About Working at envelioToo 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 thriveYour Role 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.How You Make an ImpactYou 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 valueYou design, enhance and implement electrical engineering workflows and mathematical solvers in accordance with the current state of technology and best practicesYou are part of the conceptualizing and developing of professional backend solutions to continuously evolve our product in an agile working environment together with the other cross-functional squads in the engineering departmentYour ProfilePerfection is a myth We’re more interested in the human behind the screen, so think of these criteria as helpful directions — we're excited to see how your unique skills might fit in.You have a background in electrical engineering, with a profound knowledge of the electrical distribution system and its structure and equipment modeling (e.g. conductor modeling including couplings, transformer modeling with internal wiring and core effects, earthing concepts & equipment. Experience with asymmetric elements like center-tapped/split-phase transformers and transformer banks is a plus.You have profound knowledge about and experience with the implementation of calculation methods for grid calculations (multiple power flow formulations symmetric and multiphase,  short-circuit/fault calculations). Ideally, you are knowledgeable about state estimation and general optimization problems.You have profound (practical) experience in programming - 5 years or more - in the context of electrical engineering and mathematical algorithms (Python, ideally also C++, Go or Rust), software design and architecture principles in context of large-scale software projects.You are eager and passionate about writing state of the art software as major part of your daily workYou are a team player and passionate about working with talented and inspiring peopleYou are looking for technical challenges and pride yourself in finding smart and creative solutionsYou are business-fluent in English (Level C1)Ideally you are familiar with parts of our tech stack, with current software design principles and are looking forward to keeping up with current industry best practicesHow we develop SoftwareAgile working method with Kanban in cooperation of all squadsContinuous integration / Continuous deliveryClean (and simple) code, documentationHigh unit test coverage and regular code reviewsKnowledge sharing sessions between developers“You Code it – You Own it” – Team responsibility for certain functional areas of the productOur Tech StackPython, incl. additional frameworks, Pytest and Celery Modern C++20 for computationally intensive tasks PostgreSQL RabbitMQ, Redis Docker, Kubernetes Your BenefitsJoin us fully remote or at our lovely office in Cologne in a hybrid working modeOption for remote work from abroad (up to three months per year)  State of the art technology and modern tech stack Excellent hardware equipment (16 inch MacBooks, 2 screens at your workplace) 30 holidays + 3 corporate holidays  Support for your health through sports membership cooperations  Flexible use of a monthly mobility budget (e.g. Jobrad, public transport) Time and resources for individual growth  envelio pension plan  Regular company and team events About usIntelligent 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.
