About this role

Primary Responsibilities

- Design and execute in vivo studies that de-risk novel targets, using genetic knockdown/overexpression and tool molecules to test target–phenotype links

- Outsource or internally establish rodent cardiac disease models, including transgenic lines and surgical models such as TAC and MI

- Run therapeutic screening studies that rank candidates on efficacy, dose-response, durability, and identify hit molecules for advancement

- Dose by multiple routes (IV, IP, SC, IM, PO, retro-orbital) and by osmotic minipump across longitudinal studies

- Lead study takedowns: necropsy, blood and tissue collection, and processing for histology, molecular, and ex vivo endpoints, including Langendorff cardiac dissociation

- Partner with Translational Sciences to establish bioanalytical methods for biodistribution and target engagement in rodent tissues, and align on models with clinical endpoints/biomarkers

- Analyze, interpret, and present data to project teams; keep study records in the ELN in line with IACUC and animal welfare standards

- Manage study logistics, manage budgets, flag capacity or timeline risks early, and ideate novel methods for pharmacology and physiology

Required Skills and Qualifications

- PhD in physiology, pharmacology, cardiovascular biology, or a related field with 0–3 years of postdoctoral or industry experience; or MS with 5+ years of industry experience

- Hands-on rodent experience: handling, multi-route dosing, blood collection, survival surgery, and necropsy

- Track record using rodent disease models for target validation or efficacy testing of molecules

- Proven understanding of power analyses, methods of randomizing animal models and appropriate uses of statistical methods

- Strong data analysis skills (e.g., GraphPad) and clear written and verbal communication

- Organized and independent; able to run several longitudinal studies at once within a collaborative team

- Ability to regularly work onsite at HQ in New York City

Preferred Skills and Qualifications

- Industry experience in a small, fast-paced biotech is highly preferred

- Working knowledge of qPCR/ddPCR for vector/mRNA, ELISA/LC-MS for ASO, RNAscope/IHC for tissue localization, WB/ ELISA/MSD for protein detection

- Hands-on echocardiography in mice and rats (e.g., Vevo)

- ECG and blood pressure telemetry implantation and analysis in mice and rats (e.g., Ponemah)

- Cardiac surgical models (TAC, MI) and invasive hemodynamics (PV-loop)

- Demonstrated experience with models of neurodegenerative disease, particularly ataxia or cerebellar disorders, including execution and interpretation of rotarod, gait analysis, balance beam, grip strength, and longitudinal behavioral studies

- In vivo experience working with and advancing AAV or oligonucleotide therapeutics

- Experience selecting and evaluating CROs to perform animal studies

- AALAS certification or equivalent

Compensation is dependent on qualifications and experience
