Overview

The Marketing Enablement & Technology (MET) team sits within Instacart's Marketing organization, building the systems that power how Instacart markets, measures, and grows. The CRM Enablement pod builds execution-layer tooling on top of Instacart's CRM and messaging platforms—owning the end-to-end email execution workflow from email development, coding and compiling emails using our React-based component library, to QA'ing all CRM touchpoints across email, push, SMS, and in-app. We're seeking a Senior Software Engineer to develop emails and architect componentized template systems, compilation pipelines, and automation tools that enable marketers to launch campaigns efficiently. You'll lead projects end-to-end, drive technical direction, and partner closely with Lifecycle Marketing, CRM Ops, Creative, and Product to translate business goals into scalable, reliable solutions.

About the Job

• Architect scalable full-stack solutions spanning frontend (React, Next.js) and backend (Ruby, REST APIs, GraphQL) that power marketing operations, integrate with ESPs (Braze, Salesforce Marketing Cloud), and handle high-volume campaign delivery.
• Design and implement reusable abstractions, frameworks, and patterns that simplify complexity for both engineers and marketers, improving developer productivity and enabling self-service campaign creation.
• Build robust APIs and services using Ruby, SQL, and modern databases (PostgreSQL, MongoDB, Snowflake) that support personalization, targeting, experimentation, and real-time campaign orchestration.
• Develop responsive, accessible HTML/CSS rendering systems and establish standards for cross-client compatibility, performance optimization, and comprehensive observability (logging, metrics, tracing).
• Partner directly with Marketing and Product stakeholders to influence platform roadmap, translate business requirements into technical solutions, and make well-reasoned trade-offs between complexity, business value, and delivery timelines.
• Mentor junior engineers through code reviews, technical guidance, and onboarding support while contributing to team productivity through process improvements, automation, and platform enhancements.
