Firmware Engineer

About Nunam:

Nunam is set on a journey to research and build solutions for Electric Vehicles (EVs) to extend their battery’s life. At the end of life of these EV batteries we are developing the technology to repurpose them for a second life application. We build energy storage solutions(ESS) with used batteries and battery data analytics products using state of the art techniques from battery modelling, data science, machine learning and embedded hardware. This goal is achievable with an outstanding team, and therefore we are looking for energetic and passionate candidates who care to create a sustainable world.

Are you someone who

1. Is an enthusiastic and experienced embedded firmware engineer who can join us in our journey to develop a battery management framework and IoT stack?
2. Is up for a challenging job with a good learning curve? You will fit right in our fast-paced start-up environment and a multidisciplinary team.
3. Cares about sustainability? You’ll be working at the cross section of two booming markets - Electric Vehicles (EVs) and sustainable energy storage with renewable energy sources.
4. Looking for impact with your work? You code will enhance the energy delivered and life of Lithium batteries, bringing direct benefit to users as well as propelling forward the green revolution.
5. Values freedom and autonomy to take ownership and responsibility of problems being tackled? You’ll fit right in with us.
6. Is ready to change their stance when new data points are encountered? We offer a culture where everyone has a voice to present data-backed opinions for any decisions taken.
7. Wants a great team and work environment? Ours is a fun, open, friendly, inclusive and respectful culture.

What you would be responsible for:

1. Scaling up of a IoT firmware stack that would run on 10,000+ devices in various states of deployment and firmware version
2. Architect and develop the battery management framework in collaboration with battery modelling team for constrained microcontrollers
3. Developing automated test suites for manufacturing
4. Using continuous integration to automate builds and identify issues quickly
5. Building the testing framework for working with test-driven development (TDD)
6. Working with Zephyr OS for building a scalable and modular code base for multiple products
7. Low power optimizations
8. Deploying Machine Learning (ML) models for microcontrollers
9. Having fun with the team while having a positive impact on the world :)

Technical skills you can offer:

1. Experience in developing firmware for at least one product lifecycle
2. Experience with project planning with leadership skills in a team of developers
