Software Engineer - Operations Research

Wayfair
4 Copley Place - Floor 7
Boston, MA 02116

Who We Are (Operations Research Engineering):

Wayfairs Operations Research team is a mixed disciplinary team of Operations Research scientists and Software Engineers that are developing technological solutions for some of Wayfairs most complex optimization problems with an immediate impact on our operations. Our team comes up with creative strategies to develop and execute optimization-based solutions to keep Wayfair efficient as we scale. Many of our projects are in their infancy and do not have pre-existing solutions that overly constrain our approach or design decisions.

Our teams core areas of focus include:

  • Inventory management
  • Fulfillment center optimization
  • Order routing and fulfillment
  • Last mile routing
  • Network optimization

What you will be doing:

Your responsibilities will include automating large-scale batch processes, maintaining and improving performance of Python/Cython/C++ code, helping define best practices for maintainable code and processes, and working with other engineering teams to define APIs and integrate systems. Other projects and work include:

  • Working with Python web services, Spark (via PySpark), databases, caching systems, and other technologies.
  • Architecting a system to support the optimization of delivery truck routes and schedules to support order-in-cart for large parcel deliveries from our DAs
  • Generating replenishment proposals for hundreds of thousands of products stored in the Wayfair Stocking or Castlegate programs
  • Determining the selection of warehouses that will be used to fulfill small parcel orders to drive cost reduction, maintain inventory balance across our network, and increase 1- and 2-day delivery guarantees
  • Allowing interactive edits of Supplier Order Proposals and re-optimizing in real-time to respond to constraints and information not available during a batch run
  • Generating optimal pick lists and routes for warehouse personnel as they fulfill orders, and optimal positioning of products within a warehouse
  • Replacing commercial optimization software that no longer fits Wayfairs needs or scale

What youll need:

  • Strong math background / quantitative skills
  • Strong back-end programming ability
  • Familiarity with Python programming, expertise in Python is a plus
  • Comfort with agile software development as well as less predictable prototyping and research work
  • Proven ability to communicate cross functionally
  • Experience with large-scale distributed, parallel computation is a plus
  • Experience designing and implementing RESTful APIs is a plus
  • Knowledge of Python optimization approaches and technology is a plus
  • Familiarity with mathematical optimization techniques: linear and integer programming is a plus
  • Familiarity with Statistics / Probability is a plus
