Contribute to legacy system migration and data model simplification initiatives. Work cross-functionally to ensure the platform meets company-wide requirements and standards. 10+ years of experience in software development, including at least 5 years in senior roles and 5 years in full-stack development.

Excellent English communication skills and the ability to collaborate in a multicultural environment. Competitive salary with opportunities for professional growth. 100% remote work and flexible work-life balance. 30 days of vacation per year.
