Attentive is an AI marketing platform for 1:1 personalization that unifies SMS, RCS, email, and push notifications. The Identity team owns Attentive's first-party data collection platform—the systems that capture ecommerce and user behavior events from customer storefronts, forming the core data that powers Attentive's marketing tools.
As a Senior Software Engineer on this small, autonomous team (3-4 engineers), you'll have broad ownership across the full stack. You'll work on a JavaScript tag embedded on thousands of sites serving millions of consumers daily, Cloudflare Workers handling server-side tracking and edge compute, and backend ingestion services. The team is leaning heavily into AI to improve data collection quality and volume, with the goal of evergreen first-party data collection that can automatically measure its own performance and ship improvements.
Key responsibilities include: owning data collection across the full stack (JS tag, Cloudflare Workers, Java backend services); expanding edge compute capabilities with Cloudflare Workers for tag serving, A/B configuration, and agentic systems; building AI systems to identify and automatically fix data collection gaps; strengthening the backend event ingestion pipeline for reliability and observability; and helping lead technical direction through design reviews and mentorship.
You'll need 6+ years of professional software engineering experience working across multiple system layers. Backend expertise in Java, Kotlin, or similar typed languages is required, along with comfortable JavaScript/TypeScript skills and experience with edge compute or serverless runtimes. You should have a track record of leading projects from scoping through shipping, strong debugging instincts across service boundaries, and active use of AI-assisted development tools (Claude Code, Cursor, Codex) in production workflows. Willingness to work across unfamiliar parts of the stack is essential.
