Full-time

Company Description

Software Mind develops solutions that make an impact for companies around the globe. Tech giants & unicorns, transformative projects, emerging technologies and limitless opportunities – these are a few words that describe an average day for us. Building cross-functional engineering teams that take ownership and crave more means we’re always on the lookout for talented people who bring passion and creativity to every project. Our culture embraces openness, acts with respect, shows grit & guts and combines employment with enjoyment.

Job Description

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Designing and building modern, scalable solutions from scratch — replacing outdated systems with new platforms built using best engineering practices.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

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 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)

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

Additional Information

Our offer – professional development, personal growth

Flexible employment and remote work

International projects with leading global clients

Non-corporate atmosphere

Language classes

Internal & external training

Private healthcare and insurance

Multisport card

Well-being initiatives
