Our teams are strong at building and scaling products. Every service has an owner, every feature has engineers behind it, and every database has deep expertise. What we need now is someone who can look across all of them — someone who understands how the entire distributed system works together and can identify risks that may not be visible within an individual service.
A retry policy in one service, combined with a queue configuration several hops downstream, can become a cascading failure under peak load. Your role is to identify those risks before they reach production.
You’ll start with Workflows, HighLevel’s automation engine and one of the largest systems in the company. It handles 3.1 billion enrollments and 21.5 billion action executions every month, with traffic peaking at 28,000+ requests per second. The platform runs across thousands of pods on GCP and uses Pub/Sub, Cloud Tasks, Redis, and multiple database engines.
From there, your scope will expand into Conversations, which processes 2.6 billion messages every month, as well as our new Ticketing platform. With Ticketing, you’ll have the opportunity to influence the architecture early — building resilience and scalability into the system from the start rather than addressing them later.
This is not a traditional architect role where you design systems and hand them over for implementation. It is also not a feature-focused engineering role with a defined product backlog.
This role sits across systems and teams, with a clear mandate: understand how the platform behaves as a whole, identify systemic risks, and make sure our architecture can continue to scale reliably.
