Senior Machine Designer

About Sirona Technologies

At Sirona Technologies, we are developing direct air capture (DAC) technology to remove CO2 from the air and combat climate change. As a startup in the R&D phase, we’re rapidly scaling our laboratory prototype into larger, game-changing machines to be produced in large series.

We are looking for an exceptional and mission-driven machine designer to support the development and scaling of our direct air capture machine. As a member of the core team, you will be expected to rapidly grow your responsibilities to meet our ambitious goals.

Responsibilities

As a machine designer, you will have to:

• Oversee the integration of subsystems within the machine by closely collaborating with the R&D team.
• Create technical drawings and 3D models of machine components, ensuring they are manufacturable and optimized for series production by applying Design for Manufacturing principles.
• Propose continuous improvements as we scale up our manufacturing batches.
• Collaborate cross-functionally with engineering, research, and production teams to ensure design alignment and seamless project execution.
• Introduce and address prototyping and manufacturing constraints to streamline production processes and ensure product scalability.
• Support the manufacturing, assembly, and validation of products, ensuring they meet performance and quality benchmarks.
• Ensure that the product complies and gets certified for the operation site norms.
• Participate in building, testing and troubleshooting of products, analyzing results, and implementing design improvements to simplify its manufacturing, and to enhance its reliability and performance.

Requirements

• A background in mechanical, mechatronics, or electro-mechanical engineering (or equivalent experience)
• Proven - at least 5 years - experience in transitioning prototypes to scalable, mass-producible machines, with a strong focus on design for manufacturing (DfM) and assembly (DfA).
• Strong knowledge of manufacturing techniques such as CNC machining, sheet metal fabrication, casting, and injection molding, including material selection for scalability.
• Experience implementing quality control processes, tolerancing (GD&T), and ensuring compliance with relevant certifications and standards (e.g., ISO, CE, UL).
• Strong English verbal and written communication skills
• Strong problem-solving skills
• Creative, curious. Smart but humble, with a bias for action
