Original job description

Company Summary

Triton Systems, Inc combines 30+ years of experience with exciting growth and innovation opportunities within the product development and R&D space. We support Government and commercial markets by delivering advanced solutions across applications in defense, security, aerospace, energy, environmental sustainability, and human health. Where we see a larger opportunity, we create new companies to scale these solutions into businesses. Our teams thrive in a collaborative, fast-paced environment where we tackle complex challenges, meet our customers' toughest requirements, and deliver high-impact results on time, on budget and have fun while doing it..

Position Summary

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 Triton's "Senior Scientist" or "Senior Engineer" level .Exceptional candidates with 5+ years may be considered at a level just below Senior.

Technical Leadership and Project Execution

Provide technical leadership and direction on computational simulation projects, from approach through delivery.
Partner with the Program Manager to plan, schedule, and execute objectives, tracking milestones, risks, and resources.
Help maintain project schedules, ensuring deliverables are high quality and on time.
Delegate and oversee tasks for small teams of engineers and academic collaborators, providing clear direction and technical review.
Interface directly with government customers, supporting and leading meetings, technical reviews, and demonstrations.
Coordinate with academic, subcontractor, and industry partners, managing tasking and integrating contributions.
Prepare and own technical reports, presentations and contract deliverables.
Contribute to and lead proposal efforts and identify transition and commercialization opportunities.
Ensure compliance with export control (ITAR/EAR) and information security requirements.

Numerical Methods and Physics Modeling

Develop, analyze, and optimize numerical algorithms to accelerate trajectory simulations, including high-order integration methods for systems of ordinary differential equations.
Perform convergence, stability, and error analysis to achieve target accuracy with fewer time steps and lower computational cost.
Model the physics of atmospheric and orbital flight, including equations of motion, gravity, aerodynamics, and coordinate frame transformations.
Verify and validate algorithm accuracy and performance against established simulation tools and benchmark scenarios.
Apply AI/ML methods where they offer advantages for acceleration, surrogate modeling, or analysis.

Scientific Software Development

Implement numerical methods in robust, efficient, and maintainable C++ code.
Mature research code into production-ready software that is secure, optimized, clean, and modular.
Apply performance techniques such as parallelization, vectorization, or GPU acceleration.
Design software for integration within distributed simulation environments.
Define requirements, architecture, and interfaces, and plan integration with other systems.
Maintain documentation, version control, testing, and build workflows, applying secure coding practices throughout.

Technical Communication and Recognition

Communicate complex mathematical and technical concepts clearly to customers, partners, and team members.
Serve as a subject matter expert (SME) in computational simulation to support other Triton technical staff, customers and partners.

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.
