  • WMS Manager / WMS Lead
  • Supply Chain Systems Manager or Director of Warehouse Systems
  • IT Project Manager for Logistics/Distribution Technology

Lateral Moves:

  • ERP Functional Analyst (SAP, Oracle)
  • Business Systems Analyst (Supply Chain)
  • 3PL Operations or Network Optimization Specialist

Core Responsibilities

Primary Functions

  • Lead end-to-end WMS implementation projects including requirement gathering, process mapping, gap analysis, system configuration, data migration, cutover planning, and go-live support to ensure timely, on-budget deployments that meet warehouse SLAs.
  • Configure WMS modules and features (inbound receiving, putaway, inventory management, cycle counting, replenishment, picking strategies, packing, and shipping) to reflect operational best practices and drive inventory accuracy improvements.
  • Design and implement picking and packing workflows (wave, batch, zone, cluster, pick-to-light, put-to-light) and optimize pick path logic and slotting rules to reduce travel time and improve order cycle time.
  • Integrate WMS with ERP systems (SAP, Oracle, Microsoft Dynamics), TMS, OMS, EDI gateways, and 3PL systems using APIs, flat files, middleware, or EDI to enable real-time inventory visibility and automated order flows.
  • Develop, maintain, and execute complex SQL queries, stored procedures, and ETL processes to extract, transform and load inventory and transaction data; validate data migration and reconcile stock during deployments.
  • Build and maintain reports and dashboards using tools such as SSRS, Power BI, Tableau, or Crystal Reports to track KPIs including order accuracy, cycle count variance, dock-to-stock time, pick rate and on-time shipments.
  • Troubleshoot production issues and perform root-cause analysis for WMS incidents, managing tickets through ITSM tools and coordinating with infrastructure, network, and vendor support to restore service within SLA.
  • Manage WMS upgrades, patches, and release cycles—conduct regression testing, performance testing, and coordinate business UAT to minimize disruption to warehouse operations.
  • Create and maintain detailed system documentation: configuration guides, data dictionaries, process flows, interface specifications, test scripts, and go‑live checklists for auditability and knowledge transfer.
  • Lead user acceptance testing (UAT) and build test scenarios that reflect real warehouse edge cases (partial receipts, cross-dock, returns processing, backorders) to ensure robust system behavior.
  • Provide Tier 2/3 WMS support including diagnosing barcode/RF scanning issues, label/template updates, print and device configuration, and mobile RF application troubleshooting.
  • Implement and maintain barcode labeling standards, print formats and RFID policies to ensure traceability across receiving, putaway, inventory adjustments, and shipping processes.
  • Partner with operations leadership to design and roll out continuous improvement initiatives (Lean, Six Sigma projects) enabled by WMS capabilities—measure results and iterate on system and process changes.
  • Configure and maintain user roles, security rights, and segregation of duties within the WMS to protect inventory integrity and meet internal control requirements.
  • Coordinate with 3PL providers and warehouse partners on WMS integration, SLAs, cutover plans, and data exchange requirements to support outsourced warehousing or multi‑site inventory models.
  • Conduct regular cycle count strategies and physical inventory reconciliations—investigate variances, identify systemic root causes in WMS or processes, and implement corrective actions to reduce shrink and improve accuracy.
  • Design and optimize replenishment logic, buffer levels, and safety stock settings in the WMS to balance service levels and working capital across high-turn SKUs and seasonal demand.
  • Create technical interface specifications and manage file formats for EDI 856/850/940/945 transactions, XML/JSON APIs and custom middleware to ensure accurate order/ASN/invoice flows.
  • Provide hands-on training and develop role-based curricula, quick reference guides, and classroom/virtual training sessions for warehouse users, supervisors and support teams to accelerate adoption.
  • Monitor system performance and transaction throughput, analyze bottlenecks, tune database queries, and work with DBAs and infrastructure to optimize WMS performance during peak volume periods.
  • Drive change management by partnering with stakeholders across operations, procurement, transportation and finance to prioritize WMS developments, feature requests, and roadmap items that deliver measurable ROI.
  • Validate and enforce compliance with regulatory and customer requirements (lot/serial tracking, expiry management, temperature-controlled storage, customs documentation) using WMS controls and reporting.
  • Manage relationships with WMS vendors, implementation partners and integrators; evaluate vendor patches, manage escalation, and negotiate support/resolution timelines.
  • Develop acceptance criteria for automation technologies (conveyors, sortation, pick-to-light) and lead WMS integration efforts with automation vendors to coordinate control logic, PLC integration and operational testing.
  • Prepare post-implementation reviews, lessons learned, and continuous optimization plans to capture knowledge and reduce future project risk.

Secondary Functions

  • Support ad-hoc data requests and exploratory data analysis to answer business questions tied to throughput, labor efficiency, and inventory health.
  • Contribute to the organization's data strategy and WMS roadmap by recommending modules, features and integrations aligned to business goals.
  • Collaborate with business units to translate operational needs into WMS configuration, customization, and technical requirements.
  • Participate in sprint planning and agile ceremonies within the data engineering and IT teams to prioritize WMS backlog items and track delivery.
  • Assist procurement and vendor management teams with technical evaluations and RFIs/RFPs for WMS enhancements or third‑party integrations.
  • Support disaster recovery and business continuity planning for WMS operations, including rehearsal of failover and data restore procedures.
  • Mentor junior WMS analysts, share best practices, and help build a center of excellence for warehouse systems and automation.
