3. Role Purpose

We are looking for a UI/UX Designer to play a critical role in shaping customerfacing experiences delivered under the Visa–client 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

5. 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.

· Push provisioning flow: wireframes and user journey map produced and reviewed with Product Owner and Frontend Engineer.

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

Days 31–60

· 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 61–90

· 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.

6. 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).

7. Required Skills & Experience

· 5–8 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 XD]for 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.

8. Preferred / Nice-to-Have Skills
