Cash App
Get AI-powered advice on this job and more exclusive features.
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're 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.
About the Role We're the Access team, and we're building the next generation of authentication and permissions infrastructure for Block. Behind every login and every account there's a platform that needs to be both rock-solid and remarkably flexible. This role is not about maintaining legacy systems; it's about building the foundation that will enable Cash App and Block's ecosystem to scale while serving increasingly diverse customer needs.
The Challenge As Block accelerates product innovation, we see an explosion of new use cases: different account capabilities, different authentication requirements, different customer cohorts with different needs. We are building a platform that lets product teams move fast while we maintain the trust and security that our customers depend on.
The Opportunity You will join at an inflection point. The decisions we make now about architecture, APIs, and how we enable other teams will define how Block scales for years to come. This is foundational work with massive leverage.
What You Will Do
Design and build the APIs and services that power Authentication & Permissions across Cash App and Block's ecosystem, the systems that determine who can access what, and how they prove they are who they say they are. The work is varied and impactful. You might:
Build fine-grained permissions systems that enable different roles and capabilities across various account configurations
Build secure authentication experiences that protect customers while maintaining seamless access to their accounts
Improve account recovery success rates, helping legitimate customers regain access while keeping bad actors out
Consolidate authentication platforms, migrating critical flows into scalable, composable services
Design authorization primitives that product teams across Block can use to build secure, flexible experiences
How you’ll work: You’ll navigate complexity with pragmatism, balance immediate business needs with long‑term platform goals, ship iteratively while keeping the big picture in mind, collaborate across product, design, security, and engineering teams, think critically about priorities, and adapt and thrive in a shifting environment. The common thread: you will solve complex technical problems that directly impact both customer trust and product velocity while balancing pragmatism with technical excellence.
What You Bring
5+ years building and operating production systems with demonstrated impact and technical ownership
Ability to think critically and analyze complex problems, weigh trade‑offs, and make pragmatic decisions that balance competing priorities
A bias toward iterative delivery. You know how to break big problems into shippable pieces and maintain momentum through ambiguity
Comfort with complexity. Whether it's large codebases, distributed systems, or evolving requirements, you don't get overwhelmed; you get strategic
Excellent communication skills. You can explain technical concepts clearly, build alignment across teams, and adapt your style to different audiences
Customer empathy. You understand that behind every API call is a person trying to access their money, and that matters
High technical standards in software testing, delivery, and operational excellence
Adaptability and resilience. You stay calm and focused when priorities shift or requirements change
Even Better If You Have
Experience with authentication, authorization, or identity systems
Experience working in large codebases and breaking apart monoliths
Background in security, fraud prevention, or trust & safety domains
Experience building platform or infrastructure that other engineering teams depend on
Track record working effectively in distributed or remote teams
Technologies We Use and Teach
Java, Kotlin, Golang
HTTP, JSON, gRPC, Protocol Buffers
MySQL, Hibernate, DynamoDB
Kafka and event‑driven architecture
DataDog, Prometheus
AWS, Kubernetes
