Overview The Marketing Enablement & Technology (MET) team sits within Instacart's Marketing organization, building the systems, data pipelines, and platforms that power how Instacart markets, measures, and grows. Operating at the intersection of Marketing, Product, and Engineering, we own the platforms behind organic search visibility, campaign feeds, audience targeting, event pipelines, and QA automation. We're seeking a Software Engineer II who will build across two of our highest-leverage growth surfaces: Technical Search Visibility (SEO) and CRM Enablement. On the SEO side, you'll ship full-stack features that improve Instacart's search engine and AI answer engine visibility across millions of web pages and drive organic traffic. On the CRM side, you'll build and evolve the componentized email system and execution tooling that gets lifecycle campaigns from brief to send across email, push, SMS, and in-app. You'll own features from build through rollout, contribute to technical decisions, and partner closely with Marketing and Product to turn growth requirements into scalable, testable customer experiences. This is a hands-on role that spans both pods. You'll move between organic-traffic engineering and CRM execution tooling, so we're looking for someone who's comfortable being a full-stack generalist and going deep in whichever surface the work calls for.

Build automation and internal tooling that cuts QA and setup time across both surfaces, from SEO experimentation to CRM deep-link and token coverage.
