services & Libraries (Remote, AUS)

Responsibilities

• 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

Requirements

• 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 migrat

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.
