Scientist, Assay Development (Contractor)

• Contribute directly to Recursions mission of revolutionizing drug discovery through our automation- and AI-powered platform.
• Develop optimize and validate cell-based and biochemical assays for deployment on our automated high-throughput screening platforms enabling the construction of Recursions Maps of Biology across diverse and often challenging human cell types.
• Execute assay workflows at scale monitoring performance against defined quality metrics and flagging deviations early.
• Analyze experimental data rigorously to validate processes troubleshoot systems and drive improvement sharing findings and collaborating with a cross-disciplinary team to refine approach and direction.
• Document methods results and protocols to a standard that allows workflows to be transferred and run reliably by others.
• Conduct impactful work in a matrixed environment where your insights and ideas are valued and expected.

You will join a cross-functional assay development team working to redefine preclinical drug discovery. The environment thrives on collaboration open communication and teamwork across multiple departments. You will work closely with biologists assay development associates data scientists software engineers automation engineers and our supply chain team. The teams key output is robust transferable assays for deployment on a high-throughput screening platform that integrates industry-leading automation to generate petabytes of high-dimensional data from human cells.

Strong communication skills are essential to our success as much of our coordination and reporting happens electronically. We value independent thought self-reflection and a growth mindset with a shared goal of continuous improvement. We also believe the best ideas come from diverse perspectives so if you have suggestions to improve the way we work we welcome them.

• B.S. Biology Biochemistry Cell Biology or a related field with 3 years of relevant industry or equivalent laboratory experience.
• Hands-on experience developing and optimizing cell-based or biochemical assays including mammalian cell culture and aseptic technique.
• Working knowledge of core molecular and cell biology techniques such as transfection nucleic acid and protein handling and plate-based readouts.
• Experience with automated computer-controlled laboratory instrumentation such as liquid handlers plate readers and imagers in 384 and 1536-well formats.
• Demonstrated ability to move experimental work forward independently and efficiently with general direction rather than step-by-step instruction.
• Demonstrated ability to adapt and quickly learn new techniques and instrumentation.
• Careful consistent documentation of protocols and results in an electronic lab notebook or equivalent.
• A passion for working in a fast-paced environment where youll apply creativity and independent thinking to assay development for early-stage drug discovery.

• Familiarity with assay qualification concepts and statistical quality metrics such as Z signal-to-background CV and dose-response fitting.
• Comfort with computational tools for data analysis in Python R or equivalent.
• Experience with genetic perturbation approaches such as CRISPR or RNAi or with omics readouts such as transcriptomics or proteomics.
• Experience working with primary or iPSC-derived cell models.

**This is a 9-month contractor role with working hours from 9:00am to 5:00pm Monday through Friday**

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 isnt about rushing but about moving the needle every day.
• We take ownership and accountability. Through ownership and accountability we enable trust and autonomyleaders 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.

Our values underpin the employee experience at Recursion. They are the character and personality of the company demonstrated through how we communicate support one another spend our time make decisions and celebrate collectively.
