What You'll Work On

We are seeking an Oligonucleotide Scientist with responsibilities spanning Process Development, Manufacturing Development, and Scale-Up of solid-phase oligonucleotide synthesis. In this role, you will execute, research, develop and optimize oligonucleotide processes across the full development lifecycle - from early feasibility runs through process characterization, tech transfer and scale-up. You will work hands-on with automated synthesizers, develop and refine synthesis cycles, troubleshoot complex chemistries, and drive scale-up from nano-gram process development to micro/milli-gram scale-up. This is a high-impact role for a scientist who enjoys solving problems at the intersection of organic chemistry, analytical science, and process engineering. The scientist will also Independently develop data presentations for use within organization.

• Design and execute solid-phase oligonucleotide synthesis on automated synthesizers (e.g., AKTA Oligosynt, AKTA Pilot 100, GE/Cytiva flow-through platforms) using phosphoramidite chemistry.

• Develop, optimize, and document synthesis cycles, including coupling, capping, oxidation/sulfurization, and detritylation steps, and tune cycle parameters (reagent equivalents, contact times, flow rates) for each scale and chemistry.

• Support scale-up from process development (PD) to engineering and GMP production batches, including selection of solid supports (CPG, polystyrene, UnyLinker), columns (e.g., SYC, FineLINE), and reagent footprints.

• Synthesize complex modified oligonucleotides, including phosphorothioate (PS) backbones, 2'-OMe, 2'-MOE, LNA, and other relevant modifications.

• Characterize crude and purified product by analytical UPLC, IEX-HPLC, RP-HPLC, and LC/MS; interpret mass spectra to identify and quantify related impurities (n1, n+1, depurination, longmers, shortmers, branched species, oxidation/sulfurization products).

• Troubleshoot synthesis failures and impurity profiles, drive root-cause investigations, and implement process improvements.

• Author and review technical documents - protocols, batch records, development reports, deviation investigations, and tech-transfer packages.

• Partner cross-functionally with Analytical Development, Downstream Processing/Purification, Quality, Manufacturing, and Regulatory teams.

• Maintain a safe, clean, and compliant lab environment in accordance with company SOPs and applicable cGMP/ICH guidelines.

Required Qualifications

• Hands-on experience with solid-phase oligonucleotide synthesis using phosphoramidite chemistry.

• B.S in biological or physical sciences, or mathematics; with minimum of 4 yrs.

• M.S. w/ minimum 2 yrs experience. Or Ph.D.

• Direct experience operating at least one automated oligonucleotide synthesizer.

• Working knowledge of common solid supports (CPG, polystyrene, UnyLinker) and the relationship between support loading, column geometry, and synthesis scale.

• Hands-on experience with LC/MS for oligonucleotide characterization, with demonstrated ability to identify and quantify related impurities (n1, n+1, depurination, longmers, shortmers, branched species, oxidation/desulfurization products) and to perform sequence confirmation by MS/MS fragmentation.

• Familiarity with complementary oligonucleotide analytical techniques: UPLC/HPLC (RP and IEX) for purity assessment.

• Strong scientific writing and documentation skills.

• Ability to work independently, prioritize multiple projects, and meet deadlines in a fast-paced environment.

Preferred Qualifications

• Experience in a GMP or pharmaceutical API manufacturing environment.

• Experience operating Waters LC/MS systems (e.g., Xevo, SYNAPT, ACQUITY-MS) and associated data-processing software (MassLynx, UNIFI).

• Experience with scale-up (nmol to mmol scale) and tech transfer of oligonucleotide processes.

• Familiarity with conjugated oligonucleotides (e.g., lipid conjugates).

• Experience with downstream operations - cleavage/deprotection, IEX or RP preparative purification, ultrafiltration/diafiltration, and lyophilization.

• Familiarity with statistical tools (JMP, Minitab) and Design of Experiments (DoE).

• Awareness of regulations and standards affecting IVDs and Biologics

• Basic computer skills - able to learn new computer programs
