Customer Success Engineer, Battle Road

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.

At Battle Road, we’re building the next generation of military modeling and simulation technology through AtomEngine, our modern, game-engine-based platform.

We are replacing decades-old legacy systems with a more accurate, flexible, and operationally relevant simulation environment. Our technology is already being used in major U.S. military training exercises and command environments.

We are seeking a Customer Success Engineer who wants their technical work to directly influence how military leaders train, plan, and make decisions.

This is not a traditional customer success role. This is mission-facing engineering.

As a Customer Success Engineer, you operate at the intersection of engineering and mission execution.

You will deploy into real-world military training environments, including Secret and air-gapped systems. You will configure, extend, and troubleshoot AtomEngine in high-visibility settings. You may be standing in front of senior officers, fielding questions, adapting simulations live, and ensuring the platform performs under pressure.

You are the last mile between cutting-edge simulation technology and the warfighter.

If you take pride in how you show up, remain composed in challenging environments, and enjoy earning trust and building advocates, this role will challenge and reward you.

You will operate at the tip of the spear between technology and mission execution.

• Deploy AtomEngine into live military training environments, including classified and air-gapped systems

• Configure and adapt entities, behaviors, and operational scenarios to reflect real-world requirements

• Troubleshoot technical issues in real time during high-visibility exercises, sometimes in front of large audiences

• Stand in front of officers, colonels, and generals to explain system behavior, answer questions, and build trust

• Teach technical concepts clearly to mixed technical and non-technical audiences, helping military stakeholders understand not just how the platform works, but why it works

• Lead or support training sessions, workshops, and instructional blocks as adoption scales

• Engage constructively with key stakeholders and respond to challenging questions with clarity and professionalism

• Translate real-world friction into actionable feedback for Product and Engineering

• Improve documentation and repeatability so deployments scale over time

• Travel up to 50%.

• You will operate in rooms where decisions matter

• You will help replace legacy systems that have been in place for decades

• You will represent Battle Road directly in front of officers, colonels, and generals

• You will see your work applied in real-world training environments

• 3+ years of professional experience in a software engineering, solutions engineering, or technical customer-facing role involving hands-on development

• Demonstrated experience writing and maintaining production-quality code, including extending existing frameworks, SDKs, or plugin systems

• Proficiency in at least one general-purpose programming language used for application or game-adjacent development (e.g., C#, Python, C++, GDScript, or similar)

• Strong systems thinking and understanding of modular, maintainable software design

• Comfort working with customers face-to-face to debug, iterate, and validate solutions in real-world environments

• Self-directed and effective in fast-moving, ambiguous environments

• Active Secret or Top Secret security clearance

• Prior military experience

• Willingness and ability to travel up to 50%

• Experience presenting or teaching technical concepts to large groups

• Experience in modeling, simulation, game engines, or defense-related systems
