Figma DevOps / SRE Interview Questions

1.Tell me about a time you built monitoring or alerting that had to be understandable by people outside your immediate team. What did you build and how did you make it accessible?

2.Walk me through a time you simplified a complex deployment or infrastructure process to make it more accessible to product engineers. What was complex about it originally?

3.Walk me through a time you spent extra effort polishing an automation or deployment process that most people would consider 'good enough.' What drove you to invest that additional time?

4.Tell me about the last time you had to give direct feedback to a teammate about their infrastructure work or operational practices. What was the situation and how did you approach it?

5.Describe the most complex incident you've handled involving real-time system failures or race conditions. What was failing and how did you debug it?

6.Describe a monitoring, alerting, or automation system you built where you went beyond the basic requirements to create something truly elegant. What made you push for that extra level of quality?

7.Design a backup and disaster recovery strategy for Figma's PostgreSQL database that stores design files and user data. What are your key considerations?

8.Figma runs on AWS across multiple regions. How would you set up monitoring to detect and alert on issues that could impact our collaborative editing experience before users notice them?

9.Figma's real-time collaboration engine uses WebSockets to sync millions of document operations across users. If you noticed WebSocket connections dropping frequently during peak hours, how would you investigate and resolve this?

10.Our Redis cluster is approaching memory limits and we're seeing increased latency in document loading. Walk me through your approach to scaling this without impacting user experience.

11.You need to deploy a Kubernetes cluster update across our production environment that serves millions of design files. How do you ensure zero downtime for active collaborative editing sessions?

12.You're setting up CI/CD pipelines for Figma's WebAssembly rendering engine written in C++ and Rust. What are the unique challenges and how would you address them?

13.Design the asset delivery system for Figma Design that needs to serve millions of design files with images, fonts, and vector graphics to users worldwide. How would you ensure fast loading times while handling real-time updates?

14.Figma needs to implement auto-scaling for the rendering cluster that processes design exports and thumbnail generation. Design a system that can handle sudden spikes when large teams batch-export their design systems while maintaining cost efficiency during low usage periods.

15.You're designing the infrastructure to support FigJam's whiteboard sessions that can have hundreds of concurrent users adding sticky notes, drawings, and reactions. How would you architect the backend to handle this real-time collaboration?

16.Design the build and deployment pipeline for Figma's browser-based application that includes TypeScript, WebAssembly modules, and real-time collaboration features. The system needs to support multiple daily deployments while ensuring zero downtime for active design sessions.

17.Design the logging and observability system for Figma's real-time collaboration engine that processes millions of operations per minute. The system needs to help engineers debug complex race conditions and operational conflicts while being accessible to product teams investigating user-reported issues.

18.Design a global traffic routing and failover system for Figma that ensures users can continue collaborative editing even when entire AWS regions become unavailable. The system must handle ongoing real-time sessions gracefully while maintaining data consistency across regions.

19.Tell me about a time you had to champion an infrastructure change that required buy-in from product engineers who didn't see the immediate value. How did you get them on board?

20.Describe a time when you mentored someone on infrastructure or operational practices. What did you teach them and how did you ensure they actually learned it?

21.Walk me through a time you had to coordinate a complex infrastructure project across multiple teams who had conflicting priorities. How did you navigate those tensions?

22.Tell me about an incident where you had to lead a post-mortem for a service outage that affected multiple teams. How did you ensure it was blameless and actually led to improvements?

23.Describe the most challenging time you've had to influence a senior engineer or architect to change their approach to infrastructure or operational practices. What made it difficult and how did you succeed?

24.Tell me about a time you had to make a decision that would improve system reliability but negatively impact developer velocity in the short term. How did you navigate that tradeoff and get team buy-in?

25.Our design system team uploads 500 new component variants to Figma each week, but designers report it takes 3-4 seconds to see updates in their files. Estimate how much server compute cost we could save if we reduced this to 1 second through better caching.

26.FigJam usage has grown 300% this quarter, but our infrastructure costs only increased 150%. The finance team wants to understand this efficiency gain and whether it's sustainable. Walk me through how you'd analyze this.

27.A product team reports that 15% of users can't access their Figma files during peak hours, but our overall error rates look normal. How would you investigate this discrepancy and identify the root cause?

28.Design Mode, Dev Mode, and FigJam all use different backend services but share user session data. If we're seeing inconsistent user state across products, how would you design a debugging framework to identify where state divergence occurs?

29.Figma processes 50 million collaborative editing operations per day. If we wanted to enable 'time travel' debugging where users can see their file at any point in the last 30 days, estimate the storage and compute costs for this feature.

30.Our WebAssembly rendering engine occasionally crashes browser tabs for users with complex design files containing 10,000+ elements. The crashes happen inconsistently and we can't reproduce them locally. How would you build a system to capture debugging information from these production crashes?
