Senior Mechanical Product Development Engineer / Ent...

Berlin | Full-time | Hardware Startup

MIYOL is developing a wearable device that generates electricity while walking. We have a working prototype and are now developing it into a robust, manufacturable product.

We are looking for an experienced, hands-on mechanical engineer to take ownership of the mechanical development of the product. You will work directly on the mechanism, CAD design, prototyping and testing, with substantial freedom to shape the technical solution.

• Develop and improve the product’s mechanical architecture and mechanisms
• Design parts and assemblies in CAD
• Build, test and iterate prototypes
• Plan and perform mechanical, durability and performance tests
• Identify failure modes and improve reliability
• Select appropriate materials, components and manufacturing processes
• Develop the design toward production readiness and DFM
• Prepare drawings, BOMs and technical documentation
• As the product matures, support suppliers, tooling and pilot production

• Degree in Mechanical Engineering, Mechatronics, Product Development or a related field
• Several years of hands-on mechanical product development experience
• Experience developing physical products from prototype toward production
• Strong mechanical design and CAD skills
• Practical prototyping and testing experience
• Good understanding of tolerances, materials and manufacturing processes
• Ability to work independently and take ownership of technical problems

Experience with compact electromechanical products, mechanisms, transmissions, injection-moulded parts, wearables, medical devices or consumer hardware is a plus.

German is helpful but not required; English is sufficient for the role.

You’ll join MIYOL at an early stage and have significant influence over how the product develops. This is a role with real technical ownership rather than a narrowly predefined engineering scope.

The current salary budget is €70,000–€72,000 gross per year. We are also open to discussing equity as part of the overall compensation package.

If you enjoy turning working prototypes into real products and want to own the mechanical development of an early-stage hardware product, we’d like to hear from you.
