ALTEROME THERAPEUTICS Principal Investigator / Associate Director, In Vivo Pharmacology and Biology San Diego, CA | Full-Time | Reports to SVP, Biology Every alteration tells a story — a mutation that opens a door to a treatment that didn't exist before. At Alterome, we're writing the next chapter of that story for cancer patients who've run out of options. If you want your in vivo pharmacology work to move a KRAS-driven pipeline from bench to clinic, this is the seat.

Who We Are

Alterome is a clinical-stage biotech advancing best-in-class and first-in-class treatments for patients where options were previously limited. We're built on co-elevation — diverse expertise, one mission — and we operate by accountability, creativity, perseverance, longevity, and compassion. Small team, high trust, real stakes.

The Role You'll lead the design, execution, and interpretation of the preclinical oncology studies that prove our science works — efficacy and PK/PD studies, dose and regimen strategy, and the tumor models (PDX, CDX, syngeneic, and beyond) that make our translational story credible. You'll own CRO partnerships end to end, turn data into go/no-go recommendations program leadership can act on, and help build the in vivo infrastructure that scales with our pipeline. This role flexes to Principal Investigator or Associate Director based on what you bring.

What You'Ll Do

Design and direct in vivo efficacy and PK/PD studies — from dose selection through data interpretation. Own CRO relationships: protocol review, study monitoring, troubleshooting, and data quality. Partner with DMPK, translational, and clinical teams to turn model data into program strategy.

Evaluate and onboard new PDX, CDX, and other translationally relevant tumor models. Integrate biomarker and translational endpoints into study design. Present findings directly to program and executive leadership — your data drives real decisions.

Build the data systems and standardized workflows that make in vivo pharmacology scale. Mentor junior scientists as the team grows. What You Bring Ph D.

in Pharmacology, Cancer Biology, or related field + 5 years in vivo pharmacology in biotech/pharma (or MS + 8 years, or BS + 10 years). A track record of designing and executing in vivo efficacy and PK/PD studies, ideally in oncology or immuno-oncology. Direct experience managing outsourced studies at CROs and working with PDX/CDX models.

Comfort translating complex data into clear, decision-ready recommendations. Excellent communication and presentation skills — you can hold a room of scientists and executives alike. We are especially interested in you if you have recent experience working with KRAS-driven cancers and/or MAPK signaling pathway biology.

Why Alterome You'll work on a KRAS program at a company small enough that your studies directly shape clinical strategy — not lost in a portfolio of forty programs. You'll have real latitude to build the in vivo function the way it should be built, and a direct line to the people making pipeline decisions. Ready to help write the next chapter?
