Our remote, co‑located teams are anchored in hubs across the US, UK, Ireland, Poland, Germany, and Australia. We move fast, stay close to users, and focus on high‑impact work.

Role

The Seller Growth Engineering team helps new sellers succeed—from application to first livestream to building thriving businesses. Within Seller Growth, the Seller Lifecycle Growth/Enterprise team builds systems that provide every seller with knowledge, guidance, and confidence to activate, grow, and scale.

As Engineering Manager for Seller Lifecycle Growth/Enterprise, you will lead a team that builds Whatnot’s seller onboarding and education platform, owning systems that identify seller potential early and power differentiated onboarding and education experiences based on predicted long‑term value. You partner closely with Product, Design, Data Science, and Marketing to craft personalized educational experiences throughout the seller journey and define the technical strategy for coaching sellers to success.

This unique opportunity involves building both customer‑facing experiences and the underlying content systems, tooling, and platform capabilities that enable consistent, voice‑aligned seller education across product and internal teams.

Responsibilities

• Hire, develop, and grow a high‑performing team of engineers across backend, web, and mobile.
• Partner closely with Product and Design to define the long‑term vision for seller education and the technical investments needed to support it.
• Drive platform investments that enable contextual delivery of educational content throughout the seller experience, rather than standalone documentation.
• Build and own experimentation, measurement frameworks, and goals around seller education impacting seller activation, engagement, retention, and business growth.
• Plan and execute ambitious cross‑functional projects while coordinating dependencies across Engineering, Marketing, and international product teams.
• Foster a strong engineering culture centered around ownership, technical excellence, and rapid iteration.

We offer flexibility to work from home or from one of our global office hubs, and we value in‑person time for planning, problem‑solving, and connection. Team members in this role must live within commuting distance of our New York or San Francisco hub.

• Hands‑on technical leadership experience building and operating large‑scale distributed systems and complex web and mobile applications.
• Strong product and design instincts, with an understanding of how user experience and technical architecture work together to deliver great products.
• Comfortable making pragmatic decisions around technical debt and balancing short‑term execution with long‑term maintainability.
• Experience defining and leveraging product metrics, with a strong understanding of both the value and limitations of data.
• Ability to effectively manage stakeholders, navigate competing priorities, and operate successfully in ambiguous environments.
• Significant hands‑on engineering experience in the domain you’ll be leading, enabling credibility with technical teams.
• Bachelor’s degree in Computer Science or equivalent practical experience.
