Senior Software Engineer (GraphQL) (2 days office, 3 days WFH)


Job Purpose
To help design and build the GraphQL OSP Flex Headless Commerce Proposition in collaboration with the Ecommerce stream

Roles & Responsibilities
Proposed Mission: Provide a world class GraphQL headless commerce solution that provides the best of OSP Ecom and allows our retailers to integrate and innovate with OSP in ways we have not imagined before

Goals for the first 6 months:

  • Enable retailers to integrate OSP with 3rd Party recipe apps
  • Allow a full shop and delivery to be completed on OSP just via our GraphQL API's
  • Help the team plan and prioritise the future goals and roadmap for Headless

The team has an ambitious goal enhancing the OSP offering by providing a GraphQL Headless Commerce Solution on top of OSP. This will unlock 2 areas of potential for OSP:

  • Sign new deals with retailers where control of the UI/UX is key to them but they want all the benefits that OSP offers.
  • Enable our existing retailers to use and integrate OSP more directly into their business in new and interesting ways.
  • In order to achieve this we will need to work closely with all teams across ecommerce to help define and implement a single suite of APIs so we can present headless as a single product to prospective and current clients.

Initially you will be responsible for working with the team and Product Manager to:

  • Design and determine the GraphQL Schema we need to build in order to achieve our goals
  • Design and determine the scope of the GraphQL schema we need to build to deliver the project
  • Work with the domain teams to agree and finalise those designs
  • Develop the resolver endpoints inside the domain teams systems in collaboration and sign off by those domain teams of the work being done.
  • Externalise these endpoints
  • Support domain teams in designing Headless GraphQL APIs in their own systems if their roadmaps and time allow for it

What we're looking for: 

  • GraphQL API Schema Design Knowledge and Experience
  • GraphQL performance management and monitoring
  • Java
  • Ability to effectively facilitate discussions across a range of API design topics within the team and other eCommerce teams, and the ability to communicate and engage others around the decisions made in the team.
  • Strong collaboration skills that will allow you to work effectively alongside teams across all the departments inside of Ecomm and across the business

It would be nice to have:

    • Familiarity with ecommerce flows
    • Experience around building GrpahQL APIs for external consumption
    • Modular Architecture and Design experience

What we can offer you:
