5 Questions to Ask Before Hiring a Slack Developer

Slack has become a cornerstone of modern workplace communication, enabling teams to collaborate seamlessly across projects and departments. But to unlock Slack’s full potential, many companies turn to custom Slack apps and integrations tailored to their unique workflows.

If you’re planning to hire a Slack developer to build or enhance your Slack workspace, it’s crucial to ask the right questions upfront. The right developer can transform your team’s productivity, while the wrong hire can lead to wasted time and resources.

Here are 5 essential questions to ask before hiring a Slack developer:

1. What Experience Do You Have with Slack API and Bolt SDK?

Slack development is a niche skill. It’s important that your developer has hands-on experience with Slack’s APIs, particularly the Slack Bolt SDK, which simplifies app building in Node.js and Python.

Ask them to describe projects where they:

  • Built slash commands, interactive messages, or modals
     
  • Worked with Slack Events API or Socket Mode
     
  • Managed OAuth flows for multi-workspace installation
     

Experience with these tools ensures they understand Slack’s event-driven architecture and can deliver reliable, scalable apps.

2. How Do You Approach User Authentication and Security in Slack Apps?

Slack apps often require OAuth 2.0 authentication, handling sensitive tokens and permissions.

A solid Slack developer should:

  • Explain how they implement secure OAuth flows
     
  • Describe token management and storage best practices
     
  • Be aware of Slack’s permission scopes and requesting only what’s necessary
     

Security is paramount to protect your workspace data and maintain user trust.

3. Can You Share Examples of Slack Apps or Integrations You’ve Built?

Seeing concrete examples or demos of previous work is one of the best ways to gauge a developer’s capabilities.

Look for:

  • Apps with intuitive user interfaces using Slack’s Block Kit UI framework
     
  • Smooth handling of real-time events and interactions
     
  • Integration with third-party APIs or internal systems relevant to your needs
     

A portfolio demonstrates their problem-solving skills and creativity within Slack’s ecosystem.

4. How Do You Handle Rate Limits and Slack API Constraints?

Slack imposes API rate limits to ensure fair usage. Developers need strategies to avoid hitting these limits, which can cause app failures.

Ask about their experience with:

  • Efficient event processing and batching requests
     
  • Implementing retry logic with exponential backoff
     
  • Using Socket Mode to reduce API call volume
     

Understanding rate limits ensures your Slack app runs smoothly even at scale.

5. What’s Your Development and Deployment Workflow?

Building a Slack app isn’t just about coding; it involves testing, deployment, and maintenance.

Inquire about:

  • Their use of version control and collaboration tools (e.g., Git)
     
  • Testing strategies for Slack interactions and edge cases
     
  • Deployment platforms (e.g., AWS Lambda, Heroku, serverless)
     
  • Monitoring and logging to track app performance and errors
     

A professional approach to the entire lifecycle leads to higher quality and easier future updates.
