Senior Software Engineer

As a Senior Software Engineer at Holiday Extras you will play a key role in solving some of the most exciting and challenging problems the travel industry has right now. The biggest one is how we remove the unnecessary hassle from travelling so our customers can make the most of their precious holiday time - in fact, the whole reason why we exist.

We believe all the answers lie in creating pioneering tech for our customers.

This is where you come in…

We're looking for Senior Software Engineers to drive our move to a microservices and API based architecture.

In this exciting time for travel, we're on a mission to remake holidaymaking. So we're on the search for people in a variety of streams to help make this happen - whether you like to see your code directly improving the customer experience on our app, mobile or desktop platforms or you prefer to be shaping the backend architecture, with continuous integration you'll be able to have an impact immediately.

Our current streams of work include:

  • Intelligent Recommendations - Creating and developing data models with our data science team to create a super intelligent recommendation engine. Leveraging data we have about our customers, their trips and the travel market to create customer value in HEHA! (our Holiday Extras, Holiday Assistant).
  • Service - Making it easy for our customers to self-serve on our site and app by providing a first-class chat experience that uses Machine Learning to present fast, automated-responses. Our goal is to have the best chat experience online where customers get their queries answered swiftly and when needed can connect with a member of our service team either via chat or over the phone if required.
  • Supply - Connecting with our supply partners to deliver the best product, price and availability. We integrate with multiple partners who are at different stages of their tech journey. We're currently building out our best-in-class integration strategy overcoming challenges of storing and presenting millions of prices across multiple product types. Focus is on speed and accuracy.
  • Moving all traffic to our most performant booking platform - We call it the Trip App; our modern Single Page web application built with React. We are constantly empowering our engineers to use the best and latest tech and coding standards. Trip App has a good use of code-splitting, hooks, redux, great test coverage and more. This gives our customers the most seamless experience and our developers the best possible coding environment to work with.
