Junior Software Engineer - Belay Technologies

Belay Technologies has been voted Baltimore Business Journal's (BBJ) Best Places to Work 2026!

Belay Technologies is seeking a Software Engineer to join our intel team. AIMASSIST brings AI into the operations organization, embedding engineers with the operators, analysts, and developers who carry out the CNO mission. Our engineers learn how those teams work, find the tasks that consume their time, and build AI agents and tools that let them move faster without giving up accuracy or control. We build on both frontier models and on-premises open-weight models, served through the customer's enterprise AI platform, and turn them into mission capabilities such as agents that triage incoming data, automate repetitive tradecraft, or research across disparate sources on an analyst's behalf. We are now introducing autonomous agents the mission can trust: agents that take real actions within guardrails, are measured against evaluations built with the people who use them, and log every step so a reviewer can follow what they did. As an Applied AI Engineer, you will join a forward-deployed team that works directly with a mission customer, building and improving the agents, Skills, and tools they use every day. You will work under the guidance of senior engineers, learn CNO tradecraft from the operators and analysts you support, and see the results of your work firsthand.

• Write test cases and evaluation examples that check whether AI capabilities return correct and reliable results
• Use AI coding agents in daily development, and understand and review generated code before committing it
• Collaborate with other engineers to test workflows, identify issues, and recommend fixes
• Create documentation and user guides that help mission users adopt new AI tools
