Senior Frontend Engineer

What do we do?

ATG connects thousands of auction houses, listing millions of items worth over $15 billion annually (and growing!), to buyers in over 170 countries around the world. These buyers generate over 100 million bids a year for our sellers, helping them achieve maximum value for the goods they sell. We help auctioneers sell everything from medieval swords to combine harvesters, paintings and decorative art through to classic cars, furniture, and Caterpillar forklifts. We do this through 8 marketplaces that leverage our online auction technologies. We make auctioneers more efficient; we make small companies big by bringing them access to millions of bidders they could never find on their own, and we bring them technology they could never afford alone. We bring bidders choice of unique and specialized items, convenience, and trust. And we do it all in a shared success model that accelerates growth of the circular economy and sustainable buying. With ATG, our buyers and sellers win but so too does the planet! We have ethical ambition and it’s something our employees value and is a key part of who we are….as well as being a high growth marketplace company with excellent competitive positioning!
