As a backend developer you will be part of the team delivering the core product of Withthegrid: an asset monitoring application for critical infrastructure. You’ll be working closely together with frontend developers, machine learning engineers, VP of engineering and the CTO to apply the latest technologies to the Withthegrid product.

This will give you the challenges and opportunities to apply your problem-solving skills whilst at the same time giving room to your creativity and ideas. All this is in a dynamic and high paced environment of a startup company. Our backend is written in TypeScript and run by NodeJS.

Data is stored in AWS S3 and AWS RDS. We take security very seriously; all data is encrypted at rest (AES256), we apply daily backups and we use TLS and DTLS encryption. We have developed an Mbed based SDK to communicate directly from IoT devices with our backend. We have open sourced this and are actively contributing to the community.

Withthegrid works on addressing one of the humanities' most significant challenges ahead: delivering a sustainable energy system. To achieve this, we need resilient and future-proof energy infrastructure. That is where Withthegrid comes in! We are building an IoT asset monitoring platform for critical energy infrastructure. We serve energy infrastructure owners such as Eneco, Stedin, Westland Infra, and NAM/Shell with our cloud-based asset monitoring platform.

IoT sensors and other customer-owned systems connect to the platform and generate asset condition data. Our application detects anomalies and improves maintenance processes through alerts with an easy-to-use UI. Our customers benefit from longer infrastructure lifetime, lower downtime, and lower costs. We are a growing company where we focus on solving our customers' challenges by using the latest technology. Our team has a hybrid structure with colleagues working remotely and others coming to our Utrecht or Amsterdam office.
