Designation: Senior Software Engineer
Skills: Firmware Developer
Qualification: BE in IT/E&TC/ Computers or equivalent
Location: Pune
Experience: 4-6 Years
Required Technical Expertise:
We are seeking a highly skilled Senior Embedded Firmware Engineer with proven experience in developing firmware for smart lighting solutions. The role demands strong expertise in lighting protocols and wireless connectivity (Zigbee, BLE, Wi-Fi, Z-Wave, DALI, DMX, 0–10V) to design, optimize, and deliver advanced IoT-based lighting control systems. The ideal candidate will bring a blend of embedded firmware expertise, lighting domain knowledge, and hands-on protocol integration experience to build scalable and reliable connected lighting products.
Key Responsibilities:
- Development of embedded firmware for smart lighting products using Zigbee, BLE, Wi-Fi, Z-Wave, and traditional lighting protocols (DALI, DMX512, 0–10V).
- Integrate and customize lighting control stacks (Zigbee ZCL – Lighting Clusters, BLE Mesh Lighting Models, Z-Wave Lighting Command Classes).
- Ensure interoperability with lighting ecosystems (Zigbee Home Automation, Matter, BLE Mesh Lighting, Smart Energy, etc.).
- Debug, troubleshoot, and optimize lighting communication stacks, wireless performance, and real-time responsiveness.
- Collaborate with hardware, software, mechanical, and QA teams for complete lighting product lifecycle development.
- Optimize firmware for low-power lighting devices (sensors, switches, luminaires).
- Conduct protocol performance analysis, network scalability testing, and lighting scene management optimization.
- Create technical documentation
- Experienced in implementing secure development methodologies, ensuring robust protection of sensitive data and systems integrity.
Required Skills & Qualifications:
- Bachelor’s/Master’s in Electronics, Communication, or Embedded Systems Engineering.
- 3-7 years of embedded firmware development experience with focus on IoT and lighting applications.
- Strong expertise in C/C++ for real-time embedded systems.
- Hands-on experience with Zigbee (ZCL Lighting Clusters, ZHA, ZSE), BLE Mesh (Lighting Models), Wi-Fi, Z-Wave (Lighting Command Classes).
- Practical knowledge of lighting control protocols: DALI, DMX512, 0–10V, PWM dimming.
- Experience in RTOS-based systems and low-power design for lighting nodes.
- Familiarity with debugging tools (JTAG, Logic Analyzer, Oscilloscope) and protocol analyzers (Ubiqua, Wireshark).
- Strong problem-solving, debugging, and optimization skills.
- Preferred Skills
- Experience with MCUs used in lighting applications: Silabs (EFR32), Nordic, TI, STM32.
- Exposure to Matter (CHIP) and its Lighting Device Types.
- Knowledge of smart lighting ecosystems (Philips Hue, Leviton, Lutron, etc.).
- Experience developing dimmable, tunable-white, or RGB/RGBW lighting solutions.
- Familiarity with safety, compliance, and certification processes for lighting products.
