It is the entry point to mobility and energy management for businesses, fleets, partners, utilities and drivers.\nWe're hiring a full-time Senior Mobile Engineer, Charging to join our global hardware team on-site in Schenectady, NY. You'll build the native Android extensions that let our React Native apps talk to our next-generation EV charging hardware. The role is focused on the native layer, not on building full native apps. You'll write the Kotlin modules that give React Native apps access to the charger hardware, which they talk to locally over a 40-pin connector.\nThis role requires working onsite from our Schenectady, NY office five days per week.\nYour key responsibilities will include:\nBuild and maintain native Android modules in Kotlin that extend our React Native apps, exposing charger hardware to JavaScript/TypeScript through Turbo Modules, Fabric components or legacy native modules.\nImplement local charger communication over the 40-pin connector between the Android device and the charger hardware, including connection handling, message parsing and error recovery.\nWork with the Android hardware and platform APIs that reach the connector (for example serial/UART and GPIO), plus foreground services and permissions, so communication stays reliable in the field.\nDesign clear, typed JS/TS interfaces for native modules (for example Codegen specs), with predictable events, error handling and lifecycle behavior.\nDefine the app-to-hardware protocols and data contracts with the embedded and hardware engineering team.\nPackage, version and document native modules, and keep them current through React Native and Android SDK upgrades.\nBuild test harnesses, simulators and automated tests (unit, instrumentation and on-device) for native-to-hardware flows, supporting hardware and firmware validation.\nMentor less experienced engineers, and explain problems and solutions at every level, from deep technical dives to architecture and design discussions.\nWork across teams inside and outside engineering, including customer support, product management, marketing and sales.\nRequirements\nWhat Makes You a Great Fit\nA bachelor's degree in computer science, engineering, mathematics or a related field, or equivalent experience.\n6+ years of professional software development, including 4+ years of Android development in Kotlin (Java a plus).\nExperience writing native modules or extensions for React Native (Turbo Modules, Fabric or legacy native modules), or for similar frameworks such as Flutter platform channels or Capacitor plugins.\nWorking knowledge of JavaScript/TypeScript, and of how React Native's native layer (JSI, Codegen, the bridge) passes data, events and work between threads.\nHands-on experience integrating Android with physical hardware over wired interfaces, such as serial/UART, GPIO or USB, on phones, tablets or embedded Android devices.\nA strong grasp of Android threading, coroutines, background execution limits and runtime permissions.\nComfort debugging across the app and hardware boundary, using tools like serial monitors, logic analyzers and logcat.\nFamiliarity with Scrum or Kanban, the full SDLC and testing practices.\nClear communication with engineering and non-engineering stakeholders, and good task management.\nWillingness to work in person at our hardware manufacturing facility in Schenectady, NY.\nNice-to-Have Skills\nFamiliarity with hardware interfaces and protocols such as UART, I2C, SPI, CAN and GPIO.\nAOSP or custom Android hardware (kiosks, embedded displays, payment terminals).\nExperience in EV charging, energy, IoT, connected devices or smart hardware, including OCPP or UL 1998.\nBuilding test apparatus for hardware or firmware validation. • General electrical safety knowledge.\nCompensation and Benefits\nThe base salary range for this position is $ 95,000-$145,000 per year\nEligibility for an annual performance bonus and additional benefits.\nFinal compensation will be determined based on experience and qualifications.\nWhy Join Nayax\nMake a tangible impact by building tools that are used across a global support organization.\nTake ownership from day one and see your work drive measurable business outcomes.\nCollaborate with experienced engineers, product leaders, and support experts across the company.\nWork in a high-growth environment where your ideas can quickly become reality.\nBe part of a global fintech leader transforming how people pay, engage, and do business.\nLearn More about Nayax\nFounded in 2005, Nayax is a global fintech leader providing end-to-end payment, consumer engagement, and business management solutions.
