Senior Product Manager, Advertiser Experience

Instacart is transforming the grocery industry by delivering groceries and household goods while creating flexible earning opportunities for personal shoppers. The Senior Product Manager will own advertiser value measurement, reporting and insights experiences, and core platform capabilities supporting campaign creation, management, and reporting. The role also involves partnering with advertisers, agencies, and cross-functional teams to drive product strategy and delivery.

Responsibilities:

• Own the problem space of advertiser value measurement — defining how advertisers understand, trust, and act on the results they're seeing from Instacart Ads campaigns, and building the reporting and insights experiences that make that possible
• Own and evolve core platform capabilities that support all stages of the advertiser journey, including API infrastructure, product library, user management, change history, billing, and notifications — ensuring these foundations are reliable, scalable, and built to support a sophisticated advertiser base
• Serve as a primary product point of contact in external conversations with advertisers and agency partners — sharing roadmap direction, gathering strategic feedback, and helping to nurture relationships that inform product decisions and drive trust in the platform
• Work cross-functionally across a 100+-person Ads R&D team — collaborating with engineers, data scientists, designers, and researchers — as well as with sales, strategy, and commercial enablement teams to drive alignment and deliver impact across a complex, fast-moving organization
• Grow into a senior PM lead for the Advertiser Experience team over time, including providing strategic guidance and serving as a thought partner to a more junior PM on the team, as you demonstrate command of your scope and expand your ownership footprint

Requirements:

• 5+ years of product management experience, with a track record of independently owning complex, cross-functional product areas
• Experience building or owning B2B platform products, including enterprise UX flows and underlying platform infrastructure
• Strong technical acumen — comfortable engaging deeply with engineering teams on system design, APIs, and platform architecture
• Experience managing external partner or customer relationships as part of a product role, not just internal stakeholders
• Strong written and verbal communication skills, with the ability to synthesize complex technical and business context for both engineering teams and executive audiences
• Experience in ad tech, retail media, or marketplace advertising, particularly on the demand or advertiser side — for example, owning advertiser-facing campaign management or reporting flows
• Familiarity with programmatic advertising concepts, including auction mechanics, ad serving, attribution, billing and revenue share, and reporting infrastructure
• Prior experience at a company where the platform you owned enabled third-party businesses to operate — such as a white-label ad platform, a marketplace API, or an embedded commerce product
• Experience driving strategic expansion into new business verticals or partner segments
• Demonstrated ability to ship in ambiguous, high-stakes environments where product scope, technical constraints, and business requirements are evolving simultaneously
