What you`ll do: * Develop, maintain, and enhance Windows-based desktop applications using .Net. * Maintain and develop DLLs written in C++. * Implement CI/CD pipelines for development and QA processes. * Act as a liaison between the customer and the development team, collecting and synthesizing feedback into actionable tasks. * Ensure on-time delivery of high-quality products. * Collaborate with cross-functional teams, including engineering, sales, marketing, and support, to deliver successful projects. * Identify potential risks and issues within the project and propose mitigation strategies.
What we offer: * Meaningful Impact: Build solutions that are used every day by thousands of businesses — your work will directly improve real-world security and connected device experiences. * Product & Process Ownership: Help shape not only the product, but also how we build and deliver it — your ideas and decisions will have visible impact. * Industry Influence: Contribute to key security standards and best practices, staying ahead of the curve in a fast-evolving industry. * Modern Tech Stack & Hardware: Work with the latest hardware and the tools you need to do your best work. * Time Off & Flexibility: Vacation days, paid sick leave, and public holidays in line with German legislation — plus flexibility built around outcomes, not micromanagement. * Learning & Development Budget: We support continuous growth by covering hard and soft skills courses, trainings, and access to e-learning platforms. * Coworking Support: Prefer not to work from home every day? We offer coworking compensation so you can choose the environment that fits you best. * Language Learning Support: Monthly fixed compensation you can use to improve your English or German through the learning format of your choice. * Strong Team Culture: Open collaboration, a flat structure, and thoughtful onboarding—your voice is heard, and you can make an impact from day one.
