Microservice Developer

Role & responsibilities

Role Overview

The Microservices Developer will translate business and technical requirements into robust services and APIs. The engineer will work across analysis, detailed design, development, automated testing, CI/CD deployment, production support and root-cause remediation. The role requires strong collaboration with product owners, architects, platform teams, security teams and application stakeholders.

Key Responsibilities

Microservices & API Engineering

• Design and develop independently deployable Java Spring Boot microservices and RESTful APIs using approved engineering standards.
• Define service contracts, data models, validation, transformation logic, error handling, retries, timeouts and idempotency controls.
• Build secure, scalable and maintainable services for internal and external consumption, with clear API documentation.
• Apply suitable design patterns and write clean, modular, peer-reviewable code.

Event-Driven Integration

• Develop event-driven integrations using Apache Kafka or Confluent Kafka, including producers, consumers, schemas and failure-handling patterns.
• Collaborate on integrations involving Azure API Management, WSO2 and other enterprise platforms where required.
• Address data consistency, duplicate processing, replay, ordering and dead-letter scenarios.

Quality Engineering

• Create and maintain automated unit, component and integration tests; support end-to-end and performance testing.
• Participate in code reviews and remediate defects identified through peer review, testing and security scanning.
• Maintain test evidence and achieve agreed code-coverage and quality standards.

DevSecOps & Delivery

• Package and deploy services using CI/CD pipelines, containers and Kubernetes-based environments.
• Use version control, branching, build automation, artifact repositories and environment-specific configuration practices.
• Implement secure-by-design controls, secrets management, dependency hygiene and vulnerability remediation.
• Prepare deployment, rollback and validation steps and comply with change-management requirements.

Production Support & Reliability

• Monitor service health, logs, traces, metrics, API performance and Kafka processing for failures or degradation.
• Triage and resolve incidents, service requests and production defects in line with priority and service-level expectations.
• Perform root-cause analysis, implement permanent corrective actions and update known-error and support documentation.
• Participate in planned releases and on-call support for critical incidents as rostered.

Documentation & Collaboration

• Maintain technical specifications, API definitions, sequence/data-flow diagrams, runbooks, SOPs and release notes alongside code changes.
• Estimate work, refine user stories, communicate risks and dependencies, and demonstrate completed outcomes in Agile ceremonies.
• Collaborate with cross-functional teams to resolve endpoint, platform, security and environment dependencies.
