What are some common challenges Membrane Engineers face when scaling up from lab-scale to industrial-scale membrane processes?

Membrane Engineers often encounter challenges related to membrane fouling, maintaining consistent performance, and ensuring cost-effective operation when scaling up from laboratory to industrial settings. Issues such as variations in feed water quality, larger system hydraulics, and the need for robust cleaning protocols become more pronounced at scale. Successful engineers collaborate closely with process engineers, maintenance teams, and quality control to troubleshoot and optimize systems for reliability and efficiency. Being proactive in addressing these challenges is key to the role and can lead to significant process improvements.

What is a membrane in engineering?

In engineering, a membrane is a thin, selective barrier that separates two environments and allows certain substances to pass through while blocking others. Membranes are used in processes such as filtration, desalination, and gas separation, often requiring knowledge of materials science and process engineering. Membrane engineers design, develop, and optimize these systems to improve efficiency and performance.

What are membrane engineers?

Membrane engineers are professionals who design, develop, and optimize membrane-based systems for applications such as water purification, gas separation, and chemical processing. They work with various membrane materials and processes to achieve efficient separation of substances at the molecular or ionic level. Membrane engineers often collaborate with chemists, material scientists, and process engineers to improve membrane performance and durability. Their expertise is crucial in industries like wastewater treatment, pharmaceuticals, food processing, and energy.

What are the key skills and qualifications needed to thrive as a Membrane Engineer, and why are they important?

To thrive as a Membrane Engineer, you need a strong background in chemical engineering, materials science, or environmental engineering, often supported by a relevant degree and experience in membrane technology. Familiarity with simulation software (such as COMSOL Multiphysics), laboratory instrumentation, and industry standards or certifications like ISO 9001 is highly valuable. Strong analytical thinking, problem-solving abilities, and effective communication skills help set candidates apart in this role. These competencies enable the development, optimization, and implementation of advanced membrane systems essential for water treatment, gas separation, and sustainable industrial processes.

What engineers make 200,000 a year?

Senior engineers in specialized fields such as petroleum, aerospace, or software engineering often earn $200,000 or more annually, especially with extensive experience, advanced skills, and relevant certifications. Roles in management or with significant technical expertise tend to have higher compensation levels.

Job description

The Company

Dexcom Corporation (NASDAQ DXCM) is a pioneer and global leader in continuous glucose monitoring (CGM). Dexcom began as a small company with a big dream: To forever change how diabetes is managed. To unlock information and insights that drive better health outcomes. Here we are 25 years later, having pioneered an industry. And we're just getting started. We are broadening our vision beyond diabetes to empower people to take control of health. That means personalized, actionable insights aimed at solving important health challenges. To continue what we've started: Improving human health.

We are driven by thousands of ambitious, passionate people worldwide who are willing to fight like warriors to earn the trust of our customers by listening, serving with integrity, thinking big, and being dependable. We've already changed millions of lives and we're ready to change millions more. Our future ambition is to become a leading consumer health technology company while continuing to develop solutions for serious health conditions. We'll get there by constantly reinventing unique biosensing-technology experiences. Though we've come a long way from our small company days, our dreams are bigger than ever. The opportunity to improve health on a global scale stands before us.

Meet the team:

As a key member of the material science group within Dexcom's research and development organization, the Staff membrane and formulation scientist is responsible for developing and validating novel membrane designs and formulations to support next generation biosensor products.

The Staff Scientist is expected to have clear understanding of the technical and business challenges associated with medical device material component product development and will be responsible for developing, validating, and implementing technical solutions that meet the objectives. In this capacity, the staff scientist will work cross functionally to drive the creation and maintenance of design requirements, down select formulation chemistry, develop and validate design/process to final specification, identify and mitigate risks, interface with external partners and collaborate with internal stake holders to drive the project to completion.

Where you come in:

  • You will define and develop formulation strategies for new biosensing modalities, maintaining relevant domain expertise and driving formulation excellence

  • You will design and develop thoughtful DOE and testing protocols conducive to generation of rapid insights on structure-function behavior

  • Plan and execute experiments, identify critical variables and design trade-offs, screen and down-select formulation candidates for form-fit-function on targeted applications while maintaining a manageable business / commercial risk profile

  • Document experimental details and analysis, author technical reports, present results to a wide audience of stakeholders, including progress reports, design reviews and phase exits

  • Verify that performance objectives have been met via pre-clinical and clinical evaluations of novel designs

  • Design and develop formulation-related validation protocols such as formulation process, formulation pot-life and shelf-life, lead the validation execution and author final reports

  • Identify, procure, and qualify critical raw materials and manage vendors to support formulation development and commercialization
