We are Subway Headquarters! A dedicated team of professionals supporting thousands of franchisees around the globe.

Sr. SDET (Senior Software Development Engineer in Test, Merchandising Automation)

Ready to build what’s next with one of the world’s most iconic brands?

Why Join Subway?

At Subway, we are not standing still. We are building.

This is a business focused on what matters most: growing franchisee profitability, strengthening our brand and creating long-term value. The people who thrive here are the ones who want to make a real impact.

You will not just do the work. You will shape it.

We move fast. We think like owners. We make decisions that matter. We hold ourselves to a high standard because what we do directly impacts thousands of franchisees around the world.

If you bring energy, accountability and a bias for action, you will fit right in.

We take the work seriously, but we also know the best results come from teams that support each other, celebrate wins and show up ready to build something better every day.

This is your chance to be part of what’s next.

About the Role:

Subway’s Merchandising Automation team is building the integration and data pipelines that replace manual Digital Merchandising workflows across owned channels and third‑party delivery partners — and the Sr. SDET is the engineering voice of quality in that effort. You will design, build, and operate the automated test frameworks that validate everything the team ships: the Node.js/Type Script APIs and AWS event‑driven pipelines that power menu publishing and promotional scheduling, and the Adobe Workfront Fusion scenarios built by the Marketing Automation Engineer that connect Subway’s creative and campaign toolchain to downstream systems.

This is an engineering‑first role. You will write production‑quality test code, architect scalable test frameworks, and embed automated quality gates directly into CI/CD pipelines. You will partner with integration engineers from the earliest stages of design — shaping APIs and Fusion scenarios for testability, defining acceptance criteria, and ensuring quality is built in rather than bolted on. A unique and differentiating aspect of this role is fluency across two distinct integration paradigms: AWS‑native event‑driven services on one side, and Adobe Workfront Fusion’s scenario‑based iPaaS model on the other.

AI‑assisted development is a core part of how this team works. You’ll be expected to use tools like Git Hub Copilot and Claude daily — to accelerate test authoring, generate synthetic merchandising test data, analyze failure patterns, and document coverage — and to champion their adoption across the engineering team.

Responsibilities include but not limited to :

• Lead the design and development of automated test frameworks and suites covering functional, integration, contract, performance, and end‑to‑end scenarios for Subway’s Digital Merchandising platform — spanning the Node.js/Type Script APIs and event‑driven pipelines that drive menu publishing, promotional scheduling, and item availability across Mobile App, Web, Kiosk, and third‑party delivery partners. Write test code to the same quality standards as production code.
• Leverage AI‑assisted development tools (Git Hub Copilot, Claude, and similar) as a core part of daily engineering work — from generating and refining test cases and synthetic merchandising data to analyzing failure patterns, mapping coverage gaps, and producing documentation. Champion AI tooling adoption across the team.
• Own validation coverage for the Workfront Fusion integration layer built by the Marketing Automation Engineer — designing test strategies that verify Fusion scenario outputs, data mapping fidelity, webhook reliability, and cross‑system data integrity between Adobe Workfront, downstream marketing tools, and Subway’s internal platforms. Catch scenario failures and data mismatches before they reach production.
• Partner with the Merchandising Automation integration engineers and the Senior Quality Engineer throughout the development…
