  • Experience with AWS, Docker, and modern deployment practices
  • Experience with testing, code reviews, and maintaining high code quality standards
  • Ability to translate user needs into technical solutions while maintaining engineering best practices.
Benefits

  • 401k match with immediate vesting.
