Tophatter is a mobile e-commerce marketplace. We've taken the most exciting part of eBay - the last minute of every auction - and built a product experience around that. All items on Tophatter are put on auction and the average time an auction lasts is 90 seconds. This creates a fun, addictive online shopping experience.

Engineering at Tophatter
Engineering team and processes

Each quarter, we break into teams of 3-4 engineers and a product manager. Each team is given an area of focus (e.g. onboarding, buyer experience, retention, personalization, supply, internationalization, and security). The team works together to define goals for the quarter and a prioritized list of projects that they hope will achieve those goals. We do a lot of A/B testing to see what works and what doesn't.

Technical Challenges

(1) Dealing with the large scale of real-time auctions

(2) Creating an engine that automatically determines the best products to run on the site at any given time

(3) Personalizing the site / emails / push notifications for each user

(4) Handling our large quantity of analytics data

Projects you might work on
  • Acquisition

    How can we spend the next $100 million in marketing better than the last? We’re building the infrastructure to automate and optimize our marketing efforts so that we can scale our spend while decreasing the CPA (cost per action).

  • Buying Formats

    We’re experimenting with news ways to sell products on Tophatter. Are there different ways to help users discover different types products that they are looking to find?

  • Return Buyer Experience

    How do we know what our shoppers want before they do? Tophatter is a discovery shopping platform and we’re actively working on delivering a personalized experience to delight every shopper. Projects range from improving product recommendations to user-facing features.

  • Supply Optimization

    We solve a complex supply and demand equation when dealing with a two-sided marketplace with auctions — we can’t oversaturate our supply compared to our demand because then items will sell at too low of a price, leaving sellers unhappy.

  • Risky Business

    We’re focused on eliminating or reducing sources of business risk to Tophatter. Improving how we fight fraud, staying ahead of security issues, making sure our application and infrastructure is resilient to failure and disaster recovery are some of the things we work on.
