Implementation Manager

We are Manifest.eco, a high-growth, sustainable third-party logistics start-up, shaking up the fulfillment industry by offering eco-friendly logistics solutions for eCommerce brands and pioneering Third Wave Fulfillment.

At Manifest, we believe that our Product is order fulfillment and the white-glove service that supports it. We focus most on what’s fundamentally important to our growing brand and design, implement, and deliver solutions to meet those needs.

Implementation, or the onboarding of new accounts, is critical to facilitating success of our partnerships with brands, both at the onset as well as long term.

The Implementation Manager role supports this mission by executing high-quality, repeatable onboardings in close partnership with the Head of Implementation. This role reports directly to the Head of Implementation and plays a key role in delivering the onboarding experience as designed.

The Implementation Manager supports Manifest’s onboarding “triple mandate” by assisting with:

• Sales Engineering: supporting the translation of merchant requirements into clear technical and operational plans in collaboration with Sales and the Head of Implementation
• Technical Implementation: executing technical implementation between merchant storefronts, ERPs, and Manifest’s internal systems to support successful outbound shipping launches
• High-Touch Early-Stage Account Support: acting as a primary point of contact for merchants during onboarding and early shipping to ensure a smooth transition prior to graduation to Account Management

The Manifest Implementation Manager is highly organized, technically capable, and execution-focused, with a strong ability to communicate clearly with merchants and internal teams. The ideal candidate is a proactive problem solver who can operate effectively even when all of the answers are not immediately clear.

The Implementation Manager will develop an intimate familiarity with physical warehouse operations, particularly as they relate to the prescriptive workflows of our warehouse management system (WMS), Ship Hero. They will also develop hands-on experience with merchant software platforms including online storefronts (e.g. Shopify), inventory management systems and ERPs (e.g. Net Suite), EDI platforms for wholesale (e.g. SPS Commerce, Orderful), and other middleware connecting Manifest systems with merchant technology.

The Implementation Manager works two days per week in our San Marcos, Texas fulfillment center and three days per week remote. They report directly to the Head of Implementation
