About Working at envelio

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!

Your Role

As (Senior) Backend Engineer - Core Team (all genders) you will be part of an engineering squad with strong knowledge in software architecture, data modelling and graph-functionality.

How You Make an Impact

As part of the Core team, you directly influence the shape and functionality of our Digital Twin, by designing interfaces and generalized functionality for complex requirements.
You develop and extend cross-application workflows that ensure data integrity for planning and live applications. In doing so, you always strive to capture the app-specific requirements in a universally applicable solution.
You familiarize yourself with our individual and domain-specific solutions within the modelling and calculation of electrical grids and improve them in an independent and innovative way.
You are actively involved in the design and improvement of our system architecture in the area of code, data model and infrastructure.
You exchange ideas with other developers to enable a smooth interaction between the different components.

You have experience with graph-data, e.g. through experience with graph databases or other graph tooling such as networkX.
You are a team player and passionate about working with talented and inspiring people.
You prefer complex, technical challenges and have high standards for your elaborate and intelligent solutions.
You are familiar with parts of our tech stack and are looking forward to keeping up with current industry best practices.
Optionally, you are familiar with one or more of these topics: distributed computing, graph theory and geoinformatics.
You are business-fluent in English (Level C1).
