About Sirona Technologies

At Sirona Technologies, we are developing direct air capture (DAC) technology to remove CO2 from the air and combat climate change. We are a young startup and are now scaling up our prototypes into industrial machines ready for mass production.

We are looking for an exceptional and mission-driven build & test engineer for the construction and assembly of our next-generation direct air capture machines. As a key member of the team, you will play a pivotal role in ensuring that our machines are built efficiently, to specification, and on schedule.

Responsibilities

As a Build & Test Engineer, you will:‍

• Work hands-on in the workshop to build our DAC machines, mechanical, electrical, and fluid systems included
• Oversee the integration and assembly of mechanical, electrical, and pneumatic systems to meet design specifications.
• Design and build test set-ups to validate components, subsystems, and full DAC machines
• Develop and manage detailed build planning for the assembly and build process, ensuring compatibility of responsible engineers’ schedules.
• Thinking creatively to find hacks that will provide the same results but much faster or much cheaper. Share feedback to designers.
• Collaborate closely with engineers and technicians to simplify & accelerate assembly processes
• Contribute to the scale-up of our manufacturing lines to build machines in large series
• Conduct inspections and quality checks during the build process to ensure compliance with design and safety standards.
• Manage the workshop setup, safety, and workflow. Ensure that the team follows safety protocols, maintaining a safe and organized work environment.

Requirements

• Bachelor’s or Master’s degree in Mechanical Engineering, Electro-mechanical Engineering, Electrical Engineering, Industrial Engineering or a related field with a focus on practical engineering
• Experience building hardware from the ground up. Hands-on experience with designing or executing hardware tests.
• Strong understanding of mechanical, electrical, and pneumatic system integration and troubleshooting.
• Agile and creative mindset that can hack common problems with out of the box ideas
• Excellent organizational skills, with the ability to manage multiple priorities and coordinate resources effectively.
• Hands-on, proactive, and mission-driven, with a commitment to building high-quality machines that deliver real-world impact.
• Strong English verbal and written communication skills
• Strong problem-solving skills
• Smart but humble, with a bias for action

Nice to haves

• Familiarity with manufacturing processes (e.g., CNC machining, metal fabrication, component sourcing) and material management.
• A strong network of suppliers (machinists, metal cutters, injection molders, etc.) and knowledge of the strengths and weaknesses of global supply chains (e.g., Europe vs. China).
