At this moment in time everyone at Vizzuality is working from home/remotely. If this type of flexibility is something you are looking for you will be very welcome to join us. Regardless of your preferred location, and so we can make sure to keep our operations and the team running smoothly, we would be particularly interested to hear from you if you are willing to overlap some/all of your day to day working hours with our teams in Spain and Portugal.



Would you like to be part of Vizzuality’s story?


Are you motivated by the desire to help build a sustainable planet for all life on Earth? Are you looking for a new opportunity?


Vizzuality’s purpose is to reach a fair and sustainable planet by creating tools that radically empower people to make positive changes now. We are a world-leading technology agency based in Madrid, Cambridge, and Porto. We design and develop data-driven tools and applications for international organisations who focus on Climate Change, Biodiversity and Inequality.


Solving such large and complex problems will bring you into contact with new technology and some of the world’s most interesting organisations and academics in machine learning, remote sensing, and planetary data. You’ll be working on projects like these:

  • We Care:
    • For ourselves, our colleagues, the organisation.
    • We know what we do is important and we have a strong sense of responsibility for the work we do.
  • We Grow:
    • As we are always embarking on new projects and challenges, a continuous learning mindset and a “Can Do” attitude is a must
    • We are conscientious, we focus on learning and achieving our goals
    • We empower people to make decisions, to plot their own paths with help from all around them
  • We have fun:
    • But we also know that you need to balance seriousness with fun.
    • If you can make people smile you will be off to a great start!

A day in the life of a Software End Engineer at Vizzuality


We’re looking for someone to work alongside a world class and super talented team of engineers, designers, researchers, scientists and project managers. Someone who is passionate about using their creativity and technical skills to make a difference in people’s lives, the environment and to help make the world a better place.


  • You will be designing and developing cross-functional, multi-platform application systems to ingest, process, analyze and serve large amounts of data in the cloud, often in real time, and ensuring their craftsmanship, availability, resilience, and scalability.
  • Working hands-on across our stack is one of the things Engineers at Vizzuality do the most. You will be working on NodeJS, Rails and/or the Python stack and will also be experimenting with new technologies. If you don't know about a specific technology or get stuck on a tricky problem, you will always have someone around to help you learn and move forward.
  • You will have the opportunity of taking ownership of projects and participating in meetings with clients at different stages of the development process in order to help define requirements, propose solutions and alternatives.
  • A lot of your time will be spent 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 be communicating with users, colleagues, leading scientists and decision makers to collect requirements, describe features and technical designs, and define product strategy.
  • Last but not least, our engineers ensure software quality, robustness, and compliance with standards by reviewing code, documenting, and creating automated tests.

These are some of the things you will be achieving in your first year at Vizzuality


  • In your first month:
    • You’ll pair with your peers in the backend team so you get used to the way of doing things 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 rest of the functional teams (science, design, front-end, business development) and development teams.
    • At the end of your first month, you’ll be joining a longer project.
  • 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 be leading the back end work in communication with your project team and support from the back end functional group.
    • You’ll also develop your skills around data-rich application engineering, cloud computing and data processing.
    • Finally, you’ll participate in the definition of architectures and functional features for new project phases or new projects.
  • By the end of the first year:
    • You’ll already have written several innovative features for ground-breaking projects with large real-world impact (we absolutely mean this!).
    • You’ll be leading the software engineering process in your own projects.
