The initial focus will be on production support and ongoing product improvements — investigating and fixing defects, handling requests raised by business users, and implementing enhancements.

• React
• AWS
• Twilio Flex (nice to have)
   

What we’re looking for:

• Strong commercial experience with .NET and React
• Experience working with AWS
• Experience with production support, troubleshooting and bug fixing
• Ability to communicate directly with English-speaking business users
• English — Upper-Intermediate or higher
• Independent and comfortable taking ownership of tasks
• Experience with AI-assisted development tools such as Cursor, GitHub Copilot, Claude Code or similar would be a strong plus
