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.

Role Purpose

We are seeking an elite, highly skilled Senior Java Full-Stack Specialist to join our dedicated technical t eam. In this hands-on Subject Matter Expert (SME) role, you will act as a high-impact problem solver deployed across enterprise programs to diagnose, troubleshoot, and resolve critical technical bottlenecks, system defects, and architectural challenges.

This position focuses purely on technical mastery, code-level execution, and cross-team problem resolution-without administrative people-management responsibilities.

Key Responsibilities

  • High-Priority Incident & Problem Resolution: Serve as a core technical expert within the SWAT unit, diagnosing and resolving high-severity technical issues, integration blockers, and operational bugs across complex enterprise systems.
  • Hands-on Full-Stack Engineering: Write, refactor, and review clean, maintainable code across modern Java backends and modern JavaScript frontend frameworks (Angular/React).
  • System Modernization & Architecture: Support architectural discussions, microservices design, and continuous system modernization efforts across core enterprise platforms.
  • Proactive Risk Mitigation: Analyze system performance, dependencies, and code pipelines to identify potential bottlenecks and vulnerabilities before they impact production.
  • Cross-Team Collaboration: Partner with cross-functional development squads, architects, and DevOps engineers to streamline delivery and align technical integrations.
  • AI-Assisted SDLC Optimization: Leverage cutting-edge AI coding tools, copilot extensions, and automated frameworks to accelerate software delivery, debugging, and testing.

Qualifications & Technical Requirements

Core Requirements:

  • 10+ years of hands-on commercial experience engineering web-based applications across Java backends and modern frontends.
  • Core Backend Stack: Advanced proficiency in Java (Java 17/21/25), Spring Boot, and microservices architectures.
  • Frontend Expertise: Solid practical experience with Angular or React.js (proficiency in both is strongly preferred).
  • APIs & Integration: Extensive background in building and consuming REST APIs and legacy SOAP web services.
  • Database Management: Strong proficiency in SQL and relational database systems (MS SQL Server preferred).
  • Cloud & DevOps: Practical experience with Microsoft Azure (Azure DevOps, Cosmos DB, Application Insights) and modern CI/CD deployment pipelines (GitHub, Git).
  • AI Tooling: Demonstrated experience applying AI-driven tools and agentic practices within the Software Development Life Cycle (SDLC).
  • Education & Languages: Bachelor’s degree in Computer Science, IT, Engineering, or a related technical discipline. Fluent business English (spoken and written).

Nice-to-Have Skills:

  • Hands-on experience with Guidewire core platforms.
  • Message broker experience using Apache Kafka or RabbitMQ.
  • Exposure to Jutro Digital Platform (JDP) or similar enterprise frontend frameworks.
  • Official certifications in Java, Spring, SQL, or Azure Cloud.
