Uphold Braga, Portugal


About Uphold

At Uphold, our mission is to establish a trusted, consumer-focused platform that creates easy and fair access to financial services worldwide. Since inception, we have fought to provide a fairer, easier and more affordable system. We favor speed, simplicity and ease of use over complexity. We put security and transparency first. Our commitment to transparency sets a new standard for the industry. Unlike banks, we are fully reserved, and transparent: we hold assets to match our obligations and publish both in real time.


The Junior Frontend Engineer will be joining a team of makers that are passionate about technology with a great sense of responsibility. Every day we focus on building and improving our systems with scalability in mind based on these three core principles: maintainability, performance, and security. We stand by the idea that source code is a liability, not an asset, so we do our best to keep things simple while making sure they can achieve the desired outcome. We are continuously challenging ourselves, both individually and as a team, to never stop learning. We work collaboratively with a collective code ownership mindset to design and implement complex technical projects, balancing speed with quality, learning from our past mistakes and allowing everyone time to take the challenge they see fit.
