Senior Backend SDE – CRM Opportunities (Remote)

HighLevel; United States; Remote; USD 140,000 - 190,000; Full time

Job summary

HighLevel, a US-based AI-powered business operating system, is seeking an SDE-3 Backend Builder to own the CRM Opportunities product end-to-end. You will design data models, APIs, and distributed workflows powering pipelines and automations at scale.

You will work with Node.js or Go, Kubernetes-style scaling, multi-tenant SaaS, and occasionally ship Vue UI surfaces. You’ll be responsible for reliability, instrumentation, and incident responses in a high-traffic product.

Qualifications

• 4+ years building and operating production backend systems at scale.
• Strong fundamentals in data modeling (SQL and NoSQL), API design, and distributed systems.
• Hands-on experience with Node.js or Go in production.
• Track record of owning services end-to-end — design, build, deploy, on-call.
• Comfort working independently in ambiguous problem spaces with high ownership.
• Solid grasp of scalability, performance, and reliability trade-offs.
• Experience building CRM, sales, pipeline, or workflow products.
• Worked on multi-tenant SaaS at scale (sharding, tenant isolation, fair-use limits).
• Familiarity with event streaming (Kafka/Redis Streams), queues, and async processing.
• Exposure to MongoDB, Postgres, Elasticsearch, ClickHouse, or similar at non-trivial scale.
• Frontend fluency in Vue.js — enough to ship a feature without a frontend partner
• Strong product instincts and a portfolio or GitHub of shipped work

Responsibilities

• Own the full lifecycle of Opportunities backend: translate business and customer needs into scalable, production-grade services.
• Design and evolve the data model for pipelines, stages, deals, and associated entities — getting consistency, throughput, and query patterns right
• Build and scale APIs, event-driven workflows, and background jobs that handle high-volume writes, automations, and integrations
• Tackle distributed systems concerns: idempotency, eventual consistency, race conditions, hot tenants, and noisy-neighbor isolation
• Improve performance and reliability of large pipelines (millions of opportunities per workspace) through indexing, sharding, caching, and query optimization
• Ship end-to-end when needed — including UI changes in Vue — without blocking on cross-functional handoffs
• Instrument the system: logs, metrics, traces, and SLOs that make production behavior legible
• Drive incident response, postmortems, and the engineering hygiene that keeps a high-traffic product healthy
