Growth Marketing Systems & Experiments Lead

About Base Base is America’s next-generation power company. We’re rebuilding the foundation of modern civilization–electricity–by deploying a vast network of distributed batteries that is transforming today’s fragile, centralized grid into a resilient and abundant system. We are engineers, operators, and creatives solving some of the most complex, interdisciplinary challenges of our time. About the Role Base is looking for an excellent operator to help scale the systems behind our customer acquisition engine. This role is responsible for increasing the speed, intelligence, and effectiveness of how marketing operates. You will drive experimentation across lifecycle, referrals, customer engagement, and operational workflows, while building the systems, automation, and infrastructure that make that experimentation scalable. You will identify bottlenecks, design better systems, implement automation, improve measurement, launch experiments, and operationalize new workflows across the business. In many cases, you will not just help define strategy, you will execute it directly. A major part of the role is lifecycle and customer engagement strategy. You will own how we engage customers across onboarding, activation, referrals, retention, and winback, continuously testing and improving performance through segmentation, messaging, incentives, timing, routing, and operational design. The ideal candidate is highly resourceful, systems-oriented, technically curious, and obsessed with finding leverage. You should be equally comfortable thinking strategically, digging through data, building workflows, launching experiments, and executing quickly in ambiguous environments. What You'll Do Drive experimentation across lifecycle, referrals, onboarding, engagement, retention, and growth operations. Build systems, workflows, and automation that improve the speed and effectiveness of the Marketing team and broader Growth organization.

Partner closely with Growth, Product, Engineering, Data, Sales, and Support teams to improve systems and customer experiences across the funnel. Improve instrumentation, event tracking, operational visibility, and data quality across growth systems. What You'll Bring You are highly execution-oriented and naturally default toward building, shipping, and improving systems.

Ability to operate independently and execute quickly in ambiguous, fast-moving environments. Technical fluency and curiosity. You are comfortable learning tools, implementing workflows, and working closely with technical teams. Strong judgment and a bias toward action. High ownership and accountability.
