Position Summary
We are seeking a versatile Software Engineer with 5+ years of experience to support our Applied Computational Engineering group, with cross-cutting support to our Ocean Systems and Sustainment groups. This is a role for a self-directed engineer who thrives juggling multiple projects in a fast-paced, quick-turnaround environment.
A primary focus of this role is transforming research-level code into production-ready software: secure, optimized for runtime performance, user-friendly, clean, and modular, and integrated with other software systems (for example, via well-defined APIs). The codebase is primarily C++, so strong C++ proficiency is essential, complemented by competency across additional languages including Python, MATLAB, and Java. Strong skills in coding, debugging, design, problem-solving, technical writing, and presentations are required, along with the ability to manage multiple projects and work both independently and collaboratively. Another core component of this role is the ability to develop and apply novel artificial intelligence and machine learning (AI/ML) methods and algorithms to solve challenging technical problems across our customer base.
This position is scoped to accommodate a range of experience. Candidates with 5+ years will be considered at the Project Software Engineer level, while candidates bringing deeper experience (up to ~15 years) may be considered at a more senior level commensurate with their background.

• Refactor, optimize, and harden existing C++ code for performance, robustness, and maintainability.
• Apply secure coding practices throughout the development lifecycle to deliver cybersecure software.
• Apply runtime optimization techniques such as parallelization or GPU acceleration to improve performance.
• Execute systems engineering tasking, including requirements definition, architecture, interface design, and integration planning.

AI/ML and Algorithm Development

• Develop, apply, and implement novel AI/ML methods and algorithms to address customer and program needs.
• Translate AI/ML research and prototypes into robust, deployable, production-ready software.
• Evaluate, benchmark, and optimize AI/ML models for accuracy, performance, and runtime efficiency.

Integration and User Experience

• Design and integrate software interfaces with other software systems (e.g., via APIs).
• Support UI/UX design and GUI development to deliver intuitive, user-friendly software.
• Establish and maintain documentation, version control, testing, and build/integration workflows.

Collaboration and Customer Support

• Coordinate and balance a diverse portfolio of tasks to support engineers across the company.
• Support customer meetings, demonstrations, and other externally facing activities.

• Experienced developer with strong coding, debugging, design, and problem-solving skills.
• Strong proficiency in C++, with working competency across additional languages such as Python, MATLAB, and Java.
• Experience developing and applying AI/ML methods and algorithms.
• Demonstrated experience taking software from prototype/research code to robust, production-ready quality.
• Experience with secure coding practices and software cybersecurity fundamentals.
• Familiarity with secure development frameworks or DoD cyber compliance practices.
• Experience using collaborative source code management (Git, Subversion), Agile Development, and DevSecOps.
• Strong organizational skills with the ability to multi-task, readily adapt to change, and respond to quick-turnaround requests.
• Self-starter who is highly organized, professional, and able to work both independently and as part of a team.
• Strong skills in technical writing, documentation, and presentations.

Desired Qualifications

• Signal processing experience.
• UI/UX design and GUI development experience.
• Experience with trajectory simulation.
• Experience designing and integrating APIs and software interfaces across heterogeneous systems.
• Familiarity with modeling, simulation, and/or numerical/computational methods.
• Experience with CI/CD pipelines, automated testing, and static analysis tools.

Education/Experience

• BS in Computer Science, Software Engineering, or a related discipline. Advanced degree preferred.
• 5+ years of relevant software development experience (additional experience considered for senior-level placement).
