  • fulltime is the world's leading freelancing and crowdsourcing marketplace. We're a two-sided jobs marketplace with tens of millions of users worldwide. Every day thousands of jobs are described, bid on, negotiated, and managed through our site; you will be working with a dataset that details a real life economy.

We are a data-driven company: Data trumps opinions, every time. Every new feature gets A/B tested and analysed with our Bayesian methods.

You have a strong maths and/or stats background. You know how to take your code to O(log(n)), and when not to bother. You love to reach deep into a SQL dataset and pull out an interesting story. You dream in probability densities, not expectation values. You can smell a badly-designed experiment from a mile away.

You will work on a product team and be part of the decisions relating to your product. You'll be expected to scour the data for trends and potential opportunities, and design and analyse A/B tests. From time to time, you'll ideally surprise us and invent new and awesome ways to use our dataset to make the site better.

We currently have a dozen data scientists across three offices; you'll be collaborating with a team of PhDs and grads with backgrounds in Mathematics, Physics, Neuroscience, NLP, Computer Science, and Petroleum Engineering. But we're a growing company and need more brains.

Our dataset is well-organised in Redshift, and is maintained by a team of data engineers - so there's less wrangling required than in many DS roles.

This won't be your typical cog-in-the-machine type of job. You will be exposed to the fast pace of a rapidly growing global technology company. If you're a high achiever with talent, looking for something more than a boring job in corporate, want to work with the best and brightest, don't need to be handheld, and want to be in at ground zero with a company that has a shot at being one of the biggest sites on the internet then please contact us.
