Sr. Embedded Software Engineer

Job Description This role focuses on designing, developing, and optimizing real-time firmware for current and next-generation fast DC charging systems. You will build high-quality embedded software for charging equipment, including fast chargers and adapters, and collaborate closely with hardware teams to deliver robust, scalable solutions. The position offers the opportunity to work with cutting-edge tools and practices to help create one of the most advanced electric vehicle charging networks in the world. Responsibilities Design, implement, and maintain firmware for embedded system components within fast DC charging equipment. Develop, enhance, and debug new and existing real-time firmware in C and C++ for embedded microcontrollers running RTOS. Perform hands‑on bring‑up of new products, supporting them from prototype through manufacturing and into high‑volume production. Create and maintain continuous integration tests, including unit tests, software‑in‑the‑loop (SIL), and hardware‑in‑the‑loop (HIL), to validate component and system functionality. Collaborate closely with hardware engineers to co‑design optimized solutions that meet aggressive performance and schedule targets. Focus on peripheral interfacing and communication protocols, ensuring reliable integration of interfaces such as CAN, Ethernet, SPI, I2C, UART, ADC, and PWM. Apply strong software engineering fundamentals, including architecture design, algorithm development, data structures, and modular code organization, to produce maintainable and scalable firmware. Use lab equipment such as oscilloscopes, logic analyzers, CAN tools, and soldering equipment to support integration, debugging, and validation activities. Contribute to firmware implementations for highly physical systems such as power conversion, thermal controls, or battery management where applicable. Adopt and promote a test‑driven approach by defining unit tests, validation plans, and quality checks as an integral part of the development process. Break down complex technical problems into manageable tasks and drive them to completion with a focus on quality and efficiency. Skills Degree in Computer Engineering, Computer Science, Electrical Engineering, or equivalent experience. 5+ years of professional firmware development experience. Strong proficiency in C and C++ for real‑time embedded systems. Extensive experience developing on embedded microcontrollers running RTOS. Significant experience with multithreaded embedded software design and implementation. Hands‑on experience with peripheral interfaces including CAN, Ethernet, SPI, I2C, UART, ADC, and PWM. Experience with networking protocols such as TCP, IP, and UDP. Comfort working in a lab environment using oscilloscopes, logic analyzers, CAN tools, soldering irons, and related equipment for integration and debugging. Solid understanding of software architecture, algorithm development, data structures, and modular, maintainable code design. Demonstrated ability to deliver high‑quality, production‑ready firmware in a real‑time environment. A test‑driven mindset, with unit testing, validation planning, and quality practices embedded in the development process. Strong problem‑solving skills with the ability to decompose complex issues and deliver practical solutions efficiently. Additional Skills & Qualifications Experience implementing firmware for power conversion systems, thermal control systems, battery management, or other highly physical product implementations. Familiarity with Protobuf for data serialization. Experience with UDS (Unified Diagnostic Services) or similar diagnostic protocols. Experience working on systems that integrate both firmware and hardware in high‑reliability environments. Passion for tackling challenging technical problems and continuously improving systems and processes. Work Environment This role centers on embedded firmware development for fast DC charging products, with approximately 80–90% of your time spent coding, primarily in C, on microcontrollers running an RTOS. You will work in a highly collaborative engineering environment that emphasizes modern software development practices, continuous integration, and close coordination between firmware and hardware teams. The position involves regular hands‑on work in the lab, using equipment such as oscilloscopes, logic analyzers, CAN tools, and soldering irons to bring up hardware, debug issues, and validate system performance. The work environment supports a culture of quality, test‑driven development, and rapid iteration to deliver reliable, scalable charging solutions.
