We are looking for a practical full-stack engineer positioned at the convergence of product, growth, and automation. If you can troubleshoot complex issues quickly, write maintainable Next.js/React code that passes regression testing, and configure Firebase/GCP to deliver accurate attribution data from Meta Pixel and Google Tags, your work will directly enhance conversion visibility and reduce operational overhead.
Your mission is straightforward: maintain system stability, ensure the growth engine is measurable, and eliminate manual work through automation. We do not build "platforms" as isolated exercises. We connect engineering directly to marketing and product so that instrumented funnels drive decisions. This means consistent releases, real-time performance data, dependable tracking, and fast ship-to-impact cycles measured in days.
This role centers on building and maintaining. You will be responsible for preserving the foundational integrity while accelerating delivery—deploying fixes efficiently, creating processes or scripts to address recurring QA needs, validating updates through regression tests, and instrumenting user journeys so insights remain accurate. If you are motivated by tangible impact, continuous learning, and the clarity of transforming a disorganized pipeline into a dependable system the entire team counts on, take ownership of this responsibility. Apply if you are prepared to manage the reliability, integrations, and automations that enable the organization to move with greater speed.
