Overview of Role

ZwitterCo is seeking a motivated, versatile laboratory technician for its applications engineering lab in a rapidly expanding early stage cleantech company. The candidate will play an internal and, at times, customer-facing role in designing and running laboratory experiments that support ZwitterCo’s Applications Engineering, Field Engineering, and Sales departments. This will involve operating filtration and water treatment equipment from beaker- to benchtop- to pilot-scale. The role will be a critical part of successfully supporting the company’s commercial growth into new industrial applications, progressing key technical and commercial projects, and achieving its mission to treat and recycle industrial wastewater and create value from previously untapped waste streams.

Candidates with experience in laboratory operations, membrane filtration systems, water treatment, and basic analytical chemistry are particularly encouraged to apply.


Primary responsibilities include:

  • Designing laboratory experiments at beaker-, benchtop-, and pilot-scale to advance technical and sales projects.
  • Operating pretreatment, post-treatment, and membrane filtration equipment at benchtop and pilot-scale.
  • Running basic analytical chemistry in the lab (e.g. TSS, COD, UV-Vis, O&G).
  • Summarizing and communicating lab results to internal and external audiences, including customers.
  • Working with cross-departmental teams to devise experiments that meet project goals and track key performance indicators (KPIs) on membrane performance.
  • Advancing knowledge of operating criteria for specific ZwitterCo products in target industries.
  • Troubleshooting complex customer inquiries or equipment failures and providing recommendations for corrective actions with the support of cross-functional teams.
  • Drafting technical reports and presentations, including data tables, graphs, and analysis, for internal and external audiences.


  • A high school degree is required unless the candidate has extensive previous work experience in a comparable role.
  • An associate’s or bachelor’s degree in environmental science, chemistry, engineering, or similar STEM program is preferred.
