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 $320m+ from top-tier investors, including Battery Ventures, General Catalyst, Sapphire Ventures, Insight Partners, and Human Capital, and today, Onebrief is valued at $2.15B. With this continued growth, Onebrief is able to make an impact where it matters most.
About the roleWe're hiring a Staff Software Engineer to tackle some of the hardest technical problems at Onebrief — the kind that don't yet have a clear owner, a defined scope, or an obvious solution. We operate in a squad-based model: small, focused teams that form around outcomes and dissolve when the work is done. At the Staff level, you're not just effective within that model; you're one of the people who makes it work. You define technical direction before squads spin up, build the foundations that squads depend on, and bring coherence to decisions that would otherwise fragment across teams.
Our platform spans a modern full stack: a React/TypeScript frontend, Node.js backend services, cloud-native infrastructure, and authentication and identity systems. You'll operate across all of it, not just as a contributor, but as someone who shapes how we build.
About YouYou're energized by problems that are technically hard and organizationally complex. You don't wait for scope to be handed to you. You identify the highest-leverage work and pull it into focus. You've seen enough systems succeed and fail to have strong opinions, but you hold them lightly enough to change your mind when the evidence warrants it. You treat AI tooling not just as a productivity multiplier but as something worth thinking carefully about at the system level: how it changes the way teams build, review, and reason about code. You care deeply about the engineers around you and measure your own success partly by how much better they get.
What You'll DoDefine and drive cross-squad technical strategy, identifying systemic gaps, proposing architectural direction, and seeing complex initiatives through from framing to delivery.
Shape the conditions for squads to succeed: establish durable abstractions, shared patterns, and platform primitives that reduce friction across teams rather than within one.
Operate in the highest-ambiguity spaces: problems that aren't yet well-formed enough to assign to a squad, where your job is to bring clarity and make them tractable.
Drive architectural decisions that outlast any single squad rotation, balancing long-term system health with the pragmatic pace of a high-velocity org.
Establish and evolve engineering norms: how the team uses AI-assisted development, what good code review looks like, and how we reason about build vs. buy vs. adopt decisions.
Mentor and elevate engineers across squads, not through formal programs, but through the quality of your reviews, your RFCs, and how you show up in technical conversations.
Partner with product and engineering leadership to shape the roadmap from a technical perspective, surfacing constraints and opportunities that aren't visible without deep system knowledge.
12+ years of software engineering experience, with a track record of technical ownership that spans teams, not just projects
Demonstrated ability to set architectural direction at the org or platform level, not just within a team's scope
Fluency across the full stack, with the depth to go from frontend architecture to infrastructure trade-offs as the problem demands
Experience building in a squad or rotation-based model, or the clear instincts of someone who would thrive in one
Strong understanding of distributed systems, API design, data modeling, and cloud-native infrastructure at scale
Active and sophisticated use of AI coding tools, with a point of view on how they should be used well, not just used
Exceptional communication: the ability to write RFCs that get alignment, give feedback that lands, and make complex trade-offs legible to non-technical stakeholders
Comfort in ambiguity: you make progress without waiting for full clarity, and you bring others along rather than disappearing into a problem
Nice to Have Qualifications
Background in mission-critical or high-compliance domains (FedRAMP, SOC2, DoD)
Experience with authentication and identity infrastructure at scale (OIDC, SAML, federated identity)
Prior experience in a high-growth B2B SaaS environment scaling through significant inflection points
Familiarity with event-driven architectures and the trade-offs of async-first system design
Frontend: React, TypeScript, Vite, shared component libraries, client-side observability
Backend: Node.js, PostgreSQL, Redis, secure RESTful APIs, distributed services
Authentication & Authorization: Keycloak, OpenID Connect (OIDC), SAML 2.0, OAuth 2.0, ABAC, JWT, federated identity provider integrations
Infrastructure: Kubernetes, AWS, Terraform, CI/CD pipelines, container security and secrets management
Integrations: CSV/Excel/KML importers, PDF exports, DoD and enterprise data systems, secure API gateways, auditing pipelines

Onebrief Insights
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. Our funding has skyrocketed, most recently raising our Series C, led by top-tier venture investors who have deep expertise in defense tech.
Why Work With Us
Impactful Transformation At Onebrief, we believe optimizing the military staff is the most impactful thing - on a per-dollar basis - in defense tech right now. This has the potential to save the department of defense billions of dollars and save users countless hours. It’s a longstanding problem that we’re uniquely positioned to solve.
