Too easy is boring! Together, we are on a mission to drive forward the energy transition. We love what we do, and we are unafraid to dive in. We believe in taking ownership of our work and in continuously growing and evolving. In short: own it, love it, grow with it.
We are a humble team of coffee and maté lovers with over 20 nationalities. With our geek humor, our love for emojis and random facts is only natural. Over 150 envelians are already on board. Dive in and thrive!
As Senior Expert - Energy Grid Solver & Calculations (all genders) you will be part of an engineering squad with strong knowledge of electrical engineering, coding, databases, and software architecture. Together, you drive the topics surrounding electrical power system engineering and electrical/mathematical models and algorithms, have an impact on the experience of our users, our organization, and our engineering practices. A particular focus lies on models and calculation methods/mathematical solver for asymmetric grid structures and related components.
-
You are part of a cross-functional department and team (backend, frontend, DevOps developers, design and product manager) and develop state of the art electrical engineering related applications which bring effective customer value
-
You design, enhance and implement electrical engineering workflows and mathematical solvers in accordance with the current state of technology and best practices

Intelligent grids for a sustainable future worldwide — this is our vision! Therefore, we are building the digital hub for the future of power grid management: The Intelligent Grid Platform (IGP). The IGP is the core of our software as a service solution. It’s our ambition to make the IGP and envelio 1 % better everyday. Grow with us!
As a remote-first company, we let you decide how much you want to work remotely – from 0% to 100%. Whether you live in Cologne or Aachen, Bonn or Berlin, Munich or Castrop-Rauxel; all you need is internet! You can also work from abroad for up to three months per year. Since 2017, we have built a diverse international team, with English as our company language.
