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.
Tasks
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
Requirements
- 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
