Senior Project Engineer ESS (m/w/d)

Become a Senior Project Engineer ESS at Alfen! Contribute to the smart technology that powers Europe's energy infrastructure. Translate customer needs into advanced electrical designs and help shape innovative, safe and sustainable battery energy storage projects.

What will you do?

As a Senior Project Engineer ESS, you hold technical responsibility for modular energy storage projects - from the initial sales proposal all the way to a fully installed, tested and commissioned system. You work closely with project managers, installation managers, designers, production teams and customers to deliver high‑quality, compliant and safe solutions.

Your main responsibilities include:

• Translating customer requirements into creative, functional and technically robust electrical designs.
• Designing, reviewing and optimising electrical schematics, technical drawings and bills of materials.
• Performing electrical calculations and ensuring compliance with national and international standards (including IEC guidelines).
• Coordinating with internal and external technical teams to ensure alignment and consistent project execution.
• Supporting product, FAT and control system testing on site.
• Providing technical input during both pre‑sales and after‑sales phases.
• Actively contributing to product improvements, quality enhancements and standardisation within BESS solutions.

What do we ask of you?

We focus on technically strong engineers who can translate complex customer requirements into practical, future‑proof electrical designs. You are analytical, precise and thrive in a project‑driven engineering environment. You bring:

• A bachelor's or master's degree in Electrical Engineering, Energy Systems, Energy Technology or a comparable discipline.
• In‑depth knowledge of energy systems and experience analysing and improving electrical drawings.
• Experience with MS Office, PDM and ERP systems.
• The ability to organise your work systematically and coordinate across multidisciplinary teams.
• A proactive, innovative mindset and strong problem‑solving skills.
• Good command of the English language; Dutch is a plus (language courses are available).
• A VCA VOL certificate, or willingness to obtain one.

These qualifications perfectly match our target group: analytical and structured engineers with a strong electrical foundation who want to make an impact in energy storage projects.

What do we offer you?

At Alfen, you work on technology that truly makes a difference. You will join an innovative, international organisation where initiative and development are encouraged. We offer:

• An attractive salary in line with the Metalektro Collective Labour Agreement.
• 27 vacation days + 13 ADV days per year.
• Flexible working hours and hybrid working options.
• Travel allowance (€0.23 per km, up to 50 km one way).
• A solid pension scheme via PME, with a generous contribution from Alfen.
• Access to our extensive learning and development platform.
• A close‑knit team, short communication lines and a modern, innovative working environment.

Where will you work?

You will work at Alfen's headquarters in Almere, where engineering, production and project management operate closely under one roof. From this central hub, you contribute to European energy storage projects that directly accelerate the energy transition.
