Job Description. 

Cajal is seeking a Scientist, Quantitative Lipidomics, motivated by Cajal’s mission to develop new medicines for patients suffering with neurodegenerative disorders. We are a multi-disciplinary team of experienced scientists, combining state-of-the-art approaches in computational biology, functional genomics, high-throughput imaging, translational models, and drug discovery. In a short time, we have assembled a terrific team of talented, innovative, and passionate individuals to transform the field of neurodegeneration drug discovery. We aim to identify novel drug targets based on a deeper understanding into the spatiotemporal progression of disease and translate those discoveries into therapeutics that change the course of neurodegeneration. Cajal is now expanding to establish a world-class drug discovery organization.

The Scientist, Quantitative Lipidomics will assume responsibility for activities to develop and optimize quantitative assays in the area of translational biomarkers, with a focus on mass spectrometry quantitative assays for the detection of pharmacodynamic biomarkers in preclinical and clinical samples. In addition, as part of a larger effort to identify disease state- and disease progression-biomarkers, the candidate will explore the development and validation of other protein- or lipid- based assays for clinical interrogation. Working with preclinical and clinical colleagues, the candidate will work to refine and optimize biomarker strategies aimed at disease modification. The position also affords the opportunity to participate in and consult with all drug discovery and development projects that could benefit from assay development skills.

The position involves collaborating with multiple departments within Cajal and a larger team of external collaborators at contract research laboratories, and will report to the VP, Biomarkers.



  • Lead assay work to support brain disorder pharmacodynamic (PK/PD) studies in close collaboration with medicinal chemistry, neurobiology and pharmacokinetic experts.
  • Act as the biomarker lead for internal programs aimed at modulating lipid signaling in the brain, and lipid or protein-products due to dysregulated oxidative processes.
  • Lead and manage projects at CROs to enable PK/PD programs using mass spectrometry.
  • Establish internal capabilities at Cajal for the use of mass spectrometry in biomarker development, to support drug programs and novel screening platforms in human-based cellular systems.
  • Ideally, lead all protein-based discovery and mass spec-based quantification efforts in addition to lipid-quantitative assay detection.
  • Identify potential biomarkers responsive to changes in metal homeostasis using mass spectrometry methods.


This job might be great for you if you have:

  • A PhD and 5-10 years of preclinical and clinical assay development experience.
  • The candidate should have hands-on experience in lipidomics using mass spectrometry, including knowledge of shotgun lipidomics, liquid chromatography- high-resolution mass spectrometry, fragmentation techniques, and correlated data processing and analysis software. 
  • Knowledge of matrix-assisted laser desorption ionization-time of flight and imaging lipidomics is a plus.
  • Evidence of success in method development, qualification, validation using preclinical (rodent or primates) and clinical bio-samples, particularly CSF.
  • Expertise with clinical quantitative fluid biomarker studies for neurodegenerative indications (CSF and blood).
  • Expertise or familiarity in GLP, CLIA and regulatory aspects of clinical assay development.
  • Experience with establishing production and qualification of assay reagents (e.g., lipid and protein standards).
  • Demonstrable evidence of interpreting biomarker changes to underlying biology or disease processes.
  • Familiarity with industry standard quantitative biology tools, technologies, and vendors.
  • Demonstrable evidence of critical analysis and interpretation of data, writing technical reports, publications, IND supporting documents, and presentation to other teams and management.
  • A disposition to be very science- and data-driven, detail-oriented and thrive in a highly collaborative, team-oriented startup environment.
  • Excellent written and oral communication skills.
  • Demonstrated ability to evaluate, interpret, and present complex scientific data. 


Important Considerations

  • Cajal operates as a hybrid workplace, but we prefer that team members spend part of their time working on-site in our Seattle offices. Fully remote roles may be considered for exceptional candidates.
