About the Role:

Lead Engineer

Holland & Barrett International is striving to be the world's leading health and wellness business. Currently the largest in Europe and growing in other markets, the health and wellness of our colleagues and customers is at our heart.

Technology at H&B

We're on a mission to make health and wellness a way of life for everyone – and technology is at the heart of our future to become a leading omni-channel retailer. We're building some great products, and we're investing in the rapidly advancing technology that is helping our customers meet their health and wellness goals. We're delivering more speed in the retail experience, greater convenience in service and delivery, and increasing personalisation in our brand and product propositions, both in-store and online.

Collaborative, working at pace and always with a strong customer focus in everything we do. We love the cloud, we prefer building the right solutions over buying generic ones, and we embrace automation and testing in all thing's software, infrastructure, and data.

 

The Role

The position sits within our Retail vertical and specifically our Stores Tills Team.

In 2019 we decided to build rather than buy our till systems.  We built our V1 from scratch based on what stores and colleagues were already used to and that would run on our old existing hardware.

This was done in a true agile (with a small a) way.  It's a big challenge and a critical piece of software that our colleagues use.  We started small 1 till in 1 store, got feedback, improved, and scaled up to the whole estate in UK, Ireland, Netherlands, and Belgium.

Since 2019 we've processed over £1bn worth of transactions in 4 countries and 2 currencies. We've added additional features like Click & Collect integration, loyalty sign up at the till point and order in store – where a customer can order items to be shipped to home or the store at the till point.

Four years on we've just purchased some fancy new hardware, and we're rolling out a major update (V2 of the system) to make use of it.

 

This is a lead role and covers the full stack in the true sense.  It covers the till application itself, some backend api services, reporting systems and some operating system maintenance.

  • Integration to hardware – think serial ports to receipt printers and barcode scanners.
  • Integration to apis – like loyalty, stock etc.
  • A complete reporting suite for operational reports stores use to look at their sales and performance.
  • Own issues and drive solutions to problems.
  • Support what we build.
  • Build our own tooling for debug, support, and monitoring.

There's a large amount of autonomy and collaboration.  This is most definitely not a ticket factory role.  It sounds cliché but we do work a bit like a startup.  We've built a great reputation amongst colleagues in store using our tech as well as our peers in the head office.  We're a small team working on the till side of things, but we form part of the larger InStore team for social and collaboration.

You will sometimes need to visit stores to observe tills in use, get feedback from stores about an issue, try out new ideas and generally just meet our users.

We want you to become the ‘go to' person for anything related to the till system.

Everything we build we put the customers and colleagues needs at the forefront of our decision making. Engineers will be involved in understanding current store journeys customers have and how that experience can be enhanced whether by the technology directly or by supporting the colleague engaging the customers.

We are on a multi-year transformation moving away from both legacy tech and legacy processes to truly embrace our vision of what our store experience can be.
