Backend Engineer

The Backend Engineer is responsible for designing, developing, and maintaining scalable and secure backend services that power digital products. The role requires expertise in software engineering principles, modern development practices, and cloud-native architecture. Engineers must work in an agile, DevOps-driven environment, ensuring high software quality, reliability, and security.

Key Responsibilities:

• Collaborate with Business Analysts (BA) and Product Managers to refine user stories and translate them into technical requirements.
• Work with Quality Assurance (QA) engineers to ensure automated test coverage and proactively fix bugs and defects.
• Partner with DevOps teams to automate build, deployment, and monitoring pipelines.
• Develop and maintain scalable, high-performance APIs and backend services in a cloud-native environment.
• Implement modern software development practices, including TDD, pair programming, and CI/CD.
• Conduct code reviews, enforce security best practices, and ensure software craftsmanship standards.
• Design and document system architecture, ensuring compliance with government security and regulatory standards.
• Optimize and improve backend systems for scalability, observability, and reliability.
• Where applicable, contribute to blockchain and smart contract development.

Experience and Skills Needed:

• Degree/Diploma in Computer Science, Information Technology, Engineering, or related field
• Strong experience in JavaScript development, including:

         o Frontend frameworks (e.g., Next.js)

         o Backend frameworks (e.g., Node.js, NestJS)

• Experience or familiarity with Sitecore ecosystem, including XM Cloud (XMC), OrderCloud (OC), and Sitecore Search (SS)
• Proficiency in Git and modern branching practices (e.g., GitFlow, trunk-based development)
• Experience in API development and integration (RESTful APIs, GraphQL, WebSockets)
• API documentation using Swagger
• Familiarity with microservices architecture and event-driven design patterns
• Experience with cloud platforms (AWS, Azure, or Google Cloud) and deployment platforms (e.g., Vercel)
• Hands-on experience with containerisation and orchestration (Docker, Kubernetes)
• Experience with CI/CD pipelines (e.g., GitHub Actions, GitLab CI)
•  Working knowledge of databases:

       o Relational (PostgreSQL, MySQL)

       o NoSQL (MongoDB, Redis, DynamoDB)

• Exposure to monitoring and observability tools (e.g., Prometheus, Grafana, ELK)
• Experience with additional backend languages (e.g., Java, Python, Go)
• Exposure to Infrastructure as Code tools (Terraform, CloudFormation)
• Experience with API documentation using Swagger.
• Hands-on .NET development experience, including building backend services and APIs using C#, ASP.NET Core, and related Microsoft development frameworks.

Software Engineering Practices

• Experience working in Agile teams (Scrum, Kanban) with strong collaboration skills.
• Knowledge of Extreme Programming (XP) practices such as TDD, pair programming, and continuous refactoring.
• Strong understanding of test automation frameworks (JUnit, PyTest, Jest, Playwright).
• Adherence to software craftsmanship principles, ensuring clean, maintainable, and efficient code.

Bonus Experience (Added Advantage):

• Understanding Domain-Driven Design (DDD) and Clean Architecture principles.
• Experience working with government digital services and authentication mechanisms (SingPass, CorpPass).
• Experience with API gateways and service meshes (Kong, Istio, Apigee).
• Experience with serverless computing (AWS Lambda, Azure Functions).
• Exposure to blockchain and smart contract development (Ethereum, Solidity, Hyperledger).
