Solutions Engineer, Sales & Partnerships

About the role

At Tapcart, we believe every brand needs a direct relationship with their customers - one they actually own. We are the mobile commerce engine that powers shopping for Shopify's fastest-growing brands. $15B+ in revenue processed. 200M+ shoppers worldwide. Brands like Princess Polly, Béis, Forever 21, and Young LA rely on us to power a large portion of their revenue. We're a lean team with minimal management and big autonomy. Everyone here builds and code is core to what we do - engineers, product, leadership. We use our own platform, we talk to merchants daily, and we ship constantly. Backed by Shopify, Silver Lake and other top VCs. Profitable and growing. If you want a place where you own real outcomes, not just tickets, you'll fit in. Why join Tapcart when you have a sea of other options? You want to be the technical voice in the room - on a sales call one hour, whiteboarding an integration spec with an agency dev the next. You're a builder - you'd rather sharpen an in-progress onboarding process into something scalable than wait for a finished playbook. You'll have a manager who clears the path, not one who watches every step. Don't Proceed With Applying If You don't use AI tools daily to work faster and smarter. You can't hold your own with a CMO one hour and a developer the next - both audiences need the real answer. You need a fully-built process handed to you. This one's yours to stand up.

Responsibilities

• Partner with AEs as the technical lead on prospect and expansion deals - scoping what's native vs. custom, and giving buyers the confidence to sign
• Run technical discovery on a brand's stack (Shopify plan, headless, subscription, loyalty, CDP, ESP) and turn it into a clear path to launch
• Own the external developer and agency partner onboarding process end to end - docs, environment setup, sandbox access, rules of engagement
• Author specs for integrations and custom builds, review partner deliverables against them, and unblock developers as they build
• Feed recurring partner and customer needs back to Product as structured input for the roadmap
• You'll be a true owner from first technical call to shipped integration, working side-by-side with Sales, Product, and partner developers, while staying close to merchants to deliver value early and iterate quickly.

Qualifications

• 3+ years in solutions engineering, sales engineering, or a partner/developer-facing technical role - ecommerce
