Lead Fullstack Engineer

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.

Responsibilities:

• Contribute directly to codebases across Vue 3 Nuxt, Module Federation, Node.js / NestJS services, and supporting infrastructure.
• Architecture and System Design: Design and review architectures for scalable, low-latency, high-traffic systems, including CDN and global traffic routing strategies.
• Routing and publishing servers; caching and edge rendering layers; real-time collaborative editing pipelines.
• Stability and performance instrumentation.
• Lead architectural discussions and help teams make informed technical decisions.
• Identify stability risks, performance bottlenecks, and systemic reliability gaps and drive targeted initiatives to eliminate them.
• Work with infra/SRE teams to ensure systems meet global-scale requirements across millions of daily page loads.
• Define architectural guardrails, standards, and best practices for frontend and backend services.
• Build impactful product features, performance improvements, and internal tooling.
• 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, and 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 the roadmap, prioritize work, and ensure predictable delivery.

Requirements:

• 7+ years of full-stack engineering experience building high-scale backend systems and complex UI platforms.
• Strong experience with Vue 3 Nuxt, Module Federation, and component-driven frontend architectures.
• Solid backend skills with Node.js, NestJS, event-driven systems, queues, and high-throughput APIs.
• Experience working with MongoDB, Firestore, Elasticsearch, ClickHouse, Nginx, CDN strategies, and multi-region deployments.
• Caching systems, distributed architectures, proxy servers. Strong understanding of real-time collaboration, rendering engines, asynchronous processing, and fault-tolerant design.
• Ability to design systems prioritizing reliability, maintainability, extensibility, and performance.
• Experience improving availability, stability, and responsiveness of large-scale production systems.
• Comfortable defining and working with SLOs, structured logging, distributed tracing, and performance dashboards.
• Strong debugging skills across frontend, backend, infrastructure, and distributed network layers.
• Proven experience leading engineers or squads, including mentorship and technical guidance.
• Ability to drive sprint execution, reporting, stakeholder communication, and predictable delivery.
• Excellent communication and ability to influence without authority.
• Collaborative, pragmatic, and solution-oriented mindset.
• Thrives in fast-paced environments with high product usage and large-scale impact.
