Solution / Application Architect – OMS Migration
We’re looking for a hands-on Solution/Application Architect to lead the design and modernization of a middleware component within an Order Management System (OMS) for a large retail client based in Markham, Ontario.
The organization is transitioning away from a third-party SaaS OMS platform and bringing the middleware solution back in-house. You’ll be responsible for shaping the architecture, integration strategy, and event-driven design as the company moves from a legacy monolithic setup to a modern, scalable cloud-native solution.
What You’ll Do:
- Lead the overall architecture and integration design for the new OMS middleware.
- Design and document solution diagrams, APIs, message flows, and integration touchpoints.
- Collaborate closely with teams across AS400, Zendesk, payment gateways, e-commerce, and data warehouse systems.
- Implement and guide event-driven, microservices-based patterns using Azure technologies (Event Hub, Kafka, or MQ).
- Work with a small middleware development team to deliver scalable, high-performing solutions.
- Identify and manage risks around third-party or “black box” vendor systems.
- Participate in knowledge transfer, discovery sessions, and solution validation with the OMS Manager.
Technical Environment:
- Cloud: Azure (AKS, containers, cloud-native services)
- Architecture: Event-driven, microservices, API-first (REST/gRPC/GraphQL)
- Messaging: Kafka, MQ, or Event Hub
- Data: SQL Server and Cosmos Database (NoSQL)
- Integrations: AS400 (legacy OMS), Zendesk, payment gateways, e-commerce platforms, data warehouse
- Performance & Security: Redis/Memcached caching, API gateways, OAuth2/JWT authentication
Must-Haves:
- Proven experience as an Application or Integration Architect in retail, commerce, or OMS environments
- 5+ years in microservices-based architecture, including 1–2 years in event-driven systems (Kafka/Event Hub)
- Strong experience with Azure, AKS, and containerized deployments
- Hands-on experience designing and integrating APIs with proper versioning and security
- Solid development foundation in Java or .NET
- Familiarity with payment gateway integrations (refunds, charges, reconciliation)
- Comfortable working with legacy systems (AS400) and limited-visibility vendor products
- Excellent communication skills — able to explain technical designs to both business and technical stakeholders
- Comfortable attending on-site whiteboard sessions and presenting architectural solutions
