Key Responsibilities
## Key Responsibilities
1.
- •Implement RESTful APIs using ASP.NET Core and Entity Framework Core.
- •Deliver unit-tested code covering at least 80% of new logic; this reduces regressions and speeds releases.
- •Why it matters: Reliable, test-covered code keeps production incidents under 2% of releases.
2.
- •Triage issues from logging (Serilog/NewRelic) within 24 hours and deploy hotfixes when needed.
- •Use profiling to identify slow queries and reduce response time by targeted 20–50%.
3.
- •Attend sprint planning, daily stand-ups, and retrospectives; estimate stories and break down tasks.
- •Coordinate with QA to create acceptance criteria and automated tests.
4.
- •Review 3–5 pull requests per week focusing on maintainability, security, and performance.
- •Mentor junior developers through pair programming sessions to raise team velocity by up to 15%.
5.
- •Maintain pipelines (Azure DevOps/GitHub Actions); ensure builds succeed and deployments complete within 10–15 minutes.
- •Automate rollbacks and runbook updates to reduce MTTR.
6.
- •Design microservices or modular monolith components, define interfaces and data contracts.
- •Drive decisions that reduce technical debt and lower future feature delivery time by measurable amounts.
7.
- •Apply secure coding practices (OWASP) and perform dependency updates to address vulnerabilities within 30 days.
8.
- •Maintain API docs, runbooks, and architecture diagrams; host brown-bag sessions quarterly.
Actionable takeaway: Prioritize testable, observable code; plan work in weekly slices; and measure impact (latency, test coverage, deployment time) to show progress.
Required Qualifications
## Required Qualifications
### Technical skills (must-have)
- •C# and .NET Core (3+ years): Build APIs, background services, and libraries; used daily for feature delivery.
- •ASP.NET Core / Web API: Create endpoints, model binding, middleware, and versioning for public/internal APIs.
- •Relational databases and SQL (SQL Server/Postgres): Write optimized queries, use indexes, and tune queries to cut latency by 20%.
- •ORM experience (Entity Framework Core): Migrations, context design, and performance profiling.
- •Unit and integration testing (xUnit, NUnit, MSTest): Maintain automated test suites with 70–90% coverage on new modules.
- •Source control and CI/CD (Git, Azure DevOps/GitHub Actions): Commit best practices, pipeline configuration, and automated deployments.
### Technical skills (nice-to-have)
- •Docker and container orchestration (Kubernetes): Containerize services and support staging/production deployments.
