Job description

Key Responsibilities

• Backend Architecture & API Design: Architect, build, and maintain scalable backend services and
• RESTful APIs using .NET 8 / .NET Core and C# to power modern web applications and automated workflows.
• High-Performance SQL & T-SQL Engineering: Design and optimize complex SQL Server / T-SQL queries, stored procedures, indexing strategies, and transactional data access patterns tailored for high-volume, low-latency execution.
• Database Modernization & Tuning: Identify and resolve database bottlenecks, optimize data structures, write efficient migration scripts, and minimize query latency across legacy and modernized platforms.
• System Modernization: Lead technical efforts to modernize legacy application logic (e.g., ASP.NET MVC, Web Forms, or monolithic backend services) into modular, service-oriented, or microservices-based cloud architectures.
• Integrations & Cloud Services: Build robust integration pipelines and connect backend services to cloud platforms (Microsoft Azure) and third-party tools via clean, decoupled API contracts.
• Code Quality & Technical Standards: Establish best practices for unit testing (NUnit/xUnit), code reviews, database performance tuning, design patterns (SOLID principles), and automated CI/CD deployment pipelines.
• Cross-Functional Collaboration: Partner with frontend developers, database admins, and product managers to define technical requirements, scope sprints, and eliminate architectural bottlenecks.

Required Qualifications & Technical Skills

• Experience: 5+ years of professional backend software engineering experience with the .NET ecosystem and SQL Server.
• Core Tech Stack: Advanced hands‑on expertise in C#, .NET Core / .NET 8, ASP.NET Web API, and RESTful web service architecture.
• T‑SQL & Database Mastery: Deep hands‑on experience with SQL Server, advanced T‑SQL (complex joins, CTEs, window functions, stored procedures, user‑defined functions), query plan analysis, indexing optimization, and Entity Framework / EF Core.
• Performance Tuning: Proven capability in diagnosing database performance issues, minimizing query locks/deadlocks, and engineering data access layers built for reliability and speed.
• Architecture Patterns: Solid experience with microservices, dependency injection, asynchronous programming, and domain‑driven design principles.
• DevOps & Testing: Hands‑on experience with unit testing frameworks, Git version control, and standard CI/CD pipeline tools (Azure DevOps / GitHub Actions).

Core Competencies & Cultural Fit

• Self‑Motivated Learner: Driven to stay ahead of technical trends, evaluate new architectural patterns, and continuously sharpen backend, T‑SQL performance, and cloud skills.
• Strong Individual Contributor & Technical Leader: Able to take ownership of complex backend and database initiatives, ask incisive questions, and drive execution independently with minimal oversight while mentoring mid‑level developers.
• Reliable Team Player: Values transparent collaboration, constructive feedback during code reviews, and strong technical alignment with frontend and QA teams.
• Remote‑Ready Communicator: Clear, prompt, and proactive communication across asynchronous and real‑time tools (Slack, Teams) and project tracking systems (Jira, Azure DevOps).

Preferred / "Nice‑to‑Have" Qualifications

• Experience with cloud platforms (Microsoft Azure App Services, Azure SQL, Azure Functions).
• Experience working on systems integrated with hardware, physical peripherals, or transaction processing workflows.
• Exposure to containerization tools like Docker and integration testing workflows.
• Background in regulated or public sector compliance frameworks (PCI standards, data security, accessibility).
• AI‑Assisted Development: Proficiency in using AI development tools (e.g., GitHub Copilot, Cursor, Claude Code) to write unit tests, refactor legacy T‑SQL/C# code, and accelerate technical delivery.

Required Skills

• NET Core / .NET 8 C# / .NET Core & .NET 8
