  • Help establish the technical standards for our product’s API and backend
  • Make well-founded decisions on new technology and processes to adopt
  • Monitor and optimize application performance
  • Code responsibly: minimize tech debt, advocate for change or investment as needed, test and monitor everything
  • Mentor, teach, hire, share and have fun!


  • 5+ years experience building production web applications in a corporate or start-up environment
  • Expertise in building highly scalable and resilient services
  • In-depth knowledge of web application and API development
  • Experience in creating and deploying complex systems using AWS, Docker, or equivalent
