Junior Software Engineer Jobs in Ohio (NOW HIRING)

Mission Impact At MTSI, you'll build and enhance enterprise catalog and metadata services that power intelligence discovery across the Air Force and Intelligence Community. Your work will modernize how analysts access, curate, search, and share mission data, enabling rapid, secure, cloudnative information flow across domains and security enclaves, directly strengthening decision advantage in contested environments. What You'll Do (DaytoDay) Support the development and enhancement of Catalog Collection services such as the Catalog Service, Object Store, Metadata/Tagging services, Source Citation Manager, and Enterprise Search.

Assist with maintenance, sustainment, bug fixes, and minor enhancements to existing catalog capabilities running within the NASIC Unified Cloud (NUC) and DAF CLOUDworks environments. Help implement and test cloudnative components using containerization and CI/CD processes required for deployment across multiple security enclaves. Contribute to developing and updating API documentation, OpenAPI specifications, user guides, and onboarding material for internal and external catalog service users.

Participate in Agile Scrum ceremonies, contribute to team discussions, review work items, and collaborate with Government SMEs and other developers. Support integration testing and verification of catalog services as they interact with ICAM Services, Foundational Services, EPAS, and mission applications. Assist with documenting design updates, architecture changes, endpoints, dependencies, and versioning for catalog services as required by CDRLs.

You'll Be a Great Fit If You... Are excited to learn how enterprise cataloging, metadata management, and search systems support critical intelligence workflows. Enjoy working with APIs, data models, and cloudnative software development

Thrive in collaborative, Agile environments and want mentorship from senior engineers and architects. Are curious about eventdriven architectures, metadata tagging, and how catalog services power enterprisewide data discovery. Are motivated to grow into a role that includes designing scalable catalog services and contributing to R&D efforts over time.

Responsibilities (Expanded) Assist with implementing catalog features such as metadata tagging, lookup and resolution logic, labeling workflows, object registration, and citation tracking. Help maintain and integrate Catalog Collection capabilities into cloud environments (NUC and CLOUDworks), adapting to evolving infrastructure and ensuring stable deployments. Support the development of onboarding and enablement materials for new catalog service users, including API references, training content, and example workflows.

Contribute to testing, refactoring, and validating catalog services to ensure reliability, interoperability, and compliance with NASIC's approved technology stack.
