Mechanical Engineer - 100%

Tethys Robotics develops innovative robotic solutions for subsea inspection & investigation operations in challenging conditions. We serve governmental organizations, large asset operators and industrial service providers operating in high-demand and mission-critical environments.

As an ETH Zürich spin-off, we are a fast-growing pioneer in underwater robotics, rooted in Switzerland. As we scale from individual systems towards the production and delivery of multiple robots in parallel, we are looking for a hands-on Mechanical Engineer to help develop, industrialize and continuously improve our robotic platforms.

You will take ownership of mechanical systems and hardware modules across the complete product lifecycle: From concept and CAD design to production, testing and field use.

Your Contribution

• Design and engineer mechanical systems, assemblies and hardware modules for our underwater robots
• Continuously improve existing designs for robustness, usability, manufacturability and serviceability
• Develop production-ready designs, drawings and assembly documentation
• Support manufacturing, assembly, testing and preparation of robotic systems for delivery
• Integrate new sensors, payloads and mechanical components
• Design and conduct validation tests and critically assess results
• Troubleshoot hardware issues and support maintenance and repairs
• Work closely with electrical, software and production teams on system-level solutions
• Contribute to the development of future generations of Tethys robotic platforms

This is a highly hands-on role: you should enjoy turning designs into physical products: From CAD and prototyping to assembly, integration and refinement.

• BSc or MSc in Mechanical Engineering, Mechatronics, Robotics or a related field
• Strong experience with 3D CAD and mechanical product development
• Hands-on engineering experience in prototyping, assembly, validation and testing
• Good understanding of manufacturing processes such as CNC machining, additive manufacturing and mechanical assembly
• Ability to design robust components and assemblies for demanding real-world environments
• At least 1–2 years of relevant industrial experience in hardware or product development
• Independent, structured and pragmatic way of working
• Comfortable taking ownership from initial concept to tested and manufacturable solution
• Strong team player who enjoys working across engineering disciplines in a fast-moving startup environment
• Fluent professional English

Bonus points if you bring:

• Onshape experience
• PLM/PDM experience
• FEA and structural analysis
• Experience with robotics, maritime systems or other highly integrated electromechanical products

• A key engineering role in one of Europe’s most ambitious underwater robotics startups
• Significant ownership over the mechanical design of our robotic systems
• The opportunity to shape both current products and future platform generations
• A direct role in scaling a complex robotic product towards repeatable multi-unit production
• A dynamic, high-performance team with a strong builder mentality and flat hierarchies
• Hands-on involvement across development, production and field testing
• Real ownership, fast decision-making and the opportunity to grow your responsibilities as the company scales
• A competitive compensation package
• A modern robotics development and production environment in the Zurich area
