Senior Backend Developer (.NET)

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.
