This role requires someone who is both hands-on and capable of taking ownership of large-scale firmware development efforts.

About CITiLIGHT

CITiLIGHT is reshaping how smart infrastructure works globally. We operate at the intersection of smart cities, sustainability, and innovation, helping city administrators and private stakeholders deploy cutting-edge IoT-led solutions at scale. As we expand our platform capabilities, we are looking for passionate and skilled engineers to help us build robust, user-friendly, and scalable applications that drive real-world impact.

Key Responsibilities:

• Design, implement, and maintain firmware in C and C++ for resource-constrained embedded systems.
• Handle large, modular codebases (20k+ lines) with clean, efficient, and maintainable coding practices.
• Work closely with the hardware team for board bring-up, debugging, and integration.
• Implement and optimize communication protocols: I²C, SPI, UART, GPIO, TCP/IP, MQTT.
• Develop test scripts in Python for automation and validation.
• Debug using serial monitors, oscilloscopes, DSOs, and logic analyzers.
• Integrate wireless and networking stacks (LoRaWAN, LTE, GSM, BLE, Wi-Fi, GPS/GNSS).
• Ensure secure firmware development, including encryption, secure boot, and OTA updates.
• Collaborate with QA and server-side teams to validate end-to-end functionality.
• Document firmware architecture, APIs, and communication protocols.
• Stay updated with emerging embedded and IoT networking technologies.
• Drive continuous improvement in firmware quality, testing, and efficiency.

Required Skills & Qualifications:

• Expert in embedded C and C++, with modern coding standards and data structures & algorithms (DSA).
• Proven experience in handling large, production-level codebases.
• Strong debugging skills with hardware tools (scopes, analyzers, JTAG/SWD debuggers).
• Solid understanding of hardware design fundamentals and ability to troubleshoot hardware issues.
• Proficiency in communication protocols (I²C, SPI, UART, MQTT, TCP/IP, GPIO).
• Experience with wireless connectivity stacks (LoRaWAN, LTE, GSM, BLE, Wi-Fi).
• Familiarity with sensor integration and low-power firmware design.
• Skilled in Python scripting for testing and automation.
• Strong Git/version control workflow experience.
• Knowledge of embedded security and best practices in secure coding.
• Excellent system design, problem-solving, and conceptualization abilities.
• Strong documentation and communication skills.

Soft Skills (Critical for Success):

• Ownership mindset: Takes full responsibility from design to delivery.
• Team collaboration: Works seamlessly with hardware, software, and QA teams.
• Clear communicator: Able to explain technical trade-offs to cross-functional teams.
• Problem solver: Approaches issues systematically and proactively.
• Adaptable & innovative: Stays current with technology trends and applies them effectively.

Nice to Have:

• Experience with RTOS (FreeRTOS, Zephyr, ThreadX).
• Exposure to IoT standards (Matter, Zigbee, DALI).
• Familiarity with CI/CD pipelines for embedded systems.
• Experience with safety-critical or certified systems (ISO 26262, IEC 61508, MISRA-C).
