• We're hiring an engineer who can both reason about CAC/LTV and write the code that moves it. • This is not a marketing job — it's an engineering job pointed at revenue: instrumented, production-grade systems for demand capture, lead routing, and experimentation, replacing manual workflows inside a running marketing operation. • If you've worn the growth hat and the engineering hat — instrumenting funnels, wiring data pipelines, automating the manual stuff, prototyping with whatever tool gets to a result fastest — this is that job, full-time. • AEO and inbound: surfacing in search and AI-generated answers; capture, routing, and speed-to-lead instrumented so inbound converts.
