Lead Mechanical Engineer

FST Technical Services is hiring a Lead Mechanical Engineer to support a semiconductor industry project in the Santa Clara, California area. This is a Senior Engineering role responsible for technical direction, team leadership, client management, project planning, budget and forecasting oversight, and successful delivery of mechanical engineering and commissioning activities.

The successful candidate will have significant experience working within the semiconductor, advanced manufacturing, high-technology, or similarly complex industrial environment, with a strong understanding of mechanical systems, project execution, commissioning, construction, and client requirements.

Position Overview

The Lead Mechanical Engineer will provide overall leadership for mechanical engineering, commissioning, and field execution activities associated with a major semiconductor industry project.

This role combines technical leadership, team management, client leadership, project controls, budget management, forecasting, and project delivery. The successful candidate will work closely with the client, engineering and design teams, contractors, vendors, project management, and FST leadership to ensure project objectives are achieved.

The ideal candidate will be comfortable operating in a fast-paced, technically complex environment and will have demonstrated experience leading multidisciplinary teams and managing projects from planning and design through construction, commissioning, turnover, and closeout.

What You’ll Do

• Lead and provide technical direction to mechanical engineering, commissioning, and field teams.

• Manage team performance, priorities, staffing, development, and resource requirements.

• Serve as a senior technical and operational point of contact for the client and key project stakeholders.

• Lead client meetings, project reviews, technical discussions, and progress updates.

• Build strong client relationships and identify opportunities for future business.

• Develop and manage project budgets, forecasts, staffing plans, and resource projections.

• Monitor project financial performance, identify risks and scope changes, and support commercial discussions.

• Provide leadership through project planning, design, construction, commissioning, startup, turnover, and closeout.

• Coordinate mechanical activities with contractors, vendors, engineering consultants, and other disciplines.

• Review mechanical designs, specifications, submittals, schedules, testing requirements, and commissioning documentation.

• Monitor project progress, identify schedule risks, and lead technical issue resolution and field troubleshooting.

• Ensure work meets client requirements, applicable codes, quality standards, and FST procedures.

• Oversee commissioning, startup, testing, documentation, deficiencies, and project turnover.

• Provide clear project status, financial, and operational reporting to FST leadership and the client.

The Lead Engineer will ensure project documentation is accurate, complete, timely, and aligned with client requirements. The role will also be responsible for identifying documentation gaps, unresolved technical issues, and project risks that could impact schedule, cost, quality, or client acceptance.
