What we expect

• Write high-performance Scala code with a strong focus on runtime efficiency and memory management
• Work confidently with JVM internals, Java (21+), and low-level system behavior
• Apply compile-time or metaprogramming techniques such as macros, compiler plugins, or bytecode manipulation
• Tackle complex problems in concurrency and graph algorithms with practical, scalable solutions
• Optimize performance through careful trade-off analysis across compilation and execution layers
• Communicate technical ideas clearly within a distributed team environment
• Collaborate effectively with peers to maintain a high standard of engineering quality

Nice to have

• Experience with C++ for performance-critical components
• Familiarity with annotation processors or advanced Java tooling

VirtusLab is a leading European software consulting and engineering company, home to over 350 EU-based professionals.

Project Scope

The project builds a high-performance framework in Scala focused on object and graph-oriented computing. It integrates deeply with JVM internals and the Scala compiler to solve complex challenges in concurrency, memory allocation, and graph processing. Designed for scalability and efficiency, the framework supports over 1000 engineers globally.

Tech Stack

Scala 2.13, JVM, Java (21 with planned migration to 25), C++, performance optimisation and testing

Team

The team consists of over 10 experienced engineers distributed across North America, Europe, and Asia. They bring deep expertise in Scala, JVM internals, and performance optimization, working closely under a UK-based Project Manager.
