Why ProtonWe are developing subcutaneously implantable wearable sensors for chronic kidney disease and heart failure patients to improve their wellbeing and save lives. Our first product will be the first ever continuous potassium monitoring platform to prevent cardiac arrhythmia in patients with heart failure and chronic kidney disease.
ScopeProton Intelligence is seeking an early–to-mid career Process Engineer with hands-on experience in microfabrication, cleanroom operations, electroplating, and wet chemistry, ideally applied to medical or biosensor devices to join our team in Melbourne, Australia.
Key ResponsibilitiesProcess DevelopmentDevelop, optimise, and maintain microfabrication processes for medical sensor devices, including:Photolithography and patterningThin-film deposition and etchingElectroplating and surface modificationSupport sensor fabrication involving bio-compatible materials and functional coatingsTranslate R&D processes into robust, manufacturable workflowsCleanroom & Startup Manufacturing SupportExecute hands-on processing in a cleanroom environmentOwn day-to-day process performance, yield improvement, and troubleshootingSupport pilot manufacturing builds and early production rampWork closely with device, chemistry, and quality teams to resolve integration issuesWet Chemistry & Electrochemical ProcessesPrepare, control, and monitor wet chemistry processes, including:Electroplating bathsChemical etching and cleaning stepsSurface treatments relevant to medical sensorsEnsure chemical handling and disposal comply with safety and regulatory expectationsQuality Systems & ISO 13485 AlignmentDevelop and maintain process documentation in line with ISO 13485SOPs, work instructions, and batch recordsContribute to process validation activities (IQ/OQ/PQ as applicable)Participate in risk management activities (e.g. PFMEA, hazard analysis)Support internal and external quality auditsEnsure traceability and change control for process updatesData Analysis & Continuous ImprovementUse process data and metrology to drive continuous improvementApply basic Statistical Process Control (SPC) and Design of Experiments (DOE) techniques to improve yield and reproducibilitySupport root cause analysis for nonconformances and process deviations
Qualifications & ExperienceEducationBachelor’s or Master’s degree in Mechanical Engineering, Chemical Engineering, Materials Science, Biomedical Engineering, or a related disciplineExperience2–5 years of relevant industryHands-on experience with microfabrication in a cleanroomExperience with electroplating and/or wet chemistry processesExposure to medical device and/or sensor fabrication environments is preferredFamiliarity with working under a regulated quality system (ISO 13485 preferred)Technical Skills (Required)Photolithography and thin-film processingWet and dry etching techniquesElectroplating process control and optimisationExperience with bio-compatible materials and surface treatmentsCleanroom metrology, characterisation and inspection methodsProcess validation and documentation practicesSPC and DOETechnical Skills (Preferred) Experience with implantable or wearable medical sensorsFamiliarity with ISO 14971 risk managementExperience with applied researchExperience scaling processes from lab to pilot productionExposure to contract manufacturers or supplier qualificationSoft skills requirementsCreativity and flexibility are keyProcess and detail orientedMust be hands-on, willing to get into the trenches and get hands dirtyFamiliar with and comfortable functioning in a small, fast-paced medical device start-up environment, NOT a big company mind-setMust be product focused, thinking big picture, designing for function and manufacturability, and test as part of the complete product -- not a component designer.Committed to building on-time and on-budget
