Principal Cloud DevOps Engineer

OneStream Software is a hyper-growth SaaS company focused on financial and operational data analytics for the world’s largest companies. We host our software on Microsoft Azure across regions worldwide. This Principal-level role provides technical leadership in designing and automating scalable, secure cloud environments.

This role partners across teams to drive reliable, efficient cloud operations at scale. 

Primary Duties and Responsibilities 

• Own technical strategy and multi-quarter roadmaps across Cloud Engineering’s core domains (CI/CD, IaC, containers/AKS, observability, security).
• Represent Cloud Engineering in cross-functional and leadership forums, partnering with Product, Security, Compliance, Platform, and QE.
• Lead complex, multi-quarter initiatives spanning departments and engineering teams, driving alignment, adoption, and delivery.
• Serve as the escalation point for the most complex production issues and drive resolution of systemic technical debt.
• Mentor engineers and scale technical leadership and standards without relying on direct authority.
• Designing optimal solutions that take into consideration the ideal technical implementation while balancing the financial impacts to the organization.
• Own the Terraform codebase end to end: module design and versioning, remote state strategy on Azure Storage backends, state-splitting by lifecycle/ownership, and drift detection.
• Embed security-as-code: managed identities and workload identity federation by default, Key Vault integration, RBAC and Azure Policy defined as Terraform resources, and container image scanning via ACR / Defender for Containers.
• Design for reliability: multi-region failover (Traffic Manager / Front Door), backup and disaster recovery (Azure Backup, paired regions), observability (Azure Monitor, Log Analytics, Application Insights), as well as partner with development and business on SLO/error-budget definition.
• Design reusable, versioned Terraform modules and AKS blueprints that other engineering teams can self-serve our “paved road.”

• 10+ years of hands-on experience in cloud infrastructure, DevOps, or platform engineering, including IaC (Terraform/Bicep), CI/CD & GitOps, and cloud architecture (Azure preferred).
• Demonstrated experience owning technical strategy and driving org-wide standards, not just team-level delivery.
• Proven transformative impact on improving developer experience.
• Deep understanding of the Azure Well Architected Framework. 

Preferred Education and Experience 

• Experience at a cloud service provider, managed service provider, or SaaS company.
• Experience shaping cloud-native strategy at scale, such as the Kubernetes/AKS platform, Azure SQL, AI Foundary, Azure APIM.
• Relevant certifications (e.g., AZ-305, AZ-400, CISSP) are a plus.
