Scientist/Senior Scientist, Analytical Sciences

Company Summary: Korro is a biopharmaceutical company focused on developing a new class of genetic medicines for both rare and highly prevalent diseases using its proprietary RNA editing platform. Korro is generating a portfolio of differentiated programs that are designed to harness the body’s natural RNA editing process to effect a precise yet transient single base edit. By editing RNA instead of DNA, Korro is expanding the reach of genetic medicines by delivering additional precision and tunability, which has the potential for increased specificity and improved long-term tolerability. Using an oligonucleotide-based approach, Korro expects to bring its medicines to patients by leveraging its proprietary platform with precedented delivery modalities, manufacturing know-how, and established regulatory pathways of approved oligonucleotide drugs. Korro’s lead program is Alpha-1 Antitrypsin Deficiency (AATD). Korro is based in Cambridge, Massachusetts.

We are collaborative and united by a common mission. We are building a company with extraordinary people with an audacious vision to create transformative genetic medicines for prevalent diseases. Our values - Rewrite the future, On the Cutting Edge, Better Together, Dynamically Different, Kindness and Integrity form the fabric of the organization. They are reinforced daily and serve as key dimensions in the hiring process to help us ensure that Korro is a magnet for outstanding talent and a great place to work. Join us as we redefine what's possible in genetic medicine and work to make a lasting impact on human health.

Position Summary:

Korro Bio is seeking an analytical Scientist to join the growing CMC team. You will focus on the development, optimization, and validation of analytical methods for RNA-based therapies. This role will support and manage - the quality and stability of drug substances and drug products throughout the development lifecycle. You will work closely with cross-functional teams and external partners to ensure that analytical data supports regulatory filings and clinical trial progression.

• Develop and optimize analytical methods for the characterization, quantification, and release of RNA-based drug substances and products.
• Perform routine and non-routine testing, including HPLC, UV-Vis, mass spectrometry, and other relevant techniques, to assess product quality and stability.
• Support analytical method validation, transfer, and troubleshooting to ensure compliance with cGMP standards.
• Collaborate with the Process Development and Quality Control teams to ensure seamless integration of analytical methods into manufacturing workflows.
• Analyze, interpret, and present complex data to cross-functional teams and senior management.
• Author and review technical reports, protocols, SOPs, and sections of regulatory filings (IND, IMPD etc.).
• Assist in managing external analytical collaborations with CROs and CMOs, ensuring data quality and timelines are met.
• Stay current with emerging analytical technologies and apply innovative solutions to improve method robustness and efficiency.
• Support investigations and root cause analyses for any out-of-specification (OOS) results, deviations, or process failures.

• PhD in Analytical Chemistry, Biochemistry, Molecular Biology, or related field; or MS with 5+ years of relevant industry experience.
• 3+ years of hands-on experience in analytical method development for biologics, with experience in RNA therapeutics preferred.
• Expertise in chromatographic (e.g., UPLC -UV, and UPLC-MS) and spectroscopic techniques (e.g., UV-Vis), with a strong understanding of method validation requirements. Experience with fluorescence, IR and NMR is a plus.
• Familiarity with cGMP and ICH guidelines for analytical development and quality control of biologics.
• Experience with stability studies, impurity profiling, and degradation pathways.
• Strong analytical skills with the ability to troubleshoot and solve complex technical problems.
• Excellent written and verbal communication skills, with experience drafting technical reports and regulatory documents.
• Ability to work collaboratively in a fast-paced environment and manage multiple projects simultaneously.

Benefits:  Korro offers competitive compensation, including equity-based compensation, and a comprehensive benefits package that includes medical, dental, vision, 401(k) retirement plan, life insurance, a dependent care flexible spending account and a Company-funded health savings account and free parking.
