H-1B sponsorship profile: Gritstone Bio. Across U.S. Department of Labor LCA disclosures, Gritstone Bio filed 4 Labor Condition Applications covering 4 H-1B worker positions between fiscal year 2023 and fiscal year 2023. The employer’s DOL certification rate sits at 100% (4 certified of 4 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 Gritstone Bio’s H-1B petitions range from $132,000 at the low end to $220,000 at the high end, with a petition-weighted average of $155,500. That range reflects the mix of occupations the company sponsors, led by Bioinformatics Engineer II (2 petitions at $135,000 avg), followed by Scientist I, Vaccine Technology and Director, Clinical Data Management. 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.
