Working within a collaborative, cross‑functional environment, this individual will play a key role in shaping and advancing a pioneering cancer biology research program. Location: SSF Pay: $70 - 85/hr. DOE Key Responsibilities Independently design, execute, analyze, and troubleshoot complex in vitro studies to investigate target biology, pathway regulation, and drug mechanisms of action. Develop and apply cellular models utilizing gene perturbation technologies, including CRISPR, siRNA/shRNA, overexpression systems, and pharmacologic interventions. Utilize a broad range of molecular and cellular biology techniques to explore oncogenic signaling pathways, protein function, cellular trafficking, immune-relevant phenotypes, and synthetic lethal interactions. Design and optimize mechanistic assays to interrogate target function and therapeutic response. Generate high-quality, reproducible datasets and apply rigorous quantitative analysis to derive mechanistic insights. Integrate data across multiple experimental platforms to develop and test biological hypotheses. Maintain meticulous experimental records and ensure adherence to high scientific standards. Partner closely with project teams to align experimental strategies with translational and therapeutic objectives. Present research findings and recommendations to multidisciplinary teams and senior leadership. Contribute scientific expertise to program strategy and help guide the evolution of research priorities. Collaborate effectively with external partners, CROs, and scientific collaborators as needed. Qualifications PhD in Cancer Biology, Molecular Biology, Cell Biology, Genetics, or a related discipline. 4+ years of industry experience. Deep understanding of tumor biology, including cancer genomics, oncogenic signaling, cancer cell biology, synthetic lethality, and therapeutic vulnerabilities. Proven track record of independently driving hypothesis‑based research programs with minimal supervision. Strong expertise in molecular biology, cellular biology, biochemistry, and quantitative experimental design. Extensive hands‑on experience with mammalian cell culture, cell viability and proliferation assays, and multiparametric flow cytometry. Proficiency with gene expression analysis (qRT‑PCR, RNA isolation/preparation), protein characterization techniques (Western blot, ELISA, HTRF, MSD), confocal microscopy, and functional genomics approaches. Demonstrated ability to interpret complex datasets, synthesize findings, and communicate scientific conclusions effectively. Preferred Experience developing mechanistic assays focused on protein function, degradation, trafficking, or immune signaling pathways. Familiarity with computational tools for biological data analysis, visualization, and interpretation. Experience managing or collaborating with CROs and external research partners. Desired Attributes Passion for scientific discovery coupled with a pragmatic, results‑oriented mindset. Intellectual curiosity and commitment to rigorous, data‑driven decision‑making. Thrives in a fast‑paced, discovery‑stage research environment. Adaptable and resilient when navigating scientific uncertainty and evolving priorities. Strong interpersonal and communication skills, with the ability to influence and collaborate across functions. Commitment to fostering a culture of accountability, inclusion, innovation, and scientific excellence.
