Principal Clinical Scientist

About The Role

What if your career-long expertise in clinical trial design and regulatory science could directly shape how AI reasons about medical evidence — influencing the systems that will define the future of biomedical research?

We're looking for a Principal Clinical Scientist to bring senior-level clinical rigor into the development of cutting-edge AI models. You'll work alongside world-leading AI research teams to ensure the clinical data, analyses, and reasoning embedded in frontier AI systems meet the standards expected in real-world regulatory submissions.

This is a fully remote, flexible contract role built for experienced clinical scientists who want to do meaningful work on their own terms.

• Organization: Alignerr
• Type: Hourly Contract
• Location: Remote
• Commitment: 10–40 hours/week

• Design and critically review clinical trial protocols used to generate high-quality, regulator-ready datasets for AI training and evaluation
• Interpret and audit clinical trial results to ensure accuracy, internal consistency, and alignment with regulatory standards
• Evaluate AI-generated clinical analyses for scientific soundness, methodological integrity, and regulatory relevance
• Provide expert, structured feedback that directly improves how AI models reason about clinical trial data, endpoints, and outcomes
• Help establish the bar for what rigorous, trustworthy clinical AI looks like in practice

• Senior-level clinical scientist with hands-on experience designing trial protocols for regulatory submission (FDA, EMA, or equivalent)
• Deep expertise interpreting clinical data and navigating the expectations of major regulatory agencies
• Strong grounding in clinical research methodology, biostatistics, translational science, or a related discipline
• Meticulous and structured in how you evaluate evidence — you notice when something doesn't hold up
• Able to communicate complex scientific judgments clearly and concisely in written form
• Comfortable working independently and asynchronously in a remote environment

• Prior experience with data annotation, data quality frameworks, or AI evaluation workflows
• Background in pharmacovigilance, outcomes research, or health technology assessment
• Familiarity with AI tools or clinical informatics platforms

• Work directly on frontier AI systems that are reshaping how clinical and biomedical research is understood and conducted
• Influence how AI evaluates, interprets, and communicates real-world clinical evidence at scale
• Fully remote and flexible — work when and where it suits you, with no fixed schedule
• Freelance autonomy with meaningful, intellectually rigorous work on every project
• Collaborate with leading AI research labs and clinical experts from around the world
• Potential for ongoing work and contract extension as new projects launch
