About Slack

Slack (Salesforce Company) is on a mission to make your working life simpler, more pleasant and more productive. Culture is the north star that guides how we work together and with our customers. Are you looking to build something greater than yourself? Do you want to work alongside some of the most dynamic people in the industry? If so, Slack just might be the place for you.

Slack has a positive, diverse, and encouraging 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.

About the Role

Senior Onboarding Specialists are the first technical partners for our most strategic and complex Slack Premier and Signature customers. We help them hit the ground running by building a strong product foundation, achieving early wins, and setting the stage for long-term success on Slack and the broader Salesforce platforms.

We act as trusted advisors during the onboarding phase, guiding customers through pre-implementation readiness, leading cross-functional collaboration, and driving consistency across the onboarding practice. Your work will directly shape the customer experience at scale—setting the standard for long-term engagement and success. By delivering outstanding value in the initial stages of the customer's journey, you will contribute to our customers' success, influence the evolution of our onboarding programs, and reinforce Salesforce's reputation as an industry leader.

Your Impact

Lead Strategic Customer Onboarding: Serve as the senior point of contact for our most complex and high-value customers. You'll design and lead discovery engagements, develop sophisticated onboarding frameworks, and ensure seamless coordination across sales, implementation, and customer success teams.

Accelerate Adoption at Scale: Drive customers to value faster by identifying systemic adoption gaps, recommending high-impact feature strategies, and building scalable success plans. You'll own and influence key metrics like time to production, feature adoption rates, and integration reliability across your portfolio.

Own Complex Migrations: Lead customers through enterprise plan migrations including SSO, Grid/Enterprise+ prerequisites, and deeply complex integration or API challenges. You'll serve as the senior technical escalation point and set the bar for thoroughness and velocity.

Champion and Evolve Best Practices: Synthesize patterns across customer engagements to develop new playbooks, training materials, and scaled programs. You'll proactively shape the onboarding methodology and serve as a thought leader both internally and externally.

Mentor and Develop the Team: Coach and support junior Onboarding Specialists, share knowledge across the team, and contribute to the overall excellence of the Customer Success practice.
