We are currently looking for a Senior Ruby on Rails Developer to join one of our clients - a company operating in the luxury travel & hospitality space, managing an exclusive collection of premium properties across the Mediterranean.
Project Description
Our client's engineering team builds and maintains the internal tools that power the client-matching, sales, and operations workflows behind their business. The stack is Ruby on Rails + PostgreSQL (hosted on AWS) alongside Next.js, with a trunk-based repo, CI/CD, and multiple deploys per day. This role is focused on a migration project.
Role is based in Wrocław, Poland. 90% remote work with occasional office visits but Wrocław is important from a stategic perspective.

- Building integrations with external systems (CRM, payment gateway)
- Working with PM/PO to reconstruct domain logic from the old system
- Maintaining code quality and security in the context of sensitive customer and billing data
What we’re looking for
- Solid commercial experience with Ruby on Rails
- Skills in relational database design (normalization, data integrity)
- Basic React familiarity
- Awareness of working in a CI/CD and containerized environment infrastructure
- Understanding of secure application design principles
Nice to have
- Experience with data/system migrations, Pundit, Inertia.js, feature flags
- Knowledge of C#/.NET
- Experience in the travel/hospitality industry or in projects with a strong customer-care focus
