Customer Success Engineer, Enterprise Engineering

Role

The Enterprising Engineering team, nested within our Seller Engineering org, supports the needs of our largest and most complex sellers. As sellers grow their businesses on Whatnot, their needs evolve—and this team builds the systems and tooling to support them at scale, including integrations with e-commerce platforms, WMS, ERPs, and accounting software.

This Customer Success Engineer will operate at the intersection of engineering, product, and customer partnership—working directly with enterprise sellers and their technical teams to design, implement, and support custom integrations on top of Whatnot’s APIs and infrastructure.

The role is highly technical and highly collaborative, combining hands-on integration work with customer-facing problem solving and product thinking. You’ll help enterprise partners navigate complex workflows across inventory, logistics, order management, and operational systems while partnering closely with internal engineering, product, and account teams.

Responsibilities

• Partnering directly with enterprise sellers and their engineering teams to architect and implement bespoke integrations leveraging Whatnot’s APIs and platform capabilities.
• Acting as the technical bridge between customers and internal teams—translating seller needs into scalable solutions while collaborating closely with engineering, product, and account management stakeholders.
• Building durable tooling, workflows, and support infrastructure that help scale enterprise onboarding, integration support, and long-term customer success, including ~20–30% hands-on coding focused on developing scalable integration solutions and internal operational tooling.
• Solving complex post-sale technical challenges while helping define how Whatnot supports enterprise commerce moving forward.

Requirements

• Bachelor’s Degree in Computer Science or related field or equivalent work experience.
• Experience building bespoke solutions on top of an existing internal framework.

• Strong written and oral communication skills.
• Strong presentation skills and ability to articulate customer needs to engineering product teams.
• Able to take ownership of an ambiguous area and define and then drive impact.
• Able to flexibly work across multiple workstreams, thriving in a fast-paced environment.
• Able to understand complex customer success workflows and envision and build tooling to better support our bespoke system.
• Experience in Shopify, Channel Advisor, Magento, and other ecommerce SaaS products a plus.
