Job Title: UI/UX Designer

Term: 12 months

Location: Nairobi, Kenya

Reports to: Technical Program Manager

Level: Intermediate/ Senior (5-8 years relevant experience)

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

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.

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

• 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.

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.
• Familiarity with tokenization user journeys or digital wallet provisioning flows (Google Pay, Apple Pay, or comparable).
• Knowledge of motion design and micro-interaction principles for mobile UX.
• Experience with A/B testing or multivariate testing frameworks for UI optimization.
• Familiarity with accessibility auditing tools (Axe, Lighthouse, or equivalent).
• Basic understanding of frontend/mobile development constraints (useful for design-engineering collaboration).
