Overview

As a Hardware Technical Lead you will play a core role in Okra’s mission. You will be responsible for designing and releasing our next generation, last mile electrification devices that ingeniously bring power to over 700,000,000 people around the globe. As an expert in this field, you will also be a mentor and coach to more junior engineers, and Okra’s lean structure means you’ll have a direct line with the Product Team - so your advice will be pivotal for product strategy and architecture definition. Okra is a global team and you will be working mostly with colleagues based in Asia during your first months, while we grow the team in the Porto office, in Portugal - you will not only play a role in growing the team but also be a key technical leader and owner of products to come!

Okra’s Hardware Products

Okra’s Hardware innovation started with the development of the Okra Pod, which was the first of its kind solar charge controller that could send/receive power to other interconnected Pods, providing numerous market and commercial benefits that established Mesh Grids one of the most viable technologies to be rolled out for remote energy access across the globe. Okra’s hardware breadth expanded to address other gaps in deploying successful Mesh Grids, including low-cost communication modules to solve issues with unreliable remote comms and battery management system (BMS) design.

The hardware team tackles challenges across a broad spectrum - innovate and tinker on new concepts in close collaboration with the product team, optimize highly critical circuits like the SMPS and current sensor designs, mature the product through certification and design for manufacturing, and push the product’s power limits, configurations (i.e. stacking systems), and reliability through increasingly stressful field usage (i.e. large motor appliances).  And across the board, the aspect of deploying these products in some of the hardest to reach parts of the world to people with the least disposable income, means a lot of creative and clever innovation to achieve both low cost and high reliability.

As Okra scales and pushes towards the 100,000 households goal, the hardware team will not only be taking the current Pod to the next level, but also expanding into batteries, inverters, and creating new products like the Hub Station which will enable entirely new topographies of the Mesh Grids to be deployed. The sky’s the limit, we’ve only just scratched the surface with where the Mesh Grid hardware can grow to.
