About The Role
We are seeking a passionate Software Developer (m/w/d) for electrical network calculation and optimization to join our dynamic team. In this role, you will play a pivotal part in shaping the future of energy supply by developing cutting-edge software solutions that automate, calculate, and optimize power grids. Your work will form the foundation for the smart grids of tomorrow, contributing actively to the energy transition through innovative technical solutions in both national and international projects. You will collaborate closely with network experts to translate requirements into high-performance algorithms, working within a creative environment that values innovation and responsibility. This position offers an excellent opportunity to influence the energy landscape, take on meaningful responsibilities, and grow your expertise in a forward-thinking company.
Qualifications
The ideal candidate holds a completed degree in electrical engineering, computer science, or a comparable qualification from a university, technical college, or university of applied sciences. You possess strong proficiency in C++ programming and a solid understanding of modern software architecture principles. Experience in network calculation, including the application and implementation of relevant methods, is essential. Familiarity with software craftsmanship practices such as unit and integration testing, clean architecture, and design patterns is required. You should demonstrate a high willingness to learn and develop both technically and personally. Analytical thinking is crucial for tackling complex problems methodically, and you should be comfortable working collaboratively in a team environment, open to feedback. Additionally, you have substantial experience with distributed systems, data models, and cloud environments, preferably within the energy or control system sectors, including critical infrastructure (KRITIS).
Responsibilities
As a Software Developer in our team, your core responsibilities will include designing and implementing software solutions that automate and optimize electrical power networks. You will develop algorithms and tools that support network calculation and energy trading, ensuring high performance and reliability. Collaborating with network experts, you will transform technical requirements into effective, scalable solutions. Your role involves actively participating in the entire development lifecycle, from conception through testing and deployment, always adhering to best practices in software engineering. You will contribute to innovative projects that support the energy transition, helping shape the future of sustainable energy systems. Responsibility for maintaining high-quality code, documentation, and continuous improvement of existing systems will be integral to your daily work. Furthermore, you will stay abreast of emerging trends and technologies relevant to distributed systems, cloud computing, and energy management to ensure our solutions remain at the forefront of innovation.
Benefits
We offer a stimulating work environment characterized by a committed, competent, and friendly team, with flat hierarchies and short decision-making channels. You will have the flexibility to choose between a subsidy for public transportation or a JobRad bike to support environmentally conscious mobility. Our flexible working arrangements include up to three mobile workdays per week and flexible working hours (Gleitzeit), enabling a better work-life balance. Employees enjoy attractive discounts through our corporate benefits platform, along with opportunities for professional growth through regular feedback sessions and personalized training programs. We foster a team-oriented culture with shared events and open communication, encouraging a collaborative and supportive atmosphere. Joining our company means being part of pioneering projects that contribute to a smarter, more sustainable world.
