You will join an agile, international team of experienced developers and testers (from Poland and the UK) working on a strategic transformation of the IT ecosystem for a leading travel industry company.

The main goal?
Designing and building modern, scalable solutions from scratch — replacing outdated systems with new platforms built using best engineering practices.

As part of the team, you’ll have a real opportunity to:

co-create new solutions and architecture,
develop Proof of Concepts (PoCs) and test ideas,
drive technical discussions and decisions,
collaborate with other senior and principal engineers,
and leave your mark on a platform that will serve millions of users.

The work is organized in 4-5 agile teams, each focused on a specific product area — allowing you to take ownership while collaborating closely across teams.

This is not about maintaining legacy systems — this is about building something new.

Position – how you’ll contribute

Designing and building new features and solutions from the ground up
Creating Proof of Concepts (PoCs), technical spikes, and validating ideas
Replacing old systems with new architecture — not maintaining legacy code
Performing code reviews and sharing best practices
Participating in shaping product architecture and technical direction
Collaborating with other senior/principal developers, testers, BAs, Product Owners, and Scrum Masters
Supporting the team with your knowledge, experience, and technical leadership

Qualifications

Expectations – the experience you need

At least 6 years of commercial experience in C# and .NET Core
Experience with AWS DevOps tools and CI/CD processes
Solid understanding of software design principles, patterns (e.g., SOLID, DDD), and clean code practices
Experience creating tests (unit, integration, ideally also component or contract tests)
Practical experience with databases (SQL, MongoDB, NHibernate, Entity Framework, Azure Storage)

Additional skills – the edge you have

Knowledge of front-end technologies: Angular (12+), JavaScript, TypeScript, CSS, Git — although in the project you’ll be working closely with a dedicated front-end developer
Experience designing new systems or working on greenfield projects
Familiarity with event-driven architecture and distributed systems
Knowledge of cloud solutions, especially AWS and Azure
Willingness to share knowledge, mentor other developers, and actively participate in technical discussions
