Firmware Developer – Summer 2021 Co-Op


GBatteries was founded six years ago to tackle one of the world’s most pressing issues: the transition to a cleaner future through electrification. We are pioneering battery technology which enables ultra-fast charging of Li-ion batteries without compromising battery life — and without changing the battery’s chemistry or manufacturing process.​ Ultimately, our mission is to accelerate the mass adoption of electric vehicles.

We are working on some of the biggest challenges in energy storage, and are looking for the right people to join us as we develop our technology and continue to scale.

As a Firmware Developer, you will be working in a fast-moving team of engineers and scientists to develop implementation design solutions for an active battery management system. You’ll be involved in developing production-quality code that’ll be implemented into products used by customers. Tasks include designing and programming of embedded software implemented on microcontrollers and SoCs. You’ll be also generating and maintaining documentation for testing, manufacturing, and product specification.

You’ll join a small but growing software team where everyone—including our interns—is striving to constantly improve their knowledge of infrastructure, systems, and cares about creating dependable products. While we are still growing and have plenty to do, we are incredibility supportive of each other and pitch in to support our peers when problems arise.


  • Computer science, electrical engineering or related background
  • Previous experience in at least 1 firmware development role in industry 

Must haves:

  • Programming, integration and debugging experience in C/C++
  • Experience in testing and validating firmware functionality directly on embedded platforms
  • Understanding of communication protocols: I2C, UART, SPI, TCP/IP, USB
  • Understanding of memory mapping and interface, concurrency, and hardware- software interface
  • Hands-on experience with test equipment,including in-circuit debuggers, signal generators and oscilloscopes

Nice to haves:

  • Programming, integration and debugging experience in Assembler
  • Hands-on experience with low-level/embedded TCP/IP stacks
  • Hands-on firmware experience with TI’s C2000 family of microcontrollers
  • Hands-on with scripting using languages such as Python
  • Hands-on soldering skills
  • Experience in implementing firmware/software elements on microcontrollers and SoCs, in both bare-metal and RTOS-based environments


  • Become familiar with the firmware architecture used in our in-house research systems
  • Start working on a primary design project that will evolve over the course of the internship



  • Assist  the embedded team with developing firmware elements and testing new features on the systems
  • Start to better understand the role of the firmware features within the R&D environment at GBatteries
  • Make significant progress on your primary design project for the term



  • Wrap up your primary design project
  • Become a reference for the inner workings of certain aspects of the firmware
  • Educate the rest of the team with the findings and improvements you made over the course of your internship


  • Autonomy: There's no red tape on what technology frameworks you can use, or what language you should be coding in. We believe in using the best tool(s) for the job, and learning any new ones along the way.
  • Scope: You won't be adding small features to a monolithic code base; you will be building entire products from start to finish. Your team members will recognize you for the products you build     and the impact these products have on their workflow. You will have the     opportunity to identify the business needs for a particular product, work through the development life cycle, and interact with your customers directly.
  • Interesting Problems: Much of what we do is in uncharted territories. As a result, we are often posed with interesting and challenging engineering problems, which will encourage you to     prototype, iterate, and innovate. It's part of the company culture to encourage crazy ideas, and celebrate failures as learning opportunities. Many of the design problems you will encounter won't have answers on Google or Stack Overflow, they will encourage you to come up with unique     approaches and strengthen your design thinking.
  • Growth: Working at a start-up is a great way to supercharge your skillset, and accelerate your learning. You will be put in a fast-paced environment where you're always working at the bleeding edge of technology.


We are working on many exciting projects towards our ultimate goal of breaking down the final barrier preventing the adoption of electric vehicles; range anxiety. We’re a growing company working with some of the largest manufacturers in the world, and there’s still a huge amount to do. Even as an intern joining us, you’ll be able to see the impact of your work from day one and have the opportunity to see the final effect on real world products. We encourage unconventional thinking, and seek resilient problem solvers who aren’t afraid to get their hands dirty.

 During the pandemic,we are operating remote-by-default.



We've not set it in stone, however our preferred salary range for this position is $17-26 per hour, depending on experience and background.


Is the idea of enabling the global mass adoption of electric vehicles exciting to you? We’d love to hear from you!
