Apr 10, 2023 - CloudWalk is hiring a remote Data Scientist. 📍Location: Brazil.
If you have fallen and risen, if you have broken and fixed, if you have dreamt and built, then you have grit. Then we speak the same language. Welcome to the Wolfpack.
We are one of the fastest growing fintechs on the planet. We kick ass. A unicorn, with millions of happy customers, a hardcore team, and hundreds of millions in funding and revenue. But not your typical startup.
We build and learn, fast, and we want the hackers, the artists, the crafters - join the Wolfpack!
“There is an art to flying, or rather a knack. The knack lies in learning how to throw yourself at the ground and miss. ... Clearly, it is this second part, the missing, that presents the difficulties.”
- CloudWalk is an AI first company building its own technology to bring justice to the broken payment system in Brazil. We are building what one would call a “self-driving bank”.
- Some people say a company is a unicorn when it reaches a valuation of over 1 billion dollars. We are one of those companies. But we are also a much cooler type of unicorn: a freaking amazing beast that is incredibly rare, cool as hell and damn hard to catch.
The R&D team:
- We love living in a time when there’s access to an immense corpus of shared knowledge and incredible statistical and computational tools to extract meaningful information from the data.
- We love thinking in high dimensions.
- We like to explore before we exploit.
- We sprinkle sci-fi references in everything we do.
What the job entails:
- You'll have access to tons of data, but you'll also be cursed with tons of noise. Most humans are good and amazing, so every bad behavior is hidden behind a swarm of good behavior. To identify the baddies, you will need to look for clues as to what is going on, to look for patterns, to ask intelligent questions and look for answers, to deal with uncertainty, to find the story behind the data, to turn the data into information. You'll need to be a detective.
- You will create new ML models and techniques and expand on the ones we have in production.
- You will have the chance to experiment. Do you think that the hot new model from a newly published paper can be applied to some of our data? Let's try it! Do you think the atmospheric pressure, the migration pattern of birds or the number of capybaras living on the border of the Pinheiros river are good predictors of credit card fraud? Let's investigate the data! Do you think there's a different perspective to look at a certain problem that could solve it better or complement our current approach? Let's put that to the test!
- You might have taken a bunch of courses and learned all about NNs, CNNs, RNNs, SVMs, CARTs, RFs, LDA, QDA, XGB, BERT, SD, GPT, and all that nice stuff. Those are all techniques to learn a mapping from X to Y. Here, you will also have to think long and hard about what X you'll be mapping to what Y.
- If you never allow yourself to fail, you will never allow yourself to take risks. The next big breakthrough will not come from someone who's playing it safe. Here, you'll be expected to experiment and you'll be allowed to fail, as long as you learn something. Over 99% of all species that ever existed on Earth are now extinct. But the remaining 1% would not have succeeded without them.
- Not going to lie. Sometimes you will have to do things you might not particularly enjoy. There will be times when we'll be at war, when we'll be together in the trenches, fighting the enemy, shoulder to shoulder, doing whatever needs to be done.
- As a member of a fully remote and distributed team, you are expected to complete tasks autonomously, being highly collaborative and self-driven.
- You must understand what machine learning is and what it’s not, and be able to identify and implement potential applications.
- You must be able to go through large amounts of data and identify useful patterns and relationships.
- You must be comfortable with programming. You’ll be doing most of your work in Python and SQL, but we believe that coding is mostly about problem solving and that programming skills are highly transferable between languages.
- You must be in your element reading and discussing research papers and coming up with potential applications to our problems.
- You must be able to communicate and debate in English. We’re proud to be a global team with members spread all over the world. Portuguese is not required.
Recruiting process outline:
- Our selection method is simple but hard. If you pass, you are definitely smart.
- 1) Online technical assessment
- If you are not willing to do an online quiz, do not apply.
Diversity and Inclusion:
- We believe in social inclusion, respect and appreciation of all people.
- We promote a welcoming work environment, where each CloudWalker can be authentic, regardless of gender, ethnicity, race, religion, sexuality, mobility, disability or education.
We are not expecting candidates to have expertise across all of these areas. We will gladly help you bridge the gaps.
