The Amazon Customer Excellence System team (ACES) is seeking an enthusiastic, data-
driven, and technology-minded Process Owner to contribute to country expansion.
The ACES PSE (Process and Systems Engineering) is a team of Process Owners with the
mission to support Fulfilment Centre (FC) & Inbound Cross-Docking (IXD) process improvement
on behalf of Amazon customers. As the intermediary between operations and software
teams, our team is responsible for project execution, process maintenance and
troubleshooting, and change management for new hardware and software deployments in
our FCs & IXDs. We own the virtual process setup, software, and equipment standardization
and design & rollout of software projects. We define launch standards and provide end-to-
end support for new FC/IXD launches and ad-hoc FC/IXD process support. Our vision,
together with the Amazon Fulfilment Technology team, is to develop efficient and reliable
systems enabling our operations teams to process and fulfill customer shipments on time
and free of defects.
This role sits at the heart of space management and slotting program — a transformational shift in how Amazon
fulfillment customer orders across. As the Space Process Owner, you will be the go-to expert for one of the most operationally impactful processes in the FC network: the
systematic assignment of ASINs to optimal storage locations. Slotting directly determines
picking efficiency, replenishment frequency, transfer cancellation rates, and labour
productivity across the entire network. You will be building this capability from the
ground up for the country, drawing on other regions learning while shaping a uniquely country model.
A successful candidate will work in partnership with existing Process Owners and the
worldwide Subject Matter Experts (SME) network towards the design, development, and
tactical execution of slotting process improvement plans and new product development
plans.
This role requires the ability to travel up to 40% of the time.

Key job responsibilities
Be the Operations Customer Fulfilment network's 'go-to' subject matter
expert for space management operations across the FC network
operations
 Own the end-to-end weekly space management execution cycle — optimization runs to validating outputs, aligning on
site relocation capacity, and monitoring transfer cancellation metrics daily
 Influence strategic goals by shaping the technical vision and roadmap for space management
through idea scoping, business analysis, prioritization, and robust planning —
including driving the AFT space management improvement roadmap toward automation and
hands-off-the-wheel execution
 Write compelling business proposals for a cross-functional audience of senior
leaders and experts
 Track and report space management and slotting performance metrics including transfer cancellation rates,
replenishment picked by NBD, and slot utilization, identifying trends and driving
corrective actions with site operations
 Drive cross-functional discussions with AFT, Supply Chain Execution, SCOT, and
Category Supply Chain teams by providing operational data, site-level feedback, and
execution insights that inform space management process improvements. Identify
opportunities to improve slotting accuracy, reduce manual intervention, and
contribute to the long-term automation roadmap in partnership with technology
teams
 Create standards for space management and slotting processes and training materials in collaboration with
the Learning & Development team, to secure a high level of knowledge within FC
and IXD operations
 Collaborate with the extended ACES teams to define process standards and
metrics meeting daily and seasonal operational needs, including event-driven ASIN
additions for Prime Day and Holiday peaks
 Build a network with worldwide teams to share knowledge and identify and
implement best practices across the region and network, including formalizing the
transition of business-as-usual execution to other org once operational stability is
achieved

A day in the life
As a Process Improvement Expert, no two days are the
same. You will be at the centre of a fast-moving program that is redefining how Amazon
operates Customer Fulfillment. In the morning, you might be analysing transfer
cancellation metrics and running constrained slotting scenarios to align with site relocation
capacity. By afternoon, you could be validating space outputs with site operations or
coordinating catalogue attribute fixes with Retail and Quality teams. You will balance
weekly execution cadence with ad-hoc operational challenges, coordinating across site
operations, supply chain, and technology teams to keep slotting on track. Beyond
execution, you will identify patterns and gaps in the space management and slotting process that drive continuous
improvement, working with partners to refine workflows and reduce manual touchpoints
over time. Your role is to keep the space and slotting engine running while building the foundation for
a more automated and scalable process.

About the team
Amazon Customer Excellence Systems (ACES) team plays a critical role in orchestrating
cross-functional technology and continuous improvement projects from scoping and
design to test and rollout. The team plays a vital role in integration and communication
between the Amazon Technology Teams, Fulfilment centre (FC) and Inbound Cross-Docking (IXD)

Our goal is to design autonomous and automated systems to replace complex decision-
making with simple solutions and facilitate end-to-end operational control of fulfilment
execution. Within this mission, the Slotting role is a flagship initiative — you will be
establishing slotting capability from scratch, working at the intersection of operations,
technology, and supply chain to unlock the full potential of the FC network.
