Evaluate emerging technologies, frameworks, and methodologies to recommend solutions that improve system capabilities and efficiency. Ensure system designs comply with Department of Defense cybersecurity standards such as Risk Management Framework (RMF), STIG compliance, and FISMA/NIST guidelines. Implement robust security measures to protect data integrity and safeguard classified information from unauthorized access or breaches. Collaborate with cybersecurity teams to embed secure coding practices and hardening strategies into all software deliverables. Collaborate with engineers, testers, and stakeholders to integrate software solutions with DoD systems and platforms effectively. Provide post-deployment support, resolving technical issues and optimizing software functionality. Develop detailed design documentation, user manuals, and technical diagrams for stakeholders. Provide expert-level input for program reports, lifecycle cost estimates, and risk analyses for leadership review. Serve as the Subject Matter Expert (SME) for designing and integrating software systems in secure environments. Provide technical guidance and mentoring to development teams across the software lifecycle, including requirements analysis, design, coding, testing, deployment, and maintenance. Support root-cause analysis and resolution of critical technical issues related to system performance, scalability, or cybersecurity vulnerabilities. Deliver expert recommendations on the selection of programming languages, development tools, and software patterns. Expertise in modern programming languages such as Python, Java, C++, or similar. Deep understanding of software development methodologies, including Agile, DevSecOps, and waterfall models. Knowledge of Department of Defense systems and secure development requirements (e.g., STIG, RMF, MIL-STD compliance). Proficiency in cloud computing platforms (e.g., AWS, Azure, or DoD Cloud solutions) and containerization technologies (e.g., Docker, Kubernetes). Strong analytical and problem-solving skills to address complex, mission-critical challenges. Exceptional communication skills to coordinate with stakeholders and convey technical concepts effectively.
