UK-based e-tailer Ocado is on the hunt for 100 software engineers, technology professionals and technicians to aid the business's expansion at home and abroad, it was announced today.

The online grocer's technology division is currently searching for "the brightest tech talent" to work on robotics, machine learning, cloud development and big data at its Hatfield facility.

Jobs available at the technology division are part of the retailer's wider campaign to recruit around 1,000 new people in the UK – its biggest ever recruitment drive – which includes 800 vacancies for personal shoppers at the company's customer fulfilment centre in Dordon, Warwickshire.

As online shopping grows in popularity and Ocado's sales continue to rise, there is a requirement for more staff to receive, pack and load customers' orders. Other vacancies are available at Ocado's brand new hub in Ruislip and in the customer service team at Wimbledon, as well as various head office roles.

Julie Markey, HR director at Ocado, commented: "In just a few short years Ocado has grown from a tiny start-up to a company worth over £2.5 billion and we’re delighted to announce the creation of 1,000 new jobs as we continue to develop our business here in the UK and abroad.

“Every role is critical to our success, from keeping our website running smoothly, to packing groceries and delivering them into our customers' kitchens."

In March, Ocado published an interim trading statement showing encouraging first-quarter revenue growth.

Group sales at the grocer in the 12 weeks to 23 February 2014 totalled £227.5 million, which was an increase of 22.6% year on year. Meanwhile, average orders per week had grown by more than 18% to 155,152.
