Staff Materials Research Scientist, PFAS Alternative Discovery
$163K–$306K
United States · Remote · Staff · Full-time · Posted Jul 24, 2026
- Experience
- 6+ years of post-PhD experience (or equivalent) in industrial or applied R&D developing, formulating, or qualifying semiconductor process chemicals, including hands-on experience with PFAS-lean/PFAS-free alternatives.
- Education
- PhD in Chemistry, Chemical Engineering, Materials Science, or a related field.
About the job
Leads partner-facing validation and candidate ranking for AI-driven discovery of PFAS-lean or PFAS-free semiconductor materials, translating manufacturing requirements and experimental feedback into improved discovery cycles.
What you'll do
- Lead partner engagements to define target specifications, constraints, and qualification criteria; translate validation results into actionable improvements.
- Run the generative chemistry workflow, assess and rank compounds, and validate candidates against semiconductor process, performance, and EHS requirements.
- Coordinate with internal data, computational chemistry, machine-learning, and generative-modeling teams to align targets and screening objectives.
What they ask for
- PhD in Chemistry, Chemical Engineering, Materials Science, or a related field, with deep specialization in semiconductor process materials and/or fluorochemistry.
- Working knowledge of semiconductor unit processes and process-material qualification requirements.
- Demonstrated ability to lead external industrial partner engagements and translate experimental results into computational or modeling requirements.
- Proficiency in Python and familiarity with generative molecular design, high-throughput virtual screening, or ML property prediction.
Nice to have
- Hands-on experience with PFAS phase-out or fluorine-free reformulation in a fab or specialty-chemicals setting.
- Experience defining qualification protocols or reliability criteria with fabs, OEMs, or chemical suppliers; publications or patents in relevant fields are also valued.
