• Ensure layouts allow proper workflow, segregation of clean/dirty areas, and ease of maintenance.

• Collaborate with microbiologists and quality assurance for validation protocols.

• HVAC System Design for Controlled Environments

• Specify and size HVAC equipment (AHUs, CRAC units, HEPA filtration) to maintain ISO classifications and pressure differentials.

• Model airflow patterns and temperature/humidity controls in Revit or comparable CAD software.

• Coordinate ductwork, diffusers, and exhaust systems with MEP teams to guarantee aseptic conditions.

• 3D Modeling & Documentation (Revit)

• Develop comprehensive Revit models for piping, equipment, and HVAC systems, ensuring clash detection and constructability.

• Produce clear, annotated construction drawings, isometric sketches, and material take-offs.

• Maintain organized drawing archives and version control in project management platforms.

• Cross-Functional Collaboration & Client Interaction

• Serve as the primary technical liaison between clients, architects, QA/QC teams, and construction contractors.

• Lead design review meetings, present key process concepts, and incorporate stakeholder feedback.

• Coach junior engineers and drafters, fostering a team environment of continuous learning.

• Regulatory Compliance & Best Practices

• Stay current on FDA, EMA, and WHO guidelines related to aseptic manufacturing, cleanroom design, and validation requirements.

• Integrate industry best practices for risk mitigation, maintaining design integrity for qualification/validation.

• Support commissioning, qualification, and start-up phases by providing as-built markups, punch lists, and technical troubleshooting.

Required Qualifications

• Education: Bachelor's or Master's degree in Mechanical Engineering, or a related field (Pharmaceutical Engineering focus preferred).

• Experience:

• Minimum 10 years designing process systems for pharmaceutical or biotech facilities.

• Proven track record with P&ID development, lab design, and aseptic line projects.

• Hands-on experience specifying and modeling HVAC systems for controlled environments.

• Technical Skills:

• Expert proficiency in Revit (3D modeling, clash detection, families).

• Strong background in AutoCAD or CADWorx for P&ID development.

• Familiarity with SmartPlant or AVEVA/E3D (bonus).

• Proficient in Microsoft Office Suite (Excel, Word, PowerPoint) for reporting and presentations.

• Regulatory Knowledge:

• Thorough understanding of GMP, FDA's 21 CFR Part 11/210/211, ISO 14644, and other cleanroom standards.

• Experience supporting commissioning and validation activities (IQ/OQ/PQ deliverables).

Professional & Personal Attributes

• People Skills & Communication:

• Exceptional verbal and written communication: able to explain complex technical concepts in a clear, down-to-earth manner.

• Collaborative mindset: enjoys mentoring junior staff, soliciting feedback, and building cross-disciplinary rapport.
