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.
About the roleWe’re hiring a Staff Software Engineer to design, build, and operate the authentication and identity systems that power our platform. This is a hands-on engineering role with a focus on reliability, scalability, and secure user experience. Our authentication stack is built on modern technologies including Keycloak, OIDC/SAML/LDAP integrations, and cloud-native infrastructure. We value strong problem-solving skills, sound engineering judgment, and a deep understanding of distributed systems and security principles.
You’ll work on high-impact systems including (but not limited to) identity provider integrations, access control frameworks, token management, and policy enforcement infrastructure. Expect to tackle challenges in federated identity, Attribute-Based Access Control (ABAC), multi-tenant authorization, session management, and fault-tolerant authentication flows. You’ll play a key role in shaping our authentication architecture and defining the long-term strategy for identity and access management across the platform.
If you enjoy thinking deeply about security trade-offs, scaling authentication systems, and building reliable identity foundations that balance usability with robust access control, you’ll thrive here.
What you'll doDesign, build, and maintain authentication and identity services that power mission-critical platform access and authorization.
Integrate and extend Keycloak to support complex identity provider (IdP) integrations, single sign-on (SSO), and federated authentication.
Implement and evolve Attribute-Based Access Control (ABAC) frameworks to enable fine-grained, policy-driven authorization across systems.
Work across the stack — from APIs and access tokens to infrastructure automation, deployment, and observability of authentication workflows.
Diagnose and resolve reliability, latency, and scalability issues in production authentication and authorization flows.
Collaborate on architecture and long-term strategy for secure, resilient, and high-availability identity systems.
Implement and refine monitoring, auditing, and alerting for authentication and access events to ensure security visibility and compliance.
Balance security, user experience, and delivery velocity, ensuring pragmatic decisions that maintain both product agility and engineering quality.

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.
