Software Engineer, Merchants + Partners

at  Block

Company Description
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 47 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.

Job Description
Cash App Commerce owns our retail payment products including Cash App Pay and Afterpay products which gives our customers the ability to take their money further by opting to pay in full, pay in four, or longer term financing.
As a member of the Merchants & Partners team within Cash App Commerce, you will be responsible for supporting how our payment products are integrated and supported across our vast distribution network, composed of direct merchants (SMB, Enterprise), ecommerce platforms, and payment services providers.
You will build, scale, and maintain Afterpay and Cash App’s API platforms, which includes client authentication, a policy-based authorization framework, webhook configuration and delivery, API observability, and managing our API specifications and versioning strategy across our system.

You will:

• Work cross-functionally with our product, business, and finance teams to support new payment experiences for developers using our APIs and SDKs
• Own the design, development, and maintenance of new features and existing systems
• Design and implement high-volume, highly available (99.99%+), low-latency, distributed transaction processing systems, making thoughtful tradeoffs between consistency and availability when both are not possible
• Build systems that manage customers’ sensitive data and hold Cash App to the highest standards for security and compliance
• See the big picture to design fault tolerant systems so the team can be brave, move fast, and break things, without showing a negative impact to customers

• 3 or more years of software development or equivalent experience
• Experience working with public APIs - either building or consuming them
