The role

We are searching for a Product Engineer to join a climate-tech startup based in Barcelona, developing advanced AI systems to accelerate global decarbonization. The company blends deep scientific research, AI engineering, and operational expertise to help industrial partners reduce emissions at scale. Their platform processes complex data in real time, providing actionable insights that drive measurable environmental outcomes.

In this role, you'll build and own end-to-end product features for AI-powered applications used by energy, mobility, and industrial teams worldwide. You'll work at the intersection of product, engineering, and environmental science-designing intuitive tools, building scalable systems, and solving technical challenges tied to sustainability, high-frequency data, and model integration. The team values autonomy, fast iteration, and a strong sense of mission.

Lead the development of full-stack solutions, from designing intuitive user interfaces to crafting robust backend systems.
Collaborate with cross-functional teams-AI researchers, climate scientists, and data engineers-to integrate models into practical, user-centric tools.
Architect scalable, maintainable systems capable of handling high-volume environmental and industrial data.
Experiment with and implement modern frameworks, APIs, and cloud infrastructure.
Mentor junior developers, helping cultivate a culture of growth, clarity, and high technical standards.
Automate and optimize workflows to deliver faster, more reliable solutions for internal teams and external users.

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.
