The Simulation Engineer, for Fulfillment Engineering is primarily responsible for conducting detailed simulations along with the advanced data-analytics associated with Walmart e-commerce fulfillment network (including Walmart sortable, Walmart Non-sortable, Jet Sortable, Jet Fresh, Sam’s Club, Hayneedle, Shoebuy, etc.). Your ultimate goal is to provide deep insights into the interaction of complex fulfillment processes and designs with the goal of quantifying how these processes affect the Variable Cost Per Unit (VCPU) and Total Cost Per Unit (TCPU) for the entire Walmart E-Commerce Fulfillment Network.
Challenges you’ll be tackling
Building Detailed Simulations: You will be responsible for building detailed DES/Agent/Process based predictive models to identify the bottle-necks with current operations and to test/iterate and validate the designs for future fulfillment centers
Data Analytics: Output of every model are a bunch of numbers. Numbers used incorrectly can lead to worse decisions than using intuition or experience alone. As the simulation expert, you will be responsible to define, clean and analyze the input and output data from your models to the stake-holders.
Ensuring zero-defect analyses: Errors in datasets are inevitable, so you will work collaboratively with field engineers and on-site management and associates to ensure data integrity and validate correct conclusions.
Collaboration is vital: It takes a village to build a good model. You will be responsible to work with cross-functional partners (operations, design teams, inventory managements, strategy, analytics, finance) to define inputs (data, design, process) to the model along with the key KPIs for the project. Engaging with these cross-functional teams at every stage of modeling process is necessary for the success of the project.
Communication is Key: Solving a complicated problem adds little value if it is not communicated in an effective way. Every model has assumptions and too much data can be overwhelming or paralyzing, so you will distill the most salient information for each audience, from design engineers to simulation scientists to business analysts to senior leadership. A key part of this will be to build visually appealing 3D models, dashboards and associated reports
Predicting the future: Basing future designs and processes exclusively on data from existing designs and processes is inherently limiting, so you will extrapolate and make responsible assumptions to support out-of-the-box next gen designs and ideas. As such, you should be comfortable with advanced multivariate statistical methods to crystalize complex data.
How you’ll know it’s right
Judgment - Make Sound Judgments - Uses objective financial and business analyses to evaluate the returns and risks of design or process choices. Analyzes and integrates trends and patterns to determine the root causes of problems and identify solutions. Evaluates short- and long-term implications of decisions. Accurately forecasts growth, costs, and business challenges. Identifies and applies sound, fact-based criteria in setting priorities and making decisions. Looks beyond symptoms to determine the root causes of problems, and identify and implement applicable solutions. Integrates knowledge and expertise in making fact-based recommendations and decisions.
Influence and Communicate - Develops and communicates logical, convincing justifications, including lessons learned, that build commitment and support for one's perspectives and initiatives. Builds diverse, high-performing teams that accomplish organizational changes, goals, and priorities. Develops vision and strategy that is clear and easily articulated. Ensures strategies, change initiatives, and competitive information are communicated in clear and compelling ways. Listens to, leverages, and promotes the diverse ideas, perspectives, and contributions of others across the business.
Execution and Results: Ensure Execution and Achieve Results - Conveys a sense of urgency to complete and achieve goals. Pursues the achievement and alignment of measurable and meaningful goals. Prioritizes and balances time, actions, and projects to ensure accomplishment of results.
Adaptability: Demonstrate Adaptability - Demonstrates resourcefulness and resilience in the face of change, obstacles, and adversity. Adapts to competing demands and shifting priorities. Updates knowledge and skills to handle new complexities, challenges, and responsibilities (for example, seeking out training, learning from experience, researching best practices, new emerging technologies and companies that can be leveraged for future solutions). Seeks exposure to new ideas and perspectives. Sponsors programs and initiatives to improve adaptability and continuous learning capabilities in own organization.
Build Relationships: Build Internal and External Relationships - Builds and sustains trusting, collaborative relationships and alliances across functional, organizational, and geographical boundaries to achieve goals. Sponsors initiatives and programs that promote respect for, interest in, and support of associates. Ensures associates are treated in an accepting, respectful manner.
