Junior Data Engineer in London

The Wonderfield Group has recently been purchased by Zensho Holdings, the leading food service company in Japan with a market cap of $5.5b and whose aim is to become the world's largest food company, a position from which we can eradicate hunger and poverty from around the globe. We operate restaurants, factories, and thousands of sushi kiosks and have recently built a successful cut fruit business, Snowfruit. Combining this with the three businesses previously owned by Zensho, AFC, Sushi Circle and Sushi Take, results in annual sales of $2.5b and Ebitda in excess of $140m a year with an ambitious growth trajectory.

Can be relied upon to work proactively - we require a candidate who doesn't need to be told what to do and takes responsibility for ensuring they are busy and productive. Candidates who would prefer to be less busy need not apply. Takes ownership - Data Engineering is often about fixing processes that are broken before anyone else notices; the successful candidate will demonstrate a willingness to identify and fix problems without input from other people. Strong attention to detail - details matter in Data Engineering and we want a candidate who will go above and beyond to ensure that their development is consistent and well organised. Pride in work undertaken is important. Flexibility and humility - essential for good team working. Can demonstrate a detail-oriented mindset and a genuine interest in computer-related problem solving (development, scripting, PC-building and performance tuning, electronics etc).
