We operate at the intersection of product innovation, mobile platform excellence, and large-scale engineering. The systems we build support millions of daily users and require deep investments in performance, reliability, accessibility, and user experience.

We're looking for a Staff Android Engineer to help shape the future of productivity on mobile. As a Staff Engineer, you'll serve as a technical leader across multiple teams and initiatives. You'll drive architecture and engineering strategy, influence product direction, and help solve some of the most challenging technical problems in Slack's Android application.

You'll work closely with Product, Design, Backend, Infrastructure, iOS, and fellow mobile engineers to deliver experiences that are intuitive, performant, and reliable for millions of users worldwide. This role combines hands-on technical leadership with broad organizational influence.

• Shape the future of productivity on mobile by leading the architecture and technical strategy behind experiences used by millions of Slack users every day.
• Lead complex, cross-functional initiatives from early technical exploration through production rollout and long-term evolution.
• Partner closely with Product and Design to shape experiences that balance user needs, technical constraints, and long-term maintainability.
• Identify platform-wide opportunities to improve performance, reliability, accessibility, and developer productivity.
• Influence engineering decisions beyond your immediate team through technical leadership, design reviews, and mentorship.
• Establish best practices for Android development, testing, observability, and operational excellence.
• Help evolve Slack's mobile architecture and infrastructure to support future product investments, including AI-powered experiences.
• Mentor senior engineers and contribute to the growth of the broader Android engineering community within Slack.

• Proven track record of leading large, ambiguous technical initiatives with measurable business impact.
• Experience designing systems and architectures that scale across multiple teams and long-lived codebases.
• Ability to influence technical direction through collaboration rather than authority and drive alignment across diverse stakeholders.
• 6+ years of professional software engineering experience, including significant experience building Android applications at scale.
• Deep expertise in Kotlin and modern Android development.
• Strong understanding of Android architecture, application lifecycle, concurrency, networking, and performance optimization.
• Strong product intuition and a passion for creating exceptional user experiences.
• Excellent communication skills and experience working across Engineering, Product, and Design organizations.
• A bias toward ownership, execution, and continuous improvement.

• Experience with Jetpack Compose and modern Android architecture patterns.
• Experience building shared platforms, design systems, or developer infrastructure.
• Expertise in application performance, startup optimization, reliability, and observability.
• Experience leading technical migrations or large-scale architectural transformations.
• Contributions to open source projects or the Android community.
• Experience building collaboration, productivity, messaging, AI, or enterprise software products.

You'll have the opportunity to influence the direction of Slack's mobile platform, shape experiences used by millions of people, and work alongside some of the strongest mobile engineers in the industry. You'll help define how work gets done on mobile in an increasingly AI-powered world.
