Senior Ruby on Rails Developer
We are looking for a senior Ruby on Rails developer to help us build reliable, scalable products and apply AI/LLM technologies where they create real value.
This is a hands-on engineering role for someone who can own complex features end to end, make strong technical decisions, and work across backend architecture, production systems, testing, and AI-assisted product development.
You should be excited about AI, but pragmatic enough to know when a simple, deterministic solution is better than an LLM call.
Co budeš dělat
- Owning features from technical design to production
- Building and maintaining Ruby on Rails systems used at scale
- Designing AI/LLM-assisted features and workflows where they improve product quality or user experience
- Working with LLM APIs, prompts, retrieval/context strategies, and AI-assisted development tools
- Making trade-offs around performance, reliability, cost, latency, security, and maintainability
- Writing and maintaining automated tests, including unit, integration, and E2E tests
- Debugging production issues and improving system reliability
