JetBrains is seeking a highly skilled Senior Kotlin Developer to join our team and work on the Biological Knowledge Base (BioKB) project. This innovative project leverages domain‑specific languages (DSLs) for both storing and querying complex biological data. Your primary responsibility will be to enhance and maintain our robust query engine, which is instrumental in executing user‑defined queries across the entire knowledge base. Given the extensive nature of the data, efficiency in query execution is paramount. All queries are formulated using our custom DSLs.

In this role, you will:

• Adapt the query engine to evolving project requirements and data models.
• Contribute to the design and evolution of the query DSL.
• Participate in the design of the knowledge base DSL.
• Fulfill general backend development duties, contributing to the overall architecture and stability of the system.

We will be happy to have you on our team if you have:

• Proficiency in Kotlin.
• Experience with Spring Framework.
• Demonstrated experience in microservices architecture.
• Hands‑on experience with SQL, NoSQL, and graph databases.
• Familiarity with AWS cloud services.
• Proficiency with Docker and Kubernetes.
• Strong software design and architecture skills.

We will be especially thrilled if you have:

• Experience with domain‑specific language (DSL) development and usage.
• Experience with projectional editor development and usage.
• Knowledge of graph algorithms.
• An understanding of parsing, lexical analysis, and compiler/interpreter design principles.
• Familiarity with biological concepts or bioinformatics.
