Jobbeschreibung

The Team Bitcoin at Block builds products and platforms that help make bitcoin, stablecoins, and non-custodial wallets accessible to people around the world. We work across Cash App, Square, and Bitkey to create secure, reliable, high-quality mobile and hardware experiences used by millions of people.

We’re looking for an iOS engineer who loves building products and can move quickly through unfamiliar problems. You’ll work closely with product, design, and engineering partners to turn complex financial capabilities into clear, reliable customer experiences.

As a Staff iOS Engineer on Bitcoin, you will own the technical direction and delivery of a critical area of our iOS product experience with bitcoin and stablecoin. You’ll align product requirements with backend capabilities, resolve dependencies with partner teams, and make tradeoffs across customer experience, delivery speed, security, and reliability. You’ll personally tackle the hardest design and implementation problems while helping other engineers contribute effectively.

Your impact will come from shipping valuable products and making the next release better: fewer recurring problems, clearer interfaces, stronger testing, and practices the team can use independently.

Build and evolve the iOS product

• Build products in iOS related to bitcoin, stablecoin and non custodial wallets.
• Work across interfaces in Cash App, Square and Bitkey.
• Own complex features end to end, including client architecture, service integration, testing, rollout, and post-launch improvements.
• Work with product and design to shape customer journeys, prototype new interactions, and turn open questions into delivery plans.
• Build prototypes, reference implementations, and critical paths that prove a direction before broader adoption.
• Contribute bitcoin and stablecoin technology to open source when it creates value for the broader community.
• Build automated testing, observability, and safe rollout practices into delivery, with security, privacy, and compliance safeguards appropriate to the risks.

Lead as an AI-fluent engineer

• Integrate AI-assisted development tools into daily workflows to drive leverage across bitcoin engineering.
• Evaluate emerging tools and practices, building durable, AI-powered capabilities where they add clear value.
• Verify AI-assisted outputs and ensure high standards for software quality, security, and reliability.
• Contribute to codebases beyond your iOS specialty.
• Operate beyond your immediate team to identify and address cross-cutting technical problems.
• Surface systemic risks before they become customer, seller, or engineering problems.
• Mentor engineers through design discussions, code reviews, and structured guidance that helps them take on greater ownership.
• Help set technical standards that improve the quality and velocity of iOS development over time.
• Work with Android, web, and backend engineers to improve shared product foundations and cross-platform experiences.
• Represent bitcoin iOS in cross-team and company-wide technical discussions.

12+ years of professional software engineering experience, including 4+ years building native iOS products.

• ~ Deep experience building, shipping, and maintaining native iOS products using Swift and Apple frameworks.
• ~ Experience working in large, modular iOS applications, including existing UIKit or Objective-C codebases.
• Experience with build systems, continuous integration and delivery, testing infrastructure, observability, or mobile performance.
