A day in the life of a Back-End Engineer at Vizzuality  We're looking for a developer who will work with a world-class, super-talented team of engineers, designers, scientists, and project managers. Someone passionate about using their creativity and technical skills to make a difference in people's lives, the environment, and the world. You will design and develop cross-functional, multi-platform application systems to ingest, process, analyze, and serve large amounts of data in the cloud, often in real-time, and ensure their craftsmanship, availability, resilience, and scalability. Working hands-on across our stack is one of the primary tasks engineers perform at Vizzuality.  Our core stacks are NodeJS/TypeScript (with Express/Koa/NestJS as the main frameworks, depending on the project). You will work on NodeJS/TypeScript projects and experiment with new technologies. If you hit a snag or need to learn a new skill, our supportive team is always there to lend a hand and help you conquer any challenge. You will take the lead and meet with clients at different stages of the development process to help define requirements and propose solutions and alternatives. You will spend a significant amount of your time liaising with data scientists, front-end engineers, project managers, and designers to find novel and creative technical solutions that solve specific client/project needs and integrate disparate technologies such as remote sensing, machine learning, image processing or statistical computing into public APIs. You will also communicate with users, colleagues, leading scientists, and decision-makers to collect requirements, describe features and technical designs, and define product strategy. Lastly, as an Engineer at Vizzuality, you will ensure software quality, robustness, and compliance with standards by reviewing code, documenting, and creating automated tests. 3. These are some of the things you will do and achieve in your first year at Vizzuality. In your first month: You’ll pair with your peers on the backend team so you get used to the way things are done at Vizzuality. You’ll read documentation, write new features, and participate in team meetings (weekly, with the possibility of daily stand-ups on some projects).  You’ll get to know people from the other functional teams (science, design, front-end, business development) and development teams.  You'll join a more extended project at the end of your first month. During the following months: You'll develop ownership of the project you've been assigned to.  You'll write features, documentation, tests, and fixes. You will join the back-end work within your project team and with support from the back-end functional group.  You'll also have opportunities to develop your skills in data-rich application engineering, cloud computing, and data processing.  Finally, you'll participate in defining the architectures and functional features for new project phases or projects. By the end of the first year: You will have written several innovative features for ground-breaking projects with significant real-world impact (we mean this). You'll take ownership of substantive features within larger backend projects. 4.
