Description Summary / Objective The UI/UX Designer is responsible for designing, validating, and clearly defining intuitive, feasible user experiences for complex enterprise systems. This role translates business objectives and user needs into well-defined user flows, functional specifications, and acceptance criteria that are ready for implementation. This position works end-to-end across design, product, and engineering, ensuring that enterprise platforms—such as Billing & Rating—are delivered with clarity, functional correctness, and alignment to business intent. The role leverages UX/UI artifacts, specification-driven practices, and Artificial Intelligence (AI)–assisted techniques to reduce ambiguity, improve delivery quality, and accelerate feedback loops. This is not a purely visual design role; it is a hybrid UX role focused on correct delivery through strong UX understanding, functional precision, and collaboration with engineering teams. Essential Responsibilities • Map end-to-end user journeys, business processes, and friction points to clarify dependencies and improve overall product experience. • Define and document product behavior through: • User flows • Interaction scenarios • Key decisions, assumptions, and edge cases • Design, review, and validate UX/UI artifacts ranging from low-fidelity wireframes to high-fidelity designs, ensuring consistency and functional accuracy. • Create and review interactive prototypes to validate proposals and align with stakeholders. • Collaborate closely with Product Managers, Engineers, and Designers to align on scope, behavior, and implementation details. • Define, document, and validate acceptance criteria aligned with business outcomes. • Apply AI-assisted tools to: • Generate and refine test and validation scenarios • Identify functional gaps, inconsistencies, or ambiguities • Analyze complex workflows and system behavior • Ensure end-to-end functional quality across enterprise platforms, including Billing & Rating. • Perform visual and functional quality assurance prior to release to ensure implementations match approved design and behavior. • Track deliverables, dependencies, and issues using Azure DevOps, and actively participate in Agile / Scrum ceremonies. • Support and reinforce Specification-Driven Development practices across delivery teams. Actively leverage Artificial Intelligence (AI) tools as part of daily design, analysis, and validation activities. Requirements Qualifications • Bachelor’s degree or equivalent professional experience. • 5+ years of experience in UI/UX Design, Product Design, or hybrid UX/Product roles. • Strong foundation in: • UX principles • Interaction design • Functional validation and edge-case thinking • Proven ability to analyze complex processes and translate them into clear, actionable specifications. • Experience collaborating closely with product, engineering, and cross-functional stakeholders. • Familiarity with Agile workflows and delivery tracking tools. • Experience working in Agile / Scrum environments. • Candidates who do not hold the certification upon hire are expected to obtain it within the first 90 days through company-provided Udemy training. • English proficiency (conversational and technical) – REQUIRED • Spanish language skills – Nice to have Preferred Qualifications • Strong experience using Figma for: • User flows • Wireframes and high-fidelity designs • Design systems and reusable components • Familiarity with Google Stitch, Pencil.dev, or other AI-assisted design and prototyping tools. • Experience reviewing implementations against design intent (visual and functional QA). • Exposure to AI-assisted design, quality, or analysis workflows. • Basic understanding of frontend constraints and backend integrations (APIs, data-driven behavior). • Experience working on enterprise, SaaS, financial, billing, or ERP systems. 8 years
