We are looking for passionate UI/UX Designers who will provide remote support to ACT's digital transformation initiatives by applying user-centered design (UCD) practices throughout the software lifecycle. Your work will focus on ensuring operational needs are met through user research, iterative feedback loops, and the creation of design artifacts such as wireframes, prototypes, and high-fidelity mockups. The role requires collaboration with product managers, developers, and stakeholders to align design priorities with business value while ensuring compliance with accessibility standards and best practices for inclusive design. Designers will actively participate in Agile/DevSecOps teams to guide implementation and communicate design decisions that enhance user experience and mission effectiveness.

Responsibilities:

  • Establish feedback loops with customers and apply the Build–Measure–Learn cycle to guide iterative product development.
  • Conduct user research, including interviews, usability testing, and surveys, to validate design assumptions.
  • Create design artifacts such as sketches, flows, wireframes, high-fidelity mockups, and interactive prototypes.
  • Ensure all design work complies with accessibility standards (WCAG, Section 508) and follows industry best practices for inclusive design.
  • Collaborate with Product Managers on backlog refinement and prioritization to align design priorities with business value.
  • Provide clarification to developers during implementation to ensure user expectations are met.
  • Collaborate within cross-functional Agile/DevSecOps teams, actively participating in standups, demos, and retrospectives.
  • Present and communicate design decisions effectively to stakeholders and senior leadership.

We are happy to hear from you if you have:

  • Proven UI/UX industry experience on complex web and/or mobile application design projects.
  • Strong skills in user research, usability testing, and user-centered design methods.
  • Experience collaborating in Agile/DevSecOps environments, including backlog refinement with Product Managers.
  • Proficiency with modern design and prototyping tools (e.g., Figma, Sketch, Adobe XD, Axure, InVision).
  • Knowledge and practical application of accessibility standards (WCAG, Section 508) and inclusive design principles.
  • Experience producing deliverables such as wireframes, user flows, prototypes, and high-fidelity mockups.
  • Strong communication, facilitation, and stakeholder collaboration skills.
  • Fluent English skills (verbal and written).
  • Portfolio of work demonstrating past design solutions and methodology.
  • Certification in UI/UX or related field (UI Design, UX Analyst, Human-Centered Design) desirable.
  • University degree in Human Computer Interaction (HCI), Human Factors, Human-Centered Design/Engineering, or related discipline.
  • Willingness to work in EST time zone
