The world of work as we know it is changing and we're looking for Trailblazers who are passionate about bettering business and the world through AI, driving innovation, and keeping Salesforce's core values at the heart of it all.

About Slack:
Slack is your Digital HQ – a place where work flows between your people, systems, partners, and customers. From Fortune 100 companies to corner markets, millions of people around the world use Slack to connect their teams, unify their systems, and drive their business forward. 

Slack breaks down communication silos inside and beyond your organization by bringing teams and tools together around common goals, projects and processes in channels and in Slack Connect. It removes the limits of physical walls, giving people the flexibility to do their best work where, when and how they prefer with features like huddles and clips. And it empowers everyone to automate common tasks with apps and workflows. In this digital-first era, Slack’s mission is to make people’s work lives simpler, more pleasant, and more productive. 

A taste of our scale and reach:

• Slack delivers 300k+ messages per second

• 77% of the fortune 100 use Slack

• 150+ countries have daily active users in Slack 

• To date, 1.79 trillion messages have been sent on Slack 

• 2.65 billion actions are taken in Slack each day

• Slack has 200k+ paid customers

• Users are spending a combined 243 million minutes per week in Huddles

• We're looking for people who are passionate about crafting phenomenal iOS applications.

As a Senior Engineer on this team, you'll have genuine autonomy: shaping the technical direction, making tradeoffs between performance and features, and deciding what gets built next based on user impact.  You'll lead the AI mobile efforts, owning the roadmap and technical strategy for two of our highest-impact user journeys—helping people find what they need and get things done on the go.  This isn't about porting desktop features to mobile; it's about reimagining AI and Search for how people actually work from their phones, leveraging mobile-specific capabilities like notifications, location, and device sensors to build context-aware experiences that feel native.  Mobile is a critical touchpoint for our users, and there's significant untapped potential to drive AI adoption on the platform.  You'll mentor engineers equally passionate about mobile-first thinking while partnering closely with Product and Design.

Senior Engineers at Slack are leaders, they are accountable for the success of the team. Product engineers operate at any layer of the stack but prefer to work closer to what the user sees & interacts with. Candidates should have an eye for the alluring iOS design our users expect and an attention to detail down to the very last density independent pixel. They should know their way around the View hierarchy and be eager to partner with Product and Design to craft efficient, performant, and delightful user experiences. They’ll like building for the long term and value patterns and structures that allow for maximum flexibility in a constantly evolving product.

Slack has a positive, diverse, and supportive culture; we look for people who are curious, inventive, and work to be a little better every single day. In our work together we aim to be smart, humble, hardworking and above all, collaborative.

What You Should Have:

• At least 6+ years of mobile engineering experience with an emphasis on technical leadership in medium to large teams. 

• A demonstrated track record of spotting issues in complex codebases and transforming them into successful, high-impact projects.

• An extensive understanding of iOS framework components and their respective lifecycles.

• Strong computer science fundamentals: data structures, algorithms and programming languages

• Experience working closely with product teams, designers, and other developers to create a truly delightful mobile experience

• Current and detailed knowledge of the capabilities of different iOS API levels

• Experience developing highly performant Swift/Objective-C code and view layouts and the ability to diagnose performance bottlenecks

• A disciplined approach to development, testing, documentation and code structure.

• Familiarity with the iOS tool ecosystem for development, testing, debugging, and performance benchmarking.

• An excellent understanding of best practices for concurrency and threading

• A constant desire to improve, learn more and take things higher

Bonus Points:

• Experience using Slack and a keen interest in making it better

• Experience with SwiftUI, Combine, or async/await

• Familiarity with iOS performance profiling tools (Instruments, Xcode profiler)

• A passion for building and maintaining great open source projects or otherwise contributing to the iOS community
