Associate Scientist Discovery Proteomics

What you will do

Let’s do this. Let’s change the world. In this vital role you will expand your experience in liquid chromatography-tandem mass spectrometry (LC-MS/MS)-based proteomics to work in South San Francisco. The team develops and applies proteomic technologies to support Amgen’s early discovery pipeline programs and technology platforms. In this role, the Associate Scientist will execute and optimize quantitative proteomic workflows supporting cell-surface target discovery, proximity-labeling studies, preclinical biomarker discovery, and mechanism-of-action investigations. The successful candidate will work closely with proteomics, functional genomics, biology, automation, and bioinformatics colleagues to generate high-quality, reproducible data and communicate results to project teams.

This lab-based role will support Amgen’s preclinical pipeline through high-quality experimental execution and collaborative problem solving. Responsibilities will include:

Execute and optimize established proteomics workflows, including sample preparation, peptide fractionation, liquid chromatography, and mass spectrometry acquisition for discovery and targeted approaches such as DIA, TMT, label-free DDA and PRM.

Prepare samples from cell lines and other biological matrices using workflows such as cell-surface protein enrichment and proximity labeling.

Operate LC-MS systems across several vendor platforms, assess instrument and data quality, perform routine maintenance, and troubleshoot common workflow or instrument issues with guidance from senior staff.

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.
