About Fledge
Fledge is a talent acquisition and recruitment firm focused on tech companies, helping VC-backed startups find niche tech talent across Europe and the US. The company describes itself as taking a sustainable, holistic approach to hiring, aiming to build teams that grow with the company rather than just filling roles. Fledge operates as Fledge EURL, a French entity (VAT FR62894453539).
Fledge's careers page lists open roles in Spain for engineers and product designers, but these appear to be positions at client companies rather than Fledge's own internal hires. The company's website does not provide details about a physical office in Spain or its work culture there. For international professionals, Fledge's relevance lies in its role as a recruiter connecting candidates with tech opportunities in Spain, though specific information about its local operations is limited.
