You will partner closely with Sales, Project & Program Management, Business Analysts, Engineering, and other departments to deliver high-quality, scalable solutions for high-growth and high-volume eCommerce clients. You will engage from pre-sales through Build, acting as a strategic technical leader who drives clarity, alignment, and informed decision-making across client, partner, and internal stakeholders. This role blends hands‑on technical expertise with architectural oversight, enabling you to shape platform decisions, integrations, and custom development approaches across the agency's enterprise engagements. As a key contributor in a fast‑paced agency environment, you will help shape best practices, evaluate emerging technologies, and ensure our Shopify solutions are future-ready, maintainable, and aligned with both short-term client goals and long-term business strategy.

Set up proof‑of‑concept prototypes during Discovery as appropriate, de‑risking uncertain technical approaches before committing to a full build. Produce and maintain comprehensive technical documentation including architecture diagrams, data flow processes, API schemas, and system integration maps. Partner with Project/Program Management to support Discovery planning, tracking, and client status updates. Identify areas of complexity, technical risk, and scope‑impacting factors during Discovery, and work toward a scope and solution that optimizes these parameters.

Design end‑to‑end system architectures for complex Shopify Plus implementations, ensuring scalability, security, and performance across both B2C and B2B contexts. Determine integration approaches across the client's broader enterprise stack — including ERPs, CRMs, OMS/WMS, PIMs, payment gateways, shipping providers, tax engines, and marketing platforms — balancing out‑of‑the‑box connectors against custom builds. Define the technical framework for custom Shopify apps, themes, and middleware solutions tailored to client needs, including functional requirements, integration points, and data flows. Plan data and platform migrations — defining strategy, data mapping, sequencing, and risk mitigation — for clients moving off legacy enterprise platforms. Evaluate composable and native approaches to Shopify, and recommend the right architecture for each engagement based on requirements, constraints, and long‑term goals. Evaluate when to leverage Teifi's proprietary product suite (such as WorkMate) versus custom builds or third‑party solutions, balancing speed‑to‑value, cost, and long‑term maintainability.
