Your mission Join us at the forefront of industrial innovation. As a Senior DFM Engineer, you’ll lead the industrialization of our next-generation 3D printers—bridging design and production to deliver scalable, robust, and high-performance hardware systems. In this high-impact role, you’ll own the manufacturability process, from early concept reviews to ramp-up and serial production. Working as part of a tightly-knit, 7-person hardware team, you’ll operate in a fast-moving environment with flat hierarchies and direct access to decision-makers, suppliers, and engineering leads. You will define the manufacturing strategy from the ground up—setting quality standards, implementing cost-efficient processes, and guiding cross-functional teams across prototyping, sourcing, and production scaling. If you are passionate about building world-class hardware and ready to shape the production backbone of our future technologies, we’d love to hear from you. Your profile Your Role Act as the subject matter expert in hardware manufacturability setting technical benchmarks and mentoring engineers across departments. Design, optimize, and scale the manufacturing of next-generation 3D printers turning complex hardware concepts into production-ready systems. Lead manufacturability assessments and implement design improvements that streamline production and reduce cost. Own the industrialization process end-to-end from early design feedback through supplier ramp-up, quality validation, and documentation. Maintain a hands-on role analyzing components, testing prototypes, and solving design-for-manufacturing challenges directly with engineering and production teams. Define and refine production strategies across technologies like additive manufacturing, CNC machining, and injection molding. Develop and maintain technical documentation, including assembly instructions, inspection standards, and supplier guidelines. Collaborate with internal teams and external manufacturing partners to source, validate, and scale high-precision components. Ensure all components meet our standards for quality, cost-efficiency, and production scalability. Solve complex production challenges with creativity and a pragmatic, solution-oriented mindset. Your Profile We’re looking for a senior-level manufacturing engineer with deep technical know-how and a proven ability to bring complex hardware to life at scale. Degree in mechanical engineering, production engineering, or a related field. 8 years of experience in manufacturing engineering or hardware industrialization. Expertise in both additive and traditional manufacturing processes (e.g. CNC machining, sheet metal, injection molding). Experience driving DFM processes and transitioning prototypes to serial production. Proficiency in CAD for component analysis and design iteration. Strong understanding of material behavior, tolerancing, and quality standards in mechanical systems. Hands-on approach and comfort working closely with production teams and suppliers. Strong communication skills and a collaborative mindset. Proficient in German and English. Portfolio or project references demonstrating manufacturability improvements and scaled production rollouts. Why us? Join Us We are an early-stage startup redefining how shoes are made—powered by 3D printing and a bold vision.
