Internship Solar PV Engineer

Help design the solar and storage systems powering Spanish businesses.

At y Tú, we design and build solar PV and battery storage (BESS) systems for commercial and industrial clients, from 30 kW rooftops to 4 MW installations. As our Solar Engineering Intern, you’ll work alongside our Sales and Engineering teams to turn customer needs into technically sound, regulation-compliant system designs. Your work will directly affect the projects we build.

What you’ll do

• Design PV and BESS systems using PV*SOL and related tools, optimizing for yield, cost and customer requirements
• Prepare electrical layouts and single-line diagrams that comply with Spanish regulations (REBT, grid connection requirements)
• Support Sales with technical and commercial proposals, including sizing, yield estimates and equipment selection
• Join technical site visits to assess roofs, electrical installations and grid connection points
• Work with project management and installation teams to hand over designs and solve issues on site

Why you’ll love it

• Startup energy, group backing: y Tú is a startup within the Youdera Group. You get the pace and ownership of a small team with the resources and know-how of an established player.
• Real projects from day one: Your designs get built. No coffee runs, no shadowing-only internship.
• Learn from experienced engineers: You’ll get hands-on mentoring from a team that has delivered more than 2,500 projects.
• A path beyond design: Once you’re confident with solar design, you can grow into engineering and budgeting, technical due diligence etc.

Who we’re looking for

• Currently enrolled in your final year (BSc or MSc), or recently graduated, in Electrical, Industrial or Electronic Engineering, Renewable Energy or a related field
• Strong interest in solar PV and energy storage. Prior internships or projects in PV, especially C&I, are a plus
• Familiarity with PV*SOL, PVsyst, AutoCAD or similar tools is a plus, and we’ll train you on the rest
• Organized and able to juggle several projects, with a hands-on, customer-focused attitude
• Fluent Spanish and conversational English

What we offer

• 💸 Competitive internship compensation.
• 📍 Office in Plaza España, Zaragoza. We have a hybrid working policy: we expect you to be in the office 3 days/week and you're free to work from home the other days.
• 📄 Full-time internship for 6 months, through either a university internship agreement (convenio de prácticas) or a traineeship contract (contrato formativo).
• 🌱 Real prospects to grow with us after the internship.
• 🎉 Annual team trip and regular team get-togethers.
• 🌍 A fun, ambitious and international team.
