Joining our existing Sheffield-based team, you will be working with other Embedded Software Engineers to match our ambition to radically reimagine transport and energy in Africa.

You’ll be working across a range of disciplines to bring our solutions for energy access to market, including the replacement of petrol generators with swappable batteries and replacing petrol motorbikes with our own electric motorbikes, using the same battery swap system. It’s an exciting and varied challenge.

We’re looking for a senior candidate to join our team to add capacity for our existing projects and to help steer the direction of our product development.

The role will interest you if:

You’re excited by the prospect of transforming the off-grid energy and e-mobility market in Africa.
You have a passion for improving the lives of the customers who use our products.
You are interested in working in a truly full-stack team. You will be working closely with hardware engineers, product designers and other stakeholders at our tech hub in Sheffield.

On a given day, you’ll likely…

Work collaboratively with other disciplines across the company to continuously refine and improve our understanding of how our products can create the greatest impact, get to market quickly, and operate reliably for our customers.
Test ideas and designs: back-of-the envelope calculations, building simulations and designing validation tests.
Design and test firmware that runs in our intelligent batteries: BMS controls, system-level behaviours and optimization, system diagnostics and updates, RF communication protocols and control algorithms.

We would like to hear from you if you have experience in the following areas:

Excellent knowledge of C language.
Experience with ESP32 microcontrollers.
Knowledge of hardware communication protocols: SPI, UART, I2C, CAN.
CI and/or unit testing for firmware.
Experience with Git version control system.
Strong debugging skills.
Use of logic analysers, scopes etc. to debug communications or firmware issues.

Any of the following would be a strong plus:

Knowledge of network protocols, such as TCP, UDP, TLS, HTTP.
Knowledge of Bluetooth LE, GAP, GATT.
Familiar with low-level aspects of RTOS.
Custom bootloaders.

Don’t worry if you don’t meet all of the above requirements. Send us a CV and we can have a chat.
