Mandatory Requirements

• 5+ years of experience in sales, business development, project origination, key account management, ideally within the energy sector, renewables, trading, or infrastructure finance

• You have a strong sense of agency: you’re someone who turns ideas into action and doesn’t just talk about change

• You operate with a growth mindset: you see challenges as opportunities, adapt fast, and are constantly learning

• You are deeply responsible: when you see a problem, you take ownership and drive toward solutions, rather than waiting to be asked

• You enjoy working in an early-stage, entrepreneurial environment where building processes, relationships, and value go hand in hand

This role may not be a fit for you if…

• You prefer roles with limited customer and cross-team interactions

• You are not comfortable working in a fast-paced, evolving regulatory and technical landscape

• You are not familiar with the Spanish energy landscape and not interested in actively building expertise in the battery storage space

Hi there — thanks for checking out Entrix.

I’m Martim, leading Sales for Iberia (Spain & Portugal). I joined in April, and we’re now building and scaling the market from the ground up.

My background is in renewables across business development, growth, sales, and M&A, with experience at OX2, Ventient Energy (now rebranded Nadara), and Vestas. Outside work I spend a lot of time with my family, I am a big football fan and love travelling. I am Portuguese and living in Madrid for a long time.

We’re at an early stage here — which means real ownership, fast pace, and the chance to shape something meaningful from day one. It’s ambitious, hands-on, and definitely not “business as usual.”

If you’re excited by building, moving fast, and having real impact, we’d love to hear from you.

Martim
Sales Director - Iberia
