Staff iOS Software Engineer, Product Platform

The posting, as Block wrote it

The team

Product Platform builds the foundations behind Cash App and Square. We own shared systems, abstractions, and tools that help product teams build high-quality iOS experiences with speed, consistency, and confidence, while shaping how AI-native development is adopted across our engineering organizations.

The role

As a Staff iOS Engineer on Product Platform, you will be a hands-on technical leader and a multiplier for iOS engineering.

You will identify important problems that do not yet have clear ownership, prove a direction through hands-on work, and create systems that other teams can adopt. You will influence iOS architecture, developer experience, performance, reliability, security, and product quality across multiple teams.

This is an individual contributor role with organization-level scope. Your goal is not to become a permanent bottleneck. You will create leverage through clear interfaces, strong documentation, sound technical decisions, and new technical leaders.

• Define technical strategy, architecture, standards, and measures of success across teams and applications.
• Build prototypes, reference implementations, and critical paths that prove a direction before broader adoption.
• Lead multi-quarter migrations and foundational initiatives from proposal through adoption.
• Establish durable practices for testing, observability, performance, release safety, security, and maintainability.
• Improve developer and AI ergonomics so both engineers and coding agents can work effectively with the platform.
• Contribute platform technology to open source when it creates value for the broader engineering community.

Lead as an AI-fluent engineer

• Integrate AI-assisted development tools into daily workflows to drive leverage across product and platform engineering.
• Evaluate emerging tools and practices, building durable, AI-powered platform capabilities where they add clear value.
• Verify AI-assisted outputs and ensure high standards for software quality, security, and reliability.

Drive organizational impact

• Operate beyond your immediate team to identify and address cross-cutting technical problems.
• Lead architecture and design reviews across team boundaries.
• Surface systemic risks before they become customer, seller, or engineering problems.
• Develop senior engineers and create ownership models that distribute expertise.
• Help set technical standards that improve the quality and velocity of iOS development over time.

Collaborate broadly

• Partner with engineers, product managers, designers, and engineering l
