About the Role:
Channels are the gateway to the entire platform. We integrate with third-party messaging APIs — some flaky, some rate-limited, all critical.
You’ll own backend-heavy, full-stack systems that deliver reliable, scalable, real-time messaging across vendors like Meta, Apple, and others. This role blends distributed systems, deep API integration work, and UI scaffolding to help users manage conversations without friction.
Requirements:
- 5+ years of backend-heavy full-stack experience
- Deep knowledge of Node.js, TypeScript, and scalable service design
- Strong frontend ability with Vue.js, Vuex/Pinia, and component patterns
- Experience integrating third-party APIs (esp. messaging, comms, SaaS vendors)
- Familiarity with Kubernetes, GCP, Pub/Sub, Cloud Tasks, and event-driven infra
- Real-world experience with distributed systems, retries, timeouts, and async workflows
- Strong system design, communication, and mentoring skills
Responsibilities:
- Architect end-to-end systems to support new messaging channels (e.g. Apple Messages, Rich Media, DM APIs)
- Build abstractions for vendor APIs — handling auth, webhooks, retries, rate limits, and schema drift
- Design scalable job orchestration pipelines using Node.js, Pub/Sub, Cloud Tasks, and event-driven flows
- Structure UI components and frontend flows in Vue.js, with clean state and modular logic
- Define data models, write performant queries, and optimize access patterns across MongoDB, Firestore, ElasticSearch, ClickHouse
- Lead cross-functional delivery with SRE, Product, and Design
- Set engineering standards across system design, testing, and observability
- Mentor engineers and contribute to hiring and technical direction
EEO Statement:
At HighLevel, we value diversity. In fact, we understand it makes our organisation stronger. We are committed to inclusive hiring/promotion practices that evaluate skill sets, abilities, and qualifications without regard to any characteristic unrelated to performing the job at the highest level. Our objective is to foster an environment where really talented employees from all walks of life can be their true and whole selves, cherished and welcomed for their differences while providing excellent service to our clients and learning from one another along the way! Reasonable accommodations may be made to enable individuals with disabilities to perform essential functions.
