What are the responsibilities and job description for the Senior Inkjet Application Engineer position at Dandy?
Dandy is transforming the massive and antiquated dental industry—an industry worth over $200B. Backed by some of the world’s leading venture capital firms, we’re on an ambitious mission to simplify and modernize every function of the dental practice through technology. As we expand our reach globally, Dandy is building the operating system for dental offices around the world—empowering clinicians and their teams with technology, innovation, and world-class support to achieve more for their practices, their people, and their patients.
Role Overview
This role blends hands-on system development with opportunities to grow into broader technical ownership.
You will work closely with printers, printheads, inks, and test systems to develop and improve real-world performance, while also contributing to system design decisions, architecture, and scaling strategies over time.
The ideal candidate enjoys working directly with hardware and experiments, and is interested in expanding their impact beyond execution into system-level thinking and technical leadership.
Key Responsibilities
This role is best suited for engineers who prefer hands-on problem solving, rapid iteration, and working directly with physical systems. Candidates with primarily theoretical or simulation-based experience may not be a strong fit.
Req ID: J-1074
For full-time positions, Dandy offers a wide range of best-in-class, comprehensive, and inclusive benefits tailored to each country where we operate. Our local benefits packages typically include healthcare, dental, mental health support, parental planning resources, retirement savings options, and generous paid time off—ensuring our team members are supported no matter where they live and work.
Dandy is proud to be an equal-opportunity employer. We are committed to building a diverse and inclusive culture that celebrates authenticity to win as one.
