About the role

When our sales team closes a deal with a marketplace or platform business that needs to move their payments infrastructure to Whop, someone has to take that deal off the sales rep's plate and drive the technical integration to completion. That's you. You're the first engineer these businesses work with after signing. You assess their existing tech stack, jump on calls with their engineering team, build a concrete migration plan, and drive it to completion. You're not handing off a doc — you're in their codebase, on the calls, and accountable for the business going live on Whop.

You know Whop inside and out. You know how connected accounts work, how to set up direct charges vs. transfers, how to embed the payout portal, how webhooks fire on payment.succeeded, and how to enroll sub-merchants via the API. Sometimes closing a deal means building what doesn't exist yet. If a prospect needs an MCP server, a public SDK integration, an AI agent skill, or a reference app to see how Whop fits into their stack — you build it. You contribute directly to Whop's public developer surface (docs, SDKs, example apps, MCP tools) whenever that's what it takes to land or accelerate a deal.

You also close the loop back to our core engineering team. When you see the same integration friction three times, you drive the product change that eliminates it. You're always on, always responsive, and pushing timelines. This role reports to the Head of Partnerships.

Scope

• Own technical integrations end-to-end — from deal close through the business going live on Whop Payments Network
• Assess existing tech stacks — understand the business's current payment infrastructure, APIs, databases, and workflows before writing a line of integration code
• Build concrete, time-bound migration plans tailored to each business's architecture and constraints
• Jump on with client engineering teams — join their calls, review their implementation, pair on connected account onboarding, unblock them when they're stuck on KYC flows or webhook handling
• Be the fastest response in the client's inbox — unblock engineers quickly so integrations don't stall waiting on you
• Build and contribute to Whop's public developer tools — MCP servers, SDK integrations, AI agent skills, example apps — whenever it helps close or accelerate a deal
• Write and improve developer docs, integration guides, and onboarding content based on what you learn in the field
• Track progress against integration plans, flag risks early, and keep deals from stalling post-close
• Build migration scripts, reference implementations, and reusable tooling that make the next integration faster
• Identify recurring friction in the integration process and work directly with Whop's core engineering team to fix it at the platform level
• Work closely with product to ensure we're constantly adding new value to our offer

What we’re looking for

• Successfully built your own business or side project
• You love Whop — you've used the platform, maybe built on it, and you're excited to learn every corner of it
• Extremely curious & personable
• World class work ethic
• AI-native — you live in Cursor, Claude Code, Codex and are always pushing for better workflows
• Organized and diligent — you maintain a clear pipeline and nothing falls through the cracks
• Hands-on experience integrating with payment systems
• Strong full-stack engineering ability
• Strong communication skills and instant response times
• High attention to detail; cares deeply about correctness
• Low-ego, non-performative, and process-driven
• A scrappy, experiment-driven mindset: no task too small, no idea too big
• Want to take over the world and are not satisfied with anything other than being the best
• Previous experience in technical consulting, solutions engineering, or professional services is nice but not a requirement.
• Familiarity with marketplace payment flows (splits, payouts, sub-merchant onboarding) is a plus.

Your first 90 days

• Within 30 days, you will deeply study Whop's payment APIs (connected accounts, checkout configurations, webhooks, payout portal), shadow 3+ integration calls, and have taken ownership of your first integration.
• Within 60 days, you will have multiple integrations in flight and be the primary technical point of contact for each business.
• Within 90 days, you will have multiple businesses live on Whop and a repeatable playbook that makes every future integration faster.
