Embedded Software Engineer

Join a Residential & Robot Charging team that builds the full software stack for home, multi-family, and humanoid-robot charging products, including mobile and wall-connected EV chargers and an advanced robot charger. You will design and deliver secure, grid-interactive IoT firmware that keeps safety-critical systems running reliably around the clock, supports seamless over-the-air updates, manages dynamic loads across many units, and enables vehicles to power homes and support energy billing and reimbursement. This role offers the opportunity to work on cutting-edge charging technologies that will scale to support millions of robots and connected devices., * Own major firmware subsystems end-to-end, from gathering requirements and defining architecture through implementation, validation, and ongoing fleet monitoring.

• Design and implement safety-critical, real-time software in C and C++ on RTOS and embedded Linux platforms for connected charging products.
• Lead protocol implementation and certification efforts for OCPP 2.0.1, ISO 15118-2/-20 (Plug and Charge), DIN standards, and emerging robot-charging standards.
• Develop and optimize wireless communication stacks and mesh topologies using technologies such as Wi-Fi and Bluetooth Low Energy, as well as wired communication interfaces including Ethernet, PLC, and CAN-FD.
• Collaborate closely with mobile, backend, and hardware engineering teams to deliver complete features such as PowerShare, scheduled charging, and site-level load balancing.
• Drive test automation for firmware, including unit tests, software-in-the-loop (SIL), hardware-in-the-loop (HIL), and fault-injection testing, and integrate these into robust CI/CD pipelines.
• Provide technical mentorship to other engineers, share best practices, and set a high quality bar for firmware design, implementation, and testing.
• Contribute to continuous improvement of system reliability, security, and performance across a large and growing fleet of connected charging devices., You will work in a product-focused environment that owns the firmware for two EV chargers-a mobile connector and a wall connector-as well as the charging systems for a humanoid robot platform. The team operates at the intersection of embedded systems, power electronics, connectivity, and robotics, with a roadmap that includes advanced capabilities such as vehicle-to-grid (V2G) energy export. You will collaborate closely with mobile, backend, and hardware teams and spend time both in the lab and in a development environment, using tools such as oscilloscopes, logic analyzers, and CAN interfaces to debug and validate high-reliability charging systems. The role centers on building secure, grid-interactive IoT devices that run 24/7, support over-the-air updates, and operate across large distributed fleets in real-world conditions.

• At least 5+ years of experience shipping high-reliability embedded firmware for connected devices.
• Expertise in embedded C programming and strong C/C++ skills in resource-constrained and real-time environments, including RTOS such as FreeRTOS, Zephyr, and bare-metal systems.
• Hands-on experience working with microcontrollers, including writing low-level drivers and configuring peripherals.
• Proven experience implementing and troubleshooting TCP/IP, TLS, HTTP, and WebSockets in embedded systems.
• Basic electronics knowledge, including understanding of Ohm's Law and practical experience using an oscilloscope.
• Ability to read and interpret electronic schematics and perform lab-based debugging using tools such as oscilloscopes, logic analyzers, and CAN tools.
• Demonstrated track record of leading cross-functional projects in a fast-moving environment.
• Strong commitment to writing clean, well-structured, and thoroughly tested code.
• Willingness and ability to learn quickly and adapt to new technologies and standards., * Hands-on experience with electric vehicle charging standards such as OCPP and ISO 15118 or DIN-based standards.
• Experience in robotics or robot-charging systems.
• Familiarity with smart-home protocols such as Matter/CHIP and HomeKit.
• Experience developing firmware on embedded Linux platforms in addition to RTOS-based systems.
• Experience implementing communication over Ethernet, PLC, and CAN-FD in embedded products.
• Experience in building or maintaining CI/CD pipelines for firmware projects.
• Experience with test automation frameworks for unit, SIL, HIL, and fault-injection testing.
• Experience mentoring other engineers and contributing to team-wide technical standards and best practices., CommunicationMentorshipBillingLife SciencesDebuggingTest AutomationProgrammable Logic ControllersElectronicsContinuous Improvement ProcessReliabilityMechanical EngineeringTroubleshooting (Problem Solving)CI/CDComputer EngineeringManufacturing EngineeringElectrical EngineeringUnit TestingEmbedded SystemsEmbedded SoftwareLogic AnalyzerDevelopment EnvironmentOscilloscopeC++ (Programming Language)Software-In-The-LoopCritical Illness InsuranceC (Programming Language)Linux On Embedded SystemsRoboticsTCP/IPWireless CommunicationsQuick LearningFirmwareANSYS MeshingInternet Of Things (IoT)Technical StandardVisionaryPower ElectronicsReal-Time Operating SystemsMicrocontrollersEmbedded FirmwareTransport Layer Security (TLS)Electric VehiclesEmbedded CTopologyWebSocketBare MetalFreeRTOSBluetooth Low Energy (Bluetooth)Wired CommunicationsAdvanced RoboticsProtocol Implementation Conformance StatementFault InjectionZephyr
