About the role

Ready to revolutionize industrial microbiology?

At Spore.Bio, we're looking for a Mechanical Engineer to work on the design and industrialization of our breakthrough devices. Reporting into the R&D team, you'll own the most complex technical challenges, drive structuring design decisions, and help take our prototypes to scalable, manufacturable products.

What You Will Do

• You'll lead advanced mechanical design of our devices: rethinking the architecture of existing prototypes, designing custom mechanical parts, and making high-impact design trade-offs that shape product performance and reliability;
• You'll drive optical-mechanical integration, working closely with R&D to ensure optical and mechanical constraints are aligned from the earliest design stages;
• You'll define the scale-up strategy for machines in development, anticipating series-production constraints, and challenging design choices through a Design for Manufacturing (DFM);
• You'll manage supplier relationships on critical parts, from requirement definition through quality validation, owning technical trade-offs and production follow-up;
• You'll help shape the mechanical team's methods and best practices.

About you

• Master's degree in mechanical engineering or a related field, with substantial experience (3-5+ years) in mechanical design, ideally in a rapid prototyping environment with small-series production;
• Strong CAD proficiency (SolidWorks or equivalent) and solid knowledge of manufacturing technologies (3D printing, CNC machining, etc.);
• Proven experience integrating optical components; expertise in opto-mechanical design is a strong plus;
• Excellent knowledge of materials and their properties, with the ability to make well-argued technical trade-offs;
• Demonstrated track record in product industrialization, from prototype to small-scale industrial production;
• Autonomy, initiative, and the ability to thrive in a fast-changing environment, comfortable challenging assumptions and proposing innovative solutions to complex technical problems.
