Role Purpose

We are looking for a UI/UX Designer to play a critical role in shaping customerfacing experiences delivered under the Visaclient implementation programme. Embedded within a crossfunctional tech squad the role is responsible for designing intuitive buildready user journeys across push provisioning acquiring/payment flows and campaignrelated touchpoints within the MPesa ecosystem.

Working closely with Frontend Engineers and client stakeholders the UI/UX Designer ensures design intent is accurately realised through sprintbased delivery provides UX and branding inputs into initiatives such as Tokenisation

4. Key Responsibilities

• Own endtoend UX delivery for squad features covering user flows information architecture wireframes prototypes highfidelity UI and design QA.
• Design payment and provisioning experiences across push provisioning CYBS/acquiring payment flows and campaignrelated touchpoints within the MPesa app.
• Design user-facing messaging iconography consent flows and visual brand compliance elements for Tokenization initiatives delivered as annotated design specifications.
• Maintain and evolve the MPesa design system ensuring components are reusable documented and aligned to established standards.
• Partner with Frontend Engineers during sprint delivery validating build feasibility reviewing implementations and tracking design defects.
• Enable analyticsready journeys by collaborating with Data Scientists to ensure key user interactions are identifiable and measurable.
• Validate usability through lightweight testing incorporating findings into design refinements ahead of development.
• Produce handoffready design artefacts including annotated designs and specifications for efficient engineering delivery.
• Support propositionspecific journeys including Diaspora consumer onboarding and feature flows.
• Deliver knowledge transfer to client designers covering design methods tooling component usage and usability practices
  
  

Measurable Outcomes & Deliverables
First 30 Days

• Current M-Pesa app design system and component library reviewed; gaps and inconsistencies documented.
• UX audit of existing payment flows (where relevant to squad workstreams) completed; priority usability issues identified.

• Design tools and collaboration environment configured; design file structure agreed with Frontend Engineer.
  

Days 3160

• Push provisioning flow: high-fidelity UI designs completed reviewed and approved by stakeholders; handed off to Frontend Engineer.
• CYBS Acquiring payment UI components: wireframes and high-fidelity designs produced and reviewed.
• At least one usability test or expert review conducted on a key flow; findings documented and design iterations applied.
• Component documentation produced for all new UI components delivered to date; added to design system.
• Design QA process established: at least one round of design QA completed for implemented features.

Days 6190

• CYBS Acquiring UI components implemented and design QA completed; zero critical design defects in staging build.
• Push provisioning flows implementation reviewed and signed off by Designer; live in UAT / staging.
• Diaspora UX inputs delivered (if applicable): flow designs or UX recommendations for diaspora-specific features produced.
• Design system contribution complete: all new components documented named consistently and added to shared library.
• Knowledge transfer: design playbook (v1) produced for client design team covering component library design methodology and usability testing approach. At least two sessions delivered.

Ongoing KPIs

• Deliver timely buildready UX designs that support sprintbased engineering delivery.
• Ensure highquality user experiences through thorough design QA and early identification of usability issues.
• Maintain consistency and scalability by contributing to and evolving the MPesa design system and component library.
• Work closely with engineers and data teams to enable accurate implementation and analyticsready user journeys.
• Transfer design capability to client teams through documentation shared practices and handson collaboration.

Stakeholders & Ways of Working

Agile Ceremonies: All sprint ceremonies; leads design-specific story refinement (user stories for UX/UI tasks); participates in daily stand-ups; presents designs at sprint review.

Reporting Cadence:

• Sprint-level: design delivery status at sprint review.
• Ad-hoc: design blockers (e.g. missing brand guidance stakeholder unavailability for review) escalated to TPM within 24 hours.

Cross-Functional Touchpoints:

• Frontend Engineers (design handoff implementation QA component specification).
• Product Owners / client Product team (requirements alignment design review/approval).
• Data Scientist (analytics event instrumentation alignment within user journeys).
• Backend Engineers (understanding of technical constraints affecting UX).
• Client brand/marketing team (brand compliance visual identity guidance).
  

Required Skills & Experience

• 58 years of UX/UI design experience with at least 2 years in mobile application design for financial services payments or fintech.
• Proven ability to design end-to-end user flows for complex multi-step transaction journeys (payment flows onboarding authentication) in mobile contexts.
• Proficiency in Figma / Sketch / Adobe XDfor high-fidelity UI design prototyping and developer handoff.
• Experience contributing to or maintaining a mobile design system and component library.
• Solid understanding of mobile UX best practices including gesture navigation accessibility (WCAG) and performance-aware design.
• Ability to conduct or facilitate lightweight usability research (heuristic evaluation prototype testing user interviews).
• Experience working in agile/sprint-based delivery environments including structured design handoff and design QA processes.
• Strong communication skills; ability to present and defend design decisions to technical and non-technical stakeholders.

Preferred / Nice-to-Have Skills

• Direct experience designing for M-Pesa mobile money applications or comparable super-app payment ecosystems.
• Experience designing for emerging market users including considerations for lower-literacy contexts low-end devices or intermittent connectivity.
