You'll need to have hands‑on experience, developing complex assembly processes and the ability to thrive in a fast‑paced, evolving, and highly innovative environment.

What You’ll Do

• Be the technical lead of developing joining technologies (focus bonding/laser welding)
• Install and develop new bonding/laser welding processes
• Develop a robust process window for bonding/laser welding in series production for possible variations in the process
• Install and train online quality measurement systems to control the process in series production
• Set requirements for parts (materials/geometry) and tools (for welding)
• Define specifications for machines, tools and facilities
• Plan and assure that targets are achieved on time within the expected quality & costs
• Conceptualize, bring‑up, prototype, test and deliver production welding processes, R&D and in‑line validation processes
• Review and approve documentation including drawings, schematics, and detailed procedures
• Ensure internal validation of the overall systems
• Support testing and analyses in other areas of engineering or development
• Support the transition to the manufacturing line

What you’ll bring to Stark

• Mechanical Engineering degree or similar
• Deep experiences in joining technologies with focus on bonding and laser welding
• Experiences in teaching automated welding machines with different materials & geometries
• Experiences in designing tools for welding and setting requirements for the parts and tools
• Strong analytical & problem‑solving skills
• Comfortable in a fast‑paced, ever‑evolving, highly innovative environment (startups or high‑tech companies)
• High standards for yourself and everyone you work with
• Constantly looking for ways to innovate, improving your products performance, quality, and cost
• Outstanding communication and interpersonal skills, fluent English is a must
