REQUIREMENTS - 5+ years of experience building and shipping data-intensive production web applications, with substantial hands-on responsibility across frontend and backend development. - A proven track record as a primary technical driver at a fast-growing startup. - Strong React, TypeScript, and frontend engineering skills. - Strong backend engineering skills, including API design, service architecture, caching, asynchronous processing, and integrating external systems. - Hands-on data engineering experience, including building, deploying, and maintaining production ETL/ELT pipelines. - Strong SQL and data modeling skills, with experience preparing and serving large datasets for analytical workloads. - Demonstrated ability to diagnose and improve performance across the stack. - Experience deploying and operating applications and data pipelines in a cloud environment, including CI/CD, automated testing, containerization, logging, monitoring, and production debugging. - Strong product judgment, clear communication, and proactive ownership. WHY JOIN US At Brandlight, you’ll build and shape a new category at the intersection of AI, marketing, and commerce. We’re a fast-growing startup led by repeat entrepreneurs, world-class engineers, and marketing leaders, all driven to reinvent how brands are built, discovered, and chosen in the age of AI.
