Company mission

Role
Who you are
- 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
- 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
- Experience 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
- This position requires the ability to obtain a U.S. security clearance, which is only available to U.S. citizens
What the job involves
- We’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
- Set 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
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.
