Engineering Lead, Core Experiences & Server Infrastructure

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

As the Engineering Lead for Core Experiences and Server Infrastructure, you will lead the central pillars of the Cash App ecosystem. You are responsible for the foundational products—including P2P, activity feed, social connectivity—as well as the critical product-platform systems like data services, experimentation, and messaging that power every customer experience. Your goal is to drive strategy and execution across all primary user journeys while building the underlying systems that enable product velocity, quality, and scale for thousands of engineers.

You Will

• Bridge the gap between core infrastructure and product engineering, leading cross-functional teams to launch flagship features (e.g., Peer-to-Peer payments) from ideation through global rollout.

• Championed a "Product-First" engineering culture, aligning backend roadmap priorities with user-facing KPIs to reduce friction in the money-movement lifecycle.

• Managed a multi-million dollar annual cloud budget, optimizing server-side resource allocation and infrastructure efficiency without compromising system performance or developer velocity.

• Built and mentored a high-performing team of 50+ engineers, fostering a culture of engineering excellence for one of the world's most visible fintech platforms.

You Have

• 10+ years of experience leading and scaling engineering teams, including managing engineering managers.

• A strong track record of architecting, building and scaling distributed systems capable of processing billions of dollars in transaction volume, prioritizing low-latency execution and transactional integrity across microservices.

• Demonstrated ability to drive strategy, execution, and operational excellence in a complex and regulated environment.
