About the Role:

CrowdStrike is seeking a Senior Software Engineer to help design and build the software systems that power our global LogScale/NG-SIEM infrastructure footprint. The FrontTier Expansions team is responsible for enabling LogScale fleets to run reliably wherever our customers need them — across AWS, GCP, OCI, and CrowdStrike-managed datacenters. As a senior engineer, you'll take ownership of core services and automation frameworks that make multi-cloud expansion fast, safe, and repeatable, while mentoring others and raising the engineering bar across the team.

You'll be building software for systems that ingest over 100 PB of event data daily, support decade-long data retention, serve millions of queries per hour, and support thousands of customers globally. This is an opportunity to write code that operates at a scale few engineers ever experience, where your contributions directly impact the security posture of organizations worldwide.

This role is hybrid, requiring 2-3 days per week on-site from our Austin, TX Office.

What You'll Do:

• Design, build, and own core services and libraries that support multi-cloud deployment and operation of LogScale fleets across AWS, GCP, OCI, and on-prem datacenters
• Develop automation tooling and microservices that standardize how infrastructure and platform components are provisioned, upgraded, and scaled across cloud providers
• Build and extend observability tooling — tracing, profiling, alerting, and SLO frameworks — to give the team proactive insight into fleet health at scale
• Architect solutions for capacity planning, workload forecasting, and dynamic scaling across heterogeneous cloud environments
• Contribute to and improve shared-tier libraries and frameworks used across the broader NG-SIEM/LogScale platform
• Drive technical design for version upgrades, patch orchestration, and configuration management systems that minimize customer impact
• Implement security-first infrastructure designs — including authentication, authorization, encryption, and audit logging — aligned with cybersecurity industry standards and compliance requirements
• Adopt GitOps methodologies and DevSecOps best practices within CI/CD pipelines
• Act as a technical lead and liaison between FrontTier Expansions and internal stakeholders on infrastructure and platform capabilities
• Design, deploy, and troubleshoot services running in Kubernetes clusters across managed and self-managed environments
• Mentor engineers on distributed systems design, cloud architecture, and engineering best practices
• Evangelize best practices for building reliable, scalable software, and raise the technical bar of the team
• Participate in an on-call rotation supporting production infrastructure globally
• Continuously re-evaluate architecture, performance, and reliability as the platform scales to new clouds and customers

What You'll Need:

• 7+ years (avg. experience = 10-15 yrs) of full-time experience in a service-oriented backend developer role
• 5+ recent years developing microservices for a SaaS product in Go, Python, or similar object-oriented/backend language
• Strong software engineering fundamentals (data structures, algorithms, distributed systems)
• Hands-on experience with at least one major cloud provider (AWS, GCP, or OCI), with strong eagerness and ability to learn others
• Deep understanding of distributed systems, scalability challenges, and multi-threading/concurrency concepts
• Experience designing and building microservices, automation tooling, or infrastructure-as-code frameworks for production systems
• Experience deploying, operating, and troubleshooting applications in Kubernetes clusters in production
• Experience with configuration management/IaC tooling (Chef, Ansible, Terraform, or similar)
• Experience with CI/CD tooling (Jenkins, Git, Artifactory, Bitbucket, or similar)
• Solid understanding of networking concepts (VPCs, load balancers, DNS)
• Understanding of security-first design principles: authentication, authorization, encryption, and audit logging
• A thorough understanding of engineering best practices — testing paradigms, code review, and resilient architecture
• Proven ability to mentor other engineers and raise the technical bar of a team
• Strong communication skills and proven ability to collaborate effectively with distributed, cross-functional teams across time zones
• A self-starter mentality with the ability to own problems end-to-end and drive them to resolution
• Availability for on-call on a rotational basis
• Proven experience utilizing AI technologies to enhance decision-making, streamline workflows and processes, improve efficiency and drive business outcomes.

Bonus Points:

• Expert-level Go; experience with multiple cloud platforms (AWS, GCP, OCI, Azure)
• LogScale/Humio, Kafka, or other distributed streaming/log management systems
• Experience with data lake/lakehouse architectures or data federation at scale
• Kubernetes operators/Helm development or CKA/CKAD/CKS certification
• SRE practices (SLOs, error budgets) and observability tooling (Prometheus, Grafana, Datadog)
• Cloud certifications (AWS/GCP/OCI) and FinOps/cost optimization experience
• Open source contributions; effective use of AI coding assistants
• CS degree (or commensurate experience); cybersecurity/SIEM background
