HighLevel - Lead Software Engineer - Full Stack Development

We're looking for a Lead Software Engineer to join our Funnel and Website Builder team, the group behind one of HighLevel's most heavily used and business-critical product surfaces. The Builder ecosystem powers the end-to-end experience for creating funnels and websites: real-time collaborative editing, rendering, publishing, analytics, AI-assisted creation, and global delivery at scale.

As a Lead Engineer, you will balance technical leadership with team leadership, spending roughly 50% of your time managing and guiding engineers, driving execution, and ensuring alignment and the remaining 50% contributing hands-on to building impactful features, improving architecture, and elevating code quality. You will steward delivery across multiple squads in the Builder ecosystem, partnering closely with product, design, infra, and security teams. You'll ensure smooth sprint execution, maintain engineering excellence, remove blockers, guide architects and developers, and ensure the direction of the product is technically sound, scalable, and stable. This is a highly visible leadership role responsible for both people outcomes and product outcomes.

• Prototype and ship enhancements to the rendering engine, builder UX, theme system, component framework, publishing flows, or AI-powered creation features.
• Debug complex production issues across distributed microservices, CDN layers, and global traffic patterns.
• Improve developer experience through better tooling, automation, and build pipelines.
• Manage and mentor developers across Builder squads, including performance management, career growth, and technical guidance.
• Lead and facilitate sprint planning, sprint creation, execution tracking, and sprint reporting.
• Work with PMs, designers, and engineering managers to translate roadmap goals into executable sprint plans.
• Review team deliverables and ensure engineering direction is consistent, maintainable, and aligned with long-term platform strategy.
• Conduct code reviews, provide constructive feedback, and set quality standards across teams.
• Ensure team velocity remains high, proactively identify blockers, resource gaps, or architectural misalignment.
• Encourage a culture of ownership, iterative execution, and engineering excellence.
• Collaborate with cross-functional partners to refine roadmap, prioritise work, and ensure predictable delivery.
