Find engineers and operators at companies in Sydney

Sydney is one of the densest markets for technology talent in the world. The list above ranks the largest companies headquartered in Sydney by current headcount, drawn from public LinkedIn and Crunchbase records. With 2,600 matching companies in Refolk’s index, the depth of engineers, designers, product managers, and founders is broad across stages and industries.

Hiring in Sydney usually means hiring out of these companies. The biggest names anchor the talent pool - every senior engineer in Sydney likely has at least one of them on their resume - and the fast-growing ones generate the most movement.

Refolk lets you reach into this pool with plain English. Ask for “senior backend engineers in Sydney who’ve shipped at scale” or “founders in Sydney who left in the last year” and Refolk returns a ranked shortlist with the evidence behind each match.

How this list is built

Refolk pulled the largest companies headquartered in Sydney from public LinkedIn and Crunchbase records, ranked them by current employee count, and kept those with at least 25 employees. The list refreshes once a day.
