Profile match
Link Group is a Polish technology services company founded in Warsaw in 2016 that builds and supplies engineering teams to clients across Europe. Its model combines body leasing and managed teams with delivery of complete software, cloud and cybersecurity projects, drawing on a large bench of contractors rather than a fixed permanent staff. The company works heavily in financial services, telecommunications and public sector projects, and has built a specialisation in blockchain and distributed ledger engineering alongside more conventional cloud and application development work.

We are looking for a Mid/Senior Full Stack Engineer to join a product engineering team working on cloud-based applications built with React, Node.js, Java Spring Boot, and Azure. The role is hands-on and focused on designing, developing, and improving scalable web applications, APIs, and microservices in a modern distributed environment.

You will work across frontend and backend, contribute to technical decisions, support code quality, and collaborate closely with engineers, product teams, and architects. This is a good fit for someone who enjoys building features end to end, understands modern engineering practices, and wants to grow further in architecture, cloud, and platform-level topics.

Key responsibilities

  • Develop and maintain web applications using React, TypeScript, and modern frontend tooling.
  • Build and improve backend services and APIs using Node.js and Java Spring Boot.
  • Work with microservices and integration patterns in a cloud-based environment.
  • Participate in solution design, technical refinements, code reviews, and architecture discussions.
  • Support the development of scalable, secure, and reliable applications.
  • Improve code quality, maintainability, performance, and test coverage.
  • Collaborate with product owners, architects, and other engineers to translate business needs into technical solutions.
  • Support CI/CD and deployment processes in Azure.
  • Use AI-assisted development tools such as GitHub Copilot to improve productivity and code quality.

Requirements

  • Commercial experience as a Full Stack Engineer or Software Engineer working across frontend and backend.
  • Strong knowledge of JavaScript/TypeScript, HTML5, CSS3, and modern frontend development.
  • Good hands-on experience with React.js.
  • Experience with Node.js and frameworks such as Fastify or Express.
  • Experience with Java Spring Boot for building REST APIs and microservices.
  • Understanding of distributed systems, REST API design, and integration patterns.
  • Experience with cloud-based environments, preferably Azure.
  • Knowledge of relational databases such as PostgreSQL or MS SQL Server.
  • Familiarity with CI/CD pipelines, version control, and modern software delivery practices.
  • Good communication skills and ability to work effectively in a team.
  • Practical experience or openness to working with AI-assisted engineering tools such as GitHub Copilot.
  • Nice to have
  • Experience with microfrontends or large-scale frontend architecture.
  • Knowledge of Azure App Services, Azure Functions, or Azure DevOps.
  • Experience with DevOps practices, CI/CD, and automated testing.
  • Experience with performance optimisation and troubleshooting distributed applications.
  • Familiarity with cloud security, scalability, and reliability practices.
  • Experience mentoring less experienced developers or supporting technical decision-making in a team.

Who we are looking for

We are looking for an engineer who can deliver high-quality software, work across the full stack, and take ownership of assigned technical areas. You will be a strong fit if you enjoy practical development, understand both frontend and backend perspectives, and want to grow in a modern cloud-based product environment.
