About Job Role
We’re looking for an experienced Senior Embedded Firmware Engineer with 5–10 years of experience to design, develop, and validate firmware for microcontroller and microprocessor-based systems powering industrial controls for fire detection and suppression systems, and other safety-critical control products.
This role focuses on embedded, real-time, wired and wireless network-connected devices. The engineer will own module-level design and implementation, support hardware integration, and contribute to system validation and regulatory compliance in industrial environments.
Key Responsibilities
Firmware Development & Architecture Contribution
- Design and implement embedded firmware modules in assembly, Python, C for either bare metal (linear programming) or RTOS-based systems.
- Contribute to scalable firmware architecture and reusable platform components.
- Follow coding standards aligned with safety-critical systems.
Real-Time Systems & Deterministic Execution
- Design and implement RTOS-based task scheduling and interrupt-driven control logic using CMX or equivalent RTOS.
- Implement watchdog mechanisms, fault detection, and safe-state transitions.
Industrial Device Drivers & Control Systems
- Develop and maintain firmware drivers for industrial and electro-mechanical components, including, Motors (BLDC, stepper, AC), Solenoids and valves, Relays, contactors, circuit breakers, Industrial sensors (pressure, flow, temperature, smoke).
- Implement PWM control, ADC/DAC interfacing, and protection logic.
- Ensure safe operation and deterministic response under fault conditions.
Networking & Wireless Integration
- Implement wired communication protocols including TCP/IP, RS485/RS232, and Modbus.
- Contribute to real-time communication implementations where applicable.
- Integrate and troubleshoot wireless technologies such as Zigbee, BLE, LoRa / LoRaWAN, Mesh networking architectures.
- Support OTA firmware updates over wired and wireless channels.
Secure Cloud Connectivity
- Implement device-to-cloud communication using MQTT/TLS or equivalent secure protocols.
- Support telemetry, provisioning, remote diagnostics, and firmware update mechanisms.
Hardware/Firmware Integration & Validation
- Participate in board bring-up, hardware debugging, and system integration.
- Use oscilloscopes, logic analysers, and protocol analysers for root cause analysis.
- Collaborate with hardware and verification teams to execute validation plans.
Compliance & Documentation
- Develop documentation required for UL/ULC/FM/FCC/CE/VDS/LPCB regulatory compliance.
- Maintain traceability of firmware features and changes.
- Support manufacturing release and production testing.
Qualifications
- Experience: 5–10 years in embedded firmware development for industrial controls and safety-critical systems.
- Bachelor’s or Master’s degree in Computer Science, Electronics, Electrical Engineering, or related.
- Strong expertise in Embedded C/C++, RTOS-based firmware design and coding, Real-time and interrupt-based systems.
- Hands-on experience with Industrial device driver development, Electro-mechanical control systems, Wired communication protocols (TCP/IP, RS485, Modbus), Wireless technologies (Zigbee, BLE, LoRa, Mesh).
- Experience with secure device connectivity (MQTT/TLS) preferred.
- Strong debugging, problem-solving, and system-level thinking skills.
- Ability to collaborate effectively in cross-functional Agile teams.
- Prior experience in regulated, safety-critical, or high-reliability domains preferred.
- Excellent communication and collaboration skills in cross-functional Agile teams.
