Applications Engineer - Membrion

Membrion is a growing clean technology company transforming how industries manage wastewater. Our proprietary electro-ceramic desalination (ECD) technology helps industrial customers treat challenging wastewater streams, recover valuable resources, and reduce the environmental and financial costs of water treatment. Working across industries including semiconductor manufacturing, food and beverage, and consumer packaged goods, we're bringing innovative treatment solutions into real-world industrial operations.

We're looking for an Applications Engineer who can turn complex customer challenges into practical, technically sound treatment solutions.

Working closely with our Sales, Technology, Engineering, Product, and Customer Success teams, you'll evaluate customer wastewater processes, identify opportunities for improvement, and develop integrated treatment solutions that balance technical performance, cost, and operational realities.

Our projects typically range from $500,000 to $5 million, and no two applications are quite the same. You'll need to think creatively, understand how different processes and equipment work together, and develop solutions that can be successfully integrated into existing industrial facilities.

This is a role for someone who enjoys getting into the details, challenging assumptions, and taking ownership of problems through to resolution. You'll have the independence to manage your work, the support of an experienced technical team, and the opportunity to see your solutions put into practice.

What You Will Do

Understand the Customer Application

• Gather and evaluate wastewater analyses, operating data, treatment objectives, site constraints, and existing infrastructure through customer discussions, records, and site inputs.

• Identify data gaps, likely root causes, ECD applicability, and technical risks; define the additional information or testing needed to advance the opportunity.

• Establish a traceable design basis that clearly distinguishes verified data, assumptions, and uncertainties.

• Develop creative, practical treatment concepts that integrate ECD with appropriate pretreatment and downstream processes, considering existing customer equipment, infrastructure, and operational constraints.
• Prepare process flow diagrams, mass balances, preliminary P&IDs where appropriate, and equipment and membrane sizing.
• Evaluate treatment alternatives based on performance, recovery, utility requirements, capital and operating costs, and sensitivity to changing feed conditions.
• Translate bench-scale and pilot results into practical design inputs, collaborating with Technology and Engineering to address system integration, safety, constructability, and operability before customer commitments.

We're interested in Applications Engineers who bring strong technical judgment, curiosity, and a practical approach to solving problems. While experience in industrial wastewater treatment is particularly valuable, we recognize that relevant skills can be developed through different engineering backgrounds and career paths.

• Experience in applications engineering, process engineering, or a related technical role, ideally involving industrial water or wastewater treatment.
• Strong analytical and creative problem-solving skills, with the ability to evaluate complex technical challenges and develop practical solutions.
• An understanding of industrial processes, equipment integration, and the operational requirements of treatment systems.
• Knowledge of water chemistry, mass balances, treatment performance, fouling, scaling, and operating cost considerations.
• Ability to develop and review engineering calculations, process flow diagrams, technical specifications, and proposal documentation.
• Sound engineering judgment, including the ability to recognize incomplete information, challenge assumptions, and identify when further technical validation is required.
• Strong written communication skills and the ability to collaborate effectively with technical and commercial colleagues.
• A proactive, self-directed approach to work, with the ability to manage competing priorities and take ownership of deliverables.
• Comfort working in a collaborative, predominantly remote environment where communication, initiative, and follow-through are essential.

Experience That Would Be Particularly Valuable

• Direct experience with industrial wastewater treatment systems, particularly membrane processes such as UF, NF, RO, or related technologies.
• Experience designing, sizing, or specifying packaged process equipment, including skid-mounted or containerized systems.
• Hands-on experience with equipment commissioning, field startup, operational troubleshooting, or supporting equipment integration at customer facilities.
• Experience preparing technical proposals, process flow diagrams, preliminary P&IDs, or CAPEX/OPEX evaluations.
• Experience with industrial applications in semiconductor manufacturing, food and beverage, or consumer packaged goods.
• A background in chemical, environmental, mechanical, or related engineering disciplines.

We value practical experience and demonstrated capability over any particular educational pathway. Candidates with transferable experience and a willingness to learn are encouraged to apply.

• Love solving complex technical problems, especially when the answer isn't immediately obvious.
• Take initiative, work independently, and follow problems through to resolution.
• Can balance technical detail with practical commercial and operational considerations.
• Enjoy collaborating with people from different technical and commercial backgrounds.
• Want to see your engineering work translate into real-world environmental and operational impact.

Solve problems that matter. Industrial wastewater treatment is a complex challenge, and the solutions aren't always obvious. At Membrion, we're developing technology that helps industries treat difficult wastewater streams, recover valuable resources, and reduce their environmental impact. Your engineering work will have a tangible, real-world purpose.

Work with genuinely innovative technology. Our electro-ceramic desalination (ECD) technology is opening up new possibilities for industrial wastewater treatment. You'll work on challenging applications where conventional approaches don't always deliver, combining established engineering principles with creative thinking to develop better solutions.

See your ideas become reality. This isn't a role where your work ends with a calculation or a drawing. You'll help develop solutions that become real equipment, integrated into operating industrial facilities. You'll have opportunities to see your work in action and understand the impact of your engineering decisions.

Have the freedom to figure things out. We're a growing company, and we value people who take initiative, ask good questions, and find ways forward. You'll have the autonomy to own your work, the support of experienced colleagues, and the opportunity to make a meaningful contribution without layers of bureaucracy.

Work with people who care about getting it right. We're a collaborative team of engineers, scientists, and commercial professionals who bring different perspectives to the same challenges. We value curiosity, accountability, practical problem-solving, and people who are willing to roll up their sleeves and help each other succeed.
