About the Role

We are looking for a flexible analytical scientist within our growing tRNA CMC Group. The candidate will work internally with discovery and development scientists on the development of fit-for purpose characterization methods for the analysis and QC of preclinical tRNA materials with a special focus on lipid nanoparticle (LNP) formulations. In addition, you will work with external development partners on more extensive analytical methods for the characterization of materials for clinical manufacturing. The role will also be responsible for the support of the internal analytical lab instrument infrastructure and capabilities.

Core Responsibilities

· Characterization of LNP formulations (Size/ PDI, charge, tRNA quantitation assays, osmolality, etc.) including the design and execution of stability protocols.

· Characterization of tRNA oligonucleotides in conjunction with their LNP formulation, degradation products, and accompanying synthesis/formulation impurities by a variety of analytical techniques (i.e., UHPLC, LC-MS, Q-TOF, IEX, SEC, CGE, CD, Karl Fisher, and elemental analysis) utilizing Agilent chromatography instruments and associated software.

· Development, qualification and validation of purity determination, stability indicating, and physical measurement methods of analysis.

· Support the transfer of technology to external CROs and establish QC practices to enable eventual cGMP manufacturing that include amidite characterization, impurity identification and quantification, and process sample analysis for troubleshooting and development.

· Source, explore, and implement latest separation science and technologies for the purification of oligonucleotides and their conjugates (carbohydrate, lipid, peptide, protein)

· Identify and exploit new scientific concepts.

Qualifications and Skills

· PhD with 5+ years of direct experience (MS with 11+ yrs) in analytical development for lipid nanoparticle formulations and strong preference for history with oligonucleotide/RNA therapeutics (Analytical Chemistry, Pharmaceutical Sciences, Chemistry, or a related discipline)

· Hands-on experience with reversed phase and size exclusion chromatography method development with dynamic light scattering, evaporative light scattering or charged aerosol detection for the characterization of lipid nanoparticle formulations.

· Ability to learn and apply technical knowledge to meet changing project needs and balance multiple activities, prioritize and handle ambiguity.

· Excellent written and verbal communication skills with emphasis on documentation of experimental work and effective presentations.

· Knowledge of statistical software and applications for design of experiments and process modeling is a plus.

What We’ll Offer You

· Comprehensive, competitive healthcare and dental coverage through Blue Cross Blue Shield, vision coverage through VSP, family leave, paid time off, 401k retirement plan, disability and life insurance, and fully covered parking/commuter benefits.

· A dynamic early-stage work environment and highly interdisciplinary, talented, and collaborative team.

· Participation in an unprecedented opportunity to advance a single tRNA medicine to restore disrupted protein production, regardless of target, for thousands of diseases with the same underlying genetic mutation.

· Professional growth opportunities through mentoring, training, immersion in cross-functional projects, and opportunities to learn and try new things.
