Sign up with Clera and we'll reach out the moment a role actually fits you — no more spraying applications into the void.
You will design, develop, and maintain fullstack features using React and .NET microservices while taking ownership of the end-to-end development cycle. This includes writing automated tests, managing deployments via Azure DevOps, and utilizing AI-assisted coding tools to ensure high code quality.
The role requires strong experience in React, C#, .NET, and cloud-based microservices architecture within Azure environments. Candidates must be independent self-starters with a habit of writing automated tests and possess fluent English language skills.
We are part of an international organization listed on Nasdaq Stockholm, operating in 11 countries. In Poland, we work with full autonomy. We independently choose our technologies, processes, and ways of working while maintaining the highest professional standards.
We deliver a wide range of IT projects in Poland and internationally, across multiple domains and technologies. This allows our consultants to develop their competencies and gain experience aligned with their professional ambitions.
Our collaboration is built around the CARE philosophy. For us, it means responsible project matching, transparent cooperation, and a long-term approach to professional growth.
Join us as Senior Fullstack Developer. Grow in an environment that cares about your development as much as you do.
Design, develop, and maintain fullstack features with a focus on front-end web application development using React coupled with C# and .NET microservices.
Build automated intelligent forms, dynamic UI workflows, and CMS-connected data pipelines for a greenfield project management module.
Take ownership of the end-to-end development cycle, including writing automated unit and integration tests, deployment, and monitoring.
Collaborate with the team utilizing AI-assisted coding tools like GitHub Copilot to maintain code quality and accelerate delivery.
Interact directly with Azure DevOps CI/CD pipelines and push code into a cloud-hosted Kubernetes cluster in Azure.
Experience in React, with the ability to take ownership of complex frontend tasks. Knowledge in Tailwind CSS or UI libraries like shadcn/ui is an advantage.
Experience in C# and .NET development, including practical knowledge in microservices architecture.
Experience with modern cloud deployment environments, specifically Docker and Kubernetes in Azure.
Experience working with Azure DevOps workflows, including pull requests, code reviews, and basic CI/CD execution.
