DoD Software Engineer – Data Interop & API Adapters (Crane, IN)

Science Applications International Corp.; Bedford (IN); On-site; USD 90,000 - 120,000; Full time

Job summary

Science Applications International Corp. seeks a Mid-Level Software Developer to support a government-owned, data-centric interoperability capability at NSWC Crane.

You will design adapters, develop SDKs and APIs, and participate in the full lifecycle in an Agile/DevSecOps environment, using Linux, C/C++, Java, or Python. Ideal candidates have hands-on Linux development experience and prior DoD/DoN program background, with a passion for delivering mission-critical capabilities to warfighters.

Qualifications

• Bachelor's degree in computer science, Software Engineering, Electrical Engineering, or a related technical discipline.
• 3+ years of professional software development experience, including work on interface, integration, API, or data-translation software.
• Prior experience working on-site at a Naval or DoD installation.
• Interim secret clearance with the ability to obtain a secret clearance. SAIC will sponsor the clearance process.
• US Citizen.
• Must be local to or willing to relocate to the Crane, Indiana area. This position is on-site at NSWC Crane.

Responsibilities

• Design, code, and test adapters that translate proprietary protocols from legacy and emerging sensors, effectors, cyber capabilities, and C2 systems into a common, vendor-neutral data format. Help expand and maintain the common data schema.
• Develop, document, and update developer-friendly SDKs and APIs that enable rapid, vendor-agnostic integration by government and third-party developers.
• Participate in the full software development lifecycle in an Agile/DevSecOps environment, including requirements analysis, design, coding, unit and integration testing, and documentation. Contribute to the Software Lifecycle Development Plan.
• Develop and maintain software in Linux-based environments using C, C++, Java, and/or Python. Check all code into government-controlled repositories (e.g., Bitbucket) and follow project coding standards.
• Support software builds, configuration management, and version control using Git, Jenkins, or similar CI/CD pipelines. Integrate automated unit testing, container scanning, and security vulnerability linting.
• Build, containerize (Docker or government-approved equivalents), and deploy cloud-ready applications, microservices, and adapters. Support Kubernetes orchestration, secure container registries, and the security controls for Authority to Operate (ATO) packages.
• Develop tools and dashboards that collect and report on performance and integration statistics. Analyze data flows to optimize message passing, reduce latency, and support backwards compatibility and interoperability.
• Support software verification in Live/Virtual/Constructive (LVC) and hardware-in-the-loop (HWIL) environments. Troubleshoot defects found in lab, test, and field events, and turn anomalies into backlog items and design changes.
• Follow change control and environment promotion practices (Dev/Test/Prod) and help prevent "code drift" while supporting controlled third-party adapter contributions.
• Produce and maintain technical documentation, including interface documentation, test plans and procedures, and technical data package inputs. Support developer-facing manuals and training materials.
• Collaborate with systems engineers, hardware engineers, and government stakeholders on software interfaces. Participate in software design reviews, test readiness reviews, post-test reviews, and technical meetings.
• Provide on-site technical support during integration events, demonstrations, and exercises.
