Sourcing as a channel, not a feature.
hackajob is partnering with Sage to fill this position. Create a profile to be automatically considered for this role—and others that match your experience.
The Senior UX Designer leads design and proof-of-concept development for AI use cases across Sage’s product portfolio. You will define and validate high-value opportunities, design intuitive end-to-end workflows, and build clickable POCs that demonstrate user value and guide productization. You’ll partner closely with engineers, data teams, and business stakeholders to ensure AI features are usable, trustworthy, and adoption-ready, and you’ll create clear demos and enablement assets that align decision-makers.
*** Please note: This is a hybrid role requiring 3 days per week in our Johannesburg office ***
Product Discovery, Use-Case Definition & Validation
• Identify, frame, and prioritize AI use cases grounded in customer workflows and product strategy.
• Run discovery, research, and use-case validation (problem statements, hypotheses, success criteria).
• Convert insights into experience concepts, acceptance criteria, and product requirements.
Experience & Interaction Design (Design-Led)
• Own UX design for AI features: user journeys, flows, wireframes, interaction patterns, microcopy, error/edge states.
• Define explainability, user controls, consent, and feedback loops to build trust in AI.
• Maintain alignment with Sage’s design system and accessibility standards; contribute patterns for AI interactions.
Proof-of-Concept (POC) Design & Build
• Design and build interactive, clickable POCs that simulate real workflows and system behaviours prior to full build.
• Collaborate with engineering/data to mirror intended logic (inputs/outputs, guardrails, model interaction points).
• Test with internal users/customers; iterate quickly based on usability and feasibility signals.
• Translate validated POCs into clear handoff specs and “definition of ready” for product teams.
Workflow Definition with Engineering & Stakeholders
• Facilitate cross-functional alignment on scope, sequence, and operational constraints.
• Document end-to-end workflow maps, API/context needs, and UX acceptance criteria.
• Partner on technical trade-offs while protecting user value and simplicity.
Narrative, Demos & Asset Creation
• Produce high-quality demo scripts, walkthrough videos, and visuals to communicate value and intended experience.
• Present prototypes and recommendations to executives, product councils, and GTM teams to drive decisions and adoption.
• Support enablement with concise messaging that explains the “why” behind the experience.
Skills & Experience
Required
• Demonstrated track record in UX/interaction design and hands-on prototyping for complex products.
• Experience defining and validating AI-enabled workflows (inputs/outputs, confidence, explainability, error handling).
• Strong collaboration with engineering/data; ability to translate experience intent into actionable specs.
• Excellent storytelling—turns concepts into clear demos and narrative assets.
• Comfort with ambiguity and rapid iteration; balances desirability, feasibility, and viability.
Preferred
• Background in product management or innovation within B2B SaaS.
• Experience with conversational UX, copilots/assistants, recommendations, or automation flows.
• Familiarity with usability testing, telemetry/experiment design, and metrics for adoption & trust.
