## Description

We’re looking for a Senior Staff Engineer to help shape the future of Slack’s mobile product. As a Prototyping Engineer, you’ll embed as a leader on greenfield, zero-to-one initiatives. You’ll influence product and design direction through engineering work that builds and ships the first versions of newly-imagined, fully working product features.

Responsibilities:

- Shape the future of Slack on mobile by leading the engineering development of experiences used by millions of users every day, spanning multiple teams and the broader organization.

- Lead the most complex, ambiguous, cross-functional initiatives from early technical exploration through production rollout and long-term evolution.

- Lead feature prototyping to define the mobile user experience for Slack’s biggest opportunities.

- Partner closely with Product and Design to shape experiences that balance user needs, technical constraints, and long-term maintainability.

- Influence engineering decisions beyond your immediate team through technical leadership, product reviews, and mentorship.

- Set and evangelize best practices for mobile feature development and operational excellence across the broader engineering organization.

- Mentor senior engineers and contribute to the growth of the broader mobile engineering community within Slack.

Requirements:

- 10+ years of professional software engineering experience, including significant experience building complex, high-craft iOS applications at scale.

- Proven track record of moving outside of organizational boundaries to start new initiatives, prototype the path to production, and reorient the organization to support the new initiative.

- Experience working in fast-paced environments, whether at a start-up, in an incubator, or on a zero-to-one team inside a larger enterprise.

- Proven track record of leading large, ambiguous, org-spanning technical initiatives with significant business impact.

- Deep expertise in Swift framework and modern iOS development.

- Strong understanding of iOS architecture, application lifecycle, concurrency, networking, and performance optimization.

- Demonstrated ability to influence product and technical direction through expertise and collaboration, driving alignment across executive stakeholders, Engineering/Product/Design leadership, and multiple teams.

- A bias toward ownership, execution, and continuous improvement, with the judgment to prioritize the highest-leverage work across the organization.

Preferred Qualifications:

- Experience with Combine, Swift Concurrency (async/await, actors), and dependency injection frameworks (e.g. Needle, Resolver).

- Experience leading large-scale new products, features, or product transformations spanning multiple teams or the whole org.

- Experience using research, usability testing, data, and experimentation to ground decisions and uncover opportunities.

- Contributions to open source projects or the iOS community, or other external recognition of technical leadership.

- Experience building collaboration, productivity, messaging, AI, or enterprise software products.

- Excellent communication skills.

- Strong product intuition and a passion for creating exceptional user experiences.

Benefits:
