About The Position

At Battle Road by Onebrief, 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 develop features for, extend, and configure AtomEngine iteratively onsite with customers. You may be standing in front of senior officers, fielding questions, adapting simulations live, and ensuring customers achieve their goals on the platform. 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. This role will require travel to visit customers onsite at least 50% of the time. Travel can vary from a few days to a few weeks at a time.

Requirements

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
Willingness and ability to travel at least 50% of the time

Nice To Haves

Experience presenting or teaching technical concepts to large groups
Experience in modeling, simulation, game engines, or defense-related systems

Responsibilities

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.
Work directly onsite with various customers, embedded with customers to learn their needs and iterate alongside them.
Write code to develop capability at the edge, prototyping and implementing new AtomEngine features that help customers achieve their goals via both the Mod Kit and source control branches.
Partner with the core product & engineering teams to learn the code base and drive changes back to the mainline.
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.
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.
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 at least 50% of the time to client sites.
