WMS Application Developer in Mississauga

NOTE: THIS IS A 4-MONTH CONTRACT WITH POSIBILITY OF EXTENSION

Duties and Responsibilities

• Design, code, test and deploy custom WMS functionality in Advantage Architect, including process objects, business logic and database actions.
• Build and modify RF (handheld) and web screens using Page Editor to support client-specific warehouse workflows.
• Configure and extend core warehouse processes, including receiving, putaway, replenishment, order release, picking, packing, shipping, cycle counting and returns, for new and existing 3PL clients.
• Develop client onboarding solutions: owner, item and location setup, client-specific rules, and labels and documents such as GS1/UCC-128 labels, bills of lading and packing lists.
• Write clear, maintainable code to Remco development standards and take part in peer code reviews.
• Keep all custom code in source control and promote changes through Development, Test and Production using a documented change and release process.

No direct changes in Production without approval.

• Build customizations so they survive vendor upgrades: extend rather than modify core vendor objects, and document every customization.
• Database Development (MS SQL Server)
• Write and optimize T-SQL stored procedures, functions, triggers and views supporting WMS logic, integrations and reporting.
• Design tables and data structures for custom extensions, and tune queries and indexes to keep WMS transactions fast at peak volume.
• Build and maintain SSIS packages and SQL Agent jobs for data loads, extracts and scheduled processes.
• Develop SSRS and Crystal reports and operational dashboards, including inventory accuracy, productivity and order status.
• Build accurate billing data extracts for storage, handling and value-added services to support client invoicing.
• Systems Integration, EDI and APIs
• Develop and maintain integrations between the WMS and Remco systems, including TMW, the EDI platform, Infios Labour Management, and client ERP and order systems.
• Build, map and test EDI X12 transactions with clients and trading partners, including 940, 945, 943, 944, 846 and 856.
• Develop, consume and test REST and SOAP APIs and file-based interfaces (XML, JSON, CSV, flat file).
• Coordinate integration testing with trading-partner IT representatives and implement maps and interfaces into production.
• Monitor interfaces daily, resolve failures and data errors quickly, and report recurring issues to the WMS Project Manager.
• Support integration with RF devices, label printers and material handling or automation equipment as required.
• Testing, Deployment and Support
• Write unit tests and test cases, and support SIT, FIT and UAT, including test scripts and test data.
• Prepare release notes and deployment steps, and support go-lives, client launches and site cutovers.
• Provide second-level support for WMS incidents, including root cause analysis and permanent fixes. Take part in after-hours support for go-lives and critical issues.
• Regression-test and retrofit custom code for vendor upgrades and patches.
• Document product defects with technical detail for escalation to Infios, and work with the vendor through resolution.

Requirements, Documentation and Collaboration

• Gather requirements from operations and clients, translate them into technical specifications, and provide effort estimates.
• Maintain technical documentation: design specifications, code and configuration notes, integration maps and support runbooks.
• Crosstrain IT team members on custom solutions to reduce dependence on anyone.
• Other related duties as assigned.

Requirements and Qualifications

• Knowledge of warehouse processes in a multi-client 3PL environment, from receiving to shipping, including inventory control, labelling and billing.

• Experience across the full software development lifecycle, from requirements and design through testing, deployment and support, in Agile or waterfall projects.
• Strong analytical and troubleshooting skills, including working with complex data and resolving production issues under time pressure.
