• Operate a variety of chromatography instruments and provide subject matter expertise to enable purity assessment and concentration validation of complex synthetic molecules, as well as develop fit for purpose walk-up methods to assess drug-linker reactivity.
• Optimize workflows that accelerate open access preparative-scale HPLC purification of synthetic intermediates and final compounds.
• Collaborate with the synthetic chemistry team to develop custom-tailored approaches for challenging separations.
• Ensure data is readily available to end-users and properly archived through cross-functional coordination with IT and data management teams.
• Interact with partners in development roles (e.g., process chemistry, GxP functions) to align strategies and ensure efficient data transfer as projects progress to IND-enabling studies.
• Actively participate in training colleagues on the proper use of new equipment and technologies.
• Adhere to all company safety, scientific record keeping, and compliance requirements.

• Extensive experience in maintaining UPLC-MS and preparative HPLC instrumentation and deployment of fit-for-purpose work flows.
• Demonstrated ability to work effectively in multi-disciplinary teams, learn new skills and proactively identify and address analytical challenges.
• Experience developing new analytical LC-MS methods for walk-up applications.
• Strong interpersonal skills and effective written/verbal communication.
• Enthusiasm to work within a team-oriented environment with accelerated timelines

PREFERRED QUALIFICATIONS:

• Experience identifying and implementing new technologies that facilitate analysis and purification of small molecules.
• Familiarity with Waters software, as well as preparatory and analytical UPLC systems and mass spectrometers.
• Experience maintaining and utilizing mass-directed preparative HPLC.
• Experience working with antibody analytics and/or quantitative bioanalytical analysis via HPLC-MS/MS.
• Experience with automation of parallel sample management and data processing, including basic programming skills
