Senior .NET Engineer - Full Remote Porto Portugal

Job Description

ABOUT THE OPPORTUNITY

Join a Norwegian technology company establishing its tech hub in Porto as a Senior .NET Engineer and work remotely with a highly talented, senior team that emphasizes ownership, trust, respect, and collaboration. 

You'll be working for an innovative Norwegian company building its Portuguese technology presence, creating an environment where experienced engineers can thrive and grow. The team values technical excellence, clean code, and engineers who are passionate about delivering top-notch solutions in a dynamic environment. With a strong focus on modern .NET technologies and Azure cloud services, you'll have the opportunity to work on full-stack applications while taking genuine ownership of projects and technical decisions.

This role offers the perfect opportunity for a self-motivated engineer who is comfortable working remotely in a distributed team setup, values collaboration and open communication, and is eager to contribute technical expertise and innovative ideas. You'll design, develop, and maintain full-stack .NET Core applications, collaborate with cross-functional teams to deliver scalable solutions, and ensure code quality, testing, and best practices are maintained throughout the development lifecycle.

Critical Requirements: This is a mid to senior-level position requiring 5+ years of software development experience with strong focus on .NET Core, full-stack development experience, hands-on GitHub experience, and fluent English communication skills. While the complete requirement combination is complex, the most critical aspects are: strong .NET expertise, some Azure experience, strong ability to learn new technologies fast, and excellent English communication. Portuguese nationality or Porto-based candidates are preferred.

PROJECT & CONTEXT

You'll be designing, developing, and maintaining full-stack .NET Core applications that serve as core products for the Norwegian company's operations. Your work will span both backend development building robust APIs, services, and business logic, as well as building user-facing applications that deliver excellent user experiences. The strong focus on .NET Core means you'll work extensively with modern .NET technologies, C# language features, ASP.NET Core frameworks, and .NET ecosystem tools to build high-quality, performant applications.

Full-stack development defines your daily work - you'll be responsible for the complete application stack from database design and backend API development through frontend implementation and user interface construction. Your ability to work across the full technology stack enables you to deliver complete features independently, make informed architectural decisions considering both backend and frontend implications, and contribute effectively to technical discussions about system design and implementation strategies.

Taking ownership is a core expectation - you'll own projects end-to-end, ensuring code quality through comprehensive testing, code reviews, and adherence to best practices. You'll be responsible for making technical decisions, driving implementation, and ensuring deliverables meet high standards for quality, performance, security, and maintainability. The team trusts engineers to work independently while collaborating effectively, requiring self-motivation, strong judgment, and commitment to excellence.

Collaboration with cross-functional teams is essential for delivering high-quality, scalable solutions. You'll work with product managers to understand requirements, collaborate with other developers on architecture and implementation, participate in code reviews providing and receiving constructive feedback, and contribute to team discussions and decision-making processes with your technical expertise and innovative ideas. Your excellent communication skills enable effective collaboration across distributed teams and time zones.

Working with GitHub for version control and collaboration is fundamental to your workflow - you'll use GitHub for code repositories, pull requests, code reviews, issue tracking, and project management. Experience with Git workflows, branching strategies, and collaborative development practices ensures smooth integration with the team's development processes. Demonstrated contributions to GitHub or open-source projects showcase your skills and commitment to the developer community.

Azure cloud services experience is highly valuable for deploying and operating applications in the cloud. While some Azure familiarity is expected, the strong ability to learn new technologies fast is equally important as you'll continuously adopt new Azure services, patterns, and practices. Understanding cloud-native application development, Azure service integration, and cloud deployment models enables you to build modern, scalable solutions.

Identity and Access Management (IAM) expertise is highly valued - experience with Microsoft Entra ID (formerly Azure Active Directory) and general IAM solutions including FIM/MIM, CIAM (AADB2C), and authentication standards like SAML, OAuth, OpenID Connect, and SCIM positions you to build secure applications with robust authentication and authorization. Understanding identity federation, single sign-on, and multi-tenant security patterns is advantageous.

Blazor knowledge represents a significant advantage for building interactive web UIs using C# instead of JavaScript, enabling full-stack .NET development with shared code between client and server. Your Blazor experience enables rapid development of modern web applications while leveraging your .NET expertise across the entire stack.

Working remotely in a distributed team setup requires self-motivation, strong time management, effective asynchronous communication, and ability to collaborate across time zones. You'll participate in video meetings, async discussions, and remote pair programming while maintaining productivity and team connection. Being open-minded, eager to learn, and adaptable to new challenges ensures you thrive in this dynamic environment.
