Join an early-stage mission-driven startup building a product from the ground up. We move fast so this is not for the faint of heart. You should really want to be part of building a company from scratch and at a stage in your life where working hard fits with your life. We're building solutions that are better for the planet. If you dream of a greener world, and crave more impact, responsibility, and challenge in your work, this is the team for you. We value innovation, sustainability, and a team spirit that believes in making a difference. We are looking for a senior embedded systems/firmware engineer with a proven track and direct involvement in the successful launch of at least one hardware product from scratch.
About The Role
This will start as
a project-based role with the potential to convert to full-time in the future
The ideal candidate thoroughly enjoys the field of embedded systems and controls and continues to expand their knowledge through curiosity and experimentation on and off the clock. So even if you do not have every single qualification checked off but think you have what it takes to work in a collaborative, nimble, hardware startup environment, please get in touch.

Responsibilities
- Design and develop embedded firmware for power electronic systems, including motor drives, power converters, and battery management systems.
- Develop control algorithms and implement them in real-time embedded systems.
- Perform system-level testing, debugging, and validation of embedded systems and power electronics.
- Develop and maintain documentation for firmware, hardware, and control algorithms.
- Collaborate with hardware engineers, software engineers, and power electronics engineers to ensure seamless system integration.
- Participate in design reviews and contribute to continuous improvement of development processes.
- Troubleshoot and resolve complex technical issues.
- An owner mentality; you need little to no supervision to deliver and thrive when given responsibility and latitude.
- Easy to work with and loves working with a small team, respectful, tolerant of differences
- Ability to receive and give feedback with grace and little ego
- Strong verbal and written communication skills to articulate engineering decisions and explain pros and cons to others on the team not fluent in your discipline
- Experience with EVs, HVAC, sensors, onboard computers, instrument arrays and AI-enabled hardware or similar
- Minimum 2 years of experience in embedded systems development, with a strong focus on power electronics, controls, and IoT systems
- Contributed significantly to the development and launch of at least one hardware product (or at least one board running your code)
- Working knowledge of regulations and standards
- Real love for building functional and beautiful products from scratch and hands-on experience building and prototyping,
- Proficiency in embedded Rust or C/C++ programming.
- Experience with microcontrollers (preferably ARM based), such as ARM Cortex-M, Qualcomm, TI, NXP, STM, MicrochipPIC, etc.
- Experience testing and evaluating with Dev Platforms (Raspberry Pi, Arduino PRO, Particle, NXP, etc)
- Strong understanding of power electronics principles, including PWM techniques, switching power converters, and motor control.
- Experience in developing control algorithms for power electronic systems (e.g., PID, state-space control).
- Some experience with PCB design and layout using EDA tools (e.g., Altium Designer, KiCad)
- Experience with communication protocols (e.g., CAN, SPI, I2C, UART).
- Experience with debugging and testing embedded systems using oscilloscopes, logic analyzers, and other test equipment.
- Familiarity with version control systems specifically Github
- Strong problem-solving and analytical skills
- Bachelor's or Master's degree in Electrical, Mechatronics Engineering or a related field/equivalent experience
- Experience with real-time operating systems (RTOS).
- Experience with PLCs and industrial control systems (HVAC, Process and machinery controls)
- Experience with multi-radio systems (GPS, LTE, GPRS, SAT, BLE, etc.) and AT command set.
- Experience with vehicle CANBUS systems with demonstrated work with integrating components within or external to a vehicle control system.
- Experience designing and developing embedded hardware, including PCB layout, component selection, and system integration (though we will most likely utilize dev platforms and boards initially)
- Experience with model and simulation-based design (e.g., MATLAB/Simulink).
- Experience with battery management systems (BMS).
- Experience with high-voltage and high-current power electronics.
- Strong knowledge of manufacturing processes, from prototyping to production
- Experience with functional safety standards (e.g., ISO 26262).
- Additional software skills and experience and familiarity with scripting languages (e.g., Python).
- Any experience with AI-enabled hardware
