Philippines onlyRole Overview
We are looking for a Senior Backend Software Engineer with deep expertise in .NET and C# to design and deliver scalable, secure, and high-performance backend services for enterprise platforms.
This role focuses on domain-driven service design, API and integration patterns, event-driven architectures, and building highly observable systems. You will work closely with product managers, architects, and engineers in an Agile environment to solve complex business problems and deliver reliable, evolvable services on cloud platforms.
You will also champion modern engineering practices such as automated testing, CI/CD, infrastructure as code, and AI-assisted development to improve quality, delivery speed, and developer experience.
Key Responsibilities
Backend Engineering & Architecture
- Design, build, and evolve robust and maintainable backend services using .NET / C#
- Model complex business domains and design data structures that support change over time
- Define clear service boundaries, API contracts, and integration patterns
- Contribute to shared backend architecture, standards, and reusable patterns
- Evaluate trade-offs between performance, consistency, scalability, and delivery speed
Integration & Event-Driven Solutions
- Design and implement RESTful APIs with proper versioning, error handling, and contract validation
- Implement asynchronous messaging and event-driven patterns for reliable and decoupled integrations
- Design events that reflect meaningful business state changes
- Support both synchronous and asynchronous service communication
Software Quality & Testing
- Write clean, testable, and maintainable code
- Implement unit, integration, and contract testing
- Build fast, reliable automated regression test suites
- Contribute to test data strategies and quality standards
DevOps, Cloud & Observability
- Work with automated CI/CD pipelines for build, test, security scanning, deployment, and rollback
- Implement infrastructure-as-code and environment automation where applicable
- Deploy and operate services in a cloud environment (Azure or similar)
- Design and maintain logging, metrics, tracing, dashboards, and alerting
- Perform root cause analysis and implement long-term fixes for production issues
Collaboration & Delivery
- Work in a distributed Agile/Scrum team across multiple time zones
- Analyze requirements, identify risks and dependencies, and propose technical solutions
- Participate in architecture and code reviews
- Maintain clear and accurate technical documentation
- Contribute to engineering process and tooling improvements
AI & Developer Productivity
- Use AI-assisted development tools responsibly for code generation, refactoring, testing, and documentation
- Help define effective team practices for adopting AI in the development lifecycle
Qualifications
Education
- Bachelor’s degree in Computer Science, Software Engineering, Information Technology, or equivalent practical experience

- Experience with asynchronous messaging, pub/sub, and event-driven systems
- Strong automated testing experience (unit, integration, contract testing)
- CI/CD pipeline implementation and optimization
- Infrastructure-as-code and containerized development (e.g., Docker)
- Cloud platform experience (Azure or similar)
- Observability and monitoring (logs, metrics, tracing, dashboards)
- Performance, scalability, and resilience design
Ways of Working & Soft Skills
- Strong systems thinking and complex problem-solving capability
- Excellent communication skills in English for technical and non-technical stakeholders
- Proven ability to collaborate across teams, cultures, and time zones
