About This Role
We’re a Germany-based startup building a forward-thinking, globally connected team. This role is offered through an Employer of Record (EOR) provider, ensuring full local compliance and benefits aligned with Indian standards.
Initially, the position is fully remote, with access to coworking options. Looking ahead to late 2026, we plan to expand our presence in India. We're looking for someone excited to grow with us — not just in code, but in culture. You’ll play an active role in shaping our future location, with full support from our core team — including a team member relocating to India to help build that foundation with you.
This role is ideal for someone who’s not only technically strong but eager to take ownership, help shape a new chapter, and be a bridge between teams. If you're looking for more than “just a remote job,” this might be for you.
Your focus will be on our AnyHand – a Robotic Device for Home-Based Hand Therapy. The device enables patients to perform intensive hand therapy sessions multiple times a day from the comfort of their own homes. It is regularly used with the aim of preventing contractures, improving range of motion, and reducing pain.
The device offers interactive and adaptive therapy programs, which will be tailored to the user’s needs and progress. This not only enhances therapeutic outcomes but also fosters patient motivation and independence in the recovery journey and helps them to stay committed to their therapy and achieve their goals.

About Us
Our story began with a participation in “Jugend Forscht,” a German youth science competition. There, Pascal presented a robotic hand initially designed for use in hazardous environments, such as outer space. In his pursuit to develop this into a prosthetic hand, he reached out to Dr. Eric Hanke, the chief hand surgeon and senior physician at the University Medical Center Mainz.
In discussions with our visionary and founding mentor Dr. Hanke, it quickly became clear that the market was in far greater need of an intelligent hand therapy device than a prosthetic hand.
During the conceptual phase, Dominic joined the team. Together, they started working on our first prototype. We received overwhelming feedback from therapists, physicians, and at numerous competitions, which motivated us to found LIME medical GmbH and turn our ideas into reality.
Since our founding in 2016, our team has grown steadily, and we have expanded our focus from hand therapy to general orthopedic movement therapy. Currently, we are passionately working on new products in the field of Digital Health Applications (DiGA) – the so-called “apps on prescription.” Through these innovations, we aim to provide patients with additional therapy time and help them achieve better outcomes.
