  • Design, develop, and maintain microservices, APIs, and integration layers

  • Ensure code quality through unit tests and architectural consistency

  • Plan and realistically deliver roadmap items, focusing on feasibility, prioritization, and execution

Requirements

  • Minimum 7 years of commercial experience in .NET development, including senior or tech lead responsibilities

  • Strong backend expertise combined with hands-on experience as a Fullstack Developer (Angular)

  • Solid understanding of cloud-native architectures and modern backend systems

  • Solid understanding of Domain Driven Design, Clean Architecture, microservices, and API design

  • Practical experience using AI tools in daily development work (e.g., AI copilots, AI-assisted coding, AI-driven workflows)

  • Pragmatic, realistic engineering mindset focused on delivery, planning, and rational decision-making

  • Ability to take ownership of complex topics and drive them to completion

  • Fluency in English

  • Residing in Poland required
