We're seeking a Senior Firmware Engineer to design, develop, and implement low-level firmware for our next-generation connected product. You'll work closely with cloud services, mobile app, product and hardware teams to integrate Wi-Fi, Bluetooth, and other connectivity features seamlessly, while actively collaborating and contributing as a key team player.

Key Responsibilities

• Design and implement robust firmware on MCU platforms, ensuring support for wireless connectivity, data upload, OTA updates, sensor integration, and other core functionalities.
• Develop and optimize communication stacks for Wi-Fi, Bluetooth, and other wireless protocols, ensuring reliable pairing, network configuration, and data exchange.
• Write efficient low-level code that integrates with hardware peripherals (e.g., RF modules, sensors) using standard interfaces such as GPIO, I2C, SPI, and UART.
• Apply best practices for error handling and performance optimization to support robust connectivity features.
• Work closely with cross-functional teams to rigorously debug, test, and troubleshoot firmware, ensuring optimal performance, reliability, and security.
• Engage actively with multidisciplinary teams, sharing insights and aligning on system-level requirements to drive cohesive project success.
• Contribute to the deployment readiness of our systems for large-scale production.
• Evaluate code from peers to maintain best practices in style, accuracy, and efficiency.

Required Qualifications

• Bachelor’s degree in Computer Science, Electrical Engineering, or equivalent experience, with 5+ years in embedded systems development.
• Deep understanding of computer networking and firmware for data-intensive applications.
• Strong expertise in C programming for embedded systems, with a solid grasp of memory management and real-time operating system principles.
• Hands-on experience with connectivity modules (Wi-Fi, Bluetooth) and RTOS (FreeRTOS preferred).
• Proficiency in hardware-software interfacing, including protocols like GPIO, I2C, SPI, and JTAG.
• Proficiency with troubleshooting tools (debuggers, Wireshark) and measurement equipment (multimeters, oscilloscopes, logic analyzers).
• Demonstrated expertise in debugging and rigorous testing to quickly identify and resolve complex issues.
• Familiarity with version control, CI, and build systems.

Preferred Skills

• Experience with ESP32 microcontrollers.
• Working knowledge of cloud computing protocols (e.g., MQTT) and platforms like AWS (AWS CDK is a plus).
• Experience with cellular connectivity.
• Excellent communication and interpersonal skills to foster a collaborative, team-oriented environment.

The estimated base salary range for this position is $180k to $225k, which does not include the value of benefits or a potential equity grant.
