[RTC] Software Engineer (.NET)

Project – the aim you’ll have

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Designing and building modern, scalable solutions from scratch - replacing outdated systems with new platforms built using best engineering practices.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.

Role – 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

Expectations – the experience you need

• At least 5 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)
• Real experience with AI tools

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
• Someone who isn't afraid to admit they don't know something but can work with the team to find a solution
