Overview

As Senior Embedded Systems Engineer, you will play a crucial role in developing and implementing the code to run our cutting-edge energy storage equipped appliances. Your primary focus will be device connectivity, data flow via cloud pipeline, and firmware fleet management scaling, but you’ll have ample opportunity to work on projects that include oven and stovetop performance improvements, battery management, power electronics, graphics design, and new product development. You will work with a small, cross-functional team of skilled, passionate engineers to design, implement, and test new features and the occasional recipe.

We value a diverse workplace and are assembling our team to match these values at this early stage. We especially welcome different backgrounds, experiences, abilities, and perspectives, and strongly encourage people of all ethnic backgrounds and genders to apply.

This is a full-time position and it is expected to be in-office 4 days per week with 1 day flexible for in-office or remote work. Our office is located in Berkeley, CA.

What You'll Do

• Develop, enhance, and maintain firmware for the Charlie induction range.
• Interface with hardware design and development teams to ensure smooth integration of software and hardware components.
• Implement and test new features (note: this often means cooking food).
• Identify bugs and implement robust solutions (note: this also often means cooking food).
• Maintain comprehensive documentation of code, software architecture, and user manuals to ensure smooth transitions and updates.
• Understand and improve the network stack and connectivity capability of our microcontrollers – areas of improvement are failure mechanism detection and recovery for OTA updates and wifi/application layer protocol disconnects, fleet telemetry database management, remote unit control, and bluetooth provisioning application flow.
• Develop knowledge of the general codebase to implement new features, triage bugs, and collaborate with other firmware developers to support product development.
• Support the manufacturing test process for the firmware team with ability to interface and make modifications to firmware flashing station, provisioning station, and end-of-line testers.

What You'll Bring

• Experience debugging and implementing network protocols.
• Significant experience with WiFi, Bluetooth, TCP/IP, and application layer protocols such as CoAP, HTTPS, MQTT, or other.
• Experience with over the air programming and/or bootloader development
• Experience with database management and REST API design/use
• Ability to write portable, lightweight, thread-safe code that accounts for and responds to potential failure modes.
• Deep knowledge of C programming for embedded systems. Cpp experience is helpful.
• Proficiency using FreeRTOS based applications.
• Familiarity with ESP-IDF (ESP-32 development framework), CMake, or ability to pick up new libraries and processor families quickly.
• Comfortable working with version control and project management tools (e.g. issue tracking).
• Testing code with hardware (e.g. revision and unit testing).
• Comfortable generating documentation for code and hardware.
• Bachelor’s degree in engineering, physics, or a related field is preferable but not a strict requirement.
• 5+ years of industry firmware engineering experience with relevant experience in embedded implementations of networking stacks.
