Senior Scientist, Immunology in London

Your work will change lives. Including your own.

The Impact You’ll Make

We are seeking an innovative Senior Scientist to join our Experimental Immunology team. In this primarily lab-based role, you will provide critical cellular data to support therapeutic projects, often venturing into areas of novel biology. You will work closely with the Recursion Discovery team to uncover solutions for a variety of target classes and I&I indications. You will have the freedom to design, plan, and execute complex experiments. You will drive projects from target ideation and validation through to adoption into the portfolio, with opportunities to take on project leadership roles. Working in our newly built laboratories with access to state-of-the-art assay technologies (FRET, Luminescence, FACS, High‑Content Imaging) and advanced automation you will be encouraged to evaluate and deploy the latest scientific developments to create efficient processes. You will develop translationally relevant screening assays and function as a core immunology expert within project teams. This role offers substantial scope for continuous learning, with exposure to all stages and disciplines of the drug discovery process. You will also have the opportunity to present your findings both internally and externally.

In this role, you will:

• Design and execute complex in vitro assays using primary human immune cells and patient-derived tissues for use in target validation, mechanism of action studies and small molecule screening.
• Drive projects through the entire development lifecycle, from initial target ideation and validation to formal adoption into the company portfolio.
• Deploy state-of-the-art technologies such as flow cytometry and high‑content imaging to address key scientific questions.
• Lead scientific initiatives and early drug discovery programs by evaluating the latest scientific developments and managing external collaborations to generate critical model data.
• Provide immunology expertise to guide in vitro and in vivo workstreams in cross‑functional matrix project teams.

The Team You’ll Join

You will be joining an established immunology group consisting of several experienced immunologists. The experimental immunology team work on a wide range of projects spanning target ideation through to advanced preclinical programs. You will lead project strategy and execution within a small group of project leaders, and collaborate extensively with data scientists, chemists, and biologists throughout the organization and externally, to advance milestones and provide insights to further advance Recursion’s capabilities.

The Experience You’ll Need

• Ph.D. in Immunology or a related discipline or a BSc/MSc degree with significant relevant experience, preferably in the pharmaceutical or biotechnology industry.
• Extensive hands‑on experience in designing, executing and optimizing in vitro assays utilizing primary human immune cells/patient‑derived tissue.
• In‑depth understanding of gut inflammation and knowledge of in vitro relevant translational and in vivo models.
• Experience of screening small molecules and working on a drug discovery program and in‑depth knowledge of data analysis including dose‑response relationships.
• Exposure to a wide range of assay technologies such as ELISA, FRET, RT‑PCR, flow cytometry and imaging with experience in target validation studies.
• Excellent interpersonal and communication skills, both written and verbal, with ability to communicate technical information to a non‑specialist audience while working across multiple projects.

Working Location & Compensation:

This is a laboratory‑based role in our Oxford office. 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 £70,400 to £93,500. 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.
