Scala Engineer (Expert) @ VirtusLab

What we expect in general

• 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!

About the role

Project
Graph

Project Scope
We are building a cutting-edge, high-performance object- and graph-oriented framework in Scala. This involves deep integration with the JVM internals, Scala compiler, and advanced graph work. The work requires focus on performance, with an emphasis on JVM memory allocation, concurrency, and trade-off analysis at every level.

Tech Stack
Scala, JVM, Java (21, with migration to 25 planned for this year), C++, performance optimisation and testing.

Challenges
Extending and pushing the limits of Scala and JVM to create a high-efficiency framework, used by 1000+ engineers worldwide.
Solving complex concurrent computing, graph processing, and compiler-related problems.
Optimizing performance at both the runtime and compilation level Close collaboration with internal tooling teams.

Team
10+ engineers, distributed across North America, Europe, and Asia. Direct Project Manager is from the UK.
