Job Responsibilities

The mission of the Advanced Technology Solutions (ATS) group at ALaS Newport is to facilitate innovation of gas separation membranes and cartridges, including membrane manufacturing processes, through new product and process development.  This is achieved through strong competencies in polymer and membrane design, manufacture, characterization, modeling/simulations, and testing.  Technological improvements include the development of the next generation gas separation membranes and cartridges to meet market demand.  The ATS group also serves the manufacturing organization to troubleshoot plant operations as well as customer applications that employ ALaS membranes. 

The Membrane Scientist will provide technical expertise on a range of cross functional projects, including development of novel gas separation membrane materials, development of composite hollow fiber gas separation membranes and scale up of membrane manufacturing processes, while simultaneously supporting and implementing improvements to these processes and equipment.

At times the individual may be called to weigh in on issues related to the operations of these membranes at customer sites.  The individual may also support root cause determination and development of appropriate corrective and preventive actions.

Duties and Responsibilities 

  • Design and develop new and improved composite hollow fiber gas separation membranes
  • Provide technical support and guidance to Sales and Business Development teams
  • Scale up membrane manufacturing process and develop manufacturing procedures
  • Implement new and improved membrane manufacturing processes
  • Provide leadership in safety best practices as appropriate to product and process development, and related activities
  • Evaluate membrane separation performance in support of process development and field tests
  • Troubleshoot composite hollow fiber membrane manufacturing and implement improvements as required
  • Schedule and coordinate projects to align with deadlines, milestones and budgets



Qualifications & Competencies


  • MS in Chemical Engineering, with specialization in membrane gas separation processes (PhD preferred but not required)
  • Excellent communication skills
  • 5+ years of hands on experience in gas separation membrane development
  • Demonstrates strong process and operational safety behavior at all times. 
  • Ability to work independently and in small teams, in a way that enhances team dynamics.
  • Ability to lead and manage small to medium projects.
  • Individuals should expect to work in an office, lab, and/or manufacturing environment with modest and part-time support from lab technicians and operators.
  • Hands-on work in the lab and in a production environment as required to execute membrane and cartridge development projects, lead troubleshooting and root cause investigations, etc. 
  • Capable of clear and concise written and verbal communication through reports, status updates, presentations, etc.
  • Able to interface with customers, suppliers, and senior management to positively convey information.
  • Capable of maintaining ongoing and developing new relationships with key technical partners in ALaS, R&D, external contractors, technology partners, etc. 



  • Fluency in HYSYS and membrane process modeling
  • 5+ years experience in polymer QC, dope preparation, MEDAL technology platform fiber manufacturing processes (e.g., spinning, fiber dehydration, forming, potting, skiving, testing)
  • Expertise in hydrodynamics of coating processes
  • Hands-on capability to comprehensively evaluate and predict membrane performance.
  • A strong technical understanding of all Hollow Fiber Production Steps employed in a Manufacturing Plant. 
  • Stay abreast with technical reports and published literature; alert technical team of new developments, willingness to test out new concepts to improve performance, yield, etc.

Additional Information

Working Conditions

  • The individual’s working environment will vary depending on specific activities on any given day, but generally will rotate between office, laboratory, and membrane manufacturing facility areas.
  • The individual will be required to wear appropriate PPE as mandated by the facility.
  • Occasional business travel may be required (~5-10%) to Woburn MA facility or key suppliers, as appropriate.


This position is identified as “safety-sensitive” and is subject to random drug testing in accordance with the current Drug and Alcohol Policy and/or state law.
