• Drive business development and customer acquisition for utility-scale battery storage systems in Poland

• Own the end-to-end commercial relationship with our clients — from first meetings to signed contracts and go-live

• Translate customer needs into structured proposals and offers, working closely with the technical and operations teams

• Understand project structures, financial expectations, and regulatory contexts to shape attractive business models

• Represent Entrix at conferences, pitch meetings, and industry events to grow our visibility and network

• Contribute to the strategic positioning of Entrix’s commercial offering in Poland

• Help shape and improve our commercial and onboarding processes, based on your hands-on experience with customers

We’re looking for someone who is deeply proactive and accountable - someone who doesn’t just identify problems but owns them, and is energized by bringing clarity and progress to complexity.

Mandatory Requirements

• 3+ years of experience in business development, project origination, key account management, or energy markets

• Strong knowledge of the Polish energy landscape, ideally including renewables, grid-scale storage, or power trading

• Excellent communication and negotiation skills in Polish and English

• Experience building strong, trust-based relationships with senior stakeholders and project developers

• A proactive, self-starting mindset — you don’t wait for permission to create impact

• Full ownership of your projects — you see obstacles as opportunities to act, not as reasons to stall

• High adaptability and comfort with change — you embrace learning and iteration in a dynamic

Skills to Set You Apart

• You bring a proven track record in originating BESS projects and closing commercial agreements with developers or investors

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

• 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 Polish energy landscape and not interested in actively building expertise in the battery storage space

We are committed to diversity - of all backgrounds and experiences. You don’t need 100% of the preferred qualifications to add incredible value to our team. If you’re passionate about what you could accomplish here, we’d love to hear from you.
