Chemistry Expert (Masters/PhDs)
up to $90/hr
About this role, in Alignerr's words
What if your years of chemistry expertise could directly shape how AI reasons through the most complex scientific problems in the world? We're looking for Masters and PhD-level chemists to design, solve, and evaluate advanced chemistry problems that train the next generation of AI models — making them sharper, more rigorous, and genuinely scientifically literate.
What you'll do
- Design and solve complex, real-world chemistry problems spanning organic, inorganic, physical, or computational chemistry
- Review and evaluate AI-generated chemistry content for scientific accuracy, depth, and rigor
- Craft challenging problem statements that push the boundaries of AI reasoning in the sciences
Show all 5 itemsHide the other 2 in What you'll do
- Collaborate asynchronously with AI researchers and fellow domain experts to refine model outputs
- Ensure all deliverables meet a high standard of scientific clarity and correctness
Candidate background
Who You Are
- Hold a Master's or PhD in Chemistry or a closely related field
- Deep expertise in at least one core area: organic, inorganic, physical, or computational chemistry
- Comfortable working with Python or computational chemistry tools (e.g., Gaussian, VASP)
- Exceptional written communicator — you can explain complex science clearly and precisely
- Self-motivated and reliable when working independently in an asynchronous environment
- Fluent in English
