• Build or contribute to end-to-end technical design for new features (including data models) and document key architectural decisions.
• Troubleshoot and resolve technical issues, ensuring application performance, reliability, and security.
• Partner with cross-functional teams to deliver end-to-end solutions, from the UI through back-end services and integrations.
• Produce clear technical documentation and contribute to deployment, monitoring, and ongoing maintenance.
• Support production operations by partnering with System Support to diagnose issues, resolve incidents, and improve reliability across integrated systems.
• Stay current with software engineering and AI best practices, and drive continuous improvement through thoughtful innovation.

Key skills and competences:

• Strong understanding of software engineering fundamentals, including OOP, SOLID principles, and architectural patterns (e.g., CQRS, worker queues, clean architecture, vertical slices, and modular monoliths).
• Demonstrated experience in C#, .NET, JavaScript/TypeScript, and T-SQL for back-end development.
• Experience with Microsoft SQL Server, including schema design and optimization; stored procedures and functions; indexing and performance tuning; and writing efficient T-SQL (DML and DDL).

• Hands-on experience writing production-quality C# (.NET 9/10) with strong unit, integration, and end-to-end test coverage.
• Experience designing and consuming RESTful APIs and SOAP web services using JSON and XML.
• Experience with modern JavaScript frameworks and runtimes (e.g., React, Next.js, Node.js) and integrating them with back-end APIs.
• Experience with ORMs such as Entity Framework Core and/or Dapper.
• Knowledge of OAuth 2.0 and OpenID Connect, including common grant types with Microsoft Entra ID and Salesforce.
• Familiarity with service observability: structured logging, metrics, and distributed tracing (Open Telemetry); dashboards in Application Insights/Grafana; and actionable alerts.
• Familiarity with Azure DevOps, CI/CD, pull requests, and automated quality gates (e.g., code coverage and static analysis).
• Proficiency with Git workflows (branching, merging, and pull requests).
• Strong problem-solving skills, with the ability to assess trade-offs and deliver practical, high-quality solutions.
• Excellent communication skills, both verbal and written, with the ability to collaborate effectively with cross-functional teams.
• Experience working in an Agile development environment, following Scrum or Kanban methodologies.
• Familiarity with message brokers and event-driven patterns with Azure Service Bus, Event Grid, Queue Storage, or RabbitMQ.
• Ability to apply prompt engineering and basic generative AI patterns where they create real business value, and to recognize when they do not.

Optional Skills:

• Experience with AI coding assistants (e.g., GitHub Copilot, Claude, Codex).
• Familiarity with platform observability and edge configuration, including Grafana dashboards and alerts, Argo CD, and managing TLS certificates and DNS via Cloudflare.
• Familiarity with Infrastructure as Code (Bicep or Terraform), with secrets and identity managed through Azure Key Vault and Managed Identities (no connection strings in app settings).

Experience and qualifications:

• Bachelor’s degree in computer science, Engineering, or a related field.
• 6+ years of software engineering experience delivering enterprise applications.
• 5+ years of experience with SQL, database design, and ORMs.
• 4+ years of experience with modern front-end frameworks (React, Next.js, or Blazor) integrated with back-end APIs.
• Proven ability to troubleshoot complex issues in distributed systems.
• Strong sense of ownership and accountability, with a focus on delivering high-quality code.
• Demonstrated experience in developing enterprise applications using modern technologies.
