About The Job
Your Mission
Industry resources like energy or water are becoming increasingly scarce on our planet. Sensorfact’s mission is to eliminate industrial energy waste and help businesses operate more efficiently. We make energy saving easy through a plug-and-play Energy Management System that combines wireless sensors, a user-friendly online platform, and smart algorithms to detect savings opportunities. By doing so, we help our customers cut waste—energy, water, gas, and more—by 5–10%.
We're a purpose-driven team that believes everything starts with 'why'. We value ownership, meaning everyone is invested in the bigger picture and the real-world impact of their work. Our collaborative culture encourages open feedback, continuous experimentation, and smart development practices. Whether you're working with stakeholders to shape solutions or crafting intuitive interfaces, you're part of a shared mission to build a more sustainable future.
Technologies you will be working with
Our core platform is based on a microservices architecture using Node.js as the runtime environment platform. These microservices are deployed in Kubernetes (AWS is our cloud infrastructure provider). Every new service is coded using TypeScript (as usual, there is always a legacy part). Our back-end architecture follows a real-time design principle for which we use Kafka as a core component.
The front-end side of our products is built with React. We use a mix of Redux and Apollo Client for the store and rely on GraphQL for data fetching. The UI is built around Material UI. Data viz is handled by a few custom components and Apex Charts. Finally, testing is done with Jest and Cypress.
Our source code is on GitLab, and we use GitLab and ArgoCD for CI/CD purposes. Prometheus and Grafana are our main monitoring tools.
You do not need to be an expert in every technology mentioned here, but transparency is another of our values, so we want you to know what you are applying for.
