How Slack accelerates engineering learning with PlusPlus
1,000+
Unique presenters contributing to onboarding and skill programs
70+
More than 70 unique presenters for onboarding programs. New hires get to meet a diverse range of employees.
At Slack, part of Salesforce, building a scalable, engaging learning experience for its rapidly growing engineering team was a top priority. PlusPlus became the learning platform of choice to support onboarding and continuous skill development across the organization. By leveraging the flexibility and collaborative features of PlusPlus, Slack’s technical program leadership successfully transformed its traditional training model into a more interactive and data-driven engineering learning ecosystem.
What were the key challenges?
Slack’s engineering hiring and growth outpaced its existing learning infrastructure. Traditional training methods lacked the engagement and structure required to effectively onboard new engineers or develop their skills over time. The team also faced difficulty creating content that engineers would actively engage with and measurable ways to assess real learning impact. Scaling these efforts without centralized tools and insights made it harder to achieve consistency and continuous improvement across programs.
What approach worked?
Slack turned to PlusPlus to redesign its training approach with a people-centric, outcome-oriented learning strategy. With PlusPlus, Slack’s technical program manager, Benji Shine, built structured learning Tracks that guided engineers through logical progressions of skills. Detailed Assessments and Codelabs ensured engineers had truly acquired key competencies, while real-time Surveys provided continuous learner feedback to refine content. By combining structured pathways with data insights, Slack established a more engaging, iterative learning model where engineers could grow with purpose and support.
“From my point of view, the goal of engineering learning is to make the business more successful. And to me, that comes from helping the engineers become better at their jobs. PlusPlus made it easy to export and analyze presenter participation across onboarding, a single report gave me exactly what I needed.”
