To succeed in this role, you’ll have:

  • Practical experience building with AI/LLM technologies, not just using AI tools casually

  • Strong Ruby on Rails experience, ideally at a senior level

  • Good judgment about when AI is useful and when simpler engineering is better

  • Strong backend skills, including databases, API design, performance, background jobs, and security

  • Ability to break down ambiguous problems into clear technical solutions
Nice to have:
  • CI/CD, background jobs, or AWS experience

  • Experience with text\-processing, localization, translation, or multilingual products
Benefits

Why Join OTGS?* Stable \& self\-funded: Founded in 2007, profitable, and independent.
