Sr. Computational Scientist/Engr.

We are seeking a Senior Computational Scientist / Engineer to provide technical leadership on research and development efforts within our Applied Computational Engineering group. This role is for a self-directed technical leader who combines deep expertise in applied mathematics and physics with strong C++ software skills and thrives in a fast-paced environment. You will advance methods for efficiently running high-fidelity simulations of atmospheric and orbital flight, with a focus on achieving greater accuracy with fewer computational resources. You will guide a small technical team, coordinate with academic and industry collaborators, and work closely with a program manager to plan and execute project objectives that directly contribute to national security supporting the Department of Defense. You will also turn prototype numerical algorithms into production-ready simulation software that is secure, high-performance, modular, and integrated with other systems through well-defined APIs. Candidates with 7+ years of experience will be considered at Tritons Senior Scientist or Senior Engineer level .Exceptional candidates with 5+ years may be considered at a level just below Senior. Required Qualifications U.S. Citizen with an active Secret clearance or the ability to obtain and maintain one. Deep understanding of applied mathematics, including ordinary differential equations, numerical analysis, and numerical integration methods. Strong physics foundation, including classical mechanics and dynamics relevant to flight and orbital trajectories. Strong proficiency in C++ for scientific or high-performance computing, with working competency in Python, MATLAB, and Java. Demonstrated technical leadership, such as serving as a technical lead or task lead on funded R&D projects. Experience with client interfacing and customer management, including leading technical meetings and presentations. Experience coordinating partners, subcontractors, or academic collaborators and delegating work to small technical teams. Strong organizational skills with a proven record of delivering contract deliverables on time. Excellent technical writing skills, including reports, proposals, and documentation. Experience with source control (Git, Subversion), Agile development, and secure coding practices. Desired Qualifications Experience with trajectory simulation, flight dynamics, 6-DOF modeling, or orbital mechanics. Experience with power series or Taylor series methods for ODEs. Experience with federated or distributed simulation frameworks. Experience with defense modeling and simulation. Experience with parallel computing, GPU programming (e.g., CUDA), or HPC environments. Record of successful SBIR/STTR or other government R&D proposals. Publications, presentations, or patents in a relevant technical area. Experience applying AI/ML methods to scientific computing problems. Familiarity with DoD cyber compliance, CI/CD pipelines, and automated testing. Education/Experience MS or Ph D. in Applied Mathematics, Physics, Aerospace Engineering, Computational Science, or a related field strongly preferred. BS with equivalent experience considered. 5-7 years of relevant experience in computational modeling, simulation, or scientific software, including technical leadership.
