Job description

Role Mission

The Application DevOps Engineer will be involved in the end-to-end delivery lifecycle including solution design, application development, QC testing, CI/CD automation and continuous optimization of cloud-native platforms. The candidate will need to manage Kubernetes operations, infrastructure provisioning and software upgrades to ensure systems remain reliable, secure and scalable. The candidate will be working in a team in routine on-call rotations to support day-to-day operations, incident resolution, customer care and defect fixes.

Key Responsibilities

Design and Development

• Design, develop, and maintain robust, scalable, and resilient microservices using Java, Spring Boot and related frameworks.


• Hands-on experience with Apache Camel and its core Enterprise Integration Patterns (EIPs).


• Implement RESTful APIs and ensure services meet performance, security, and stability requirements.


• Write clean, well-tested, and efficient code following best practices and design patterns.

Containerization and Deployment

• Develop and manage services deployed on OpenShift/Kubernetes, including defining Dockerfiles and Kubernetes resource configurations (Deployments, Services, ConfigMaps, etc.).


• Work with CI/CD pipelines (e.g., Jenkins) for automated build, test, and deployment.


• Monitor and troubleshoot services running in the OpenShift environment.

Architecture and Data

• Contribute to the architectural design of microservices, focusing on principles like loose coupling, high cohesion, and fault tolerance.


• Implement various data persistence technologies, including relational (e.g., PostgreSQL) and NoSQL databases (e.g., MongoDB, Redis).


• Integrate services using messaging systems (e.g., Red Hat AMQ) where required.

Collaboration and Quality

• Perform code reviews to maintain code quality and share knowledge within the team.


• Ensure compliance with security standards and industry regulations by performing security vulnerability scans (SAST, DAST, SCA) and disaster recovery exercise.


• Support on-call duty on shift rotation and handle production incident and root cause analysis with minimal supervision.

Knowledge Management

• Build technical documentation from scratch, maintaining working documents on architecture overviews, API specifications and system integrations.


• Create and maintain operational runbooks to support the team and internal stakeholders.

Qualifications

• Bachelor’s degree in Computer Science, Software Engineering, or related field.


• Java Expertise: Minimum of 3 years of professional experience in developing enterprise applications using Java and the Spring Boot framework.


• Microservices and API: Strong understanding of microservices architecture, principles, and best practices. Experience designing and consuming RESTful APIs.


• Containerization: Proficient with Docker and Kubernetes/OpenShift for deployment and orchestration. Experience with OpenShift-specific features is a significant advantage.


• Database: Experience with SQL and NoSQL databases.


• Tools: Familiarity with Git, Maven/Gradle, and CI/CD tools.


• Combined experience in DevOps, SRE, or Software Engineering.


• Familiar with containerized environments, Kubernetes internals, and Helm.


• Hands-on production experience with Jenkins and CI/CD best practices.


• Proficiency in at least one programming language (Python, Go, or JavaScript/TypeScript).


• Solid understanding of AWS core services, IAM security, and cost-optimization practices.


• Comfortable with Linux internals, networking fundamentals, and shell scripting.


• Agile mindset with experience working in Scrum teams.


• Excellent communication, documentation, and collaboration skills.
