  • Years of experience should be in the industry and not just from school.

 

Essential qualifications:

  • Bachelor’s or Master’s degree in Protein Biochemistry/Biochemistry preferred, or related field.
  • With a Bachelor's Degree - At least 3-5 years of hands-on laboratory experience (industry).
  • With a Master's Degree - At least 1–3 years of hands-on laboratory experience (industry).
  • Experience with recombinant protein production, purification, and characterization.
  • Protein characterization techniques (e.g. SDS-PAGE, Western Blots, endotoxin testing, HPLC, BLI (Octet) or SPR (Biacore))
  • Experience in FPLC protein purification using AKTA systems and Unicorn software (e.g. affinity chromatography, SEC, and IEX)
  • Strong organizational and documentation skills.
  • Ability to work independently and as part of a team
  • Excellent communication and problem-solving skills.
  • A creative, problem-solving, collaborative, and goal-oriented mindset

  • Experience in plate based functional assays (ELISA/MSD, functional assays, enzyme kinetics, chromogenic/fluorescent readouts, etc.)
  • Experience with protein bioconjugation and conjugate purification
  • Experience with oligonucleotides and related methods a plus
  • Experience using Benchling (eLN)

 

Key Responsibilities:

  • Support expression, conjugation, purification and characterization of proteins
  • Develop and conduct biophysical and functional assays to validate various protein designs
  • Perform plate-based assays to analyze samples downstream from in vivo studies
  • Analyze, integrate and interpret data from multiple sources
  • Diligently document work in digital systems and regularly communicate results in team and group settings
  • Prepare reagents, solutions, and samples for analysis, including samples collected from in vivo studies (e.g. tissue homogenization and protein extraction).
  • Assist in method development, validation, and troubleshooting.
  • Ensure compliance with safety regulations and good research practices
  • Work collaboratively in a team environment and manage priorities to achieve our goals
