• A proactive mindset with a passion for innovation and sustainability. 

• Draftsight/AutoCAD 2D CAD experience is a plus. 

Outstanding Candidates Will Have: 

• Technical Expertise: Deep understanding of mechanical systems engineering principles and purification technologies, with hands-on experience in design and systems optimization, complemented by advanced analytical and simulation capabilities.  Advanced understanding of fluid dynamics. Experience with process simulation software. 

• Adaptability: Ability to adapt to new challenges and technologies and a willingness to learn and grow within the role. 

• Attention to Detail: Meticulous attention to detail in design, testing and documentation to ensure high-quality outcomes. 

Key Success Factors: 

• Adherence to project schedules and timely completion of design, testing and implementation phases. 

• The thoroughness and clarity of documentation produced, ensuring it meets industry standards and is useful for future references. 

• Contributions to the development of new technologies or improvements to existing systems. 

• Effective teamwork and communication with other cross functional teams, global engineering and stakeholders.
