Senior Full-Stack Developer (.NET) – Remote

Nettify develops a platform that integrates a hotel's entire guest technology including Wi-Fi, interactive TV with casting, digital signage, and wireless presentations into one system, replacing multiple vendors. The platform is actively growing with new services and features added regularly.

• Experience with Blazor or strong experience with modern SPAs and willingness to work in Blazor and MudBlazor.
• Experience with Azure services including App Services, SQL, storage, monitoring, and deployment pipelines.
• Proficiency in SQL Server schema design, query optimisation, and migrations.
• Practical knowledge of secure development practices including OWASP Top 10, token-based authentication, secrets management, input validation, and audit logs.
• Experience introducing or owning security practices in a team such as review gates, least-privilege access, secure CI/CD, and healthy dependencies.
• Ability to work independently with direct communication, managing backlog and weekly checkpoints.
• Professional-level English.

Nice to have:

• Experience with Vue 3 and TypeScript.
• Networking basics: TCP/IP, VLAN, DHCP, DNS, RADIUS, captive portal.
• Experience with MikroTik RouterOS.
• Linux server administration.
• Android / Android TV development.
• Experience from 24/7 operations in hospitality, telco, internet, or healthcare.

• Own significant parts of the platform, from design to deployment into real hotels, and help decide how it expands with new services and features.
• Solve hard problems across the whole stack (data layer, integration, architecture, security), not just one isolated layer.
• Hold a high security and quality standard across the code: proper authentication, safe handling of secrets, input validation, audit logs, review before anything ships.
• Help shape how the team builds: the review process, standards, architectural decisions.
• Share knowledge across the team and document so that how the system works is not hidden in one head.
