Kerja Sepenuh Masa Senior .NET Developer (2 Year Contract), Gaji tinggi SGD 8,200 di MORGAN MCKINLEY PTE. LTD. Islandwide (Singapore) - Maukerja

About the Role

We're looking for a Senior .NET Developer to join the team building and maintaining our enterprise ITSM and platform automation ecosystem — a suite of ASP.NET Core APIs and services that integrate with directory services, service management tools, and internal data stores, backed by React-based front-end applications. You'll own backend services end-to-end, from design through deployment, and work closely with frontend and automation engineers to deliver reliable, secure, and well-tested systems.

What You'll Do

• Design, build, and maintain RESTful APIs and backend services using .NET 8 / ASP.NET Core
• Work with PostgreSQL (via Npgsql/Entity Framework) to design schemas, write efficient queries, and manage data access layers
• Implement and maintain authentication/authorization flows, including JWT bearer auth, Windows/Negotiate authentication, and LDAP/Active Directory integration
• Integrate backend services with third-party and enterprise systems (e.g., ServiceNow-style ITSM platforms, directory services, internal data APIs)
• Collaborate with frontend engineers to design clean API contracts consumed by React/TypeScript applications
• Containerize services with Docker and support CI/CD pipelines (Jenkins, GitLab CI)
• Write unit and integration tests, participate in code reviews, and uphold code quality standards (e.g., SonarQube)
• Troubleshoot and resolve production issues across the stack, with structured logging (log4net) and observability practices
• Contribute to architecture decisions for new services and the evolution of existing ones

Requirements

• Bachelor's Degree in Computer Science, Computer Engineering or equivalent.
• 5+ years of professional experience building backend services in C# / .NET (ASP.NET Core preferred)
• Strong understanding of REST API design, authentication/authorization patterns, and secure coding practices
• Experience working with relational databases (PostgreSQL, SQL Server, or similar) and ORMs (Entity Framework or equivalent)
• Familiarity with containerization (Docker) and CI/CD pipelines
• Experience with version control (Git) and collaborative development workflows
• Strong debugging, troubleshooting, and problem-solving skills
• Clear written and verbal communication, with the ability to work cross-functionally with frontend, QA, and infrastructure teams

Nice to Have (Advantages)

• Full-stack development experience — comfort working across the stack with React/TypeScript front ends, from API design to UI integration
• AI/ML knowledge — familiarity with applying AI/LLM tooling to developer workflows, automation, or product features (e.g., integrating LLM APIs, prompt engineering, or AI-assisted development practices)
• Automation experience with Python and/or Ansible Automation Platform (AAP) — building or maintaining scripts, playbooks, or jobs for infrastructure automation, compliance checks, or operational tooling

What Makes You Stand Out

• Exposure to hybrid environments where .NET services, Node/React front ends, and Python-based automation coexist and need to interoperate
• A track record of improving reliability, security, or maintainability of backend systems in a production environment
