Each semester the Department of Chemical and Biological Engineering (ChBE) seeks undergraduate Course Assistants (CAs) to support faculty in CHEN classes. CAs work 1-10 hours per week depending on their availability and the course needs. These student hourly roles are filled on an as-needed basis each semester. 

Becoming a CA is a great way to:

  • Solidify your understanding of an academic subject
  • Get to know professors (helpful when looking for recommendations)
  • Improve your communication and leadership skills
  • Help your fellow students and professors
  • Earn $$$

CA tasks depend on the course and instructor but usually involve some mix of the following:

  • Grading of class material
  • Helping answer student questions at office hours
  • Leading recitation sessions
  • Answering student questions via email
  • Putting together homework questions/solutions


  • First Years and Sophomores: $15.50/hr
  • Juniors: $16.00/hr
  • Seniors: $16.50/hr


  • CHEN or CBEN undergraduate student
  • We strongly prefer students who have received an A or A- in the class, though those with a B+ will also be considered.

Student hourly positions are not permanent employees and hired on a semester-by-semester basis. This position is eligible for employee sick leave earned monthly on a prorated basis. The ChBE Department does not provide internships, Research Assistantship (RAs) or Teaching Assistantships (TAs).

Interested applicants for CA openings may email Professor Timothy Whitehead at timothy.whitehead@colorado.edu with the following information:

  • Subject line: "CHEN Course Assistant position"
