Prepare and implement complex mechanical designs utilizing design criteria, calculations, schematics, sketches, construction documents, procedures, and specifications.

Utilize advanced technical engineering skills to develop detailed designs, drawings, calculations, bills of materials, presentations, and work planning documentation to support facility improvement projects including evaluating system capacities, planning sequencing of work, and ensuring construct-ability.

Determine functional mechanical requirements for new or modified specialized equipment and support systems and perform advanced mechanical engineering calculations for ventilation, fire protection, cryogenic or gas systems, chillers, or boilers as needed.

Provide engineering support during construction performed by outside contractors including reviewing submittals and shop drawings, responding to contractor questions, evaluating change order requests, or resolving field problems.

Lead complex internal mechanical system projects with responsibility for the development and compliance with technical criteria, schedules, and deliverables, and direct the work of mechanical designers and drafters preparing drawings prepared in AutoCAD for projects.

Participate in design reviews to obtain approvals of project scope and designs.

Provide technical input to others on complex design requirements and identify and evaluate potential system impacts for projects affecting facility systems while complying with LLNL procedures, work control system processes, and DOE requirements.
