With over 8 years of experience, we specialize in delivering cutting-edge technology solutions that drive revenue and engagement. Our team is passionate about innovation, cloud infrastructure, and automation, ensuring high-quality software delivery at scale.

Position Overview

We are seeking an experienced Embedded Software Developer to join our team and help drive the development of next-generation IoT solutions. In this role, you will be responsible for designing and implementing robust firmware for ESP32-C6 microcontrollers using ESP-IDF, with a strong emphasis on low-power operation, wireless connectivity, and seamless cloud integration. You’ll work at the intersection of hardware and software—developing MQTT-based communication protocols, managing a variety of environmental sensors, and enabling secure OTA updates. This is a highly collaborative position that involves close coordination with mobile, backend, and hardware teams to deliver a reliable and scalable system. If you're passionate about embedded systems, enjoy solving complex technical challenges, and thrive in fast-paced environments, we’d love to hear from you.

Key Responsibilities

• Develop embedded firmware for ESP32-C6 microcontrollers using ESP-IDF
• Implement MQTT-based communication protocols for cloud integration
• Integrate and manage multiple sensors: soil moisture, temperature, humidity, and ambient light (e.g., AHT20, capacitive ADCs)
• Enable secure OTA firmware updates and optimize power consumption for battery life
• Manage BLE provisioning workflows (e.g., BLE → Wi-Fi onboarding)
• Collaborate closely with mobile, backend, and hardware teams to ensure seamless system integration
• Write efficient, clean, and testable C/C++ code with a strong focus on stability
  
  

Required Qualifications

• 3+ years of embedded systems or firmware development experience
• Solid experience with ESP32 (ideally ESP-IDF 5.x)
• Deep understanding of MQTT protocols and low-power wireless communications
• Strong grasp of C/C++, FreeRTOS, memory management, and debugging techniques
• Experience with BLE (NimBLE preferred) and Wi-Fi coexistence
• Familiarity with sensor drivers, I2C, ADCs, and power optimization
• Experience building OTA mechanisms and handling edge cases in the field
• Comfortable working with Git and CI pipelines
  
  

Why Join Us?

• Exciting Infrastructure Challenges: part of a fast-moving team tackling exciting infrastructure and product challenges in the IoT space.
• Competitive Compensation: Transparent salary structure with performance-based bonuses.
• Professional Growth: Internal training, workshops, and external education budget.
• Flexible Work Culture: Remote and hybrid options with flexible work hours.
• Health & Wellness: Comprehensive health insurance and paid time off (20 days per year).
• Collaborative Environment: Work with top engineers and contribute to high-impact projects.
