Description

Amazon is seeking an Application Engineer with strong system design skills to join our Checkout Engineering team in Austin, TX. This role will focus on two key areas: (1) payment systems across all WFM stores globally, and (2) international point-of-sale (POS) software integration for WFM locations in Canada and the UK.

The ideal candidate will own the "how" of delivering robust, scalable solutions, while contributing significantly to the "what" of our payment and POS systems. You will be the technical driving force behind implementation strategies and best practices, playing a key role in shaping the design and development of these critical systems.

Key job responsibilities

Leading technical design discussions that impact payment processing and international POS integration

Implementing critical components of payment and POS systems

Creating design specifications for complex integration points between payment providers and POS systems

Establishing patterns for automated testing strategies and monitoring solutions

Developing automated alerting systems based on transaction log analysis, with the ability to identify both present and absent critical data elements in payment flows

Collaborating with cross-functional teams to ensure designs meet business requirements

Reviewing and providing guidance on technical designs and implementations

A day in the life

As an Application Engineer, your day centers on driving operational excellence within our SAFe framework. You'll tackle a prioritized backlog of improvements, focusing on system performance, and reliability. Collaborating with vendors and cross-functional teams, you'll progress high-priority items while providing daily support for critical POS functions. You'll participate in SAFe ceremonies, and engage in architecture discussions. Your expertise will be crucial in mentoring junior members and translating stakeholder requirements into innovative technical solutions that propel our global retail operations forward.
