About The Position

Instacart is seeking a Senior Engineering Manager to lead the Enterprise Foundations engineering team, responsible for the architectural and integration work that enables Instacart's Retailer Platform to scale globally. This team's work is crucial for omnichannel integrations, enterprise extensibility (sandbox environments, configuration systems, retailer-facing tooling), and data isolation for ML and Data Engineering teams. The role involves setting the technical direction for multi-tenancy, data isolation, configuration-driven release management, and per-retailer extensibility, driving the consolidation of bespoke services into shared platform rails. The manager will partner with various internal teams to broker architectural and prioritization trade-offs for enterprise retailers across multiple commerce surfaces.

Requirements

8+ years of software engineering experience, including 3+ years managing engineering teams delivering platform or infrastructure products in a B2B or enterprise context.
Experience leading teams of 10+ engineers, including hiring, performance management, and career development of senior individual contributors.
Demonstrated success operating in ambiguous, high-growth environments where partner roadmaps, product coverage, and integration commitments are still maturing.
Proven cross-functional leadership influencing outcomes across multiple engineering and product organizations, including comfort using structured escalation to unblock multi-team initiatives.
Experience leading multi-team architectural transitions such as consolidation, replatforming, multi-tenancy, or data isolation inside an established business with real customers and revenue.
Technical proficiency in distributed systems, API/SDK design, and cloud infrastructure (e.g., AWS or GCP).
Bachelor's degree in Computer Science or a related technical field, or equivalent practical experience.

Nice To Haves

Direct domain experience in commerce platforms, omnichannel retail, OMS, POS, catering systems, or connected-store / in-store technology.
Track record of building multi-tenant platforms serving multiple internal or external customers, with per-tenant configuration, isolation, and extensibility requirements.
Experience partnering with ML and Data Engineering teams on data platform compliance, model training infrastructure, or data isolation initiatives.
Background scaling enterprise integrations and managing partner-facing technical relationships across product, engineering, and customer-facing functions.
Experience leading other engineering managers and growing two-layer organizations.

Responsibilities

Lead, coach, and grow a senior-skewed team of ~12 engineers across multiple workstreams.
Set clear architectural and execution direction, develop talent, and foster a culture of ownership, accountability, and continuous improvement.
Set and maintain the unifying technical thesis for the team — multi-tenancy, data isolation, configuration-driven release management, and per-retailer extensibility.
Drive consolidation of bespoke retailer-vertical services onto unified Instacart platform rails.
Partner with ML and Data Engineering on long-term enterprise data platform compliance for ML systems.
Deliver self-service tooling — including sandbox environments, configuration interfaces, and retailer-facing extensibility.
Represent technical and product trade-offs across multiple engineering and product organizations.
Broker resourcing decisions, drive clarity in ambiguous scope, and ensure engineering investment stays aligned with committed work.
