We're looking for a Software Development Engineer III (Full Stack) to join our Labs team. Labs is the platform that powers how HighLevel ships new features to production — controlling staged rollouts, feature flags, and experimentation across the platform, and closing the loop with in-product customer feedback.
Today, every new capability shipped across HighLevel's platform passes through Labs' feature-flag and rollout infrastructure, spanning 100K+ agencies and the 2M+ businesses they serve. The systems we build directly shape how safely and quickly the rest of the engineering org can ship — enabling gradual rollouts, targeted enablement at the company and location level, and fast, safe rollback when something goes wrong.
The team builds and scales core capabilities across feature flag management, staged feature rollout, and customer feedback collection. These systems let product and engineering teams control exactly who gets a feature and when, monitor adoption and health in real time, and gather structured feedback directly from agencies and locations to inform what ships next.
As an SDE-3, you'll play a key role in building and evolving these systems across the frontend and backend, while contributing to technical architecture and engineering decisions. You'll work on challenges involving high-throughput flag evaluation, scalable APIs and services, distributed systems, and data architecture — with a strong focus on reliability, low latency, and correctness, since every other team's shipping velocity depends on this platform working correctly.
You'll collaborate closely with Product Managers, Designers, and other Engineers across the org to take features from requirements and technical planning through implementation and production, while contributing to technical decisions and continuously improving the systems you own.
