- Partner with InfoSec and Data Governance to evidence controls, handle vulnerabilities, and pass security reviews.
- Align to internal Tech Standards for Information Security, Data Governance, and Regulatory Compliance.
- Define, document, and uphold standards for coding, reviews, branching, and versioning (e.g., Trunk based development or GitFlow, mandatory PR reviews, automated quality gates).
- Drive CI/CD excellence (GitHub Actions), including build quality, unit/integration tests, static analysis, and automated deployments.
- Establish and enforce performance, reliability, and maintainability baselines; lead refactoring and modernization where needed.
- Implement comprehensive observability (metrics, distributed tracing—OpenTelemetry) and SLOs for critical services.
Key Skills:
- .NET Expertise: .NET 8, C#, ASP.NET Core, RESTful APIs, background jobs, async programming, dependency injection, unit/integration testing frameworks.
