Role

Who you are

12+ years of experience as a Software Engineer, including owning meaningful product or platform surfaces
Systems thinking and pragmatic architectural judgment, especially in complex environments
A track record of shipping in B2B SaaS or similarly demanding domains
Clear, context-rich communication across PRs, RFCs, and collaborative docs
Comfort navigating ambiguity and low-process, async environments
Hands-on experience improving team velocity via tooling or process improvements

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
This is a senior IC role with broad surface area
Expect to own big bets, shaping direction, unblock teams, and raising the bar for how we build
You’ll partner tightly with PM, Design, and your fellow engineers
Your work will ripple across teams via reusable patterns, thoughtful abstractions, and crisp communication
Lead multi-sprint initiatives that require both technical depth and product intuition, especially in user-facing surfaces
Improve system quality and dev experience by cleaning up pain points, building durable abstractions, and elevating our internal tools
Drive technical direction within your team, while contributing to architecture across adjacent systems
Support and unblock peers through async reviews, pairing, and mentorship
Work in an async-first way, aligning clearly on scope, tradeoffs, and outcomes
Build across the stack, using TypeScript/React/Node with PostgreSQL, Redis, and Kubernetes under the hood
Frontend: React, TypeScript, Vite, shared component libraries, client-side observability
Backend: Node.js, PostgreSQL, Redis, secure RESTful APIs
Infrastructure: Kubernetes, AWS, CI/CD pipelines
Integrations: CSV/Excel/KML importers, JWT auth, PDF exports, DoD data systems

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.
