Embedded Software Engineer Specialist

Role Summary

The Embedded Software Engineer Specialist is a senior technical expert responsible for leading the design, development, and optimization of embedded firmware for our next-generation HVAC and IoT-connected products.

This role will drive architecture decisions, solve complex technical problems, and provide technical leadership across projects, working closely with hardware, system, cloud, mobile app, QA, and production teams. The Specialist is expected to act as a go-to person for critical technical topics, mentor other engineers, and help ensure our products meet global quality, reliability, and cybersecurity standards.

Key Responsibilities

• Lead the architecture, design, and implementation of embedded firmware in C/C++ for microcontroller-based systems (e.g. RL78, ARM Cortex-M, or similar).

• Own key modules and features related to HVAC control, communication interfaces, and IoT connectivity, ensuring scalability and maintainability.

• Define and optimize RTOS-based system designs (e.g. FreeRTOS): task structures, priorities, inter-task communication, timing, and resource management.

• Design and implement robust communication stacks (UART, SPI, I²C, CAN, Modbus, proprietary protocols), including error handling and diagnostics.

• Collaborate with cloud and mobile app teams to define end-to-end data and control flows, including MQTT, REST/HTTP, BLE/Wi-Fi provisioning, and telemetry formats.

• Drive code quality and reliability: establish coding standards, perform deep code reviews, oversee static analysis, and support automated/unit testing.

• Diagnose complex system issues involving firmware, hardware, and communication using debuggers, analyzers, and lab equipment; provide root cause analysis and long-term fixes.

• Prepare and maintain technical documentation: architecture/design documents, interface specifications, firmware guidelines, and review checklists.

• Support system integration, field trials, and mass production issue resolution in cooperation with test, production, service, and quality teams.

• Promote and apply secure coding practices; support cybersecurity and regulatory compliance for connected products (e.g. secure boot, secure update, data protection).

• Mentor and coach junior and mid-level engineers, providing technical guidance, knowledge sharing, and review feedback.

• Contribute to project planning and risk management by providing effort estimates, identifying technical risks, and proposing mitigation plans.

• Continuously monitor new technologies, tools, and best practices and propose improvements to the embedded software platform and development processes.

Qualifications & Experience

• Bachelor’s or Master’s degree in Electrical Engineering, Computer Engineering, Computer Science, or related field.

• Typically 8+ years of hands-on experience in embedded software/firmware development.

• Strong expertise in C for embedded systems; experience in C++ for embedded applications is an advantage.

• Proven experience with 8/16/32-bit microcontrollers (e.g. Renesas, STM32, NXP, or similar) and toolchains (IAR, GCC, etc.).

• Solid experience with RTOS-based systems (e.g. FreeRTOS or equivalent) and real-time constraints.

• Deep understanding of embedded fundamentals: interrupts, timers, memory (Flash/RAM/EEPROM), low-power design, bootloaders, diagnostics.

• Demonstrated ability to debug complex issues using JTAG/SWD debuggers, oscilloscopes, logic/protocol analyzers.

• Experience working in a structured development environment (Git or other version control, code review, CI/CD, issue tracking).

• Experience leading technical topics or acting as a key technical owner in multi-person projects.

• Good written and spoken English for collaboration with global teams and for producing clear technical documentation.
