About the Role:
We’re looking for a Lead Software Engineer with deep expertise in Node.js, MongoDB, EKL stack and distributed systems, combined with a strong focus on platform stability, scalability, reliability, and long-term technical excellence. You’ll be joining our LC Email Platform team, which builds and maintains core capabilities such as Emails messaging, Email Verification, Dedicated Domains and IPs, Warmup Tool, Email Inbox, and platform integrations that power communication for thousands of businesses.
Our Email platform currently processes over 1.5 Billion messages per month, and we are on a strategic journey to scale this to 4 Billion messages per month, aiming to become the leading BSP(Business Service Provider) in the industry. Similarly, our platform supports 450K+ active businesses using our email services, and we’re aggressively scaling this to 1 Million+ users as we expand our global footprint. This growth trajectory demands a leader who can architect highly scalable systems, anticipate platform bottlenecks, and design infrastructure capable of supporting massive scale with predictable performance.
This role requires someone who is comfortable working on high-scale, mission-critical platform components. You’ll take ownership of challenges related to system stability, performance optimization, distributed architecture improvements, operational efficiency, cost management, and security hardening across our Email infrastructure. You will drive architectural decisions, lead complex problem solving, reduce long-standing tech debt, and ensure our services remain resilient, observable, and compliant with various Email Service Providers (ESP) requirements.
As a technical leader, you will collaborate closely with product, infrastructure, and cross-functional engineering teams to design robust APIs, improve end-to-end delivery pipelines, enhance monitoring and alerting, streamline platform operations, and shape the long-term technical roadmap for the entire Email ecosystem within HighLevel. You will play a pivotal role in scaling our platform to the next order of magnitude while delivering exceptional reliability and performance for our global customer base.
