Job description

Work Flexibility: Hybrid or Onsite

Stryker presents an exciting opportunity to join a highly motivated R&D team in developing key technology to enable the evolution of new surgical techniques in electrosurgery. The successful candidate will work with a multi-disciplined team at our Innovation Centre in Cork and focus on establishing the needs of our customers while designing and bringing innovative solutions for electrosurgery applications to market.

The Innovation Centre, which features unique design and collaboration workspaces, state-of-the-art prototyping and test facilities, and a simulated operating room, is the first of its kind in Ireland. The centre focuses on the development of new technologies and products to improve patient safety and outcomes during surgery, and increase operating room efficiency across multiple surgical specialties including neuro, spine, ENT and orthopaedic surgery.

The successful candidate will design, develop, refine and evaluate electro-mechanical components, assemblies or subsystems for electro-mechanical medical devices.

You will use concurrent engineering and rapid prototyping techniques to reduce product time to market whilst adhering to project deadlines and product costs. You will plan and execute successful product development projects, occasionally leading and training team members on technical aspects of product commercialization.
