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.


As Senior Backend Engineer you 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 to take the challenge they see fit.
