Membrane Separation Engineer Jobs in Tennessee (NOW HIRING)

Membrane Separation Engineer information

What does a membrane separation engineer do?

A Membrane Separation Engineer specializes in designing, developing, and optimizing processes that use membranes to separate substances in liquids or gases. They work in industries such as water treatment, pharmaceuticals, food and beverage, and chemical manufacturing, focusing on filtration, purification, and concentration processes. Their responsibilities include selecting appropriate membrane technologies, troubleshooting system performance, and ensuring efficient and sustainable operation. They also stay updated on advancements in membrane materials and system design to improve process efficiency and reduce costs.

What are the key skills and qualifications needed to thrive as a membrane separation engineer?

To thrive as a Membrane Separation Engineer, you need a solid background in chemical engineering, materials science, or a related field, often with a relevant bachelor's or master's degree. Familiarity with membrane fabrication techniques, characterization tools (such as SEM, FTIR), and simulation software like COMSOL or Aspen Plus is typically required. Strong problem-solving, project management, and teamwork skills distinguish top professionals in this niche. These competencies are crucial for designing efficient membrane systems, optimizing separation processes, and ensuring project success in research or industrial environments.

What are the primary challenges membrane separation engineers face when scaling up laboratory processes to full-scale industrial applications?

Membrane Separation Engineers often encounter challenges related to membrane fouling, maintaining consistent performance, and optimizing operational costs when transitioning from lab-scale experiments to industrial-scale systems. Issues such as feed variability, cleaning protocols, and system integration with existing plant operations become more complex at larger scales. Successful engineers must collaborate closely with process engineers, maintenance teams, and quality assurance specialists to troubleshoot, adapt designs, and ensure regulatory compliance throughout scale-up.

What is the difference between Membrane Separation Engineer vs Process Engineer?

Job description

Requisition Id 16936
Overview:
We are seeking a postdoctoral research associate who will focus on membrane and sorbent materials and processes for advanced separations and purification applications. This position resides in the Soft Materials and Membranes Group in the Chemical Sciences Division, Physical Sciences Directorate (PSD), at Oak Ridge National Laboratory (ORNL).
As part of our team, you will work on developing energy efficient and cost-effective materials and processes for energy applications. The successful candidate will focus on problems related to the separation and recovery of critical materials, gas separation, and biomass based chemical and fuel precursors. Selected candidate will be responsible for developing new and exciting ideas, building collaboration within and outside ORNL, and executing the project from idea stage to eventually generating quantifiable outcomes such as publications and invention disclosures.
Major Duties/Responsibilities:
  • Collaborate with a multidisciplinary team to advance separation science and technologies for energy applications.
  • Support research and program-development activities in advanced separation and purification, including the recovery of critical materials used in magnets, batteries, and semiconductors from mined resources and electronic waste, as well as separations for bioenergy applications.
  • Develop new research directions and contribute to proposals for external funding.
  • Communicate research findings through technical reports, conference presentations, and timely publications in peer-reviewed journals.
  • Prepare invention disclosures and contribute to patent applications, as appropriate.
  • Comply with applicable environmental, safety, health, and quality requirements.
  • Demonstrate a strong commitment to ethical conduct and ORNL's organizational values.
  • Deliver ORNL's mission by aligning behaviors, priorities, and interactions with our core values of Impact, Integrity, Teamwork, Safety, and Service. Promote equal opportunity by fostering a respectful workplace - in how we treat one another, work together, and measure success.

Basic Qualifications:
  • A PhD in chemical engineering, chemistry, environmental science and engineering, materials science and engineering, or a related field completed within the last 5 years.

Preferred Qualifications:
  • A strong foundation in separation and purification science, materials chemistry and engineering, polymer chemistry, or related disciplines.
  • Hands-on experience designing, synthesizing, fabricating, characterizing, and evaluating materials for separation applications.
  • Research experience in one or more of the following areas:
    • membrane- or sorbent-based separation and purification;
    • hollow-fiber or spiral-wound membrane-module fabrication and membrane-process scale-up;
    • filtration, solvent or liquid-liquid extraction, solid-liquid or gas-liquid separation, membrane contactors, adsorption, or packed-column systems;
    • extraction, separation, and purification of critical materials, including rare-earth elements and materials used in semiconductor and battery technologies; or
    • separation technologies for bioenergy applications.
  • A record of productive and creative research demonstrated through peer-reviewed publications, presentations, patents, or other relevant research outputs.
  • Excellent written and oral communication skills.
  • Motivated self-starter with the ability to work independently and to participate creatively in collaborative teams across the laboratory.
  • Ability to function well in a fast-paced research environment, set priorities to accomplish multiple tasks within deadlines, and adapt to ever changing needs.

Special Requirements:
For employment at Oak Ridge National Laboratory (ORNL), a Real ID compliant form of identification will be required. Additionally, ORNL is subject to Department of Energy (DOE) access restrictions. All employees must also be able to obtain and maintain a federal Personal Identity Verification (PIV) card as mandated by Homeland Security Presidential Directive 12 (HSPD-12) and Department of Energy (DOE) Order 473.1A, which requires a favorable post-employment background investigation.
To obtain this credential, new employees must successfully complete and pass a Federal Tier 1 background check investigation. This investigation includes a declaration of illegal drug activities, including use, supply, possession, or manufacture within the last year. This includes marijuana and cannabis derivatives, which are still considered illegal under federal law, regardless of state laws.
