• Support data ingestion, transformation, and validation workflows in coordination with data engineers, AI engineers, and functional SMEs.

• Build reusable front-end and back-end components that can support future enhancements and related Guidehouse delivery efforts.

• Participate in system design, sprint planning, code reviews, testing, deployment readiness, and user acceptance activities.

• Implement automated testing, CI/CD practices, documentation, logging, monitoring, and error handling to support production readiness.

• Troubleshoot defects, performance issues, integration challenges, and user experience gaps across the full application stack.

• Collaborate with stakeholders to translate functional requirements into technical designs and working software.

What You Will Need:

• An ACTIVE and MAINTAINED "SECRET" Federal or DoD security clearance.

• Bachelor's degree. Four (4) additional years of exp can be used in lieu of degree.

• Experience developing dashboards, forms, visualizations, or user interfaces for analytical or operational workflows.

• Experience working in cloud, containerized, or enterprise deployment environments using CI/CD, version control, automated testing, and DevSecOps practices.

• Ability to work with product owners, functional SMEs, AI engineers, architects, and data teams to translate requirements into working software.

• Strong written and verbal communication skills, with the ability to explain technical concepts to technical and non-technical stakeholders.

• Comfort operating in regulated, audit-sensitive, federal, or DoW environments.
