• Collaborate closely with product, QA, and engineering teams in overlapping EST hours;
• Participate in design discussions and contribute to scalable, maintainable solutions.

• 1+ year of React experience with hooks, state management, and component-driven development;
• 1+ year of Python experience in API development and backend logic;
• Experience working in distributed teams with active collaboration;
• Upper-intermediate English level.
