We have been exclusively engaged by a well-established retail and consumer brand known for its strong market presence, loyal customer base, and continued investment in technology to support growth and operational excellence. They are hiring a Senior Systems Engineer focused on Manhattan Warehouse Management Systems (WMOS) to play a critical role in supporting and stabilizing a core fulfillment platform, while also positioning the business for a future transition to a modern WMS environment.
This is a unique opportunity for someone who enjoys being the go-to expert in a high-impact system, where your work directly supports day-to-day operations, while also giving you a seat at the table for a major WMS modernization initiative in the near future.
This is a full-time, direct hire role that is primarily remote, with occasional travel to their headquarters outside Philadelphia, PA tied to key projects and system initiatives.
The Role You’ll Play
This is a hands-on, techno-functional role centered around supporting, configuring, and enhancing a Manhattan WMOS environment. The focus is on keeping the system running smoothly, solving problems as they arise, and supporting business-driven changes, not building brand new applications from scratch.
You will work closely with a small, collaborative team and act as a subject matter expert for WMS, helping bridge the gap between operations, IT, and external vendors.
What You’ll Be Responsible For:
Serve as a primary technical resource supporting Manhattan WMOS (version 2015) in a production environment.
Troubleshoot and resolve production issues across warehouse and fulfillment operations
Perform system configuration and updates, including codes, workflows, and system behavior
Support integrations and message flows using Manhattan Integration Framework (MIF)
Write and analyze SQL queries for troubleshooting, reporting, and validation
Partner with business users to support operational needs and system improvements
Assist with new partner onboarding and integration efforts (e.g., new retail or fulfillment channels)
Work with vendors, including Manhattan support, to resolve complex or escalated issues
Support testing, validation, and deployment of system changes
Document system processes, configurations, and issue resolutions
Ensure systems and processes align with SOX compliance requirements, including the ability to clearly explain system behavior to auditors
Contribute to planning and future-state discussions around WMS upgrades and modernization (Manhattan Active)
Background Profile:
This role is best suited for someone who has deep, hands-on experience with Manhattan WMOS and enjoys being in a role where they can own, support, and improve a critical system. You are someone who can troubleshoot issues independently, understands how WMS platforms operate under the hood, and can communicate clearly with both technical and non-technical stakeholders.
Core Requirements:
5+ years of hands-on experience with Manhattan WMOS (2015)
Experience supporting live WMS environments, including troubleshooting and issue resolution
Strong SQL skills for querying, analysis, and system troubleshooting
Experience working with Manhattan Integration Framework (MIF) or similar messaging/integration frameworks
Ability to support and modify system configurations, message flows, and integration templates
Solid understanding of warehouse, distribution, and fulfillment operations
Experience working in SOX-controlled or audit-sensitive environments
Strong communication skills, including the ability to explain technical issues clearly to business stakeholders and auditors
Preferred / Nice to Have:
Exposure to Manhattan Active or newer WMS platforms
Familiarity with Java-based WMS environments (no heavy development required)
Experience in retail, eCommerce, or distribution environments
Experience supporting ERP integrations and downstream system impacts
Experience working in small, high-ownership teams
