Document instrument performance, organize regular maintenance, and coordinate with service engineers during maintenance and troubleshooting activities.

Lead and execute characterization activities to evaluate and elucidate critical quality attributes of mRNA, such as 5’ capping efficiency, 3’ polyA tail distribution, and oligonucleotide sequence mapping.

Provide analytical support for cross-functional teams, including formulation development, upstream/downstream process development, and manufacturing to solve drug development challenges.

Proactively advance LC-MS characterization of biotherapeutics by developing innovative techniques that address evolving developmental needs and improve operational efficiency.

Independently conduct sample preparation and LC-MS analyses in compliance with SOPs, and document experimental procedures and results in electronic laboratory notebook (ELN).

Author and review regulatory submission documents, such as IND and comparability study.

Qualifications

Ph.D. in Analytical Chemistry, Biochemistry, Pharmaceutical Sciences, or a closely related field with 0-3 years of industry experience.

Previous experience with mRNA, oligonucleotide, antibody, and LNP analysis by LC-MS is a strong plus.

Experience in mRNA 5’ capping and 3’ polyA tail LC-MS analysis is preferred.

Proficient in operating and maintaining mass spectrometry equipment, particularly LC-MS systems, and have experience in troubleshooting and maintaining LC-MS instruments, including tasks like changing and cleaning interfaces.

Experience with LCMS data acquisition and analysis software, such as XCalibur, Protein Metrics, FreeStyle, Skyline, BioPharma Finder, and MassLynx.

Organized, detail-oriented, and committed to maintaining proper documentation.

Work independently while also collaborating effectively with a team of experts.

Hands-on experience with additional analytical techniques relevant to mRNA or LNP analysis is a plus.

Strong presentation and communication skills with the ability to explain data to technical and non-technical audiences.

How we calculate "similar"

No black box, no LLM guesswork: a deterministic score built from four normalized attributes. Here's this role's own peer group at different match levels, so you can see the mechanism, not just the result.

Every comparison starts from the same 100-point budget: 25 for working in the same function, 40 for the same therapeutic area, 20 for the same or adjacent seniority, 15 for the same country. A dimension we can't confirm on both sides contributes nothing, never a guess, never a free pass.

Unmatched or unknown dimensions score exactly the same: 0 points, never a partial guess. A role we know almost nothing about beyond its function bottoms out at 25%; it never inflates to 100% just because there's little to compare against. Seniority uses a defined ladder (Associate → Manager → Associate Director → Senior → Principal → Director → Senior Director → Executive/VP) so "Director" and "Senior Director" count as adjacent, but "Director" and "Executive/VP" do not.
