Principal DevOps Engineer

Summary

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. The employee will shape cloud strategy, influence technical direction, resolve complex challenges, and mentor engineers across the organization. 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.”

Required Education and Experience

• BS/BA in Computer Science, Engineering, or related field.
• 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 Foundry, Azure APIM.
• Relevant certifications (e.g., AZ-305, AZ-400, CISSP) are a plus.
• Experience developing and solutioning for common compliance frameworks, such as FedRAMP, DoD IL4, SOC, SOX.

Knowledge, Skills, and Abilities
