Check our <a href="https://playbook.vizzuality.com/">Playbook</a>.  A day in the life of a Back-End Engineer at Vizzuality  We're looking for an engineer 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. DevOps as a Culture, Not a Team. At Vizzuality, we don't have a separate DevOps team. DevOps is part of how every engineer works. Our back-end engineers own the full lifecycle of their services: from writing code to deploying, monitoring, and operating it in production. You'll be expected to manage cloud infrastructure, write Infrastructure as Code, configure CI/CD pipelines, and troubleshoot production issues alongside your development work. If you thrive on owning what you ship end to end, you'll feel right at home. <ul><li>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.</li><li>Working hands-on across our stack is one of the primary tasks engineers perform at Vizzuality. </li><li>Our core stacks are NodeJS/TypeScript (with NestJS/FastAPI (when developing in Python) as the main frameworks, depending on the project). You will work on different 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.</li><li>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.</li><li>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.</li><li>You will also communicate with users, colleagues, leading scientists, and decision-makers to collect requirements, describe features and technical designs, and define product strategy.</li><li>You will be responsible for infrastructure: building and maintaining CI/CD pipelines and ensuring the platform is resilient, observable, and maintainable.</li><li>Lastly, as an Engineer at Vizzuality, you will ensure software quality, robustness, and compliance with standards by reviewing code, documenting, and creating automated tests.</li></ul> These are some of the things you will do and achieve in your first year at Vizzuality. In your first month:<ul><li>You’ll pair with your peers on the backend team so you get used to the way things are done at Vizzuality.</li><li>You’ll read documentation, write new features, and participate in team meetings (weekly, with the possibility of daily stand-ups on some projects). </li><li>You’ll get to know people from the other functional teams (science, design, front-end, business development) and development teams. </li><li>You'll join a more extended project at the end of your first month.</li></ul>During the following months:<ul><li>You'll develop ownership of the project you've been assigned to. </li><li>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. </li><li>You'll also have opportunities to develop your skills in data-rich application engineering, cloud computing, and data processing. </li><li>Finally, you'll participate in defining the architectures and functional features for new project phases or projects.</li></ul>By the end of the first year:<ul><li>You will have written several innovative features for ground-breaking projects with significant real-world impact (we mean this!).</li><li>You'll take ownership of substantive features within larger backend projects.</li></ul> Skills and experiences we are looking for in a candidate(*) Even if you think you don't tick all the boxes below, we'd still love to hear from you.
