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 Principal AI/ML Engineer to lead the design and implementation of enterprise-grade AI systems that power mission-critical operations. In this role, you will architect scalable AI infrastructure, deliver practical AI solutions that solve real operational challenges, and drive technical strategy for our AI-powered products.
You'll apply cutting edge AI to transform complex military requirements for planning critical operations into robust production-ready systems. You will have the opportunity to redefine distributed human-AI collaboration at scale with the use of multi modal foundation models, multi-agent orchestration and knowledge graph driven reasoning.
Expect to lead cross-functional technical initiatives, mentor engineers, and establish technical standards that enable rapid innovation while ensuring reliability. The solutions you design must be robust, scalable, and able to support thousands of users in regulated, offline-capable environments.
What You'll DoPartner with product, domain experts, and leadership to translate operational needs into technical roadmaps.
Define system-level standards for model development, evaluation, and deployment, while mentoring senior and staff level engineers through collaboration.
Drive long term AI/ML architecture at Onebrief.
Agent Orchestration: Design systems that coordinate multiple AI agents, tools, and workflows to accomplish complex operational tasks.
Design and implement enterprise-scale AI infrastructure supporting retrieval, generation, and multi-modal reasoning.
Build and scale graph-based systems for structured representation, reasoning, and integration with generative models.
Apply LLM practices like RAG & prompt engineering to deliver grounded & reliable outputs for mission planning
Establish evaluation frameworks and SLO's for RAG quality, agent reliability, and system performance in production
Collaborate with infrastructure teams to ensure high quality data pipelines to power AI applications
M.S. in Computer Science, Engineering, or equivalent practical experience
10+ years in large scale distributed systems, ideally supporting more than 100k concurrent users
Proven experience designing and deploying AI systems at scale in distributed, production environments
Strong background in integrating LLMs with retrieval systems for real-world use cases
Understanding of data governance, model safety evaluations, red-teaming, and secure ML practices for regulated domains
Experience with building systems with information retrieval (relevance & ranking), natural language processing techniques like Named Entity Recognition (NER)
Preferred Qualifications
Background in defense, national security, or other mission-critical domains
Experience with orchestrating systems that combine text, structured data, and domain-specific signals

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.
