The Research Associate II/III will be responsible for executing small-scale protein expression and automated purification workflows using liquid handling robotics. This role supports weekly production goals by processing a defined list of plasmids, delivering quantified, pure protein for downstream applications. The ideal candidate combines strong technical skills in molecular biology and protein biochemistry with attention to detail and a collaborative mindset.

As part of our team, your core responsibilities will be: 

+ Perform recombinant protein expression in bacterial systems (e.g., E. coli) following established protocols.

+ Operate and maintain liquid handling robots and other laboratory automation platforms for protein purification.

+ Execute purification techniques including affinity, ion-exchange, and size-exclusion chromatography (manual and automated).

+ Quantify protein yield and purity using standard analytical methods (e.g., UV/Vis, SDS-PAGE, Western blot).

+ Maintain accurate laboratory records, batch documentation, and inventory of plasmids and reagents.

+ Troubleshoot and optimize expression and purification protocols as needed.

+ Collaborate with scientists and engineers to refine workflows and support process improvements.

+ Communicate results clearly to team members and contribute to formal reports as required.

+ Adhere to safety and quality standards in all laboratory activities.

Qualifications

+ Bachelor’s or Master’s degree in Biology, Biochemistry, Molecular Biology, Biotechnology, or related field.

+ 2–6 years of relevant laboratory experience (Research Associate II: 2+ years; Research Associate III: 4+ years preferred).

+ Hands-on experience with E coli cell culture, transformation and protein expression

+ Protein purification, using AKTA systems.

+ Familiarity with molecular cloning, plasmid preparation, and basic molecular biology techniques.

+ Strong organizational skills and attention to detail.

+ Ability to follow SOPs and work independently within defined protocols.

+ Excellent communication and interpersonal skills; able to work effectively in a team environment.

+ Experience with data analysis and documentation in electronic lab notebooks is a plus.

+ Experience with troubleshooting and optimizing protein expression/purification workflows is preferred.

+ Familiarity with FPLC/HPLC systems and chromatography software is preferred.

+ Prior exposure to high-throughput or automated laboratory environments is preferred.

+ Ability to adapt to changing priorities and respond to new challenges is preferred.
