Everforth ECS is seeking a Senior Computational Scientist to work in our Springfield, VA customer site and Fairfax, VA corporate site.
Everforth ECS is seeking a highly skilled and visionary Senior Computational Scientist lead the development, scaling, and deployment of advanced mathematical, statistical, and computational models. In this role, you will bridge the gap between complex theoretical science, Artificial Intelligence/Machine Learning (AI/ML), and high-performance computing (HPC) engineering. You will design robust algorithms, optimize high-performance codes, and lead cross-functional research initiatives that directly support our critical national security and defense mission datasets.
As a Senior Computational Scientist, you will leverage statistical and AI/ML algorithms to deliver advanced analytics, including predictive analysis and modeling, pattern-of-life analysis, and remote sensing change detection. You will manage the entire computational algorithm development lifecycle from design and training to deployment and maintenance while ensuring performance, observability, and security. This role contributes to building scalable infrastructure, integration layers, real‑time dashboards, and automated pipelines that enable secure, compliant, and efficient AI operations aligned with mission and business goals.
Key responsibilities include:
- Design, implement, and validate complex computational models and simulations
- Apply advanced machine learning, deep learning, and statistical physics methodologies to large-scale, structured and unstructured datasets
- Optimize, parallelize, and scale scientific software across hybrid GPU/CPU cluster architectures
- Lead end-to-end data science initiatives, encompassing the design, training, and production deployment of AI/ML algorithms
- Partner with domain experts (aerospace, cybersecurity, intelligence) to translate mission needs into computational requirements
- Write white papers, proposals, and technical documentation. When possible, publish in peer-reviewed journals
- Mentor junior computational scientists, engineers, and data analysts on scientific software best practices
Salary Range: $180,000-250,000
