Position Summary

We are seeking a Software Engineer II to support and enhance a mix of legacy and modern applications used across customer support and internal operations. This is a backend and platform-leaning role, with the majority of the work focused on C#/.NET, SQL Server, services, integrations, authentication, and application infrastructure. While the focus is backend, this is not a backend-only role. Engineers on this team follow problems wherever they lead, which may occasionally include legacy WebForms pages, WordPress integrations, or support-facing UI.

Our engineering teams also make significant use of AI-assisted development tools and agentic coding workflows. This role will use AI as part of the development process while remaining accountable for the quality, security, maintainability, and production readiness of the work.

What You’ll Do

• Develop, maintain, and enhance primarily backend applications and services using C#/.NET and SQL Server.
• Troubleshoot production issues across application code, databases, authentication, configuration, logging, integrations, and deployment environments.
• Work with both modern and legacy .NET systems and make safe, focused improvements to existing applications.
• Contribute to the incremental modernization of legacy systems, including authentication, deployment, observability, and operational improvements.
• Work across services, databases, integrations, and support-facing applications when problems cross system boundaries.
• Create and maintain technical documentation, troubleshooting guides, and investigation notes.
• Collaborate with Product, IT, Help Desk, Customer Success, and other teams to resolve technical issues.
• Use AI-assisted engineering tools for development, code analysis, testing, debugging, and documentation, while critically evaluating AI-generated output before it is used in production.

Qualifications

• Strong hands-on experience with C# and .NET application development.
• Strong SQL Server skills, including stored procedures and data-driven troubleshooting.
• Experience developing and troubleshooting backend applications, services, and integrations.
• Ability to understand unfamiliar or legacy code and make safe, focused changes.
• Experience diagnosing production issues using application logs, database analysis, and other operational data.
• AI development tools such as Claude Code, Codex, or Cursor
• Familiarity with authentication and authorization concepts such as OIDC, claims, roles, sessions, or platforms such as Okta.
• Experience with source control, CI/CD pipelines, testing, and software deployment practices.
• Experience using AI-assisted development tools or a strong willingness to incorporate them into day-to-day engineering workflows.
• Ability to work effectively with both technical and non-technical partners.

Nice to Have:

Experience with VB.NET, IIS, Windows services, Vue/TypeScript, WordPress integrations, & AWS services.
