About the role

We need an engineer who understands the business value behind every feature, collaborates closely with product and stakeholders, and takes end-to-end ownership of outcomes.


The core responsibilities for the job include the following:


Legacy Platform Support:

  • Maintain and enhance existing ASP. NET/C# and SQL Server codebases.
  • Research, troubleshoot, and debug stored procedures and T-SQL.
  • Analyze, design, and develop automated tests to ensure continued functionality during maintenance and enhancements.
  • Create and maintain technical documentation to support future upgrades and system maintenance.


Modernization and Microservices:

  • Collaborate on domain decomposition, domain modeling, and Domain-Driven Design (DDD) for new services.
  • Design, develop, and deploy microservices using C#/. NET on Azure.
  • Build RESTful APIs and event-driven architectures.
  • Work with Azure PaaS services, including Azure App Service, Azure Service Bus, and Azure SQL Database.
  • Support domain-based database architectures and ensure data consistency across services.
  • Enable interoperability between legacy platforms and newly developed microservices during modernization.


Quality and Test-Driven Development:

  • Champion Test-Driven Development (TDD) practices across the engineering lifecycle.
  • Develop automated unit, integration, and regression tests.
  • Build and maintain test-automation suites.
  • Leverage AI-assisted development tools for code generation, test case generation, and technical documentation.
  • Participate in code reviews, static code analysis, and refactoring activities to improve code quality.


Product Mindset and Collaboration:

  • Partner closely with product managers, product owners, and business stakeholders to understand business requirements and objectives.
  • Evaluate alternative technical approaches and balance engineering and product trade-offs.
  • Understand the broader business purpose behind features rather than focusing only on assigned tasks.
  • Collaborate with QA, Infrastructure, Design, and Operations teams to deliver reliable solutions.


Ownership and Accountability:

  • Take end-to-end ownership of features from design and development through deployment and delivery.
  • Support and enhance existing systems and platforms.
  • Monitor production issues, communicate progress, and proactively identify and resolve risks.
  • Ensure engineering work ultimately delivers measurable customer value.


Continuous Improvement:

  • Recommend and implement improvements across engineering processes, architecture, and application performance.
  • Stay current with best practices in microservices, cloud engineering, DevOps, and AI-assisted software development.
  • Mentor team members on TDD, DDD, and software craftsmanship.


Requirements:

  • 7+ years of professional software engineering experience.
  • Strong preference for candidates from a software product company developing products for B2B or B2C customers.
  • Candidates from services/consulting organizations should have strong product engineering experience, preferably in healthcare payments or similar domains.
  • Strong hands-on experience with C#, . NET, and ASP. NET.
  • Strong database programming experience with SQL Server, T-SQL, and stored procedures.
  • Experience with PL/SQL is required.
  • Strong hands-on experience with Test-Driven Development (TDD).
  • Proven experience developing unit, integration, and regression tests and working with test-automation frameworks.
  • Strong understanding of microservices architecture and event-driven architecture.
  • Experience designing and developing RESTful APIs.
  • Hands-on experience with Azure/cloud platforms, preferably Azure PaaS services.
  • Experience with Azure App Service, Azure Service Bus, and Azure SQL Database is preferred.
  • Strong understanding of Domain-Driven Design (DDD) and domain modeling.
  • Experience with modern DevOps practices, including CI/CD pipelines, containerization, and Infrastructure as Code (IaC).
  • Experience working with legacy modernization/migration from monolithic applications to microservices.
