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.
