H-1B sponsorship profile: Mammoth Biosciences Inc. Across U.S. Department of Labor LCA disclosures, Mammoth Biosciences Inc filed 14 Labor Condition Applications covering 14 H-1B worker positions between fiscal year 2023 and fiscal year 2025. The employer’s DOL certification rate sits at 100% (14 certified of 14 filed), a useful proxy for how cleanly their prevailing-wage attestations pass the Labor Department’s preliminary review before USCIS adjudication.

Compensation spread. Offered wages on Mammoth Biosciences Inc’s H-1B petitions range from $77,000 at the low end to $154,500 at the high end, with a petition-weighted average of $123,307. That range reflects the mix of occupations the company sponsors, led by Senior Scientist I (2 petitions at $117,500 avg), followed by Senior Project Manager and Scientist I. H-1B salaries reported on LCAs must meet or exceed the DOL prevailing wage for the role and worksite, so the spread also tracks wage-level geography and seniority.
