Role
Who you are
- You are a strategic engineer who translates complex Department of War (DoW) constraints into a cohesive technical roadmap
- You are a strategic planner who excels at technical roadmapping and can identify architectural gaps early, then build multi-quarter plans to address them before they become constraints
- You think in systems, looking beyond individual tickets to understand and redesign the underlying infrastructure
- When a pipeline fails, you focus on eliminating the class of failure rather than applying a temporary fix
- You take a pragmatic approach to technology decisions, knowing when to adopt new tools and when to invest further in proven systems
- You value long-term maintainability and operational clarity over short-term optimizations
- You lead by example, raising the technical bar through clear design documents, high-quality reviews, and mentorship on complex systems design
- 10+ years of hands-on experience building and scaling infrastructure systems
- 5+ years of experience in Platform Engineering, DevOps, or Site Reliability Engineering
- Proven experience leading organization-wide infrastructure initiatives and executing roadmaps aligned with business objectives
- Deep experience operating in highly regulated, secure, and/or air-gapped environments, including the Department of War or the Intelligence Community
- Expert-level knowledge of Kubernetes, including multi-cluster design, security, and the broader CNCF ecosystem
- Experience designing enterprise-grade infrastructure-as-code and automation frameworks using tools such as Terraform or Ansible
- Proficiency in Python and Bash for building custom tooling and automation
- Ability to communicate complex technical strategies to engineers and stakeholders and build alignment around long-term architectural decisions
- Willingness to obtain and maintain eligibility for a Top Secret clearance with SCI
What the job involves
- We are hiring a Principal Infrastructure Engineer to lead the next evolution of Onebrief’s infrastructure
- This role owns the long-term health, scalability, and technical direction of the platform
- You will look beyond the current delivery cycle to anticipate the infrastructure needs of mission-critical applications operating across multiple air-gapped environments
- Your work will enable product and engineering teams to deliver reliably across multiple classification levels with minimal friction
- Define and execute a one- to two-year technical vision for Onebrief’s infrastructure in partnership with engineering leadership
- Design and evolve a deployment strategy focused on AWS and on-prem environments, with support for partner-hosted deployments in other cloud platforms as required
- Build security and compliance directly into the infrastructure lifecycle through automation and policy-driven systems
- Identify and resolve the most complex technical debt and performance bottlenecks affecting the broader Product and Eengineering organizations
- Design and lead the implementation of the next generation of the Onebrief’s platform infrastructure
Our take
Onebrief is transforming military planning with its software platform, which simplifies and speeds up operational tasks for US military headquarters worldwide. The platform enhances decision-making and streamlines complex planning, supporting various missions from defense to humanitarian aid.
The company has continuously updated its offering, for example by launching an API for better integration with other military tools, and developing offline access for remote use. It has also added AI features as part of continued innovation to meet the evolving needs of military users.
Onebrief has secured substantial funding which has allowed it to grow significantly. The latest round, secured in early 2026, will support rapid scaling and comes alongside the company's acquisition of Battle Road Digital, a leading defense innovation company applying gaming technology to defense and national security challenges.
