Senior Mechanical Engineer- HVAC Design (Controlled Environments- clean rooms )

Locations : Carolina or Michigan can be remote and client will also cover relocation Role Overview Our client is seeking a Senior Mechanical Engineer to lead design strategies for controlled environments including cleanrooms, laboratories, and mission-critical spaces. In this role, you will mentor engineering teams and develop advanced mechanical systems with an emphasis on performance, precision, sustainability, and regulatory compliance. You will collaborate across disciplines and markets to shape environments that support human health, technology, and innovation. Key Responsibilities Lead mechanical engineering design for complex projects with advanced environmental control needs, including cGMP-regulated facilities and ISO-certified spaces. Develop custom mechanical and utility systems leveraging expertise in psychrometrics, temperature/pressure/humidity control, dehumidification, high-efficiency filtration, and specialty gas/water/process piping. Oversee conceptualization and development of cutting-edge HVAC, energy, and mechanical systems, incorporating emerging technologies and smart controls. Conduct comprehensive energy modeling and performance simulations to guide design decisions and promote energy efficiency and regenerative principles. Write detailed control sequences, control diagrams, system scopes, custom specifications, and performance-based design objectives. Guide Revit modeling best practices, including sloped sanitary/process piping design, elevation coordination, branch tie-ins, and inheritance functions. Coordinate with clients, contractors, cross-functional teams, and stakeholders throughout the project lifecycle to ensure design goals are met and risks are minimized. Mentor junior staff, lead technical reviews of critical deliverables, and provide expert feedback that adds value. Serve as Subject Matter Expert (SME) in controlled environments for highly complex and innovative designs. Facilitate field inspections of major projects and lead Lessons Learned sessions to align construction with design intent. Contribute to firm-wide innovation by evaluating new technologies, sharing knowledge, and recommending improvements based on field and industry experience. Specialized Engineering Knowledge Extensive knowledge of mechanical system technologies, including current and anticipated future advances in controlled environments. Deep understanding and application of psychrometric charts for humidity/dewpoint control and dehumidification system sizing. Practical sizing criteria for ductwork and piping (pressure drop and velocity guidelines) based on experience rather than software defaults. Design for redundancy, mission-critical reliability, and high-performance filtration/utility systems. Required Qualifications Bachelor's degree in Mechanical Engineering or related field. Licensed Professional Engineer (P.E.). 10+ years of post-graduation professional engineering experience. Proficiency in Revit and AutoCAD for advanced modeling and documentation standards. Demonstrated experience with psychrometric analysis, dehumidification control, redundancy planning, and mechanical systems in mission-critical or regulated facilities. Preferred Qualifications Direct design experience in controlled environments such as biotechnology, pharmaceutical, medtech, sterile manufacturing, semiconductor, battery, aerospace, or data centers (strongly preferred). Experience writing design fee estimates, technical specifications, and control diagrams. Familiarity with pressure drop/velocity criteria for duct/piping sizing and sanitary piping modeling challenges. Client-facing experience translating requirements into project plans and fostering strong relationships. This job description is confidential and intended solely for prospective candidate review.
