• Oversee and participate in the installation of industrial and electrical components as part of mechanical systems.
• Ensure quality workmanship by participating in and passing weld tests as required, including dual shield and TIG weld evaluations.
• Plan daily work, assign tasks to crew members, and monitor progress to meet project schedules and production goals.
• Maintain a safe work area and enforce adherence to safety procedures and construction site regulations.
• Travel between shop and field locations in company vehicles and support field installations across multiple sites.
• Collaborate with other team members to address issues in the field and in the shop, ensuring equipment and structures are installed correctly.
• Support new builds and installations by adapting to changing project needs and assisting with backlog work as required.

Essential Skills

• Proven experience leading a team in mechanical installation or industrial construction environments.
• Strong mechanical aptitude with hands-on experience using hand tools and power tools for assembly and installation.

• Willingness and ability to travel regularly between shop and multiple field sites using company vehicles.
• Capability to work 5–6 days per week on 8–10 hour shifts in a construction environment.
• Commitment to safety practices on active construction sites.

Additional Skills & Qualifications

• Experience working on large industrial or agricultural construction projects.
• Familiarity with electrical aspects of industrial installations.
• Prior experience in a foreman or lead role supervising crews of similar size.
• Comfort working with a small, tight-knit team and contributing to a growing crew.
• Ability to pass a weld test, including dual shield and TIG welds.
• Experience working across multiple job sites and managing changing priorities.

Why Work Here?

You will join a small, close-knit crew where teamwork and mutual support are central to how work gets done. The company provides transportation in company vehicles to job sites, and drive time is paid at regular rates without counting against overtime calculations. With a strong backlog of new builds and installations, you can expect steady, long-term work and opportunities to grow as the team expands. The environment values hands-on craftsmanship, collaboration, and the chance to take pride in building complex industrial systems from the ground up.

Work Environment

The role is based in a construction environment focused on new industrial builds, including a pistachio facility and similar agricultural and industrial projects. You will split time between a fabrication shop and active field sites, working with a team currently around 15 people and expected to grow to approximately 20 by the end of the year. Work involves 5–6 days per week with 8–10 hour shifts, using hand tools, power tools, welding equipment (dual shield, TIG, MIG), and other industrial fabrication tools. You will travel in company vehicles to various locations, with work sites ranging across multiple areas. The setting is a typical industrial construction environment that requires appropriate work attire, adherence to safety standards, and comfort working outdoors and around heavy equipment.
