Polsko

• Strong proficiency in Scala and its ecosystem, or extensive experience with low-level JVM internals and high-performance Java development.
• Hands-on experience with compile-time or metaprogramming: Scala macros, compiler plugins, annotation providers in Java, or bytecode manipulation.
• Deep understanding of performance optimization
• Practical experience solving graph algorithms and concurrency challenges.
• Strong communication skills and the ability to convey complex technical concepts clearly.
• A pragmatic approach to problem-solving, balancing technical excellence with real-world constraints.
• Ability to work effectively within a team, contributing to a collaborative and high-performance engineering culture.
• Good command of English (B2/C1).

Don’t worry if you don’t meet all the requirements. What matters most is your passion and willingness to develop. Moreover, B2B does not have to be the only form of cooperation. Apply and find out!

We are #VLteam – tech enthusiasts constantly striving for growth. The team is our foundation, that’s why we care the most about the friendly atmosphere, a lot of self-development opportunities and good working conditions. Trust and autonomy are two essential qualities that drive our performance. We simply believe in the idea of ​​“measuring outcomes, not hours”. Join us & see for yourself!

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.

A few perks of being with us

• Building tech community
• Flexible hybrid work model
• Home office reimbursement
• Language lessons
• MyBenefit points
• Private healthcare
• Training Package
• Virtusity / in-house training
• And a lot more!
