## Job Description
Enterprise / Strategic Merchants (SL-Enterprise Sales)

About the role
This is a customer-facing technical owner for enterprise and strategic merchants: national retailers and high-volume brands with custom, hand-built integrations (not off-the-shelf plugins).
You own the merchant relationship from first sales conversation through live integration and after launch. You work with Sales, Product, and Engineering on discovery, solution design, RFPs, custom work, launch, and ongoing technical advising.
Time is split between merchant-developer calls and documentation / sandbox / production validation.

What you'll do
Own technical discovery: stack, checkout flow, constraints → Sezzle integration path
Lead demos and technical presentations for engineering and business stakeholders
Design integrations across API, SDKs, and platform plugins (Shopify, BigCommerce, Magento, WooCommerce, Wix, and custom builds)
Write technical proposals; complete RFPs and security questionnaires
Support mobile app integrations (iOS/Android SDKs, in-app checkout, native vs webview)
Validate sandbox and production: checkout, widgets/messaging, redirects/handoff, settlement
Troubleshoot live issues with Support and Engineering; own the technical narrative to the merchant
Turn recurring merchant needs into product feedback
Build docs, runbooks, and internal enablement
Stay on as post-launch technical advisor and look for optimization opportunities

What they look for
4+ years customer-facing technical work: solutions engineering, sales engineering, implementation, solutions architecture, or TAM
Mobile SDK experience (iOS and Android): guide merchant developers and debug
Enterprise / multi-stakeholder custom commerce-stack integrations
REST APIs, webhooks, reading API docs critically
HTML, CSS, JavaScript
Familiarity with at least one major ecommerce platform (Shopify, BigCommerce, Magento, WooCommerce, Wix) and how payments plug in
Ecommerce workflow literacy: cart, checkout, auth/capture, refunds, shipping, catalog
Explain tech to non-technical people and business context to engineers
Strong writing (docs and proposals)
Handle several integrations at once
Read code in at least one language well enough to debug a merchant implementation
Use AI tools for research, docs, problem-solving, and workflow automation

Preferred
Payments / PSP / BNPL background
Payment gateway architecture and alternative payment methods at checkout
In-store or omnichannel payment integrations
CS/CE degree or equivalent experience
