Lead Process​/Chemical Engineer - Government Services

This position allows for a hybrid arrangement with a mix of work from home and in the office. This is an opportunity for an experienced chemical engineer to contribute to challenging and meaningful work in support of government clients. The role is ideal for a senior professional who brings strong technical judgment, experience in regulated environments, and the ability to lead engineering assignments while working closely with multidisciplinary teams.

• Perform chemical and process engineering evaluations, calculations, studies, and design support for government and DOE-related projects under an NQA-1 quality assurance program.
• Prepare and review technical reports, specifications, engineering documents, and other design deliverables.
• Support process systems, waste handling systems, material selection, corrosion evaluations, hazardous area classifications, system reliability analysis, risk management analyses and related plant or facility engineering efforts as project needs require.
• Coordinate with project managers, engineers, designers, and client representatives to define scope, resolve technical issues, and support successful project execution.
• Provide technical leadership, mentor less experienced staff, and contribute to high-quality project delivery.
• Support proposal development, scope definition, estimating, and schedule input as needed.

Must be a U.S. Citizen;
Dual citizenship with a country other than the U.S. does not qualify.

• Must be able to obtain US Government security clearance.
• BS in Chemical Engineering and/or MS in Chemical Engineering from an ABET-accredited program with a strong academic background.
• 10+ years of progressively responsible experience in Chemical/Process engineering.
• An understanding of the practical application of chemical/process engineering and technology, including applying systems, principles, techniques, and procedures to a project design, and mass and heat balances.
• Strong organizational skills with high attention to detail.
• Ability to quickly identify and prioritize issues, create solutions, and meet deadlines.
• Excellent written and verbal communication skills.
• Proficiency with MS Office applications.
• Able to occasionally travel as necessary to for client meetings, job site visits, start-up activities, off-site training, industry related conventions/seminars.

• Professional Engineering (PE) Licensure.
• Knowledge of any of the following programs: ASPEN or similar process modeling software, Micro Shield, MCNP, Crystal Ball, Block Sim, and Microsoft applications.
• Familiarity with major federal environmental regulatory programs such as the Clean Air Act, Clean Water Act, and Resource Conservation and Recovery Act.
• Multiple years of experience in a nuclear environment (DOE preferred, commercial or Navy), highly desirable.
• Experience with nuclear materials/wastes and their associated processes.

In this role, we expect people to be willing or able to lead others who use modern tools:

• You are expected to lead others in taking engineering problems from issue to solution by setting expectations for using data and modern tools such as automation and AI to improve workflows, reduce rework, and deliver cost-effective designs.
• Leaders in these roles often direct automation and process-improvement work, for example, how teams automate calculations, summarize technical documents, or generate design documentation and guiding when and how AI or agentic AI tools are used while ensuring results are checked.
• Overseeing engineers who program or script (e.g., Python, MATLAB, advanced Excel) to automate engineering tasks, with review of automated outputs, is valued but not required.
• We also value additional learning, such as a minor, certificate, or other experience in Computer Science, Artificial Intelligence, Software Engineering, or related fields that enables effective oversight of automation and agentic AI-enabled engineering workflows.
