Role

Who you are

12+ years of experience, including ownership of meaningful product or platform surfaces
Experience driving technical direction across teams, laying foundations that scale beyond a single team
Proven track record of shipping in demanding B2B SaaS environments
Ability to thrive in ambiguous, low-process, async-first settings and bring clarity and composure during high-impact situations
Hands-on contributor who improves velocity and raises engineering standards through tooling, process, and direct execution
Strong communication skills, with the ability to communicate clearly and contextually across PRs, RFCs, and cross-functional collaboration

What the job involves

We're hiring Staff Software Engineers to take on some of the most challenging and meaningful full-stack problems at Onebrief; the kind that sit at the intersection of system design, product complexity, and real-world stakes
Think: real-time collaboration infra, interactive planning UIs, and high-trust workflows that operate under real constraints. We value strong problem-solving skills and sound engineering judgment over mastery of any one technology
This is a staff individual contributor role with broad surface area. Expect to own big bets, shape direction, unblock teams, and raise the bar for how we build
You’ll partner tightly with Product Managers, Design, and your fellow engineers. By developing reusable patterns, sharing thoughtful abstractions, and communicating clearly, the impact of your work will span across teams
Lead complex, multi-sprint initiatives that span teams and require both technical depth and strong product intuition
Set technical direction across user-facing and platform surfaces, shaping architecture beyond a single team
Improve system quality and developer experience by identifying systemic pain points and building durable abstractions
Operate comfortably in high ambiguity, bringing clarity to grey areas and aligning stakeholders on thoughtful tradeoffs
Mentor and elevate engineers through async reviews, pairing, and principled technical leadership
Build across the stack (TypeScript/React/Node, PostgreSQL, Redis, Kubernetes), balancing long-term architecture with pragmatic delivery

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.
