About the Role
- We’re looking for a Lead Software Engineer with deep expertise in Node.js, MongoDB, and modern frontend frameworks, along with a bold vision for how AI-assisted development can accelerate engineering workflows.

- As a Lead Engineer, you’ll own architectural decisions and solve deep product-platform problems around high-performance snapshot cloning, rollback systems, and version management. You’ll collaborate across product, infra, and platform teams while mentoring engineers and driving the long-term roadmap for one of HighLevel’s most strategic surface areas. If you enjoy building technically rigorous systems that scale, this team is where your work will have immediate and visible impact.

- Strong experience with relational and NoSQL data models (especially with complex temporal data)
- Experience with modern front-end frameworks (e.g., React, Vue, Angular) and building full-stack web applications.Proven track record of architecting complex systems and delivering scalable, high-performance web apps in production.
- Strong understanding of software design patterns, API design, and microservices architecture in a multi-tenant environment.
- Skilled in guiding technical architecture, making high-impact engineering decisions, and mentoring fellow engineers.Experience with code quality practices, automated testing, CI/CD pipelines, and dev tooling optimization.Excellent problem-solving skills, with clear and collaborative communication across cross-functional teams.
