Mechanical Design Engineer

Senior Level

Team: Engineering/RnD

Locations: Ukraine, Kyiv

Full-time (hybrid/remote — we're open to discussing the format)

Esper is a deep tech company developing wearable technologies for human augmentation. The company has an expertise in hardware and software engineering.

The company’s first product, Esper Hand, is a bionic prosthesis with intuitive myoelectric control, proportional motion control, six independent motors, and anatomical design, created for stable, more natural, and predictable everyday use. Through active investment in R&D, Esper is moving from standalone devices to technological infrastructure for wearable devices. Esper’s next release is MARS, a multisensory wearable system for more precise biosignal recognition and analysis. MARS helps users adapt to wearable devices faster, personalize their interaction with them, and expand their possible use cases.
