Scientist LC-MS/MS Bioanalytical

What you will do

Let’s do this. Let’s change the world. In this vital role you will independently support the design, development, validation, and implementation of robust quantitative LC-MS/MS bioanalytical methods and experiments for small molecules and perform bioanalysis for discovery, GLP preclinical and regulated clinical studies.

The position is lab-based, and additional responsibilities will include critically reviewing and interpreting scientific data and results, report generation, project management, communication of results, data presentations, supporting automation efforts, and keeping current with technology development.

The role will involve multidisciplinary collaborations with scientists across research and development at Amgen and may include contribution to key/critical teams and participation in national scientific meetings.  This position is also responsible for providing scientific results that may support the generation of publications, patents or regulatory submissions.  Familiarity with peptide and protein quantitation by hybrid LC-MS/MS methodology and affinity capture techniques a plus.

Key Responsibilities:

• Develop and implement LC-MS/MS bioanalytical methods with quick turnaround times.  Conduct small molecule bioanalysis of parent and metabolites in non-clinical and clinical samples from various matrices (plasma, urine, CSF, tissues).

• Perform biological sample extraction using protein precipitation, SPE, and LLE.

• Generate complete, accurate, and concise documentation using LIMS and electronic laboratory notebook systems.

• Ensure bioanalytical data meets regulatory expectations for global submissions by maintaining accurate records and staying current with industry guidelines.

• Author study reports, standard operating procedures, analytical methods, memos, scientific publications, and other regulatory compliant documents.

• Communicate bioanalytical data to key discovery and development teams, contribute to scientific publications, and present at professional meetings.

• Comply with safety guidelines and site-specific procedures which include but are not limited to the completion of training on assigned tasks, maintenance of training records, laboratory documentation, and following detailed SOPs and other written procedures.

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.
