About the Job: We're hiring an Intermediate Rails Software Developer to build and maintain the backend services behind atVenu's platform.

• Complete development tasks as assigned and/or review and select stories you can execute, with the support of your leader or an assigned partner or mentor.

• Integrating AI into the software development lifecycle responsibly and effectively.
• Clear written communication and the habits to work well on a distributed team.

Nice to have:
