Earli tackles the #1 problem in the $100B cancer drug market: systemic toxicity. On-target/off-tumor effects force suboptimal dosing, reduced efficacy and sidelining some of the most potent drug classes such as cytokines. Earli’s BioAI approach flips this paradigm: Drugs are producedonly where needed—in the tumor,by the tumor,against the tumor. Cancer cells become their own drug factories, enabling localized immune activation, even in cold tumors.

This was enabled by three core innovations:

Extrahepatic lipid nanoparticles (LNPs) that reach tumors such as lung cancer
AI-designed genetic switches that activate only in malignant cells by sensing transcription factor dysregulation
Local production of immune therapies (TCEs, cytokines, multispecifics) at the tumor site — “produce locally, consume locally”

Together, these technologies create a new biological control layer, allowing tumors to self-identify and trigger their own targeted immune attack—achieving specificity beyond current targeted or IO therapies.

Earli plans to enter the clinic by mid-2027 with a Phase 1/2 lung cancer trial. The company is backed by a16z, Khosla, Perceptive, Alex Gorsky, Marc Benioff, Breyer, Emerson Collective, Sands Capital and others. The SAB includes Jim Allison (Nobel Laureate, MD Anderson), Bob Langer (Co-founder Moderna, MIT), Phil Greenberg (Co-founder Juno), Amy Abernethy (frm. Principal Deputy FDA Commissioner), Bill Hait (former J&J EVP Oncology R&D), and Alan Ashworth (President UCSF Cancer Center). The leadership team brings deep gene therapy, LNP, CMC and tech experience; CEOCyriac Roeding previously led a $250M (11x return) exit.

Oversee and manage the In vivo/Translational Biology group at Earli to support the growth and expansion of the team
Develop preclinical strategy for advancing Earli’s candidate pipeline in immuno-oncology, including selection of appropriate in vivo models, efficacy, safety, PK/PD characterization, and development of translational biomarkers to support FIH clinical studies
Help lead operational planning and oversight of internal and external in vivo studies
Be the key stakeholder to select and oversee CROs to conduct external non-GLP and GLP safety and toxicology studies
Help author nonclinical sections of regulatory filings, including the production of high-quality technical reports including statistical analyses and data integrity review for these filings
Proactively foster the growth of team members and identify opportunities for staff to develop into top-tier, independent pharmacology team members
Present key findings at internal and external meetings

Education Requirements

Ph.D. in Pharmacology, Pharmaceutical Sciences, Toxicology or related discipline
DABT preferred, but not required
Candidates with a Pharm.D. or M.S. and 8 or more years leading nonclinical safety programs will be considered, especially with a background in the development of nucleic acid-based drugs

Required Experience, Knowledge and Skills

Required Experience, Knowledge, and Skills
Proven track record leading nonclinical safety, pharmacology, and biomarker strategies to support development of nucleic acid therapeutics through IND filing and beyond
A deep understanding of the design of safety and efficacy studies of viral or non-viral genetic medicines (mRNA-LNPs or DNA-LNPs preferred) using systemic, repeat administration. Proven translation of programs from Discovery into human clinical studies is highly desired.
Strong and documented first-hand experience in leveraging state-of-the-art immuno-oncology preclinical models, especially humanized models and orthotopic/metastatic as well as GEMM/transgenic cancer models for use in therapeutics development
Proven ability to oversee the development and validation of new models. Experience working with atypical and larger preclinical cancer models (e.g. dogs) is a plus.
Successful demonstration of ability to rigorously analyze and interpret diverse, multidisciplinary data sets.
Significant experience working with CROs to design and execute external studies.
Significant experience in writing regulatory documentation to support IND filings.
Previous experience in managing small to medium sized groups is required
Excellent verbal communication and interpersonal skills are required
As a key member that directly influences strategy, you must be able to think independently, effectively communicate and fully integrate into a high achieving team
