Find engineers at top Series D companies

Series D companies are some of the most active hirers in the market. The list above ranks the largest Series D-stage companies by current headcount, drawn from public LinkedIn and Crunchbase records. Across 1,448 matching companies, you’ll find senior engineers, founding designers, product leads, and operators worth tracking.

Companies at this stage tend to share a profile: clear product-market fit, fresh capital, and aggressive hiring plans. That makes the people already there valuable signals - early hires usually become the next hiring managers, founders, and angel investors.

Refolk lets you reach into this pool with plain English. Ask for “Series D fintech founders hiring senior engineers” or “design leads at Series D companies” and Refolk returns a fresh ranked shortlist with the sources behind each match.

How this list is built
