You will diagnose bottlenecks, propose remediation, and contribute to documentation and runbooks while mentoring junior engineers. Strong English communication is essential.

Qualifications

• 6–10 years of professional software engineering experience.
• Deep expertise in C# and .NET — ASP.NET Core, Web API, Entity Framework Core.
• Strong command of object-oriented design and enterprise software fundamentals: SOLID, clean/layered architecture, design patterns, separation of concerns.
• Solid relational database skills, ideally on Azure SQL Database / SQL Server: normalized schema design, T-SQL, stored procedures, transactions and isolation levels, performance profiling.
• Hands-on experience with Microsoft Azure in production — API Management, App Service, Functions, Key Vault, Blob Storage, Service Bus or equivalent messaging.
• A genuine habit of writing documentation — technical design docs, ADRs, API specs (OpenAPI/Swagger), runbooks.
• Strong written and spoken English; able to communicate technical trade-offs to non-technical stakeholders.

Responsibilities

• Design, build, and maintain backend services and APIs in C# / .NET for appointment booking and patient facing platform.
• Diagnose and resolve scalability bottlenecks — data model constraints and integration pain points, with remediation plans.
• Model and optimize data in Azure SQL Database: schema design, indexing, query tuning, and migration planning.
• Build and manage APIs on Azure API Management, and deploy services across Azure App Service, Functions, and related components.
• Contribute to the front end — React Native for mobile and React.js for web, working closely with design and product.
• Integrate with HIS/HMS modules, doctor rostering, payments, notifications, and identity providers.
• Write clear technical design documents and API documentation for traceability.
• Enforce engineering discipline via code review, automated testing, and CI/CD; mentor mid-level engineers.
• Work with clinical ops, customer support, and product stakeholders to translate operational problems into technical solutions.

Job description

• Design, build, and maintain backend services and APIs in C# / .NET for our appointment booking and patient facing platform.
• Diagnose and resolve current system limitations — scalability bottlenecks, data model constraints, scheduling logic gaps, and integration pain points — and propose realistic remediation plans.
• Model and optimize data in Azure SQL Database: schema design, indexing, query tuning, and migration planning.
• Build and manage APIs on Azure API Management, and deploy services across Azure App Service, Azure Functions, and related Azure components.
• Contribute to the front end — React Native for mobile and React.js for web — working closely with design and product.
• Integrate with hospital systems and third parties: HIS/HMS modules, doctor rostering and slot availability, payment gateways, notification channels (SMS, email, WhatsApp), and identity providers.
• Write clear technical design documents and API documentation, so decisions and behavior remain traceable long after the ticket closes.
• Enforce engineering discipline through code review, automated testing, and CI/CD; mentor mid-level engineers.
• Work with clinical operations, customer support, and product stakeholders to translate real operational problems into sound technical solutions.

Qualifications:

• 6–10 years of professional software engineering experience, with a strong track record of delivering and maintaining production systems.
• Deep expertise in C# and .NET — ASP.NET Core, Web API, Entity Framework Core, async/concurrency, dependency injection.
• Strong command of object-oriented design and enterprise software fundamentals: SOLID, clean/layered architecture, design patterns, separation of concerns — and the judgment to know when not to over-engineer.
• Solid relational database skills, ideally on Azure SQL Database / SQL Server: normalized schema design, T-SQL, stored procedures, transactions and isolation levels, performance profiling.
• Hands‑on experience with Microsoft Azure in production — API Management, App Service, Functions, Key Vault, Blob Storage, Service Bus or equivalent messaging.
• A genuine habit of writing documentation — technical design docs, ADRs, API specs (OpenAPI/Swagger), runbooks.
• Strong written and spoken English; able to communicate technical trade-offs to non-technical stakeholders.
