Dedicated People. ### About Onebrief Onebrief builds collaboration and AI-powered workflow software for military planning and operational coordination. Military planning is complex by nature, requiring teams to coordinate information, people, and decisions across systems and locations. Onebrief brings planning, collaboration, simulation, and AI into one connected environment, helping teams test strategies, adapt to changing conditions, and make decisions with greater clarity when the stakes are real. We are a distributed team of builders from military, operational, and technology backgrounds who care deeply about improving how important work gets done. Some team members work remotely, while others work directly alongside customers in operational environments around the world. Founded in 2019, Onebrief is backed by leading investors including General Catalyst, Battery Ventures, Insight Partners, Sapphire Ventures, and Human Capital. Valued at more than $2 billion, we continue to invest in product innovation, AI capabilities, and team growth. ### Why This Role Exists As a Customer Success Engineer at Onebrief, you operate at the intersection of engineering and mission execution. You'll deploy AtomEngine into real-world military training environments, including Secret and air-gapped systems, where you'll configure, extend, troubleshoot, and improve the platform while working directly with customers. You may be supporting live exercises, adapting simulations, or ensuring the software performs under pressure. You are the last mile between AtomEngine's simulation technology and the warfighter. ### What You'll Do - Deploy, configure, and support AtomEngine in live military training environments, including classified and air-gapped systems, by extending entities, features, behaviors, sensors, and operational scenarios through AtomEngine tooling and scripting to reflect real-world requirements. - Embed onsite with customers at Fort Belvoir to understand operational needs, iterate alongside users, ensure successful deployments, and translate real-world friction into actionable Product and Engineering feedback by providing military context and operational priorities that enable engineering teams to prioritize effectively. - Integrate AtomEngine with partner systems by configuring and troubleshooting APIs, networking, infrastructure dependencies, and system connectivity, while resolving technical issues in real time during high-visibility exercises—including in front of large audiences—and implementing technical fixes to ensure the software functions optimally for upcoming customer exercises. - When not supporting active exercises, proactively identify and implement improvements from the enhancement backlog, contributing directly to the engineering backlog alongside the Software Engineering team using technologies such as Godot, C++, C#, and Python. - Communicate technical concepts clearly to military stakeholders, partners, and internal teams by explaining complex capabilities, engaging constructively with key stakeholders, and responding to challenging questions with clarity and professionalism. - Improve documentation, deployment processes, and operational repeatability to enable scalable deployments and long-term customer success. - Travel occasionally to support customer engagements and operational exercises. ### Minimum Qualifications - 3+ years of experience in software engineering, solutions engineering, technical consulting, or another customer-facing engineering role involving hands-on development. - Demonstrated experience writing and maintaining production-quality software, with proficiency in one or more programming languages such as C++, C#, Python, GDScript, or similar. - Experience troubleshooting software systems, integrations, networking, or distributed applications, with strong communication skills and the ability to explain technical concepts to both technical and non-technical audiences. - Comfortable working independently in fast-paced, ambiguous environments while collaborating closely with customers and engineering teams. - Prior military experience and Active Secret security clearance. - Willingness and ability to work onsite at Fort Belvoir daily and travel to other sites approximately 20% of the time. ### Preferred Qualifications - Experience presenting or teaching technical concepts to large groups. - Experience in modeling, simulation, game engines, or defense-related systems. ### Indicators of Success This role will evolve as priorities change, but the outcomes below reflect what success typically looks like in the first six months. A successful Customer Success Engineer will: - Independently deploy and support AtomEngine in assigned customer environments, maintaining reliable performance during live exercises. - Translate customer needs and field observations into actionable product feedback and technical improvements. - Build trusted customer relationships through clear communication and effective technical support. ** Notice to Third Party Recruitment Agencies** Please note that Onebrief does not accept unsolicited resumes from recruiters or employment agencies.
