Senior Software Engineer II - Enterprise Foundations

Responsibilities

• Own a multi-quarter integration workstream end to end — for example, unified customer identity across FoodStorm and Storefront Pro, international storefront and search expansion for enterprise retailers, or consolidation of bespoke retailer-vertical services onto shared Instacart platform rails — from problem framing…
• Drive the technical direction for your area: write the ERDs, propose the options, make and defend the trade-off calls, and bring partner teams along through design reviews and written artifacts that read clearly for first-time readers.
• Lead vendor and cross-team integrations where Instacart will eventually own the system — push for the right observability, fallback behavior, and cost/latency guardrails up front, and challenge partner designs early rather than inheriting them at handoff.
• Build reusable patterns, frameworks, and templates that other engineers across Enterprise Foundations and adjacent teams adopt with minimal hand-holding; treat "system at a glance" docs and migration runbooks as first-class deliverables.
