Flosum builds a Salesforce-native DevOps and data protection platform for large enterprise teams. As we focus on pipeline generation, retention, and product velocity, we see AI as a key driver for progress. We are hiring our first AI Go-to-Market Engineer to design, implement, train, and improve AI agents and automation across our revenue engine, from first contact through closed deals and expansion. This is a remote role based in Poland. Role Overview This position goes beyond prompt engineering. It is a hands-on builder role, reporting directly to the CEO.
