We're seeking a full-stack engineer focused on the convergence of product operations, growth infrastructure, and workflow automation. If you can troubleshoot complex bugs efficiently, build maintainable Next.js/React components that pass rigorous regression testing, and configure Firebase/GCP to deliver accurate attribution signals from Meta Pixel and Google Tags, your contributions will directly enhance conversion tracking and reduce manual overhead.
Your mission is straightforward: maintain system stability, ensure the growth stack is measurable, and eliminate repetitive manual work through automation. We don't engineer systems for abstraction's sake. We connect engineering directly to marketing and product functions so that decisions rest on instrumented, data-driven funnels. This translates to stable deployments, real-time performance visibility, dependable tracking infrastructure, and rapid ship-to-impact cycles measured in days.
This role blends building with stewardship. You'll stabilize the foundation while accelerating team velocity—delivering fixes rapidly, creating reusable processes or scripts for recurring QA workflows, validating updates with regression coverage, and instrumenting user journeys so insights remain accurate. If you're energized by tangible impact, fast iteration, and the challenge of transforming fragmented pipelines into streamlined systems the organization depends on, take ownership. Apply if you're prepared to manage the reliability, integrations, and automation infrastructure that enables the rest of the company to execute faster.
