Onebrief is collaboration and AI-powered workflow software designed specifically for military staffs. By transforming this work, Onebrief makes the staff as a whole superhuman - meaning faster, smarter, and more efficient.
We take ownership, seek excellence, and play to win with the seriousness and camaraderie of an Olympic team. Onebrief operates as an all-remote company, though many of our employees work alongside our customers at military commands around the world.
Founded in 2019 by a group of experienced planners, today, Onebrief’s team spans veterans from all forces and global organizations, and technologists from leading-edge software companies. We’ve raised $123m+ from top-tier investors, including Battery Ventures, General Catalyst, Insight Partners, and Human Capital, and today, Onebrief is valued at $1.1B. With this continued growth, Onebrief is able to make an impact where it matters most.
About the RoleWe’re hiring a Director of Engineering to lead our Backend Platform org, which includes our Data Platform, Third party API & Data Integrations, and Applied AI teams. This is a foundational role; you’ll work with product to set the vision, guide the people and systems behind how we store data, move information, and power smart workflows across our product.
You’ll report to the VP of Engineering and work closely with leaders across Product, Design, and Infrastructure. The scope here is broad: organizational and technical, near-term and strategic. We’re looking for someone who thrives at the system level. Someone who sees platforms not just as architecture, but as leverage for the entire company.
What You’ll DoSet direction and connect the dots. Shape the vision across data, APIs, and AI enablement, then work with your teams to turn that vision into focused, sequenced initiatives.
Support and scale great teams. Initially, you’ll lead 3 Engineering Managers (and their teams of ~8 engineers), helping them grow, navigate ambiguity, and scale.
Invest in technical quality. Make sure our backend systems are observable, secure, performant, and cost-aware. Raise the bar on architecture without slowing down delivery.
Collaborate deeply. Work closely with PM, Design, and other Engineering leaders to shape quarterly plans, align technical work with real user outcomes, and unblock cross-team delivery.
Make systems better over time. Lead the evolution of our service architecture, cloud infra, and AI foundations. Balance speed with sound engineering judgment.
Build a healthy culture. Model low-ego, context-rich leadership. Create rituals that help teams plan, reflect, and work asynchronously while delivering value and maintaining healthy work life boundaries.
You build a team of leaders, not followers. You’ve built and led platform teams before, in fast-moving, and rapidly growing product companies. You care about systems that last and teams that grow with clarity. You’re comfortable zooming between strategic tradeoffs and technical details. You believe in building trust through presence, not control.
QualificationsLeadership & org-buildingExperience leading managers in backend or platform teams
10+ years of engineering experience, with significant depth in backend or infrastructure domains
Experience growing teams in a rapid growth environment, mentoring EMs, and designing org structures that support autonomy and focus
Clear communicator across functions and async-first teams
Strong grasp of backend platforms: Node.js, Postgres, Redis, Kubernetes, AWS
Experience with data pipelines, secure ingestion, API ecosystems, and system design at scale
Familiarity with observability, cost optimization, and reliability patterns
Bonus: experience enabling AI/ML teams or building infra for LLM-powered features
History of driving multi-quarter platform roadmaps in product-led companies
Comfort shaping team scopes, defining SLAs, and guiding technical standards
Ability to translate complexity into clarity, and align cross-functional teams around the work that matters
We build planning tools for military staffs, replacing brittle, legacy workflows with modern, real-time software. Our product is used in classified environments, often in moments that truly matter. That means our infrastructure needs to be trustworthy, scalable, and invisible when it works.
We’re a mission-driven team with strong product instincts and a bias toward clarity. We are deployed across COCOMs and Joint Staff, and are still small enough for each new leader to shape how we scale.
If this role sounds like a fit, or you’re curious to learn more, we’d love to meet you.

What We Do
Before Onebrief, military planning and collaboration was slow, inefficient, and resource-intensive. Building slides with no version control as partners collaborated would have staffs spend weeks or months on a single product or document.
With Onebrief, these workflows are now simple and collaboration between large commands is efficient. Staff optimization is the key to building a more resilient, more effective military. Today Onebrief users report at least 2x time savings - and growing.
Onebrief is a first of its kind software for the military. While many others have tried to build a solution for this problem, Onebrief’s “card” structure for reusing data and enabling real time updates is what makes this possible. Core features and attributes that make this platform powerful include:
- Global Collaboration
- Real-Time Updates
- AI Automation
- Interoperability + Integrations
- Deployable across Secret and Top Secret Networks
Mission Driven
Onebrief is composed of professionals from backgrounds of all kinds - spanning veterans across forces and organizations, and technologists from leading-edge software giants.
Onebrief is more than just a software platform; it's a mission-driven company dedicated to improving the efficiency and effectiveness of military planning. By joining the team, you'll contribute to solutions that directly support national security and the work of service members.
Your work directly addresses critical challenges that military planners and operators face daily. Every line of code and every design decision contributes to real-world outcomes.
The software was designed and built by a team of experienced planners - lending a nuanced perspective on the challenges our partners face. Our team embeds alongside users - from
the Pentagon to the Indo-Pacific - to build a platform that meets their unique needs.
Rapid, Strategic Growth
Our users love the platform and growth is scaling, most recently reporting operational usage growth at a 19,600% annualized rate. Stronger utilization is underway and we’re at an exciting period of advancement.
As a rapidly growing organization, you'll directly influence its direction and long-term success. Over the past year we’ve seen exciting growth metrics:
First, our headcount has grown 150% YoY to keep pace with our product advancement and customer growth.
