• Work with build systems such as Maven or Gradle to compile, package, test, and manage application dependencies.
• Create and maintain unit tests and integration tests to ensure software quality and reduce production risk.
• Support application build, deployment, and release activities using CI/CD platforms.
• Contribute to automation of development, testing, deployment, and operational workflows.
• Work with public cloud platforms such as Azure, AWS, or GCP to support application deployment and runtime operations.
• Assist with troubleshooting application issues across code, configuration, build, deployment, and cloud environments.
• Collaborate with senior engineers and platform teams to improve reliability, observability, and operational readiness.
• Participate in Agile ceremonies, sprint planning, backlog refinement, and regular engineering discussions.
• Contribute to technical documentation, runbooks, troubleshooting guides, and knowledge‑base updates.
• Learn and apply DevOps/SRE principles including automation, monitoring, incident awareness, and production support practices.
• Support continuous improvement across code quality, testing coverage, deployment reliability, and developer productivity.
• Use AI‑assisted engineering tools where appropriate to help with code analysis, test generation, documentation, troubleshooting, and workflow automation.

Required Skills & Experience

• Hands‑on experience with Java development.
• Experience building applications or services using Spring Boot.
• Experience with Java build tools such as Maven or Gradle.
• Strong understanding of software development fundamentals, including clean coding, debugging, source control, and code reviews.
• Experience writing and maintaining unit tests and integration tests.
• Knowledge of CI/CD concepts and experience working with CI/CD platforms such as GitLab CI/CD, GitHub Actions, Jenkins, Azure DevOps, or similar tools.
• Experience with at least one public cloud platform such as Azure, AWS, or GCP.
• Familiarity with microservices concepts, REST APIs, application configuration, logging, and service deployment.
• Basic understanding of containerisation and cloud‑native application practices.
• Ability to troubleshoot technical issues using logs, metrics, build output, test results, and application behaviour.
• Good understanding of Agile software delivery practices.
• Strong communication skills and ability to collaborate effectively with globally distributed teams.
• Ability to work as an individual contributor while taking ownership of assigned development, testing, and support tasks.

Desired Skills

• Exposure to Kubernetes, Docker, Helm, or container‑based deployment platforms.
• Experience with observability or monitoring tools such as DataDog, Grafana, Prometheus, Splunk, ELK/OpenSearch, or similar platforms.
• Exposure to secure software development practices, secrets management, vulnerability scanning, or cloud security controls.
• Python development experience, including designing and implementing reusable Python packages, shared libraries, automation utilities, or internal developer tools.
• Experience with agent development, including building, configuring, testing, and deploying AI agents or workflow automation agents.
• Exposure to deploying and operating custom AI/ML models in cloud environments, including model packaging, runtime configuration, monitoring, and integration with application workflows.
• Understanding of agentic development principles and best practices, including prompt design, tool/function calling, guardrails, observability, evaluation, testing, versioning, and responsible use of AI‑enabled automation.
• Experience using AI‑assisted tools to improve developer productivity, generate tests, analyse code, automate operational workflows, accelerate incident diagnosis, or enhance observability.
