The IoT Engineer is responsible for the design, development and testing of the edge device and data hub. This includes the hardware like the sensors, controllers, logic circuits, and the LoRa / GSM senders. 

Key areas of responsibilities: 

  1. Develop the edge devices to gather data via sensors

  2. Design the electronics circuit to interact with the controller in the edge device

  3. Maintain the network of a large number of sensors in a wireless sensor network

1. Develop the edge devices to gather data via sensors.

  • Participate in the design, development, and testing of the hardware on a daily basis

  • Understand the limitations, pros and cons of different sensors and measuring methods

Working at
Wattero

Wattero is developing peer-to-peer energy solutions for those that lack access to electricity. Together with our local partners, we identify the areas without connection to the power grid and offer affordable and high-quality solar solutions with flexible payment plans and a market system where customers can sell their surplus power to their neighbors via mobile. The co-founders of Wattero are two Norwegian recent graduates from NTNU and the University of Oslo interested in social issues and travel. We started Wattero because there is energy poverty in the world and we see the possibilities in ending this. Also, starting a business is cool! In addition to the co-founders, we also have Patricia from Brazil who is responsible for Marketing and Kjersti from Norway who is in charge of Business Development. We are currently expanding our team and we hope to find both a talented CTO and CFO. We are looking for ambitious students or graduates who are motivated to learn new things, are independent, and want to work with microgrid in areas without power. We work hard during the day like to change up the working environment and happily have an after-work beer together.
