Senior Mechanical Design Engineer

Delft, The Netherlands
32–38 hours per week
MSc level or equivalent experience
5+ years relevant experience 

About the role

IMSystems is growing from a technology‑driven start-up into a product company. To support this next phase, we are looking for a Senior Mechanical Design Engineer who not only excels at mechanical design, but also helps structure and mature our engineering and product development processes.

This is a hands‑on role in a fast‑moving start-up environment. You will actively design hardware while also bringing experience from more structured engineering organizations — helping us improve how we develop products, document designs, manage interfaces, and move from concept to production.

What you will do

Product & Mechanical Design

• Lead the mechanical design of next‑generation Archimedes Drive products, from early concept through detailed design and industrialization.

• Translate product and customer requirements into robust, manufacturable mechanical solutions.

• Perform tolerance stack‑ups, basic FEA, and design validation to support design decisions.

• Create high‑quality production drawings, assembly documentation, and engineering deliverables with minimal ambiguity.

• Support prototype build, testing, and iteration in close collaboration with test and assembly engineers.

Product Development & Engineering Process

• Help structure and improve the engineering workflow, including: 

  • Design reviews and gated development phases

  • Interface definition and documentation

  • Change management and version control

  • Design for manufacturability and scalability

• Bring best practices from more mature organizations and adapt them pragmatically to a start-up environment.

• Support the transition from development projects to repeatable product platforms.

Collaboration & Leadership

• Work closely with R&D, testing, and production to ensure design intent is carried through.

• Act as a senior technical reference within the engineering team.

• Coach and support junior engineers.

• Contribute to shaping how the engineering team will grow in the future.

What we are looking for

You don’t need a PhD — we are designing and building products, not doing academic research.

Required

• MSc level of thinking, through education or equivalent practical experience.

• 5+ years of experience in mechanical design and product development.

• Strong experience in designing industrial or high‑precision mechanical systems.

• Solid understanding of manufacturability, tolerances, and production methods (steel and precision components).

• Experience working in structured engineering environments (clear processes, reviews, documentation).

• Hands‑on, solution‑oriented, and comfortable working under pressure.

• Able to work independently while collaborating closely with others.

• Fluent in English

Nice to have

• Experience bringing products from prototype to production.

• Exposure to start-up or scale‑up environments.

• Experience mentoring engineers or leading small technical teams.

• Interest in growing into a technical leadership role.

Who you are

• You enjoy solving real engineering problems, not just designing on paper.

• You are resilient and comfortable with ambiguity, priorities can shift, and prototypes don’t always work the first time.

• You combine pragmatism with high standards.

• You get energy from building things and improving how things are built.

What we offer

• A senior, impactful role in a growing deep‑tech start-up.

• Competitive salary.

• Share participation, everyone shares in IMSystems’ success.

• A high degree of ownership and autonomy.

• Direct impact on how products, and engineering processes, are built.

• Strong support for professional growth and future leadership development.

• A motivated, collaborative team working on breakthrough mechatronics technology.
