Job description

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 UI Software Engineer to help develop, industrialize and continuously improve our robotic platforms.

Tasks

• Develop and integrate complex UI modules, connecting disparate systems and data streams.
• Implement sophisticated real-time data visualizations.
• Implement core user interactions with robotic systems and web applications.
• Perform functional verification tests and troubleshoot issues.
• Support user interviews and help translate requirements into design input criteria.
• Work with the development team to refine the visual and interaction layer.
• Create technical documentation for user interaction and implementation.

Requirements

• 2+ years of experience with Unity (C# and uGUI) or a TypeScript framework (Vue.js or similar).
• Experience with both is a strong advantage.
• 1+ year of hands‑on experience developing real-time visualization systems.
• A passion for human-computer interaction (HCI) and the ability to translate abstract requirements into concrete, production-ready code.
• Completed education in computer science, software engineering, human-computer interaction, game development, or another highly technical engineering field with a focus on user-centric software development.
• Understanding of event-driven programming and experience applying it in software development.
• Experience working with Git version control.
• Strong problem‑solving and connected thinking skills.
• A drive to write clean, high‑quality code.
• Comfortable working in a cross-functional team.
• Good organizational skills and attention to detail.
• Fluent in spoken and written English.
• Interest in underwater robotics.

Bonus Points

• Knowledge of robotics middleware such as ROS/ROS2 and experience interfacing with live sensor data.
• Experience with map rendering and interaction logic in both 2D and 3D.
• Hands‑on experience with drones or other robotic systems.
• Experience with high‑performance rendering or computationally intensive visualizations, such as compute shaders, graphics pipelines, or point clouds.
• Knowledge of clean code practices and software design principles such as SOLID.
• Experience with automated testing, CI/CD, or GitHub Actions.
• Familiarity with concurrent programming.
• Experience with Python.

Benefits

• Collaborative culture where your ideas directly impact product development.
• A dynamic, passionate and high-performance team with a strong builder mentality and flat hierarchies.
• Streamlined decision-making processes, flat start-up hierarchies, and modern working methods that cultivate great ideas.
• Exposure to cutting-edge robot technology and hands‑on experience with real-world data processing and visualization.
• Modern office in Schlieren, Zürich.
• Attractive compensation in a startup environment.
