# Scaling the Linear Sync Engine

Source: https://linear.app/blog/scaling-the-linear-sync-engine

## Summary

Linear's engineering team has recorded a follow-up talk on how its realtime sync engine works and how it has scaled. The talk covers the challenges the team has faced in scaling the engine, how the API around it developed in response, and how the engine works in the Linear application today. It is a sequel to an earlier talk the presenter gave at React Helsinki, and it was recorded at the company offsite a few weeks before the post. The post also invites readers to try the sync engine by signing up for a free Linear account and notes that the company is hiring across Europe and North America.

How does Linear’s realtime sync engine work behind the scenes? In this talk, I cover the challenges we’ve had scaling the sync engine, how the API around it has formed because of those challenges, and how the sync engine works in the Linear application today.

A few years ago, I gave a talk at React Helsinki about how the Linear realtime sync engine works behind the scenes.

We have come a long way since then, so we recorded a sequel to that talk at our company offsite a few weeks ago. In this video we cover the challenges we’ve had scaling the sync engine, how the API around it has formed because of those challenges, and how the sync engine works in the Linear application today.

If you want to experience the sync engine in action, you can sign up for a Linear account (it’s free!) and test it yourself.

Interested in helping us scale the sync engine (and Linear) to the next level? We are hiring for a variety of roles across Europe and North America.
