The Senior Mechanical Engineer supports centrifuge program activities involving mechanical components, assemblies, machines, plant expansion, thermal systems, vacuum systems, composite and machined parts. Responsibilities include design, structural and dynamic analysis, manufacturing equipment design, fabrication specifications, engineering packages, assembly procedures, process improvement, and cross-functional coordination. The role requires managing schedules and budgets while supporting engineering, manufacturing, testing, quality, and purchasing teams.

Designs, deploys, and operates secure, highly available OT/ICS networks for critical energy-sector infrastructure. Responsibilities include Purdue Model segmentation, industrial protocol support, firewalls, DMZs, network documentation, cybersecurity compliance, monitoring, automation, vulnerability management, audits, and incident response support. The role works onsite in sensitive facilities, collaborates with controls and cybersecurity teams, participates in on-call support, and must obtain and maintain a Q security clearance.

Analyzes real-time and historical process data to evaluate centrifuge and cascade performance, reliability, and operational conditions. Develops engineering calculations, models, spreadsheets, code, data-analysis tools, test plans, and technical evaluations. Supports nuclear material accountability, troubleshooting, operator training, procedure reviews, and Area Control Room decision-making using Excel, PI Vision, MATLAB, Python, and statistical methods.

Design and develop centrifuge components, assemblies, machines, and facility-related hardware from concept through released documentation. Create Creo 2D drawings and 3D models, perform engineering calculations, make material and tolerance decisions, lead design reviews, prepare fabrication and assembly documentation, support prototyping and testing, resolve production issues, and collaborate with manufacturing, quality, procurement, and operations.

Designs precision production gages and fixtures for machined components and assemblies, including go/no-go, functional, analytical, check, and CMM gaging. Creates 3D models and detailed drawings, updates existing designs, collaborates with Engineering, Quality, and Manufacturing, and manages project timelines and budgets. Requires expertise in GD&T, 3D CAD, manufacturing quality systems, and obtaining and maintaining a DOE Q-level security clearance.

Processes and reconciles biweekly payroll for exempt and non-exempt employees, ensuring accuracy, compliance, timely payments, and correct deductions. Maintains payroll and timekeeping data, handles special payments and employee inquiries, supports reporting and audits, and collaborates with HR and Finance on cost allocations and data integrity. The role also helps improve payroll processes and requires knowledge of payroll laws, tax principles, Excel, and HRIS or ERP systems.

Develops and manages integrated project baselines, schedules, cost estimates, risk considerations, and change controls. Monitors critical paths, cost and schedule performance, forecasts, budgets, and earned value metrics. Produces variance analyses, trend reports, and corrective-action recommendations while collaborating with project managers, control account managers, and cross-functional teams on complex, regulated technical projects.

Develops advanced instrumentation electronics, sensors, analog and digital circuits, data-acquisition systems, and LabVIEW tools for centrifuge manufacturing environments. Responsibilities include creating design specifications, managing electronics builds and testing, troubleshooting systems, preparing BOMs and procurement specifications, supporting production, leading project tasks, collaborating across disciplines, and mentoring engineers. The role requires electrical engineering expertise, industrial instrumentation experience, and the ability to obtain and maintain a Q security clearance.

Develop and maintain technical and administrative procedures compliant with NRC standards. Design and deliver performance-based training and instructional materials in partnership with subject-matter experts. Support records and commitment management, change evaluations, and procedure review to ensure consistency and operational safety.

Leads the redesign, rebuilding, commissioning, and modernization of centrifuge dynamic test stands. Directs high-speed rotor testing, vibration analysis, instrumentation, diagnostics, and performance verification while guiding cross-functional engineering teams. Plans multi-project testing, mentors engineers and technicians, coordinates suppliers, and ensures compliance with DOE/NQA-1 quality, safety, and security requirements. Supports enrichment technology development in a DOE-regulated environment.
