Delfos Energy Tech Stack

AI monitoring platform for renewable energy asset performance and predictive maintenance

Software Development Barcelona, Catalonia 51–200 employees Founded 2017 Privately Held

Delfos monitors over 15 GW of installed renewable capacity across wind, solar, hydro, and battery storage assets globally. The stack reflects a modern SaaS operation—React/Vue/Angular frontend, NestJS backend, Kubernetes orchestration on AWS—with active adoption of AI coding tools (Claude, GitHub Copilot, Windsurf) embedded in development workflows. Current hiring leans sales-heavy (3 of 8 roles) alongside ongoing engineering and support expansion, while internal projects focus on AI-driven account automation and new dashboard APIs, suggesting a pivot toward more sophisticated customer engagement tools beyond pure asset monitoring.
