About Us

At 🟣 Purple Dot, our vision for e-commerce is simple: Everything that gets made, gets sold.

Nearly 1 in 4 products is never sold - resulting in major losses and massive waste within the industry. We believe this problem exists because of lack of control and flexibility over when brands can sell - with long, fixed timelines where brands have to wait until stock is at the warehouse to start selling. It’s time for a radical shift in how e-commerce operates.

Purple Dot is pioneering the pre-commerce category: helping brands sell earlier - before inventory arrives - to increase sell-through, reduce waste, and drive profitability. Whether stock is 1 day or 1 year away, our platform enables smarter, faster sales that reduce risk and unlock new growth.

Trusted by over 100 leading brands including Mattel, McLaren, New Era, Limited Run Games, and Oh Polly, we process tens of millions in pre-orders every month and are proudly leading the category out front. Backed by top investors like OpenOcean, Connect, and Unusual Ventures, we’re a 22-person team based in London, NYC and Charlotte - and led by second-time founding team with a track record of acquisition.

The Job

Extending e-commerce with Purple Dot is technically complex and exciting!

• High concurrency
  • We need to handle massive, sometimes unpredicted spikes in traffic that must not result to oversell (e.g. when one of our customers run a surprisingly popular launch of a new collection, our system went from <1 to 80 checkouts/second (800k req/s at CDN level) in less than a minute.
• Complex state machine
  • We need to manage the lifecycle of pre-orders across many disparate third-party systems (ERPs, OMSs, 3PLs, Shopify, Stripe).
• Different use cases
  • Pre-commerce solves many different problems for our customers, but that in turn means our customers use Purple Dot in different ways.

As a Senior Full Stack Engineer, your goal is to grab ideas for new features for our pre-commerce platform and turn them into reality, as quickly and with as much quality as makes sense at the time.

• True Autonomy
  • We don’t have a frontend/backend/infra split, you will be architecting solutions end-to-end, not just moving Jira tickets across a board. You will work on all shopper and merchant facing features of Purple Dot.
