About the Role

We’re looking for a Senior Software Engineer to join our Agency Module and Billing Team, which powers the foundation of our Agency Ecosystem — enabling seamless onboarding, management, and monetisation experiences for HighLevel’s agencies and their clients.

Today, over 100K agencies run their businesses with HighLevel, collectively serving 2M+ businesses of all scales — primarily SMBs. The Company Module and Agency Billing systems are at the heart of this growth, helping agencies onboard faster, manage finances effortlessly, and scale their operations with reliability and transparency.

This team builds and scales key components like Agency Signup, Agency Billing, and the HighLevel Affiliate Program, all integrated into our whitelabeled platform that empowers businesses to deliver customised experiences under their own brand. These systems are critical to the growth and sustainability of HighLevel’s ecosystem — supporting thousands of agencies and their downstream customers with robust, scalable, and secure infrastructure.

As a Senior Software Engineer, you’ll play a pivotal role in designing and evolving these core systems. You’ll work on challenges across frontend and backend architecture, distributed systems, payment integrations, and multi-tenant SaaS design — ensuring reliability, scalability, and a seamless experience for agencies across web and mobile platforms.

You’ll collaborate closely with Product Managers, Designers, and other Engineers to deliver powerful and intuitive solutions that help agencies scale faster and manage their businesses effortlessly.

• Collaborate cross-functionally with Product Managers, Designers, and other Engineering teams to ensure alignment between business goals and technical architecture.
• Participate in technical reviews, deep dives, and on-call rotations, fostering a culture of accountability, operational excellence, and continuous improvement.

Requirements

• Strong backend engineering and distributed system design skills, with hands-on experience in API development, data modeling, and systems architecture using Node.js (NestJS preferred), TypeScript, PostgreSQL, MongoDB, and Redis.
• Expertise in backend performance optimization, caching strategies, and event-driven architectures (e.g., Redis, Kafka, Pub/Sub).
• Familiar with modern frontend frameworks (React, Vue, Angular), advanced UI engineering patterns, and CSS libraries like Bootstrap or Tailwind CSS.
• Advanced experience with complex state management libraries (e.g., Redux, Vuex, MobX) and architectural design of large-scale application state.
• Proven track record of optimizing frontend performance and web vitals at scale, including experience with server-side rendering (SSR), edge, or hybrid rendering architectures.
• Familiarity with frontend and backend observability - including monitoring, tracing, error tracking, and performance profiling in production (e.g., Grafana, Prometheus, Sentry, PostHog).
• Strong understanding of security best practices across the full stack—including authentication, authorization, access control, secure data flow, and privacy compliance.
• Excellent communication and cross-functional collaboration skills, able to drive complex initiatives, lead technical discussions, and mentor junior engineers.
