We are looking for a practical full-stack engineer positioned at the nexus of product development, growth initiatives, and process automation. Your ability to resolve complex technical issues efficiently, implement robust Next.js/React solutions that withstand rigorous regression testing, and configure Firebase/GCP infrastructure while ensuring accurate attribution data flows from Meta Pixel and Google Tags will deliver immediate improvements to conversion analytics and significantly reduce manual workload.
Your mission is straightforward: maintain system stability, ensure growth mechanisms are fully measurable, and eliminate repetitive manual tasks through automation. We do not construct "platforms" as standalone exercises. Engineering connects directly to marketing and product operations, enabling data-informed decisions through instrumented conversion funnels. This translates to dependable deployments, live performance metrics, trustworthy event tracking, and rapid build-to-impact cycles completed within days.
This position centers on building and maintaining critical systems. You will serve as the engineer who preserves foundational stability while accelerating team velocity—delivering rapid bug fixes, creating reusable processes or scripts for recurring QA requirements, confirming updates through regression validation, and instrumenting user flows to ensure insights remain consistently accurate. If you are energized by tangible impact, accelerated learning, and the reward of transforming chaotic workflows into dependable systems the entire organization counts on, take ownership of this responsibility. Apply when you are prepared to be accountable for system reliability, third-party integrations, and the automation infrastructure that empowers the broader team to operate at higher speed.
