Senior SDE - Platform

About the role

We’re hiring a Senior Full Stack Engineer to design, build, and scale the backend systems and frontend interfaces that power the Threads & Composer experience inside HighLevel Conversations. You’ll spend most of your time on backend and API design, data flows, and performance — while still owning the Vue 3 UI layer end-to-end.

What you'll do

• Design and build the platform components Workflows and Conversations run on, queueing pipelines, storage access layers, caching strategies, rate limiters, schedulers
• Own your components end to end: architecture, design docs, code, tests, rollout, dashboards, and production health
• Go deep on data stores at scale , schema and index design, sharding strategies, replication behavior, and migrations on live systems with billions of records
• Work close to the infrastructure : GKE autoscaling, resource tuning, Pub/Sub and Cloud Tasks topologies, and the capacity planning that keeps headroom ahead of growth
• Debug the incidents that cross layers, where the answer isn't in one service's logs but in how the pieces interact

What you need

• 4–7 years in software engineering
• Node.js
• SQL
• Data structures
• Go
• Redis
• Kafka
• Any graduate

Good to have

• Kubernetes
• GCP
• TypeScript
• RabbitMQ
• NoSQL
• Test cases
