Job Description

Your work will change lives. Including your own.

The Impact You’ll Make

Recursion is at the forefront of reimagining drug discovery through the integration of automated cell biology, high-dimensional and diverse data sets, and sophisticated analytics and machine learning. We are seeking an in vitro toxicologist who can drive a collaborative effort aimed at identifying and validating novel in vitro safety assessments across our diverse portfolio of drug projects. Currently, our high-throughput platform teams utilize technologies such as brightfield cell imaging and phenomics, high-throughput transcriptomics and fast-proteomics coupled with our advanced machine learning analytics to mine the data for novel relationships and to help decode biology. We see broad opportunities to expand the platform for decoding toxicity/safety and we are seeking for someone with the passion to drive this effort. The goal is to build novel, advanced in vitro toxicology screening to the Recursion platform that to predict toxicities such as cytotoxicity, hepatotoxicity, or cardiotoxicity.

Career development opportunities will include the opportunity to work with the early project teams to provide scientific expertise and leadership for the safety assessment of Recursion programs from early discovery through to candidate selection and beyond. You will contribute to the assessment and selection of novel drug targets and the optimisation of novel candidate molecules using innovative molecular and cellular technologies to enhance the safety profile of our drug candidates.

In this role, you will

• Implement innovative experimental or computational strategies using multi-dimensional data to assess and/or provide mechanistic understanding of safety issues.
• Adapt and apply toxicology screening strategies to predict, assess and mitigate on-target, off-target and other drug-related safety risks in support of the drug discovery portfolio.
• Provide subject matter expertise on cross-functional project teams within the discovery organization with an opportunity to oversee the preclinical safety strategy in development as projects progress.
• Act as a key resource for early safety assessment during the discovery phase, providing scientific knowledge and expertise to cross-functional project teams on the appropriate interpretation of in vitro data.
• Collaborate with external collaborators to ensure best practice for in vitro safety assessment.
• Partner with the project teams to develop optimal strategies to address specific safety issues within project teams. Provide verbal and written summaries for internal discussions. Present summary data to project teams, senior leadership and external partners as needed.

The Team You’ll Join

Reporting to the Vice President of Toxicology you’ll be joining a dynamic toxicology team that works across the portfolio to guide projects through the various stages of discovery and development. This high performing team will work together to continually improve our workflows to drive towards greater efficiency and automation.

The Experience You’ll Need

• Pharm D or Ph.D in toxicology, Pathology, Physiology, Biochemistry or expertise in related biological scientific disciplines with preferably 1 or 2 years of postdoctoral experience.
• Background in cell biology and imaging techniques, or molecular biology running transcriptomic or proteomic experiments with experience in designing and developing high throughput screening assays.
• Proven ability to troubleshoot technical issues with biological experiments.
• Skilled in interpreting observed phenotypic signatures to potential mechanisms of toxicity.
• Highly motivated scientist with the ability to work independently as well as collaborate with stakeholders to drive the development of novel toxicology assays.
• Stay informed on the latest trends and advancements in advanced in vitro platforms and physiological models, and their potential applications in improving the predictive power of toxicology studies.
• Keen interest in artificial intelligence and its application to drug discovery. Experience with the use of AI-tools to predict toxicology endpoints.

Working Location & Compensation:

This position is based at our office located in Salt Lake City . Please note that we are a hybrid environment and ask that employees spend 50% of their time in the office. Relocation support can be provided for this role.
