Wayfair Careers

Senior Simulation Engineer

Boston, MA
Analytics - Operations Analytics

Job Description

The Wayfair Operations Research team is seeking a Simulation Engineer to help optimize its current supply chain network and simulate the future state of the network by ingesting internal and external data sources, applying advanced modeling and simulation methods, and presenting implementable options and recommendations. They will help develop a model of the supply chain network that represents the current state and then help identify areas for improvement, and ultimately ensure that Wayfair products take the fastest and most cost-efficient path to our customers. They will leverage a deep understanding of principles of simulation, statistics and optimization and their application to solve business problems.

Ideal candidates will be collaborative, results-driven and data-centric with a focus on quality and speed of execution.

Responsibilities include, but are not limited to:

  • Build simulation models of network flows and building flows using commercial-off-the-shelf simulation software - model individual components like warehouses and cross docks and processes like receiving freight, putting freight on racks, and picking orders in waves using different types of equipment or conveyance
  • Gather and validate requirements and input data
  • Perform value-stream analyses through the use of simulations
  • Contribute to developing a decision-making framework with quantifiable tradeoffs for the entire order fulfillment process including supply and demand planning, process design, and throughput improvements
  • Optimize supply chain network layouts by analyzing throughput capabilities, bottlenecks, inventory placement, and optimal routing
  • Develop a visualization framework to capture both high level network operations and detailed node-level operations and generate concise, clearly communicated analysis for stakeholders
  • Understand industry trends for simulation techniques and advance team capabilities



  • Degree in Operations Research, Computer Engineering, Industrial Engineering, Logistics or Supply Chain
  • 4+ years of experience in simulation and modeling 
  • Experience modeling complex logistics systems, material flow, and/or inventory systems
  • Experience building process flow simulation models with at least 1 discrete-event simulation tool, preferably Anylogic
  • Experience with designing, developing, testing and maintaining scalable analytical frameworks for evaluating business decisions
  • Manage simulation frameworks to provide recommendations to stakeholders to make decisions about Wayfair infrastructure and processes for the near-term and long-term
  • Experience with languages like Java, Python or SQL along with a familiarity with source code version control (e.g. Git)
  • Experience with data visualization 
  • Knowledge of statistics, uncertainty, sensitivity analysis, design thinking, databases, systems, algorithms and Monte Carlo methods
  • Communicate effectively with operations leads, planners, industrial engineers, product managers, and engineers
  • Ability to work independently in a highly variable and fast-paced environment
