We are looking for a pragmatic full-stack engineer positioned at the nexus of product, growth, and operational automation. Your role is to diagnose difficult bugs quickly, write resilient Next.js/React code that withstands regression testing, and configure Firebase/GCP environments to ensure accurate attribution flows from Meta Pixel and Google Tags. The work you deliver will directly enhance conversion tracking and reduce manual overhead.
The objective is straightforward: maintain system integrity, ensure growth metrics are observable, and eliminate repetitive manual tasks through automation. We do not create infrastructure for the sake of complexity. Engineering connects directly to marketing and product objectives, enabling data-driven decisions through instrumented conversion funnels. This means consistent deployments, real-time performance visibility, dependable event tracking, and tight feedback cycles measured in days rather than weeks.
This position centers on building and sustaining. You are the engineer who secures the technical foundation while accelerating team productivity—deploying fixes promptly, creating reusable scripts for recurring QA scenarios, confirming changes through regression suites, and instrumenting user journeys so analytics remain accurate. If you are motivated by measurable outcomes, continuous learning, and transforming fragmented workflows into streamlined systems that the organization depends on, this responsibility is yours to take. Apply if you are prepared to own reliability, integrations, and the automation infrastructure that accelerates organizational progress.
