We are looking for an experienced Backend Application Developer to support a long-term enterprise project in Basel. This is a 3-year contract role with the possibility of extension.

• Access & Federation Protocols: Configure and map identity federation integrations across legacy and modernised components by binding application endpoints strictly to modern access frameworks (OAuth2, OpenID Connect, SAML 2.0).
• Environment Deployment Support: Manage, maintain, and provision isolated localized, staging, and continuous testing application runtime environments, orchestrating automated system packaging and localized deployment workflows.
• Defect Analysis & Root‑Cause Remediation: Provide critical tier‑3 engineering diagnostic support, proactively profiling running server systems to detect, reproduce, isolate, and permanently resolve complex technical defects within high‑load production software systems.

Required Skills & Experience

• Strong experience with .NET Framework, including .NET Framework 4.0, .NET Core, MySQL.
• Good knowledge of MVC architecture.
• Strong database experience with Microsoft SQL Server
