Recursion Pharmaceuticals

Data Science
Toronto, ON, Canada
Posted on Friday, June 28, 2024

Please Note: Our offices are closed for our annual Summer Break from Monday, July 1, 2024 through Friday, July 5, 2024. Our response to your application will be delayed.

Your work will change lives. Including your own.

The Impact You’ll Make

With treatments for hundreds of diseases in our sights, we’ve built a data science team with domain expertise in computer science, bioinformatics, physics, biology, mathematics, applied statistics, and more. We work side-by-side with biologists, automation scientists, chemists, software engineers, and many others; together, we develop the tools and methods to turn our experimental data into treatments for pathologies that affect the lives of countless individuals. As a data scientist with a digital chemistry focus, you will design and build chemistry analysis, models and workflows. In addition, you will be a part of a multidisciplinary team that will support you in advancing your projects from idea to a deployed solution that will help Recursion advance drug candidates. In this role, you will:

  • Partner with chemists and biologists to understand their processes and the questions that they are asking at each stage of the drug discovery funnel
  • Develop methods, metrics, benchmarks, and models to help drive drug discovery in a standardized way
  • Convert exploratory analysis into production-quality functions that can be incorporated into in-house Python packages and that support at-scale generation of data packages to accelerate decisions on passing programs through internal stage gates
  • Create and analyze enormous sets of connected data for a variety of programs to learn how best to advance drug discovery in an industrialized way
  • Collaborate with engineering teams to mature your models and analyses and put them into productionized workflows
  • Deliver quickly and iteratively, both supporting ad-hoc requests and building improvements for the long-term in agile workstreams
  • Learn to leverage new code packages and data science techniques as needed


Making Toronto, Canada your home base is ideal, however, we will consider on-site work in our Salt Lake City, Utah office as well

| Expected to be on-site 50% of the time.

The Team You’ll Join

Our purpose is to build, test, support, and improve the Machine Learning (ML) models that drive RecursionOS. Our scope of work is vast, including the development of benchmarks, the refinement of our models and maps, and supporting their widespread adoption across the organization.

Our goal is to foster continuous, hypothesis-driven improvements inspired by experimental outcomes. This will be achieved by establishing robust ML operational practices that accelerate model development, testing, and deployment. We will work with all Recursion scientists to develop a clear understanding of our models, uncover new biology & chemistry, make meaningful predictions, and profile the applicability of our methods. Identifying performance gaps and model limitations will inspire new benchmarks, data sources, representations, model architectures, and training strategies.

The Experience You’ll Need

  • 3-5+ years practical experience applying probability, statistics, and machine learning to real-world datasets in service of academic or business applications and recommendations
  • 2+ years of experience in the field of digital chemistry (particularly medicinal chemistry)
  • Experience participating in projects that routinely call for cross-disciplinary collaboration, involving the communication of complex theories and techniques to audiences with a range of technical background
  • High fluency with the Python data science stack and chemistry specific libraries
  • Experience in creating compelling visualizations of high-dimensional data that enable clear decision-making and interpretation
  • Experience in collaborative software development and peer code review, including version control tools like git
  • Experience working within a fast-paced interdisciplinary team to solve business-relevant problems
  • Nice to have: experience training deep learning models with ML libraries like pytorch, tensorflow, etc.Nice to have: experience developing, releasing, and maintaining data products in a continuous-use production environment

How You’ll be Supported

  • You will be assigned a peer trail guide to support you as you onboard and get familiar with Recursion systems
  • Regular 1:1s with supervisor provides opportunities for support and feedback
  • Receive real-time feedback on code quality and best practices from a team of peers
  • Ability to participate and learn from your colleagues in our regular all-hands, journal club & tech talks for Data Science
  • Option to publish research and/or attend conferences to learn more from colleagues, networks, and more to better your skillset.


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:

  • Developing: $187,000 CAD

You will also be eligible for bonuses and equity compensation + our comprehensive benefits package for United States based candidates. The range displayed on each job posting reflects target ranges for US new hire salaries and is determined by job, level, and market factors.

During the interview selection process, you will connect with a Talent Acquisition Partner who will be your advocate and ally to ensure you receive the appropriate compensation that meets your needs for your skills, experience, and relevant education/training, while also reviewing our very competitive total rewards package.

The Values That We Hope You Share:

  • We Care: We care about our drug candidates, our Recursionauts, their families, each other, our communities, the patients we aim to serve and their loved ones. We also care about our work.
  • We Learn: Learning from the diverse perspectives of our fellow Recursionauts, and from failure, is an essential part of how we make progress.
  • We Deliver: We are unapologetic that our expectations for delivery are extraordinarily high. There is urgency to our existence: we sprint at maximum engagement, making time and space to recover.
  • Act Boldly with Integrity: No company changes the world or reinvents an industry without being bold. It must be balanced; not by timidity, but by doing the right thing even when no one is looking.
  • We are One Recursion: We operate with a 'company first, team second' mentality. Our success comes from working as one interdisciplinary team.

Recursion spends time and energy connecting every aspect of work to these values. They aren’t static, but regularly discussed and questioned because we make decisions rooted in those values in our day-to-day work. You can read more about our values and how we live them every day here.
