About Salesforce

We're Salesforce, the Customer Company, inspiring the future of business with AI+ Data +CRM. Leading with our core values, we help companies across every industry blaze new trails and connect with customers in a whole new way. And, we empower you to be a Trailblazer, too - driving your performance and career growth, charting new paths, and improving the state of the world. If you believe in business as the greatest platform for change and in companies doing well and doing good - you've come to the right place.

We are looking for people who are passionate about building strong, sustainable infrastructure for the Slack iOS client, which is used by millions of people every day. The iOS Product Infrastructure team enables feature engineers at Slack to tackle complicated problems quickly without needing to reinvent the wheel. We're looking for lead engineers who specialize in either UI frameworks or data/networking infrastructure.

As an infrastructure engineer, you like building for the long term and value patterns and structures that allow for maximum flexibility in a constantly evolving product. You excel in leading others and derive joy from mentoring and growing other iOS engineers. You set a high bar for the technical design and code quality of your team. You demonstrate exceptional ownership of not only the area of your team, but across Slack's entire iOS codebase. You have a "can do" demeanor and nothing is beneath you or outside your responsibilities because you do what it takes to deliver the highest quality code and the most impactful features. You are self-directed, innovative, and biased towards action in fast-paced environments. You love to build new things and thrive in ambiguity and even failure.

What You Should Have

• Deep expertise with Swift and iOS frameworks
• Strong understanding of iOS architectural patterns, such as VIPER

• Solid experience designing scalable and maintainable APIs for shared components, frameworks, or systems
• Extensive experience debugging and fixing crashes, UI rendering issues, and performance problems on iOS using Xcode, Instruments, and other tools
• Experience with Combine, Swift Concurrency (async/await, actors), and dependency injection frameworks (e.g., Needle, Resolver)
• Experience with scripting (Python/bash etc)
• Experience with running a/b experimentation
• Ability to monitor and improve app KPIs such as launch time, app hangs, and crash-free sessions
• A disciplined approach to development, testing, documentation and code structure in a team environment
• An interest in guiding, influencing, and growing other engineers and teams
• Deep familiarity with the Xcode ecosystem, CI/CD pipelines, and automated testing tools
• A product-minded approach to engineering, with an eye for software quality and an ability to connect technical initiatives to business impact

Bonus Points

• Experience using Slack and a keen interest in making it better
• A passion for creating accessible applications
• Prior experience on a centralized infrastructure team, serving both internal developer customers and external users
