  • Ensure compliance with security standards (e.g. SOC2) and maintain clear documentation.
  • Dig into production issues—analyze logs, fix root causes, and prevent repeats.
  • Stay ahead—evaluate new .NET features and Azure tools to keep us sharp.

Skills & Experience:

  • Experience: 5+ years with C# and .NET—building web apps and enterprise solutions.
  • Database: Deep SQL Server expertise—stored procedures, triggers, optimization.
  • Cloud: Strong Azure experience—scaling apps, securing services, monitoring with Insights.

  • Must-Have: Proven skills in authentication flows (OAuth, SAML, JWT) and secure coding.
  • Advantage: Experience with microservices, serverless Azure Functions, or front-end (React/Angular).
  • Agile & Collaboration: Ability to lead devs, QA, and ops teams to streamline delivery.
  • Advantage: Familiarity with CI/CD tools (Azure DevOps, Bitbucket Pipelines) or monitoring (Prometheus, Grafana).
