You will work on business-critical applications, combining maintenance and modernization of existing systems with the development of new solutions. The role is backend-leaning, but you are comfortable working across the full stack-from .NET APIs to React frontends and deployment pipelines.
You enjoy solving complex problems, working independently, and taking ownership. You think beyond implementation: how systems evolve, scale, and deliver long-term value.
At DEME, we are actively adopting AI-augmented engineering practices. You will help shape this transition by integrating tools such as GitHub Copilot, Claude, Kimi or similar agents into daily workflows-using them to accelerate development, improve quality, and rethink how software is delivered.
