About the Project

We are looking for two Senior C Developers to optimize a 30+ year-old legacy system used for processing cattle genetic data.

• Hands-on experience with Embedded SQL and Intel OpenMP.
• Strong performance optimization skills.
• Experience working with legacy systems.
• English B2+.
• Experience in AI-first development environments and willingness to use Claude Code daily.

Nice to have: Experience modernizing legacy systems and optimizing ETL pipelines.

• Working hours: 12:00–21:00 or 13:00–22:00 Armenia time.
