- 6 certified filings for “Senior Scientist” (Biochemists and Biophysicists) in MA: $100k–$122k, median $101k. Most were filed at wage level I (50%) — 1 lottery entry, ≈15% projected selection odds for cap-subject employers. Source: US Department of Labor LCA disclosure data (Oct 2025 – Jun 2026).
US H-1B: cap-subject employers enter a lottery weighted by wage level — Level I gets 1 entry, Level IV gets 4 (DHS projected selection odds ≈15% at Level I to ≈61% at Level IV). Universities and non-profit research employers are cap-exempt. The $100,000 fee for new petitions from abroad is currently blocked by a court order (appeal pending).

• Ensure high scientific standards in conducting and reporting of nonclinical safety and investigative toxicology studies.
• Provide scientific leadership within Preclinical Safety, particularly with experience in the conduct and interpretation of reproductive and developmental toxicity studies and data (preferred).
• Provide internal expertise for global nonclinical safety issues on various expert groups or internal committees as required.
• Prepare scientific publications and presentations from toxicology and safety pharmacology studies as appropriate.
