E&I SPI Designer

Unity Partners on behalf of our offshore energy partner

E&I SPI Designer – Offshore Energy Projects | The Netherlands

Our partner is a leading engineering organization delivering complex offshore energy projects, including high-voltage offshore substations that play a key role in the energy transition. To strengthen their Electrical & Instrumentation design team, we are looking for an experienced E&I SPI Designer who enjoys building robust cable designs that work flawlessly long before installation starts.

In this role, you ensure that complex E&I cable systems are correctly designed, connected, and documented — providing the foundation for safe, efficient installation and commissioning offshore.

Key Responsibilities

As an E&I SPI Designer, you will:

• Design complete E&I cable infrastructures for offshore energy projects.
• Build and maintain a detailed SmartPlant Instrumentation (SPI / Intools) database containing all E&I components, cables, and terminal strips.
• Connect cables within the wiring module and ensure correct termination logic.
• Generate termination diagrams and loop diagrams using tools such as SPI, Infomaker, and AutoCAD.
• Ensure the SPI database is accurate, complete, and up to date throughout the project lifecycle.
• Work closely with E&I designers and other disciplines to align cable design with the overall engineering model.
• Minimise installation errors by delivering clear, consistent, and high-quality documentation.

Your Profile

• Completed vocational education (MBO) in Electrical Engineering or a similar technical field.
• 3+ years of experience in a similar E&I or SPI design role.
• Hands-on experience with SmartPlant Instrumentation (Intools).
• Experience using Infomaker and AutoCAD.
• Proven ability to generate wiring diagrams, termination diagrams, and loop drawings.
• Accurate, structured, and able to work independently.
• Strong communication skills and a collaborative team mindset.
• Fluent in English; Dutch is a plus.

Organization & Offer

You will join a close-knit E&I design team working within a large, multidisciplinary engineering organization. The culture is professional, informal, and focused on collaboration and shared success.

What you can expect:

• High-impact projects across sectors — from offshore wind platforms to infrastructure, industrial facilities, and marine systems.
• A professional yet friendly working environment where expertise and enjoyment go hand in hand.
• Flexible employment conditions: choose a higher salary, extra vacation days, or a combination.
• Excellent secondary benefits, including:
  • 31 vacation days
  • 7% annual bonus
  • Profit sharing
  • Flexible pension scheme
  • Travel allowance & work-from-home compensation
• Extensive opportunities for training, courses, and professional development.
