Staff Software Engineer, Full-stack

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.

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

• ~6 - 10+ 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

• 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
