Your Profile
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
- A degree or equivalent in Business, Economics or Engineering
- 3-5 years of experience in customer-facing roles (e.g. Sales, Project Management, Key Account Management) in the energy industry
- Track record of managing relationships with senior external stakeholders (e.g. senior leadership, C-suite, commercial directors)
- Excellent problem-solving skills, clear sense of ownership and a proactive mindset
- Experience with data analytics and performance dashboards for asset management
- Solid understanding of-or high willingness to quickly learn-energy asset performance metrics, grid regulations, and trading frameworks

Skills to Set You Apart
- Experience in BESS or renewable energy project development

- Hands-on experience working with cross-functional teams especially with software engineers and data scientists
- Familiarity with agile working methods and tools
- Comfortable handling difficult conversations, managing urgent client concerns, and balancing strategic priorities under tight timelines
This role may not be a fit for you if…
- You’re not comfortable working across teams or having bilateral unprepared conversations with clients
- You prefer routine over dynamic, evolving work environments
- 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
- You look for a pure management position - we’ll need you to be active operationally as well
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.
A Short Note from Your Future Lead
"Hi there,
I’m Aleksandra, and I’m Country Manager Poland at Entrix. Over the past years, I’ve worked with some of the largest renewable energy investors across Europe. I’ve negotiated PPAs, built commercial partnerships, developed new services like battery optimization, and managed a portfolio of over 1.7 GW. I’ve worked on both strategy and execution, and I’ve seen first-hand how fast this market is evolving.
At Entrix, we’re building something ambitious - a smart, tech-driven platform to unlock the full value of battery storage in energy markets. In Poland, this means we’re often first movers. We work at the intersection of energy markets, technology and regulation. The projects are complex, the landscape is evolving quickly, and our customers rely on us to help them make their battery projects bankable and successful.
To succeed here, three things matter most: agency, adaptability, and accountability. We need people who take ownership, drive things forward without waiting to be asked, and are ready to adjust course as the market shifts.
If you’re someone who enjoys turning ideas into action, solving real-world problems, and working closely with a tight-knit and ambitious team, I believe you’ll enjoy being part of what we’re doing here.
Looking forward to what we’ll create together,
Aleksandra"
