Executive Director, Toxicology

Your work will change lives. Including your own.

The Impact You'll Make

As the Head of Toxicology, you will sit at the crucial intersection of Discovery and Development, supporting both our internal pipeline and strategic partnerships. You will lead a team responsible for embedding modern, data‑driven decision‑making into our NCE progression, ultimately accelerating our mission to decode biology to radically improve lives.

As a forward‑looking leader, you will be instrumental in positioning Recursion at the forefront of the industry’s shift away from reliance on traditional pre‑clinical studies. You will champion the adoption and validation of highly predictive human models, as this is central to our TechBio approach of industrializing drug discovery.

In this role, you will:

• Guide internal strategy and external collaborations to ensure Recursion’s toxicology and safety science remains state‑of‑the‑art, driven by the mantra to "predict more, test less."
• Provide pivotal support to Discovery teams, expertly guiding them through exploratory small molecule safety studies toward Development Candidate (DC) nomination.
• Support Development teams in successfully navigating regulatory (GLP / IND‑enabling) small molecule studies through First‑in‑Human (FIH) trials and beyond.
• Partner with data science, AI, and machine learning experts to design, deploy, and leverage the state‑of‑the‑art computational and predictive tools that generate robust, clinically‑relevant translational datasets within the Recursion OS.

The Team You Will Join

You will lead the Toxicology function and operate in a highly cross‑functional manner, collaborating closely with leaders across Discovery, Clinical Development, Translational Biology, and our core AI/ML and Data Science organizations across our various locations.

The Experience You’ll Need

• Ph.D. is strongly preferred together with accreditation such as ERT or DABT.
• As an experienced leader, you will have worked at / with a mixture of company types (CRO, large pharma, and biotech).
• You are an integrator of information, skilled at synthesizing complex data to provide Project Teams, Partners, and Management with data‑driven recommendations and risk assessments as projects advance through the portfolio.
• Demonstrated ability to lead interdisciplinary, cross‑functional teams in a complex organization. Must be able to manage and prioritize multiple projects to ensure they are high‑quality, on time, and on budget.
• Proven track record of supporting programs from preclinical discovery into clinical development, specifically supporting research for small molecule drugs.
• Strong working knowledge of preclinical drug discovery models and the ability to synthesize scientific content and strategy for senior management. Must be able to manage complex variables and uncertainty to align drug development with preclinical research.
• Excellent communication, presentation, and high‑level negotiation skills. Ability to resolve conflict and effectively interact with diverse stakeholders, including discovery, clinical, regulatory, and operations teams.
• Exceptional attention to detail, with strong planning, time management, and organizational skills.

Working Location & Compensation:

This is an office‑based, hybrid position at one of our offices located in Salt Lake City, Utah / London / New York City . Employees are expected to work in the office at least 50% of the time.

At Recursion, we believe that every employee should be compensated fairly. Based on the skill and level of experience required for this role, the estimated current annual base range for this role is $255,200 to $331,100 (USD) . You will also be eligible for an annual bonus and equity compensation, as well as a comprehensive benefits package.

The Values We Hope You Share:

• We act boldly with integrity. We are unconstrained in our thinking, take calculated risks, and push boundaries, but never at the expense of ethics, science, or trust.
• We care deeply and engage directly. Caring means holding a deep sense of responsibility and respect – showing up, speaking honestly, and taking action.
• We learn actively and adapt rapidly. Progress comes from doing. We experiment, test, and refine, embracing iteration over perfection.
• We move with urgency because patients are waiting. Speed isn’t about rushing but about moving the needle every day.
• We take ownership and accountability. Through ownership and accountability, we enable trust and autonomy – leaders take accountability for decisive action, and teams own outcomes together.
• We are One Recursion. True cross‑functional collaboration is about trust, clarity, humility, and impact. Through sharing, we can be greater than the sum of our individual capabilities.
