Business Development Manager - 100%

Tethys Robotics develops innovative robotic solutions for subsea inspection & investigation operations in challenging conditions. We serve clients such as 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. Backed by strong funding and entering an exciting phase of international growth, we are looking for a driven and entrepreneurial person to help scale Tethys Robotics.

Tasks

This is not just about selling robots. You will take on a three-in-one role across sales, business development, and key account management, understanding customer problems, building long-term trust, running demonstrations in the field, closing complex deals, and bringing operational feedback back into the product.

Working side by side with our founders, engineers, and partners, you will help bring our underwater robots into real-world operations across defense, maritime security and offshore energy. Expect a hands-on role with international travel, live demos, trade shows, and customer visits in challenging operational environments.

We are looking for someone with high ownership, strong people skills, curiosity for robotics, and the ambition to help build something that has not really been done before. If you are excited by cutting-edge technology, enjoy working with people, and want to grow fast in a startup environment, we would love to hear from you.

Own the full sales cycle in our priority markets: from prospecting and active outreach to closing deals.

Lead contract negotiations and take responsibility for bringing deals across the finish line.

Represent our technology where it counts: customer visits, online meetings, international trade shows, and live demonstrations in the field.

Build long-term relationships with decision-makers, bring market insights back into the team, and help position Tethys Robotics successfully within our target markets.

Co-develop go-to-market and partner strategies together with the biz team and management (e.g. resellers, agencies, distributors).

Develop tailored proposals in close collaboration with our engineering and biz team
