The opportunity
Enterprise Foundations is the engineering team responsible for the architectural and integration work that allows Instacart's Retailer Platform to scale across the world's largest grocers. Our work spans omnichannel integrations — bringing products like FoodStorm catering and…
What you'll do
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 through design, implementation, rollout, and deprecation of legacy paths.
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.
Operate hands-on as a senior individual contributor on the highest-leverage: technical work in your area; raise the bar on design quality, code quality, observability, and operational rigor.
Mentor more junior engineers in your area, delegate well-defined: implementation pieces while retaining overall technical ownership, and act as a credible technical peer to senior and staff engineers in adjacent organizations.
What they're looking for
- Direct domain experience in commerce platforms, omnichannel retail, OMS, POS,: catering systems, or connected-store / in-store technology.
- Experience with customer identity, account linking, or SSO integrations: across multiple consumer-facing surfaces.
- Experience building or scaling search, retrieval, or ranking systems,: including integrations with third-party search providers.
- Background working on international expansion: localization, data residency, multi-region infrastructure, or in-country compliance requirements.
- Experience leading vendor or partner-owned integrations where the system is: ultimately operated and owned by the integrating team.
- Experience designing per-tenant configuration, isolation, and extensibility: for multi-tenant enterprise platforms.
