Software Engineer – Internal Tools & Automation (m/f/d)

As a Software Engineer, do you want to work on solutions with Python, APIs, and automation that are used directly in daily operations? In this role, you will develop internal tools, services, and interfaces, translate requirements from business departments into pragmatic technical solutions, and meaningfully connect existing systems. You will work with modern web technologies, databases, and API-based integrations, and develop your solutions step-by-step from initial prototypes and MVPs into stable, maintainable applications.

• You will further develop new and existing internal applications and services with Python and technically implement specific requirements from our operational business.
• You will work together with our business departments to understand and structure business requirements, and to develop pragmatic technical solution approaches, prototypes, and MVPs from them.
• Together with the team, you will identify potential for automation and optimization and connect existing systems via APIs, databases, and interfaces.
• You will further develop functional prototypes into stable and maintainable solutions, and receive support and sparring on architectural questions as well as integration into central systems from our technical team and the Core Platform Team.
• You will ensure the quality of your solutions with clean and testable code, automated tests, and understandable technical documentation, and use modern AI tools where they meaningfully support your work.

• You already have practical experience in software development and have independently worked on applications, tools, or automation. You already have good knowledge of Python and/or JavaScript or TypeScript.
• You have a good basic understanding of APIs, databases, and fundamental software architectures, and have already worked with Git and collaborative development processes.
• You know the basics of clean, maintainable, and testable code and ideally have already had initial contact with CI/CD, automated tests, or Docker. You don't need to be a professional in this yet.
• You like to think beyond pure technical implementation, are interested in the business context, and are eager to further develop requirements together with technical and non-technical stakeholders. At the same time, you are curious, eager to learn, and open to feedback.
• You already use AI tools like ChatGPT, Claude, Cursor, or comparable applications in your daily development workflow or want to engage more with them and learn to use them meaningfully and responsibly.
• You have at least B2-level German language skills for collaboration with our business departments, as well as at least B2-level English language skills for technical documentation, tools, and code.

• #HybridFlex: Adapt your working hours to your productivity and work flexibly from home or our central offices with our hybrid work model. We give you the space you need.
• #YourTech2Shine: Mac or Windows? You decide. We'll provide you with the appropriate home office equipment for maximum productivity.
• #StrongYouHealthyUs: From JobRad and Hansefit membership to (online) health days and on-site physiotherapy massages, ergonomically equipped offices, company doctor, confidant, and extensive company health management – we actively promote your health and well-being.
• #Balance: 30 days of vacation, time tracking with overtime compensation – of course. With numerous sports equipment in the office, fitness and coffee breaks, or even corporate benefits for more shopping fun, we offer approaches for regenerative breaks. Time is an investment. In you and in us.
• #DesignOpportunities: Depending on your interests and strengths, you can contribute your expertise to exciting projects and help shape our growth and success together with WattFox.
• #ArriveAndGetStarted: We value structured onboarding. Therefore, we give you everything you need, both culturally and professionally, to develop in the best possible way.
