Résumé du poste

Tekskills Inc. is seeking an experienced embedded firmware engineer to design and develop robust firmware for IoT and industrial applications.

You will work across hardware, firmware, cloud, and mobile app integration, driving end-to-end lifecycle activities from concept to deployment. The ideal candidate brings 5+ years in embedded firmware, deep RTOS experience, and a track record of delivering production-grade devices for global clients.

Qualifications

• Programming Languages: Expert in C, Embedded C, with working knowledge of Python for scripting, automation, and test harness development.
• Firmware Architecture: Strong experience in RTOS-based design (FreeRTOS, ThreadX, Zephyr, or similar), real-time scheduling, interrupt handling, and inter-task communication.
• Protocols & Communication Interfaces: Proficient in CAN, LIN, Modbus, MQTT, BLE, Wi-Fi, I2C, SPI, UART, RS-485, and Ethernet.
• MCUs & Platforms: Deep knowledge of STM32 (F7, L4 series), TI Hercules, NXP, ESP32, Renesas, and similar microcontrollers.
• Device Drivers & Middleware: Development of low-level drivers for sensors, motor drivers, and peripherals with proven debugging and optimization expertise.
• Security & Reliability: Experience implementing secure bootloaders, OTA updates, encryption (AES, RSA, ECC), watchdogs, and fail-safe mechanisms.
• Debugging & Validation Tools: Proficiency with JTAG/SWD, oscilloscopes, logic analyzers, BusMaster, PCAN, and protocol analyzers.
• Version Control & Build Tools: Strong experience with Git, Makefile, CMake, Jenkins, and CI/CD pipelines for firmware release cycles.
• Compliance & Standards: Knowledge of MISRA-C, IEC 61508, and structured code reviews.
• Optimization Expertise: Skilled in low-power design, memory optimization, and real-time performance tuning for mission-critical applications.
• Experience: 5+ years of proven industry experience in embedded firmware development, preferably in IoT, industrial automation, energy, or telecom domains.
• Hands-on expertise: End-to-end firmware lifecycle architecture, design, coding, debugging, validation, and deployment.
• Delivery track record: Strong track record of delivering production-grade embedded/IoT products with large-scale field deployments.
• Mentoring & collaboration: Experience in mentoring junior engineers, reviewing code, and contributing to technical strategy.
• Exposure: Global clients/projects and working in multi-disciplinary teams (hardware, firmware, cloud, mobile app integration).
• Startup culture: Familiarity with startup culture and fast-paced R&D environments will be an added advantage.
