Senior Sales Engineer for Local Payment Integrations — Hybrid, Chicago, United States

Overview

Guide enterprise merchants, payment providers and marketplaces through the technical decisions behind a payment integration. This senior sales engineering role covers local payment methods, unified APIs and merchant-of-record solutions, connecting commercial requirements with a design that customer engineering teams can implement.

Requirements

• The position calls for at least five years in customer-facing solutions engineering, technical sales or integration consulting within payments, fintech or ecommerce.
• Strong experience with REST APIs, JSON, webhooks and API testing tools is required, alongside knowledge of processing, authorization, acquiring and local methods.
• Scripting skills are useful, and Spanish or Portuguese is an advantage rather than a requirement.

Responsibilities

• Lead technical discovery, workshops and proposal responses.
• Assess checkout flows and business rules, explain integration choices, and prepare accurate answers to architecture and security questions.
• Where customers are modernizing an existing setup, help them understand the implications of moving to new APIs or adding regional payment rails.
• Continue into implementation scoping and launch preparation by reviewing requirements, test payloads and webhook behavior.
• Support initial transaction flows and business-hours escalations, then provide a clear handover to the teams responsible for ongoing service.
• Customer feedback should inform product and engineering priorities throughout the engagement.

Conditions

• The role follows a hybrid arrangement in Chicago with three office days per week.
