Software Development Engineer - Backend (Builder)

HighLevel is an AI-powered business operating system that gives agencies, entrepreneurs and SMBs the infrastructure to build, automate and scale. We are seeking an SDE-3 Backend Builder to own the CRM Opportunities product end-to-end.

Requirements

• 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
