### About the company

Kadmos is on an ambitious mission to revolutionise salary payments to migrant workers. The Berlin-based startup was founded in 2021 by MIT graduates Justus Schmueser and Sasha Makarovych to bring fintech, low margins, and transparent FX to industries riddled with opaque mark-ups, kickbacks, and physical cash transactions.

Backed by renowned VCs Addition and Atlantic Labs, Kadmos has raised more than $39 million since 2021. The company intends to use the funding for expanding across industries and further accelerating product development. For more information, visit https://www.kadmos.io/

**Live in Kadmos3’s hiring system.** Read from the company's own applicant tracking system, not reposted from a job board — so it's a real, open requisition rather than an ad that outlived the role.

We remove it as soon as it disappears at source.
