Senior Mechanical Systems Engineer (HVAC & Environmental Controls)

To maintain confidentiality and prevent direct search matches, I have rephrased the title to Senior Mechanical Systems Engineer (HVAC & Environmental Controls) and generalized the industry-specific references to High-Tech Production Facilities. This version emphasizes the technical sophistication of the cleanroom and abatement systems.

Senior Mechanical Systems Engineer (HVAC & Environmental Controls)

We are seeking an experienced Senior Mechanical Systems Engineer to spearhead the design, integration, and long-term operation of critical environmental control systems for a state-of-the-art manufacturing facility. This role is essential for maintaining the rigorous temperature, humidity, and particle-count standards required for high-precision production environments.

Initially based in the Tempe and Peoria, AZ area during the infrastructure and commissioning phase, you will transition into a permanent leadership role as our flagship Peoria facility moves into full-scale factory operations.

Key Responsibilities

System Design & Project Lifecycle

• Technical Oversight: Collaborate with design consultants to ensure all mechanical and airflow requirements are met for cleanroom environments, administrative spaces, and specialized exhaust systems.

• Commissioning & Startup: Lead equipment preparation and operational testing; resolve technical abnormalities during the critical transition from construction to active production.

• Handover Management: Oversee the transfer of documentation, manuals, and standard operating procedures from the build team to the sustaining engineering team.

Operational Excellence & Abatement

• Specialized Systems: Provide advanced engineering support for Make-Up Air (MUA) units, Recirculating Air Units (RCUs), acid scrubbers, and complex solvent abatement (RCTO) systems.

• Environmental Stability: Manage "Out-of-Control Action Plan" (OCAP) conditions, ensuring cleanroom temperature, humidity, and pressure levels remain within strict tolerances.

• Infrastructure Support: Direct the maintenance and troubleshooting of office-side HVAC, including AHUs and VAV systems.

Sustaining Engineering & Optimization

• Capacity Planning: Conduct trend analysis and system evaluations to forecast production demands and identify necessary capital upgrades.

• Efficiency Initiatives: Partner with maintenance teams to implement energy-saving technologies and improve system reliability using FMEA and root cause analysis.

• Tool Integration: Review exhaust designs during the equipment hook-up phase and perform engineering inspections for all new production assets.

Candidate Profile

Essential Qualifications:

• Education: Bachelor’s degree in Mechanical Engineering or a related technical field.

• Proven Tenure: 5+ years of experience in HVAC engineering (design and operations), specifically within high-tech manufacturing, pharmaceutical, or aerospace environments.

• Technical Mastery: Deep understanding of chilled water systems, cooling towers, and ISO cleanroom standards.

• Documentation Skills: Expert ability to interpret engineering specifications and proficiency in AutoCAD, Revit, and Bluebeam.

• Problem Solving: Strong analytical skills with a focus on reliability engineering and troubleshooting complex airflow systems.

Physical & Operational Readiness:

• Field Capability: Ability to climb ladders, work at elevation, navigate confined spaces, and work in varying weather conditions.

• Physical Fitness: Regularly able to lift 50 lbs and maintain medical qualification for respirator use.

• Professional Credentials: A Professional Engineering (PE) license is a significant advantage.

Location & Mobility:

• Ability to work onsite at Tempe and Peoria locations, with hybrid flexibility available as the project matures.
