Role Overview and Core Responsibilities
Lead the technical design and hands-on development of customer-facing web applications, Java-based backend services, microservices, and RESTful APIs.
Translate business and technical requirements into detailed application designs and independently drive projects from design through implementation.
Remain actively involved in coding while guiding junior and mid-level engineers, reviewing code, and promoting software-engineering best practices.
Develop and support full-stack solutions using Java, Spring Boot, Oracle/SQL, JavaScript, HTML, CSS, and related technologies.
Partner with production support teams to investigate application issues, troubleshoot front-end and backend components, identify root causes, and bring findings back to the development team.

Promote responsible adoption of AI-assisted development tools and mentor engineers on practical AI use cases within software development and product delivery.
Required Knowledge and Experiences
A minimum of 10 years of software-development experience, including at least 8 years of hands-on experience within the Java and Spring ecosystem, with the ability to design and code rather than operate solely as a project or people leader.

Full-stack development experience with JavaScript, HTML, CSS, and jQuery, along with the ability to troubleshoot both front-end and backend application components.
Strong experience with Oracle Database, SQL programming, relational database design, data structures and algorithms, system design, JSON, YAML, and JUnit-based unit and integration testing.
Development and production-support experience using Git, Maven, Jenkins, Splunk, Grafana, SonarQube, Linux/Unix, and shell scripting.
Working knowledge of Large Language Models (LLMs), Prompt Engineering, Retrieval-Augmented Generation (RAG), AI-powered search, and AI-assisted development tools such as GitHub Copilot, Microsoft Copilot, ChatGPT, or comparable platforms.

Applying security, governance, privacy, and responsible AI practices when evaluating or implementing AI-enabled solutions.
