• Develop and maintain API specifications, interface control documentation, data mappings, configuration, test evidence, operational procedures, and troubleshooting guidance.
• Collaborate with data, workflow, dashboard, platform, security, testing, and mission teams to deliver end-to-end capabilities.
• Troubleshoot integration failures, analyze performance and reliability, resolve defects, and improve observability and supportability. Minimum Qualifications and Experience
• Active DoD Top Secret/SCI clearance.
• Current DoD 8140/8570-compliant baseline certification appropriate to the assigned position, such as Security+, CySA+, GSEC, SSCP, or another approved credential.
• U.S. citizenship.
• Three or more years of relevant experience in systems integration, API development, middleware, backend development, data integration, ETL, or a related discipline; equivalent education, training, certifications, and experience will be considered.
• Hands-on experience with APIs, web services, databases, data formats, authentication, or integration platforms.
• Working knowledge of REST, JSON, XML, data mapping, error handling, security, testing, observability, and production support concepts.
