About Onebrief

Onebrief builds collaboration and AI-powered workflow software for military planning and operational coordination.

Military planning is complex by nature, requiring teams to coordinate information, people, and decisions across systems and locations. Onebrief brings planning, collaboration, simulation, and AI into one connected environment, helping teams test strategies, adapt to changing conditions, and make decisions with greater clarity when the stakes are real.

We are a distributed team of builders from military, operational, and technology backgrounds who care deeply about improving how important work gets done. Some team members work remotely, while others work directly alongside customers in operational environments around the world.

Founded in 2019, Onebrief is backed by leading investors including General Catalyst, Battery Ventures, Insight Partners, Sapphire Ventures, and Human Capital. Valued at more than $2 billion, we continue to invest in product innovation, AI capabilities, and team growth.

Why This Role Exists

As a Solutions Engineer at Onebrief, you work where mission, engineering, and compliance meet.

You'll own technical solution design and deployment readiness, translating customer requirements into secure, scalable deployment architectures. You'll partner with Platform Engineering, SRE, and our Cybersecurity team to validate infrastructure, configure environments, resolve technical blockers, and successfully transition solutions into production.

You’ll work with our go-to-market and customer facing teams to meet with planners, operations officers, and network owners to understand how they work today. You’ll help show them what that work looks like in Onebrief, and then you'll make it real.

You connect a staff's planning problem to a live, accredited Onebrief deployment.

What You'll Do

Core responsibilities:

• Run technical discovery. With Sales and Engineering, map a staff's current workflow and pain points, specifically focusing on their technical constraints: networks, hosting, identity, and integration requirements, especially in multi-network environments.
• Lead deployment engineering. Coordinate the technical delivery of new deployments, including infrastructure validation, network configuration checks, and system readiness verification. Write code to configure new deployments and support new environments.
• Support accreditation. Help create and review security documentation, including STIG checklists and ATO artifacts, alongside our cybersecurity team so deployments are accredited on the customer's timeline.
• Align stakeholders. Get technical stakeholders on both sides to agree on requirements, constraints, and tradeoffs, so customers see value sooner. Ensure those technical requirements are properly translated into contract deliverables.
• Scope integrations. Design how Onebrief Connect fits into a command's ecosystem: APIs, data pipelines, Foundry and Maven Smart System, CUOPS tools, and dashboards.
• Deliver tailored demos. Lead technical demonstrations and solution validation, partnering with Sales and customer-facing teams to demonstrate Onebrief's technical capabilities, deployment architecture, security posture, and integration options.
• Run pilot deployments. Configure Onebrief in new and untested environments to enable limited uses in support of new sales.
• Turn field experience into patterns. Convert what you learn in deployments into structured workflows and reusable implementation patterns, and feed clear requirements to Product and Engineering.
• Travel 30–50% of the time to customer sites and exercises.

• Strong expertise with containers (Docker) and orchestration (Kubernetes)
• Experience with cloud platforms (AWS, Azure, Google Cloud) and on-premises virtualization (RHEL)
• Solid understanding of networking concepts and protocols, and of security best practices for highly sensitive environments
