Job Description
Sr. Mobile Product Designer
Employment Type: Freelance
Location: Remote (EST working hours preferred)
Start Date: ASAP
End Date: 07/31/2026
We are looking for a highly experienced Sr. Mobile Product Designer to own end-to-end mobile design for in-store and point-of-sale experiences on iOS and Android. This role is an individual contributor position focused on delivering premium, production-ready UI, thoughtful interaction patterns, and polished prototypes for consumer-facing payment flows (e.g., NFC tap-to-pay, QR code payments, and emerging checkout technologies).
You will be responsible for exploring early concepts, shaping user journeys, and driving designs through to engineering delivery, with an emphasis on visual excellence, motion, and usability at scale. Experience experimenting with AI-enhanced design or prototyping workflows is a strong plus.
What You’ll Do
- Lead end-to-end design for mobile in-store checkout experiences, from discovery through final specifications.
- Design high-fidelity, pixel-perfect UI for iOS and Android, maintaining a high bar for visual craft and consistency.
- Create interactive prototypes (not just static screens) to communicate flows, micro-interactions, and motion behaviors.
- Shape payment experiences such as QR and NFC tap-to-pay, as well as new concepts in rewards, loyalty, and checkout.
- Contribute to and extend existing design systems, patterns, and components while upholding design quality across the ecosystem.
- Collaborate closely with product managers, engineers, content strategists, and researchers in a fast-moving environment.
- Prepare design artifacts, flows, and prototypes to support user research and usability testing.
- Articulate and defend design decisions using visual rationale, data, user insights, and strong design principles.
- Ensure accessibility, performance, and usability standards are met across all deliverables.
Required Qualifications
- 8+ years as a Product/UX/UI Designer with deep experience in mobile consumer products.
- Portfolio demonstrating outstanding visual design quality, refined interaction design, and strong product thinking across iOS and Android.
- Expert-level visual and UI craft: typography, layout, spacing, color, iconography, motion, and micro-interactions.
- Proven track record designing and shipping mobile products at scale, balancing consistency, usability, and brand expression.
- Advanced Figma skills (components, variants, auto layout, prototyping) and strong design systems experience.
- Ability to rapidly explore, iterate, and refine concepts while maintaining polish and attention to detail.
- Experience working in large, fast-paced technology organizations and navigating ambiguity.
- Strong communication skills and comfort presenting directly to senior stakeholders across product and engineering.
- End-to-end ownership mindset: capable of driving work from concept to production-ready specs with minimal oversight.
- Familiarity with modern collaboration and handoff workflows for engineering.
- High standards for quality and a clear point of view on what exceptional mobile experiences look like.
- Bachelor’s degree in Design or a closely related field (or equivalent practical experience).
Nice to Have
- Experience with Notion and motion/animation tools (e.g., Figma advanced prototyping, Jitter, Rive).
- Hands-on use of AI-driven tools in design or prototyping (e.g., generative AI for visuals, flows, or code-assisted prototypes).
- Background in fintech, payments, or e-commerce.
- Experience with 3D animation or advanced motion design.
- Prior startup or high-growth environment experience.
