Our Technology Department develops and supports proprietary software used throughout the company. We are looking for a Full-Stack Developer to join our small, collaborative technology and help desk team and take real ownership of the applications and tools you build.

This is an opportunity to work on software that is actually used by our employees every day-not just theoretical projects or client work.

  • Build, test, and deploy full-stack features for internal business applications.

  • Strong knowledge of JavaScript and TypeScript.
  • Experience with Vue, Nuxt, React, Angular, or another modern frontend framework, with the ability to become productive in a Vue/Nuxt environment.

  • Experience working with SQL databases and an ORM.
  • Understanding of database schema changes and migrations.
  • Experience with Git, pull requests, testing, and debugging.
  • Ability to communicate clearly, work independently, and collaborate with a small team.

  • PostgreSQL
  • Redis
  • Tailwind CSS
  • Docker
  • CI/CD
  • Python

  • AI tools, LLMs, or API integrations
Why Work at Midtown?
  • $40,000-$60,000 annual salary, based on relevant experience and demonstrated skills
  • 100% employer-paid health insurance for the employee
  • 401(k) matching
  • Paid time off
  • Paid holidays
  • Annual international company trip - Mexico, Jamaica, and more
