• Excellent team player with a proven track record of working effectively alongside other developers, QA engineers, and product stakeholders;
• Growth mindset with the ability to adapt quickly, deliver results efficiently, and leverage AI-powered tools to maximize productivity.

Would be a plus:

• Experience with the second backend language (Python/Java);
• Hands-on experience with Next.js;
• Practical experience with WordPress maintenance and customization.

Benefits and Perks:

• Fixed schedule: Sunday–Thursday, 09:00–18:00 (Asia/Jerusalem, GMT+3);
