As part of its growing EED support team, STC is seeking a Senior UI/UX Developer to support the Consolidated Cumulus User Experience (Dashboard) team.

The Senior UI/UX Developer is a senior technical SME and implementer focused on improving the user interface components of the Cumulus Dashboard — from design through production deployment.

• Produce and manage comprehensive software documentation for all developed features.
• Integrate technical requirements and inputs from the Systems Architect, Systems Engineer, and Cloud-Infrastructure Engineer.
• Ensure all architectural and infrastructure designs maintain strict adherence to documented SLAs.
• Execute CI/CD, system testing, and performance testing for all Cumulus Dashboard software updates.
• Maintain standards-driven CI/CD pipelines and provide automated testing support.
• Maintain comprehensive software documentation and automated unit/integration tests for all new platform features.
• Perform system sustainment tasks, including security updates and Cumulus system health monitoring.
• Address bugs or issues in accordance with the SLA.
• Perform deep-dive root cause analysis (RCA) to prevent recurring technical failures.
• Proactively communicate system status and resolution progress to the UX Product Owner, Operations Manager, and Data Operations Team Leads.

In addition to standard development responsibilities, the Senior UI/UX Developer is specifically responsible for:

• Designing, developing, and publishing UI components — from concept through operational deployment — for the Cumulus Dashboard.
• Applying expert-level front-end design principles to build scalable, accessible, and high-performance user interfaces.
• Collaborating with UX designers, domain experts, and backend engineers to translate specialized requirements into intuitive operational interfaces.

Job Requirements

• 6+ years' software engineering experience, including Agile development (preferably Scrum or SAFe), using the Atlassian tool suite (JIRA, Confluence, Bamboo), and developing on MacOS X and deploying to Red Hat Enterprise Linux
• Expert-level experience designing, developing, and publishing user interfaces leveraging AWS infrastructure for deployment and hosting
• Proven track record in developing and optimizing core UI libraries, component systems, and APIs
• Demonstrated commitment to automated testing, CI/CD integration, and rigorous documentation standards
