Qualifications

Bachelor's degree in Computer Science, Software Engineering, Information Systems, Engineering, or a related technical discipline, or equivalent relevant experience.
Minimum two (2) years of progressively responsible software engineering or application development experience.
Experience developing, enhancing, debugging, testing, or maintaining enterprise or web-based applications across one or more application layers.
Experience with modern source control and software-development practices, including Git-based workflows, code reviews, and automated testing.
Experience working in Agile development environments and participating in iterative planning, backlog refinement, sprint execution, or Kanban delivery.
Working knowledge of REST APIs, JSON, authentication and authorization concepts, and common integration patterns.
Working knowledge of CI/CD, cloud platforms, containers, automation, or Infrastructure as Code.

Responsibilities

Develop, modify, test, debug, and maintain software components that support OJP digital products, integrations, APIs, automation, and internal platforms under established engineering guidance.
Provide software improvements to existing applications and services by implementing approved enhancements, defect corrections, refactoring, and technical-debt reduction activities.
Translate assigned user stories, acceptance criteria, customer needs, and technical requirements into working software using Agile product-team practices.
Create and maintain automated unit, integration, regression, API, and data tests to improve release quality and reduce recurring defects.
Participate in Git-based source-control workflows, code reviews, pull requests, branching, merging, and configuration-management practices.
Support continuous integration and continuous delivery (CI/CD) pipelines, build automation, security scanning, artifact or container workflows, and repeatable deployment processes using OJP-approved tools.
Develop, consume, test, and maintain APIs and web services through OJP's data-integration environment, including WSO2 API Manager when assigned, using applicable standards and protocols such as REST, JSON, XML, SOAP, and related technologies.
Support API integrations with OJP's Identity and Access Management System (DIAMD), including integrations involving Okta and SailPoint and protocols such as SCIM, OAuth 2.0, and SAML.
Support cloud-hosted and containerized application environments and assist with deployment, monitoring, configuration, security, patching, and troubleshooting activities in coordination with OJP networking and security teams.
Investigate and resolve assigned help desk tickets, software defects, test failures, and technical issues involving Data Integration and DevSecOps products, escalating complex issues when appropriate.
Participate in defect triage, root-cause analysis, corrective-action activities, sprint reviews, retrospectives, backlog refinement, and other Agile delivery activities.
Create and maintain technical documentation, configuration information, user stories, standard operating procedures, test evidence, and implementation notes needed to sustain supported products and services.
Collaborate with software engineers, architects, DevOps engineers, business analysts, product managers, and Government stakeholders to deliver secure, compliant, accessible, and maintainable capabilities.
