What You'll Do:

• Develop High-Impact Solutions – Design and build scalable, efficient backend/frontend systems using Kotlin and the JVM stack with a React FE.

• Cross-Team Collaboration – Partner with frontend and backend engineers, product managers, and other teams to align on priorities and deliver end-to-end solutions.
• Improve System Performance – Optimize API performance, database queries, and caching strategies for high-traffic web solutions.
• Mentor and Lead – Provide technical guidance and mentorship to junior engineers, ensuring high engineering standards within the team.

What We’re Looking For:

• Ability and willingness to contribute to both frontend and backend work.
• Experience working on high-traffic web applications and large codebases.
• Strong understanding of API design, architecture, and distributed systems.
• Clear, transparent and regular communication is essential for the team and its stakeholders.
• Comfortable working in a cross-functional team environment, collaborating with product managers, designers, and frontend engineers.
