2) A day in the life of a Back-End Engineer at Vizzuality
We're looking for a developer to join our talented team. You'll use your creativity and technical skills to make a difference.
A Junior Developer at Vizzuality works on simple tasks and grows their skills. They rely on team mentoring to improve.
Our Mid Developers create new features from scratch. They work to integrate these features into the codebase. They understand the software development life-cycle well.
They can work with little supervision. They know what businesses need and offer ways to improve. They turn these ideas into technical solutions and implement them on their own.
They also know how to work well with others. They can guide junior team members.
- 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.
