The ideal candidate will combine strong hands-on coding expertise with system-level troubleshooting skills and the ability to collaborate directly with customers and cross-functional engineering teams.

Key Responsibilities :

- Design, develop, and debug embedded firmware using C and C for microcontroller-based platforms.
- Implement firmware for bare-metal systems and RTOS environments, including FreeRTOS and ThreadX.
- Develop and integrate wireless connectivity features using protocols such as BLE, Zigbee, Z-Wave, and RF.
- Analyze and resolve software defects using hardware debugging tools, including J-Link debuggers, logic analyzers, and digital oscilloscopes.
- Review hardware schematics and support PCB-level debugging to identify and resolve hardware-software integration issues.
- Contribute to embedded system architecture, feature planning, technical design discussions, and implementation decisions.
- Perform code reviews, static code analysis, and software quality checks to improve code reliability and maintainability.
- Prepare and maintain technical documentation, including requirements specifications, design documents, test plans, and test cases.
- Manage multiple engineering assignments while ensuring timely delivery and adherence to quality standards.
- Work closely with international customers, understand technical requirements, communicate solutions, and provide engineering support.
- Contribute to presales activities, technical proposals, and solution discussions when required.
- Support technical mentoring, onboarding,



and skill development of junior engineers.
- Participate in technical interviews and candidate evaluations as needed.

Required Skills and Qualifications :

- 7 years of hands-on experience in Embedded C programming and firmware development.
- 6 years of experience working with RTOS-based embedded systems and microcontrollers.
- Strong expertise in bare-metal programming, task management, synchronization, and real-time application development.
- Practical experience with microcontroller and microprocessor platforms such as PIC, ST, Atmel, NXP, or TI.
- Experience developing connectivity applications using BLE, Zigbee, Z-Wave, or other RF-based protocols.
- Proficiency in embedded debugging, fault isolation, and code-level troubleshooting using J-Link or similar tools.
- Working knowledge of static code analysis tools and Git-based version control.
- Familiarity with hardware schematics, PCB debugging, and electronic test equipment.
- Understanding of embedded software architecture, design principles, and the complete development lifecycle.
- Solid analytical thinking, problem-solving ability, and attention to software quality.
- Excellent written and verbal communication skills, with confidence in customer-facing technical discussions.
- Prior experience interacting with customers in the US or Europe is strongly preferred.

Good to Have :

- Experience with C and object-oriented programming concepts.
- Exposure to embedded GUI development using Qt or similar frameworks.
- Experience with application development on RTOS-enabled microcontrollers.
- Ability to contribute to technical proposals, solution design, and presales discussions.
- Experience mentoring junior engineers and coordinating technical deliverables across multiple projects.

Core Competencies :

- Firmware development and embedded debugging.
- Real-time operating systems and microcontroller programming.
- Wireless connectivity and protocol integration.
- Embedded architecture and hardware-software integration.
- Customer communication and technical problem-solving.
- Code quality, documentation, and project execution.
