CQUE
We’re building a brand-new technology hub in Kraków for an established US-based product company working in the film & creative industries.
This is not just another backend job — this is your opportunity to shape new products, join from day one, and grow within a stable, global organization with real decision-making power in Poland.
You’ll be part of a newly formed core team, working on greenfield projects with full autonomy, long-term perspective, and excellent career development paths inside the company.
We don’t look for “9-to-5 coders.” We’re searching for talent and personality — curious engineers who want to grow, build long-term value, and make an impact.
Your Role
Design and build scalable backend systems using C# / .NET 6+, Blazor, MVC, and modern architecture
Develop robust REST APIs, backend services, and microservices
Work closely with frontend teams (React) and product stakeholders to deliver high-quality SaaS features
Use cloud infrastructure on AWS (EC2, Lambda, S3, API Gateway, DynamoDB, etc.)
Write clean, tested, maintainable code, with focus on performance and scalability
Take part in architectural decisions and build technical foundations for long-term growth
Participate in unit, integration, and end-to-end testing
What We’re Looking For
5+ years (L3) of backend development experience with SaaS or web-based applications
Strong expertise in C#, .NET 6+, ASP.NET, MVC, Blazor, Entity Framework
Database experience with SQL Server, understanding of distributed systems
Practical knowledge of AWS services and cloud-native development
Passion for clean architecture, testing, automation, and well-structured code
Strong communication, team collaboration, and proactivity
Bonus points for experience with:
AWS Lambda, DynamoDB, Elasticsearch, API Gateway
Terraform / IaC, Docker, Kubernetes
GraphQL, CI/CD pipelines (GitHub Actions, TeamCity)
Monitoring & observability tools
React or frontend collaboration experience
Why You’ll Love Working Here
Greenfield projects – real tech ownership from day one
Direct cooperation with an international product company
Decision-making power – your voice shapes both product and architecture
Clear growth paths – mentoring, training budget, and internal career tracks
Multicultural & creative team – work with people passionate about tech and media
Stability of a global company with the agility of a startup
Hybrid flexibility - 2 days from the office from Krakow/3 days remotely
Continuous development – sponsored trainings, conferences, knowledge-sharing
Paid leave and friendly, people-first culture
We're hiring for attitude, mindset, and vision — not just tech stack.
Join us and help build something meaningful from the ground up.
