• 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.
