We are seeking a Facilities Engineer to support both facilities infrastructure projects and ongoing facilities operations in a lean, fast‑paced manufacturing environment. This role blends engineering, construction project execution, and facilities management, with a strong emphasis on electrical systems, HVAC, and building utilities.

You will be a key partner to the Director of Facilities in delivering infrastructure projects, supporting daily operations, improving system reliability, long‑range planning, and mitigating risks. The role is hands‑on and cross‑functional, spanning project execution, preventative maintenance, contractor coordination, and continuous improvement across active manufacturing facilities. This position requires comfort operating in ambiguous environments, taking ownership from problem identification through resolution, and making sound engineering judgments with limited direction.

• Develop and manage project schedules and budgets for small to mid‑sized facilities projects.
• Develop project scopes, support cost estimates, and track scope, schedule, and budget impacts.
• Coordinate design and execution of projects involving electrical distribution, HVAC systems, and building utilities (compressed air, process water, domestic water, natural gas, drainage, etc.).
• Support permitting, plan review, and AHJ coordination in partnership with Facilities and EHS.
• Provide construction oversight, including contractor coordination, site walks, issue resolution, and punchlist closeout.
• Identify infrastructure capacity constraints, single points of failures, and system risks.
• Contribute technical input to capital planning and prioritization for a multi‑year facilities infrastructure roadmap.

• Support development and review of engineering design packages for facility systems.
• Perform field verification and site walks to validate existing conditions and inform design decisions.
• Review and manage contractor submittals and coordinate responses to RFIs.
• Coordinate utility routing and service connections to support manufacturing equipment and work centers.
• Maintain and update redlines and as‑built documentation to reflect actual field installation.

• Support day‑to‑day facilities operations, troubleshooting issues related to electrical systems, HVAC, and building utilities.
• Process gas commodities management (helium, hydrogen, nitrogen, argon, CO2) to support manufacturing processes.
• Help develop, implement, and improve preventative maintenance programs for facility systems.
• Coordinate inspections, servicing, and repairs with vendors and service providers.
• Support planned shutdowns, power outages, and equipment…
