Responsibilities

• Design, express, and purify recombinant protein and biologics (e.g., cytokine, antibodies, multi-specific formats, fusion proteins) to support PharmaEssentia’s research and early development programs.
• Lead analytical, developability, and stability assessment of biologics using techniques such as SDS-PAGE, HPLC, SEC, BLI/SPR, and ELISA to assess purity, binding, and CMC properties.
• Develop, optimize, and troubleshoot protocols for biologics generation and analytics workflows, ensuring high-quality and reproducible results.
• Provide technical expertise, guidance, and mentorship to junior team members, cultivating an environment of continuous learning and growth.
• Participate in project teams, identify and prioritize critical experiments to accelerate the drug discovery programs, and contribute to an innovative product portfolio with diverse modalities.
• Constantly assess and implement new technology to the existing workflow to improve efficiency and to enhance biologics production and analytical capabilities.
  
  

Qualification

• PhD in Biochemistry, or related biological science disciplines with 2+ year post-graduate experience in Biologics discovery and development function.
• Hands-on experience in biologics production using mammalian expression systems (e.g., transient/stable transfection in HEK293 or CHO cells).
• Proficiency in protein purification techniques including affinity, ion exchange, and size-exclusion chromatography.
• Expertise in protein analytical techniques such as UV-VIS, SEC-HPLC, RP-HPLC, CE-SDS, cIEF/IEX DLS, and DSF.
• Experience in protein purification using automated (AKTA) systems and purification of constructs with appropriate tags.
  
  

Preferred Qualification

• Hands-on experience with antibody engineering, multi-specific antibody formats, or Fc-fusion protein generation.
• Knowledge of developability assessments and early characterization assays for biologics.
• Familiarity with bioconjugation, purification and characterization processes relevant to ADC development and manufacturing.
• Experience using automation platforms for high-throughput protein expression, purification, and analytical workflows.
