Verdantas is seeking a part-time Senior UI/UX Project Designer to join our team in Annapolis Junction, MD, Washington, DC, or Reston, VA. In this role, you will design cohesive, workflow-driven experiences for an ecosystem of complex, data-intensive applications. The role translates complex business requirements into end-to-end user experiences, documents how applications work, and carries that understanding from early concept through final stakeholder-approved designs.

• Lead the design of complete, workflow-driven user experiences for complex enterprise applications, including both administrative functionality and end-user workflows
• Document current and future-state user workflows, translating application behavior, user needs, and business requirements into clear interaction models, wireframes, and high-fidelity designs
• Ensure design decisions are carried consistently from discovery through final approved design to minimize implementation gaps and reduce the need for developers to make independent UX decisions
• Design intuitive user experiences for big-data applications, live-data interactions, and complex decision-support workflows

• Create low-fidelity concepts, wireframes, prototypes, and high-fidelity user interface designs that are ready for stakeholder review and developer implementation
• Apply strong UI/UX design practices to improve usability, accessibility, interaction quality, and overall user satisfaction
• Use design tools such as Adobe XD, Illustrator, and Photoshop to produce clear, production-ready interface designs and supporting design assets
• Contribute to reusable design patterns, interface standards, and visual consistency across related applications and product workflows

• Partner closely with product owners, stakeholders, developers, and technical teams to understand needs, clarify requirements, and translate complex concepts into cohesive user experiences
• Facilitate design reviews, incorporate feedback, and drive alignment across business, product, and engineering stakeholders
• Advise teams on UX implications of workflow, data, and technical decisions, helping project teams make user-centered design decisions
• Work directly with technical contributors to support implementation clarity, including annotations, interaction notes, and design handoff documentation

• Collaborate with software developers working in Java Web, NodeJS, AWS, and related environments to ensure designs are feasible, maintainable, and aligned with technical architecture
• Support front-end implementation quality by providing guidance on styling, SCSS/SASS, micro-interactions, and user feedback patterns where applicable
• Work effectively in Agile/Scrum delivery environments and coordinate design deliverables with sprint planning, backlog refinement, and iterative development cycles
• Use version-controlled or Dev Ops-enabled collaboration practices, including Git Lab where required, to support coordinated product delivery

• Review designs for usability, consistency, accessibility, and implementation readiness before stakeholder approval and development handoff
• Provide informal guidance, mentoring, or review…
