Description

At Credence, we support our clients’ mission-critical needs, powered by technology. We provide cutting-edge solutions, including AI/ML, enterprise modernization, and advanced intelligence capabilities, to the largest defense and health federal organizations. Through partnership and trust, we increase mission success for war-fighters and secure our nation for a better future. 

We are privately held, are repeatedly recognized as a top place to work, and have been on the Inc. 5000 Fastest Growing Private Companies list for the last 12 years. We practice servant leadership and believe that by focusing on the success of our clients, team members, and partners, we all achieve greater success.

We have an immediate need for a hands-on Front End UI/UX Developer to work on the transformation of enterprise applications that have struggled with user adoption. This is not a greenfield role — you'll be handed real products with real friction, and your mandate is to diagnose why users aren't engaging and rebuild experiences that they actually want to use. You'll work at the intersection of design, engineering, and data, embedding your work into AI/ML, analytics, and cloud-native platforms.

User Adoption & Experience Strategy

• Audit existing applications to identify adoption barriers through heuristic analysis, user research, and behavioral data
• Define and drive UX strategy for modernization efforts, translating insights into measurable improvements in engagement and task completion
• Champion accessibility and inclusive design (WCAG 2.1 AA compliance) as a non-negotiable baseline

Front-End Engineering

• Architect and build performant, responsive interfaces using React/Next.js with TypeScript
• Experience with Sonatype Nexus Repository Manager for managing build artifacts, enforcing dependency policies, and supporting secure DevSecOps pipelines
• Develop reusable component libraries and design systems that scale across multiple products
• Integrate data visualization layers (D3.js, Chart.js, or similar) into dashboards that make complex data actionable
• Write clean, maintainable code with proficiency in HTML5, CSS3, JavaScript/TypeScript, and supporting scripting languages (Python, etc.)

Dashboard & Data Visualization

• Design and build interactive dashboards surfacing AI/ML outputs, analytics, and operational metrics
• Collaborate with data engineers and ML teams to ensure visualizations are accurate, performant, and meaningful to end users

Collaboration & Delivery

• Partner with product managers, backend engineers, and stakeholders to move from problem definition to shipped product
• Contribute to code reviews, CI/CD pipelines (Jenkins, Git), and agile ceremonies (JIRA)
• Clearly communicate design rationale and technical tradeoffs to both technical and non-technical audiences

AI/ML

• Experience with modeling AI-augmented development practices using tools like GitHub Copilot or Cursor as part of your standard workflow
• Hands-on experience with AI coding assistants as a genuine productivity multiplier, with the judgment to use them effectively on complex, real-world codebase

Requirements

• 5+ years of hands-on experience in UI/UX design and front-end development, with a portfolio demonstrating measurable impact on user experience
• Proven track record of improving adoption or usability on complex enterprise or government applications — not just building new things, but fixing broken ones
• Expert-level proficiency in React, Next.js, TypeScript, HTML/CSS
• Deep familiarity with WCAG 2.1 accessibility standards
• Experience with data visualization libraries (D3.js, Chart.js, Recharts, or similar)
• Solid understanding of UX research methods: usability testing, journey mapping, heuristic evaluation
• Proficiency with Git, JIRA, Jenkins and Sonatype Nexus for artifact management, dependency governance, and secure software supply chain practices
• Strong foundation in at least one backend/scripting language (Python, Java, SQL)
• Exposure to cloud platforms (AWS, Azure, GCP) and ML concepts is a strong plus
• Bachelor's in Computer Science, Human-Computer Interaction, Software Engineering, or a related field
• US Citizenship required; must be able to obtain and maintain a Federal Security Clearance
