Job Category Software Engineering Job Details About Salesforce Salesforce is the #1 AI CRM, where humans with agents drive customer success together. Here, ambition meets action. Tech meets trust. And innovation isn’t a buzzword — it’s a way of life. 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. Ready to level-up your career at the company leading workforce transformation in the agentic era? You’re in the right place! Agentforce is the future of AI, and you are the future of Salesforce. The Experience We're looking for an engineering leader to own the shared technical foundations of Slack's clients. As Senior Director of Engineering for the Application Architecture and Systems pillar, you will lead the organization responsible for Slack's product infrastructure. That includes shared client infrastructure, frameworks, accessibility, APIs and components on web, Slack desktop through our Electron app, and Android and iOS mobile. The work is technically challenging and high stakes. These foundations directly impact the quality of the experience for every one of Slack’s millions of users. Your org will set the bar for client performance, reliability, quality, and feature velocity in the era of agentic coding. You will lead a large, multi-disciplinary organization of 50+ people, including managers. You will partner closely with Product and Design to set an ambitious strategy.

Partner with your Product counterparts to set ambitious strategy and make clear tradeoffs. • Raise the bar on engineering excellence — Establish high standards for performance, reliability, quality, and craft in the team's work and culture. • Evolve development for the agentic era — Reshape how client engineering teams build and ship so they can move faster without sacrificing quality, including with AI coding agents. • Own shared platforms — Steward the frameworks, components, design-system foundations, and internal client APIs that every Slack product team depends on. • Champion accessibility — Make accessibility a first-class part of how Slack is built. • Partner across the company — Collaborate with executive peers in Product, Design, and Engineering across Slack and Salesforce to align priorities and resolve dependencies. • Build a connected, global team — Unite a distributed, hybrid organization into a cohesive, high-performing culture. • Up-level team performance — In your first 60–90 days, assess the org, set strategy, and raise technical excellence and team performance. You're Our Person If... • You have significant experience leading product infrastructure engineering at a company with a complex, large-scale client application. • You have experience in client infrastructure. Web and mobile are both a plus, but more depth in one is fine. • You have a track record leading large engineering organizations, including managing managers and coaching senior leaders. • You can set technical strategy and work with Produc
