Solutions Engineer

We are seeking a talented and motivated Solutions Engineer who is best in class with a high IQ plus a high EQ. This role presents an exciting opportunity to thrive in a dynamic, fast-paced environment within a rapidly growing team, with abundant prospects for career advancement.

As a Solutions Engineer, you are the technical owner of the merchant relationship from first sales conversation through live integration and beyond. You will focus on our enterprise and strategic merchants: the national retailers and high-volume brands running custom, hand-built integrations across web, mobile app, and in-store. These are our most complex merchants and our largest revenue drivers, and they do not come with an off-the-shelf plugin.

You will partner with Sales, Product, and Engineering to scope what a merchant needs, design the integration that gets them there, and stay with them once they are live. You own the technical side of pre-sales: demos, architecture discussions, RFP responses, and solution proposals. When a merchant needs something custom, you define the requirement, shape the solution with our engineering team, and drive it to launch.

This is a customer-facing engineering role. You will spend as much time on calls with merchant developers as you will in documentation and test environments, and you need to be credible in both rooms.

This role combines technical expertise and sales acumen to support sales teams. They work closely with the sales team and clients, understanding customer needs and translating them into effective, tailored solutions. Acting as a bridge between technical and business functions, a Solutions Engineer not only helps demonstrate and implement the product’s capabilities but also communicates complex technical details in a way that resonates with clients. Their role requires both the ability to engage with customers directly and the technical know-how to ensure the product meets client requirements effectively.

What You'll Do:

Own technical discovery for prospective merchants: understand their stack, their checkout flow, and their constraints, then map them to the right Sezzle integration path

Lead product demos and technical presentations for merchant engineering and business stakeholders

Design integration solutions across our API, SDKs, and platform plugins (Shopify, BigCommerce, Magento, WooCommerce, Wix, and custom builds)

Write technical proposals and complete RFP and security questionnaire responses

Support merchant mobile app integrations: SDK implementation, in-app checkout, and native versus webview handoff

Validate integrations in sandbox and in production before launch, including checkout flow, widget and messaging placement, redirect and handoff behavior, and settlement

Troubleshoot live integration issues alongside Support and Engineering, and own the technical narrative back to the merchant

Translate recurring merchant needs into product feedback, and push for the fixes that unblock revenue

Build and maintain integration documentation, runbooks, and internal enablement so the team scales without you in every call

Act as the trusted technical advisor for your merchants after launch, spotting optimization opportunities they haven't asked for yet
