Senior Inkjet Application Engineer

Dandy is transforming the massive and antiquated dental industry-an industry worth over $400B. 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 OverviewThis 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 Responsibilities1. Inkjet System DevelopmentDesign and develop inkjet printing systems from concept through productionIntegrate industrial printheads (Seiko, Epson, Xaar, Ricoh, Kyocera)Own system-level performance including jetting stability, placement accuracy, and reliability2. Printhead & Waveform EngineeringDevelop and optimize drive waveforms for stable drop formationDiagnose and resolve jetting issues including satellites, misfires, cross-talk, and air ingestionOptimize drop velocity, volume consistency, and firing reliabilityUnderstand and troubleshoot print quality issues (banding, missing jets, color inconsistency, placement errors) and trace root causes across waveform, ink, hardware, and process variables3. Ink & Fluid Systems IntegrationDefine ink operating windows (viscosity, surface tension, temperature)Collaborate with ink chemistry teams to align formulation with hardware constraintsEvaluate real-system ink behavior and long-term stability4. System Integration & DebuggingIntegrate and troubleshoot across fluid systems, motion systems, and electronicsDebug issues end-to-end without reliance on siloed teamsImprove robustness and repeatability of system performance5. Experimental Design & Data AnalysisDesign and execute structured experiments (DOE)Develop test methods for jetting reliability, print quality, and durabilityAnalyze data to drive engineering decisions and system improvements6. Production Readiness & ScalingSupport transition from R&D to manufacturingDefine specifications, tolerances, and quality control proceduresImprove machine-to-machine consistency and field reliabilityRequired Qualifications5-10+ years of hands-on inkjet system development experienceExperience with industrial printheads (e.g., Seiko, Epson, Xaar, Ricoh, Kyocera)Strong understanding of drop formation physics and waveform tuningPractical experience with fluid systems (pressure control, degassing, filtration)Demonstrated experience building and debugging real inkjet systemsPreferred QualificationsExperience in functional or materials printing (ceramics, electronics, biomaterials)Familiarity with color science and calibration workflows (Lab, ΔE, ICC profiles)Experience with multi-head alignment and system calibrationExperience collaborating with cross-functional engineering teamsWhat Success Looks LikeIndependently diagnose and resolve jetting and system-level issuesRapidly iterate and improve system performance under real-world constraintsDeliver stable, repeatable printing performance across machinesContribute to systems that successfully transition into productionAdditional NotesThis 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-1074For full-time positions, Dandy offers a wide range of best-in-class, comprehensive, and inclusive benefits tailored to each country where we operate.
