\nConcrete Platform – Back-End Node.js Engineer \n\nLocation Farringdon London\n\nSalary £65k-£70k\n\nBenefits - We have a healthcare scheme, 25 days’ holiday and a flexible 2-day/week work-from-home policy.\n\nThe Role Concrete are looking to accelerate the delivery of our product feature roadmap for our new SaaS-based platform. To make these goals a reality we are expanding our engineering team, providing greater resources to reduce development times and enabling more projects to be worked on simultaneously.\n\nThe scrum team are responsible for building, testing and deploying all new back-end features to a Continuous Integration/Continuous Delivery pipeline, working predominantly in Node.js and ES6+ whilst utilising a range of modern tools including Docker, Kubernetes, Amazon Web Services and MongoDB. As work begins to ramp up, we are looking for an experienced Back-End Engineer to join our team and work closely with the Senior Engineers to ensure new features are completed at a consistent pace.\n\nBy providing an Agile induction we’ll get you up to speed very quickly and you’ll be actively involved in projects in no time, participating in team Scrum meetings and following a two-week release cycle within a Kanban work-management system.\n\nWorking as a Back-End Engineer you will be actively building APIs using Node.js with Express.js as a framework. Day-to-day, Node, Express and ES6+ (JavaScript) will be your bread and butter letting you take full advantage of the latest features and industry practices to create new Greenfield services, ensuring that our platform remains both scalable and future-proof.\n\nSupporting your daily work, you will utilise a diverse range of tools and services from the cutting edge of industry adoption. Using non-relational databases such as MongoDB, you will build queries and create tables, whilst using Kubernetes and Docker when deploying your code to Amazon Web Services (AWS).\n\nQuality is important to us, so you will take responsibility for the tech debt that you create: testing your own code and taking part in code reviews form a core part of the role. We currently use Jest for testing purpose and have a rigorous peer review process, helping to ensure that the code you create is always the highest quality possible. Once your code is signed off, you will merge it into the master branch, triggering, testing and orchestrating deployment into the Continuous Integration/Continuous Delivery pipeline.\n\nAs a company, we believe in fostering a supportive environment when you need it, but otherwise take a hands-off approach, giving you autonomy over your work. There’s already a great senior team in place, that is always happy to lend a hand. There may be times when you will work in a paired-programming environment alongside another engineer, but for the most part you will work independently from the user stories and materials provided.\n\n\nWhat we need from you You will, first and foremost, have a proven track-record in a Back-End Engineering role, working in an Agile product environment. We don’t mind whether you’ve worked as a web developer using open source tech or as a Java/C# engineer, so long as you’re excited by the prospect of moving to a JavaScript focused role moving forward.\n\nThe ability to write native JavaScript is crucial to the role, including a solid technical understanding of asynchronous programming in ES6+, enabling you to discuss how promises function and, ideally, how to use them in relation to the ‘async’ and ‘await’ functions.\n\nYou will have experience working independently, building APIs and features from scratch and generally working on the API-layer, including integrating APIs into pre-existing systems. Your level of knowledge should be sufficient to walk us through the lifecycle of a RESTful request, drawing on your own experiences and starting from the HTTP request all the way to testing end-points.\n\nWe work with MongoDB, but you don’t need direct experience. You should be able to explain why NoSQL databases would be used instead of relational databases (e.g. MongoDB/Couchbase instead of MySQL/PostgreSQL/SQL Server) We want someone who understands the fundamentals and is interested in learning more.\n\nThe ability to self-test your code will be critical to the role, so you should have a firm understanding of the benefits that this strategy brings. Your experience with testing tools (e.g. Jest, Jasmine, Mocha, JUnit, or even PHPUnit) will have left you with a strong understanding of why unit testing is important.\n\nOn top of that, you’ll also relish code reviews and recognise them as a feedback mechanism that helps both you and your team to improve.\n\nWe’ll expect you to have some knowledge of a Continuous Integration/Continuous Delivery (CI/CD) setup, including awareness of Docker and a basic understanding of DevOps skills.\n\nWe work in a collaborative environment and you will “Be Part of a Great Team”, so you should enjoy working closely with other team members. In particular, you must be happy to work paired with another engineer and should be able to discuss how this strategy can benefit your productivity, skills development and the integrity of the wider project itself.\n\nFinally, at Concrete we love what we do and expect you to be fascinated by every element of your job. You will be passionate about the front-end sector, getting stuck in to technical conversations whenever possible and will always be eager to provide your opinion, viewing challenges as a learning opportunity rather than a roadblock.\n\n\nWhat you’ll get from us A supportive and flexible learning environment, including great opportunities to gain new skills – or hone existing ones – with technologies that are rapidly becoming industry standards, particularly Node.js and the latest features of ES6 (JavaScript). You will be up-skilled as a priority with the aim to make you a truly full-stack engineer, including learning React and Redux on the front-end. We’re happy to adjust to your interests and strengths, so if you want to learn more about the front-end, Minimum Viable Products, Node.js or anything else, we’ll support you to develop those abilities, leaving you with a truly desirable skillset – after all, we believe you should always “Stay Hungry”!\n\nBy working closely with our DevOps teams, you will gain a strong understanding of the DevOps mindset, alongside hands-on experience using Amazon Web Services (AWS), Kubernetes and Docker. These skills will give you a great overview of the processes and methods required to work in a Continuous Integration/Continuous Delivery pipeline, with the potential to transition into a DevOps focused role if that is desirable.\n\nAs the team scales to support further platforms, services and projects coming from our pipeline, there will be a real opportunity for driven individuals to take on more senior positions within the department, including transitioning into Technical Lead or Lead Engineer roles.\n\nThere will be regular opportunities to work on large Greenfield projects with a genuinely global reach. We have a busy project pipeline so there will be plenty of possibilities for you to really make a mark on the direction of our platforms and services, whilst gaining exposure to a wide variety of areas of the business.\n\nWe’ll trust and support you to truly take ownership of your work, providing real autonomy on the projects you work on. We’ve got your back if necessary, but you’ll be entrusted to get stuck in and put your skills, and vision, to work. We truly believe that brilliant products are built by teams that work brilliantly together; but brilliant teams can only be built with brilliant people!\n \n\n#Salary and compensation\n No salary data published by company so we estimated salary based on similar jobs related to JavaScript, Node, Engineer, Backend, React, DevOps, Amazon, NoSQL and Senior jobs that are similar:\n\n $65,000 — $120,000/year\n
