Lead Mechanical Engineer -- Energy & Industrial Group

Sargent & Lundy•Clayton, MO

1d•Hybrid

About The Position

Your responsibilities will include, but are not limited to: You will be responsible for leading the Mechanical Engineering design efforts for a team of junior and senior engineers and designers. You will work on challenging assignments that include investigating, trouble-shooting, and solving a wide variety of mechanical engineering issues. Act as the Mechanical team lead in the coordination of detailed design phases for all aspects of mechanical engineering work. Develop integrated systems designs and perform supporting calculations for the planned work. Prepare technical specifications for mechanical engineering equipment. Prepare engineering studies. Perform independent reviews of work performed by others including calculations and drawing preparation. Coordinate and provide guidance to other engineers, project managers, client personnel, and suppliers to ensure a complete and timely design. Perform reviews of existing facilities to propose upgrades and replacements, and present findings and recommendations to clients and peers. Develop your career via peer-learning through sharing of knowledge with other experienced engineers by way of S&L’s systems of process and associated “Communities of Practice.” Provide guidance as a mentor in the development of less experienced engineers. This position is based on a hybrid work schedule based in our Clayton, Missouri office, located within the St. Louis metropolitan area and will require in-office work 3 days per week. The Energy & Industrial Group (EIG) specializes in delivering advanced engineering solutions across various sectors, including power generation, environmental compliance, oil & gas, and industrial projects, from new plant design to plant betterment and upgrade services for operating facilities. We have designed nearly 900 conventional power plants, yielding over 100,000 megawatts (MW) of generation capacity. Our expertise includes numerous recent and ongoing combined cycle projects that leverage the latest advanced machinery, including combustion turbines, steam turbines, and heat recovery steam generators from all leading suppliers. EIG is recognized for its commitment to decarbonization through innovative technologies in renewable energy, carbon capture, and hydrogen power. We excel in detailed engineering services for photovoltaic (PV) solar projects and energy storage integration, and lead the industry in carbon capture technologies, managing projects from conceptual studies, pilot demonstrations and through commercial scale implementation for utilities and industrial plants.

Requirements

BS in Mechanical Engineering from an ABET Engineering Accreditation Commission-approved program is required
7+ years of experience in the design of mechanical engineering systems for non-commercial, heavy industrial plants (power, oil & gas, or chemical), with a focus on integrated, detailed system design for new plants, modifications, or replacements; Experience must include the selection of equipment, piping materials, control philosophy, and the preparation of performance sizing calculations and specifications.
Three or more years experience in leading an engineering design team through all phases of a project design.
Technically knowledgeable of available equipment and proven pre-engineered systems to execute systems design.
Able to create design schematics, such as flow diagrams and P&IDs, using computer design software.
Experience with serving as firm/client liaison in a support or lead engineering role.
Experience in reviewing design drawings created by others.

Nice To Haves

MS in Mechanical Engineering preferred.
Construction and start-up experience a plus.
PE license.
Commissioning experience a plus.
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.
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.
