We build, develop and maintain massive scale, highly performant REST/GraphQL API services, backend-for-frontend services that enable ease of client application development and our success is the difference between millions of happy customers or millions of missed opportunities. \n \n ⁃ We are building systems to solve real world problems at scale, impacting tens of millions of \n ⁃ Teams of great Engineers (and Managers and Product Managers) to learn from \n ⁃ We are agile and enlightened in our approach to building software and teams \n ⁃ There’s a great atmosphere and we work sustainably as a team \n ⁃ Tesco has a “do the right thing” mentality \n ⁃ We promote flexible working \n \n Job Responsibilities \n \n • Use your in-depth knowledge of JavaScript, Typescript, Node.JS, cloud and the backend services ecosystem to develop, and deploy scalable backend systems. \n • Work with product managers to understand business/product requirements. \n • Translate requirements into tasks & code. \n • Commit code early and often, demonstrating understanding of version control & branching strategies. \n • Automate everything by default. \n • Write secure code by default. \n • Write maintainable code and observe basic hygiene practices \n • Implement relevant project instrumentation. \n • Profile and optimise code. \n • Apply understanding of cohesion and the SOLID principles to create well structured, maintainable software. \n • Identify patterns in code and refactor the code towards them where it increases understanding and/or maintainability with minimal guidance. \n • Produce test driven features in a specific programming language and demonstrate familiarity with the TDD development. \n • Follow the best practices of continuous BDD/TDD/Performance/Security/Smoke testing. \n • Work effectively with product stakeholders to communicate and translate needs into product improvements. \n • Lead group discussions on system design and understand domain well enough to work with Product Managers to drive value. \n • Support production systems, resolve incidents and perform root cause analysis. \n • Debug/find complex problems and support/maintain the software solution. \n • Share knowledge with the wider engineering community. \n • Mentor and develop others around you. \n • Produce proof of concepts to evaluate new tools. \n \n You will need \n We are looking for people who have a passion for Technology. You will demonstrate experience of different platforms and technologies. We expect to see some or all of the following: \n ⁃ 7+ Years professional experience as a Backend Software Developer. \n ⁃ At least 4 years of experience in backend development using Javascript, Typescript, Node.JS and related backend technologies, frameworks. \n ⁃ Exposure to a variety of JavaScript frameworks and libraries such as: Next.JS, React.JS and testing using Jest, Mocha.JS, Cucumber etc. \n ⁃ Experience of using Node.js to create high traffic applications using Express.js, Sails, Koa or similar. \n ⁃ Knowledge of microservices development and deployment in the cloud i.e. Azure/AWS/GCP cloud. \n ⁃ Knowledge of virtualization, containerization and container orchestration technologies like Docker, Kubernetes etc. \n ⁃ Experience with usage of GraphQL, building GraphQL servers and GraphQL Federation technologies like Apollo Federation. \n ⁃ Experience with using and building REST API services. \n ⁃ Knowledge of distributed messaging systems like Kafka, RabbitMQ etc. \n ⁃ Knowledge of distributed caching technologies like Redis. \n ⁃ A desire to write readable, maintainable, modular and extendable code. \n ⁃ Exposure to the DevOps model. \n • ⁃ Experience in Lean and Agile environments and understanding of principles behind methodologies such as: BDD, ATDD and TDD. \n
