Principal Research Scientist - Cancer Biology

Beacon Hill
South San Francisco, CA

Position Overview

We are looking for a highly motivated PhD-level scientist with strong laboratory expertise to contribute to a priority research initiative focused on understanding cancer biology mechanisms through advanced cellular and molecular approaches. This role demands technical depth, critical thinking, and a hands-on approach to experimental science.

The individual in this position will collaborate with a cross-functional team to investigate the biology of a novel target and support small-molecule drug discovery efforts. This is a strong opportunity to play a key role in early-stage scientific discovery within oncology. Title and level will be determined based on experience.


Key Responsibilities

  • Design, execute, and troubleshoot in vitro experiments to evaluate target biology, pathway activity, and drug mechanism of action
  • Conduct cell-based assays incorporating gene knockdown/knockout (siRNA, shRNA, CRISPR), overexpression systems, and pharmacologic modulation
  • Utilize a range of molecular and cellular biology techniques to study signaling pathways, protein trafficking, immune-related responses, and genetic interactions
  • Analyze and interpret experimental data with a focus on accuracy, reproducibility, and mechanistic understanding
  • Collaborate closely with project teams to ensure experimental strategies align with broader research and therapeutic goals
  • Present data and insights effectively in team settings and contribute to ongoing program direction and planning


Qualifications

  • PhD in cancer biology, molecular biology, cell biology, or a related scientific discipline
  • Postdoctoral training or 4–8 years of industry experience is preferred
  • Proven ability to independently design and carry out hypothesis-driven research
  • Strong background in mammalian cell culture, viability/proliferation assays, and flow cytometry
  • Hands-on experience with techniques such as qRT-PCR, RNA isolation, Western blotting, ELISA, HTRF, MSD, and confocal microscopy
  • Experience with functional genomics approaches and assay development for studying protein function, degradation, trafficking, or immune signaling is highly valued
  • Strong analytical skills with the ability to integrate data from multiple experimental platforms
  • Familiarity with data analysis and visualization tools is a plus
  • Experience working with external partners or CROs is beneficial


Ideal Profile

  • Demonstrates scientific curiosity paired with a results-oriented mindset
  • Thrives in a fast-paced, early-stage research environment
  • Adaptable and comfortable navigating evolving scientific challenges
  • Effective communicator who collaborates well across teams and contributes to a positive, accountable, and high-performance culture
