Key Responsibilities:

  • Develop and maintain Java-based applications and plugins for Atlassian Data Center
  • Ensure compatibility of Atlassian DC Marketplace plugins across platform releases, including legacy and new versions

  • Apply best practices in Java development, including clean code, testing, and code reviews
  • Participate in system design discussions, proposing and implementing architectural improvements
  • Work closely with cross-functional teams to deliver reliable, high-quality solutions

Requirements:

  • 3+ years of professional experience in Java development
  • Working proficiency with React, JavaScript, and TypeScript (full-stack experience is a big plus)
  • Experience across the full SDLC: design, implementation, release, and support
  • Strong understanding of system design and architecture (scalability, concurrency, load balancing)
  • Knowledge of security best practices (XSS, CSRF, SQL Injection) and auth models (JWT, OAuth 2.0)
  • Solid experience with SQL databases (indexes, query optimization, ACID, isolation levels) and familiarity with NoSQL concepts
  • Experience with the Spring framework
  • Nice to have: familiarity with Apache Velocity and/or Atlassian DC plugin development
  • Good communication skills and ability to work effectively in a collaborative team environment
  • Proactive, responsible, and willing to learn new tools and technologies

What We Offer:

  • Competitive salary and performance-based bonuses
  • Opportunities to grow in the Atlassian ecosystem and work on global-scale solutions
  • Career development, training, and support in obtaining relevant certifications
  • Friendly, professional team and a culture based on trust and collaboration
