It all started with an idea at Block in 2013. Initially built to take the pain out of peer-to-peer payments, Cash App has gone from a simple product with a single purpose to a dynamic ecosystem, developing unique financial products, including Afterpay / Clearpay, to provide a better way to send, spend, invest, borrow and save to our 50+ million monthly active customers. We want to redefine the world's relationship with money to make it more relatable, instantly available, and universally accessible.

Today, Cash App has thousands of employees working globally across office and remote locations, with a culture geared toward innovation, collaboration and impact. We've been a distributed team since day one, and many of our roles can be done remotely from the countries where Cash App operates. No matter the location, we tailor our experience to ensure our employees are creative, productive, and happy.

The Role

Cash App's Card Experience team (part of Cash App's Banking group) builds some of the most

creative and experiential

features in the Cash App ecosystem. Our mission is to make the Cash Card the

primary card of choice

for our users by delivering

delightful, seamless end-to-end experiences

around the Cash Card. This team is responsible for the innovative tools that let customers personalize their Cash App Card and enjoy interactive visuals in the app. We design and implement features such as

custom Cash Card designs

(with stamps, emojis, and even hand-drawn artwork),

themed payment interfaces

(unlocking new app themes like special pink or glitter effects when you order unique Cash Cards), and even a

3D interactive model of the Cash Card

right within the app. By pushing the boundaries of mobile graphics on iOS, we ensure that Cash App customers don't just

manage money

they get to express themselves and have fun while doing so.

Our Card Experience team also collaborates with external partners to deliver

unique product experiences

that resonate with our users. We've launched exclusive card designs and in-app content in partnership with well-known artists for example, an exclusive

Sabrina Carpenter -themed Cash Card design with custom stamps, and special promotions like early Cash Card access to

Lil Nas X 's concert presale. These collaborations showcase how our team combines

cutting-edge iOS graphics

with pop culture and brand partnerships to create features that are engaging, shareable, and

truly one-of-a-kind

on the Cash App platform.

You Will

Build innovative graphics features :

Design, develop, and maintain

high-performance

iOS components that power our interactive card experiences from the real-time

3D Cash Card model

to dynamic UI elements for card customization and payment pad themes. You will work with frameworks like

SceneKit / RealityKit

and low-level APIs like

Metal

to render rich 3D content and animations on iOS devices.

End-to-end feature development :

Own features from concept to release. This includes working closely with product and design on creative new ideas (e.g. animated card customizers, AR visualizations), rapid prototyping of

immersive UI / UX

interactions, and building production-quality code for these features.

Performance optimization :

Tackle the challenges of rendering and animation in a mobile environment. Profile and optimize rendering code (CPU / GPU usage, memory) to maintain smooth

60fps+

experiences, even when handling complex scenes or effects. Implement custom shaders or rendering techniques when necessary to achieve visual excellence without sacrificing app performance.

Collaboration and mentorship :

Work cross-functionally with our world-class

designers, animators, and product managers

to refine requirements and translate ambitious visions into reality. Collaborate with Android and backend engineers to ensure a consistent experience across platforms. If you have senior-level experience, you will also mentor other iOS engineers in graphics programming best practices and

push the team's technical capabilities

forward.

Quality and maintainability :

Write clean, well-structured, and testable code. Utilize unit tests and UI snapshot tests to prevent regressions in complex visual features. Participate in code reviews, and help uphold

high engineering standards

for the team. You will also contribute to the technical direction of graphics / AR technologies in the app, evaluating new frameworks or tools (e.g. adopting RealityKit or

Filament

for rendering) and ensuring our graphics stack remains modern and robust.

You Have

4+ years of iOS development experience

building high-quality apps in Swift (Objective-C experience or interop is a plus). You have a track record of shipping user-facing features and can point to work that

delights users

with its polish and reliability.

Graphics / AR expertise :

Hands-on experience with

3D or AR frameworks

on iOS. This could include SceneKit, RealityKit, ARKit, SpriteKit, or even game engines and custom OpenGL / Metal rendering. You understand the fundamentals of 3D math, rendering pipelines, and maybe have dabbled in writing shaders or using engines like

Filament

for physically-based rendering.

UI / UX and animation skills :

You've built rich custom UI components or complex animations on iOS (Core Animation, UIKit Dynamics, or SwiftUI animations). You enjoy making UIs that are not only functional but

fun and engaging

for example, interactive onboarding flows, creative drawing tools, or playful micro-interactions in apps.

Performance-minded : Knowledge of optimizing app performance, especially graphics rendering and memory usage on mobile. Comfortable using instruments and profiling tools to diagnose rendering hitches, memory leaks, or CPU bottlenecks. Ability to implement optimizations (down to Metal or C++ level if needed) to achieve smooth performance.

Collaborative and creative problem-solver :

Able to work closely with designers, product managers, and other engineers. Open to brainstorming creative solutions and

experimenting

with new technologies or approaches to bring a vision to life.

Bonus points : Experience in

Augmented Reality

development, game development, or visual effects on any platform. Contributions to graphics or animation libraries, or a portfolio of personal projects (apps, games, demos) showcasing your graphics skills. A passion for pushing the limits of what mobile apps can do making something people didn't expect their phone could do!
