Bucharest, Bucureşti, Romania Grid Dynamics Full time €90,000 - €120,000 per year

We are looking for a Java Developer who thrives on solving complex technical challenges and building developer tools that "just work." This project focuses on making
Bazel
, a highly capable build system, integrate seamlessly with the
IntelliJ platform
, two sophisticated systems that need to operate together smoothly for tens of thousands of developers worldwide.

We need someone who can think critically, communicate openly, and balance pragmatism with long-term vision. You should be able to question overly optimistic estimates (and explain why), propose practical solutions, and deliver results while highlighting trade-offs. Beyond contributing code, you will act as a mentor, knowledge sharer, and big-picture thinker, helping ensure the team avoids pitfalls and drives the project forward.

Responsibilities

  • Stay on top of technical developments in Bazel itself and the ecosystem, as well as within IntelliJ, and make sure our plugin is prepared.
  • Engage with language plugin and platform teams to make changes enabling better Bazel support. This includes topics like project model, source compilation and highlighting.
  • Participate in the design and implementation of important features, like making the edit-build feedback loop fast for the user in an incremental live editing environment while working with a build tool optimized for batch compilation.
  • Investigate and fixing performance bottlenecks in areas such as project sync and project model representation.
  • Work directly with customers to investigate issues arising on their codebases.
  • Pair up with other team members and review their code. Help us avoid pitfalls.
  • Be the final arbiter in all our controversial technical discussions.

Requirements

  • Proven experience working with complex systems with many moving parts.
  • Solid Java development skills with a track record of building maintainable, high-quality code.
  • Hands-on experience with Bazel, especially Bazel tooling.
  • Strong analytical and problem-solving skills, with the ability to evaluate trade-offs.
  • Excellent communication skills and willingness to share knowledge within the team.

Nice to have

  • Experience developing IntelliJ plugins or working with other IDE platforms.
  • Familiarity with Kotlin, or motivation to strengthen your Kotlin skills.
  • Experience optimizing performance in large build systems or IDE tooling.
  • Previous mentorship or leadership experience.

We offer

  • Work on bleeding-edge projects on a team of experienced engineers
  • Flexible working hours
  • Specialization courses
  • 24 days annual leave + an additional of 5 sick days
  • Floating Holidays
  • Private medical subscription for employees and their family members
  • Benefits basket with the total value of 650 euro/year
