## Opis stanowiska

We're looking for a  Senior Ruby on Rails Developer  to join a project for a  US-based HealthTech client .  You'll write and review code, contribute to architecture decisions, optimize performance and care about code quality, working closely with PMs, designers and other developers. You'll use AI every day to move faster, and you'll be the one who makes sure the code is actually correct, secure and maintainable before it gets merged. "AI generated it" isn't done. In healthcare, a subtle bug or a missed edge case costs more than time.   What you'll do    Design and build web applications in Ruby on Rails, including relational database design  Work with cross-functional teams to define, design and ship new features  Write automated tests that cover edge cases and overall reliability  Fix bugs and improve performance  Review code with the same standards, whether a person or AI wrote it  Help define and improve internal standards for maintainability and style  Talk directly with the client when needed: clarify requirements, discuss technical solutions and present your work  Test new tools and workflows, and share what works with the team

## Kogo szukamy

5+ years commercial Ruby and Ruby on Rails  Relational DBs (PostgreSQL); experience with NoSQL, caching, message brokers  Client comms: REST API, WebSockets; auth: JWT, cookies, OAuth  CI/CD, deployment tools, Docker, Git  Design patterns, SOLID principles  Automated tests with RSpec or similar  Architecture contribution: business/functional/non-functional requirements, scalability  Daily use of AI tools; ability to review AI-generated code  Code review: giving and receiving  Fluent English (client calls, demos, technical discussions)  Fluent Polish (internal)  Interest in HealthTech; focus on quality, security, compliance    Nice to have    JS framework: Vue or React  AWS or similar cloud platform  Web servers (Nginx)  HealthTech/pharmacy: HIPAA, e-prescribing, insurance, FHIR  Experience embedded with client, consulting, FDE, or startup multitasking    This role probably isn't for you if:    You treat a ticket as done when code runs rather than tested, reviewed, maintainable long-term  You prefer an unchanged stack/workflow for years; we adopt better tools regularly  You avoid responsibility for merges; here you sign off final code
