As a Domain Expert ESS at Alfen, you combine technical expertise with commercial insight to support our sales and product teams in developing competitive, technically sound, and customer-focused energy storage solutions. You ensure our customers always receive the best possible solution.

What will you do?

As Domain Expert ESS, you are the go-to specialist in the field of energy storage within Alfen. You support the sales process from start to finish: identifying opportunities, translating customer needs into feasible and profitable ESS solutions, and helping close deals. You act as a sparring partner for both customers and internal departments such as sales, product management, and R&D.

You provide input to our product and R&D teams based on market insights and customer feedback. During project execution and maintenance, you are the first point of contact for technical challenges within your domain.

Your responsibilities include:

  • Analyzing and translating market and customer needs into suitable ESS solutions
  • Applying solution architecture methodologies and best practices within your domain
  • Ensuring technical, operational, and maintenance feasibility of solutions
  • Supporting and advising sales, bid management, and solution architects in creating winning proposals
  • Safeguarding solution consistency throughout the entire project lifecycle (from engineering to maintenance)
  • Acting as an expert in technical issues and escalations for customers and internal teams
  • Identifying risks and proactively proposing mitigating measures
  • Maintaining relationships with internal and external stakeholders, including suppliers

What do we ask of you?

You are analytically strong, communicative, customer-oriented, and have in-depth knowledge of energy storage technologies. You can translate complex technical issues into clear solutions and enjoy working in multidisciplinary teams. Additionally, you have:

  • A completed university-level (WO) education
  • At least 3 years of relevant work experience
  • Deep knowledge of technologies within the ESS domain and related markets
  • Ability to develop creative solutions in multidisciplinary teams within Alfen, with customers and external partners
  • Excellent communication skills (spoken and written) in both Dutch and English

What do we offer?

At Alfen, we offer a responsible and independent role with room for your own input, new ideas, initiatives, and entrepreneurship. You’ll also benefit from:

  • A competitive salary with conditions according to the Metalektro CAO
  • Flexible working hours and the possibility to work partly from home
  • 27 vacation days + 13 ADV days per year, with the option to sell 10 vacation days
  • A company phone and laptop
  • Free and unlimited access to our online learning platform
  • Engaged colleagues and fun activities organized by our staff associations AlFun and Young Alfen
  • Free sports activities via Alfen to stay physically and mentally fit, including participation in sports events
  • Pension scheme via PME Pension Fund, with Alfen covering more than half of the premium

Where will you work?

You’ll join our business line for energy storage (ESS), where we develop advanced systems for large-scale applications. Alfen is a leading player in the energy transition and is growing rapidly — both nationally and internationally. Within ESS, you’ll work closely with sales, engineering, production, and service, and play a key role in delivering successful projects.
