About the Team:
This team is responsible for the speed, stability, and operational health of HighLevel. We partner across Backend, SRE, Infrastructure, Messaging, CRM, and Automations teams to ensure the platform runs smoothly under unpredictable workloads and global traffic patterns.
Our mandate is to detect issues early, eliminate bottlenecks at the root, and build infrastructure that stays reliable years into the future.
About the Role:
We’re hiring a Senior Backend Engineer who is passionate about performance optimisation, distributed systems behaviour, runtime efficiency, and platform-level correctness. You won’t just tune endpoints—you’ll design systems and patterns that prevent slowness before it begins.
This is a hands-on engineering role with broad influence across services, architecture decisions, and operational standards. You will work with high-traffic systems, complex micro-services, and global workloads where milliseconds matter.
