Java Developer

Title : Full-Stack Java Developer

Location : Austin, TX (Onsite)

Duration : Long-term Contract

This is a WUD Legacy Modernization Project and the full-stack Java Developer is responsible for designing, prototyping, and developing enterprise web applications that support external permitting and authorization processes. The developer works closely with business users to rapidly translate requirements into SQL-driven prototypes, iteratively refining solutions based on feedback. The role involves building and deploying applications using JEE technologies (JSF, PrimeFaces, Hibernate, Spring) integrated with Oracle databases and web services, while ensuring compliance with security, accessibility (W3C), and agency standards. Responsibilities also include producing technical documentation, developing and executing test plans, supporting CI/CD processes, and collaborating across technical and non-technical teams to deliver scalable, user-friendly solutions in a complex, multi-system environment.

Job Duties:

• Working with the Client's IRD and user staff to develop design documents and SQL-driven screen prototypes from user requirements within a rapid turnaround cycle.
• Assist in presenting the resultant prototype to various end user audiences to demonstrate screen content, dialog, and usability and to identify and incorporate user-requested changes as directed by the technical leader.
• Transform the approved prototype and design into a JBoss JEE, Primefaces, JSF, EJB and Hibernate application for external users to provide external authorization application, issuance, renewal and termination support. To do this, two systems exist to allow Client's Users to set up permit processing data and for external facility owners and operators to request, receive, renew and terminate Client's operating authorization. Systems interact with other agency systems via web services, Oracle database, and proxy technologies.
• Producing module specifications, unit test requirements, and system and integration test requirements.
• Implementing applications in complex environments in an iterative prototype-user evaluation life cycle with later more complete functional versions accessible to select external users via the Internet to verify functional provisions and usability, including access by disabled persons and those using screen readers such as JAWS and the NVDA.
• Developing detailed flowcharts and models, implementing specifications, and performing modifications from design reviews, prototype evaluations and assessment testing.
• Producing running program modules, which meet Client's, DIR and World Wide Web Consortium (W3C) specifications and standards.
• Outlining, formatting, and producing detailed program and user documentation.
• Performing acceptance testing and incorporating necessary changes prior to formal production release implementation.
• Communicating and working with people of all technical levels in a team environment.

Required Skills and Experience:

• Agreement to adhere to all Client's policies, procedures and management directives;
• Experience developing Internet Web browser-based transaction and reporting applications using JSF, Hibernate, J2EE technologies to access an Oracle RDBMS 13g RAC or later;
  • JEE and Spring framework development experience must include:
  • Using modern IDEs (Visual Studio Code, Eclipse) for an application server environment that includes Apache Tomcat 9/10 and JEE app server such as JBoss EAP 7/8.
  • Developing business logic for tiered applications utilizing JSF (2.3 4.0), PrimeFaces (6 - 14), Hibernate (5 6), JDK (1.8, 17, 21).
  • Knowledge of developing and consuming web services (REST).
  • Knowledge of Spring Batch jobs.
  • Knowledge of internet security exposures and how to code to prevent the application from being hacked or hijacked.
• Experience developing Oracle PL/SQL applications and familiarity with Oracle objects (tables, constraints, triggers, etc.);
• Experience with version control (Git, SVN), build tools (Maven), and CI/CD automation (Jenkins) in a configuration-controlled, multi-developer environment;
• Experience with data modeling, entity relationship diagrams, SQL, and Web page user interface design;
• Knowledge of database concepts such as referential integrity and data normalization;
• Experience with Git tools and CoPilot;
• Excellent communication skills, written and oral, with people of all technical levels;
• Five (5) years of full-time experience in computer programming and/or systems analysis;
• Knowledge of the limitations and capabilities of computer systems and their integration with end-user business processes;
• Skill in preparing technical documents of varying complexities for technical and non-technical audiences;
• Skill in working with data automation standards and systems administration technologies;
• Skill in analyzing and interpreting agency organizations, business practices, policies and procedures;
