Senior Firmware Engineer

Position Summary

We are seeking a highly skilled Senior Firmware Engineer to design, develop, test, and maintain embedded firmware for next-generation connected products. This role requires strong hands-on experience with embedded C, real-time operating systems, and microcontroller-based development, with particular emphasis on Renesas chipsets.

Key Responsibilities

• Design, develop, debug, and maintain embedded firmware using C for microcontroller-based systems.
• Develop firmware running on real-time operating systems, including task scheduling, inter-task communication, timing, synchronization, and resource management.
• Bring up and integrate firmware on Renesas-based platforms, including peripheral configuration, board support packages, bootloaders, and device drivers.
• Work closely with electrical engineering teams to support hardware bring-up, schematic review, board validation, and root-cause analysis.
• Develop and maintain low-level drivers for interfaces such as I2C, SPI, UART, USB, CAN, Ethernet, GPIO, ADC, PWM, and similar embedded peripherals.
• Participate in firmware architecture, design reviews, code reviews, and technical decision-making.
• Implement robust, maintainable, and testable firmware for commercial or industrial embedded products.
• Debug complex firmware and hardware interactions using oscilloscopes, logic analyzers, JTAG/SWD debuggers, and other lab equipment.
• Support integration of embedded systems with higher-level software, connectivity stacks, and cloud-based services.
• Create and maintain technical documentation, including requirements, design specifications, test plans, and release notes.
• Collaborate with cross-functional teams to deliver high-quality products on schedule.

Required Qualifications

• Bachelor’s degree in Electrical Engineering, Computer Engineering, Computer Science, or a related technical discipline.
• 7+ years of professional embedded firmware development experience.
• Strong programming experience in embedded C.
• Hands-on experience developing firmware for real-time operating systems such as FreeRTOS, ThreadX, Zephyr, embOS, or similar.
• Experience developing firmware for Renesas microcontrollers or microprocessors, including use of Renesas development tools, SDKs, BSPs, or IDEs.
• Strong understanding of embedded systems concepts, including interrupts, timers, DMA, memory management, bootloaders, power management, and communication protocols.
• Experience with firmware debugging tools such as JTAG/SWD, oscilloscopes, logic analyzers, and protocol analyzers.
• Familiarity with common embedded communication interfaces including SPI, I2C, UART, USB, CAN, and Ethernet.
• Experience with version control systems such as Git.
• Ability to read schematics and work closely with hardware engineers during board bring-up and troubleshooting.
• Strong analytical, debugging, and problem-solving skills.
• Excellent written and verbal communication skills.

Preferred Qualifications

• Experience with AWS IoT Greengrass, AWS IoT Core, or cloud-connected embedded devices.
• Experience with secure boot, firmware update mechanisms, device provisioning, certificates, encryption, or embedded cybersecurity.
• Experience with connectivity protocols such as MQTT, TCP/IP, BLE, Wi-Fi, or cellular.
• Experience developing Linux-based edge applications or integrating microcontroller firmware with embedded Linux systems.
• Experience with automated testing, CI/CD pipelines, static analysis, or code quality tools for embedded software.
• Experience in regulated, industrial, medical, life sciences, or high-reliability product environments.
• Familiarity with software development processes such as Agile, Scrum, or stage-gate product development.
