Who we are About Bridge We're creating an entirely new payments platform, built with stablecoins, to simplify global money movement. Bridge enables faster, cheaper payments and borderless access to dollars via stablecoins. Through our APIs, businesses can send and receive funds across borders faster and cheaper vs. SWIFT and other fiat-only rails. Our virtual accounts enable international consumers and businesses to easily access, store, and spend US dollars. Our payouts infrastructure enables platforms to disburse USD to anyone globally. We believe many trillions of dollars will move and settle through stablecoin payment rails. Bridge is pulling this future forward. We have a small team of people who have previously built financial infrastructure at some of the world's leading companies (Coinbase, Stripe, Square, Brex, Upstart, DoorDash, Airbnb), and each and every one of them chose Bridge because they fundamentally believe that stablecoins will be a critical piece of financial infrastructure that allows for the improvement of global money movement. About the Role As an early member of the Bridge engineering team, you'll have the autonomy to work on projects that are truly global in scale and aim to give customers access to products they've never had access to. Many of the use cases that we work on today didn't exist several months ago, and that's because our team is dedicated to constant improvement for our partners and end users. Our engineers have outsized ownership over projects, so if you're looking for increased autonomy working on a completely greenfield opportunity, Bridge is the place for you. Responsibilities • Ship software to build out our suite of API products. We're an engineering and API-first company, and you'll learn first-hand and contribute towards building highly reliable, performant, and business-critical infrastructure serving thousands of developers across the globe. • Take sole ownership of projects, oftentimes without the support of Product Management, and liaise both internally with teams like Legal and Compliance and externally with our partners and developers. • Look for constant improvements to our product offerings with the explicit goal of improving the experience for our partners and end users. • Make effective tradeoffs that consider business priorities, user experience, and a sustainable technical foundation. • Improve engineering standards, tooling, and processes for the team and our broader org. Who you are We're looking for someone who meets the minimum requirements to be considered for the role. If you meet these requirements, you are encouraged to apply. The preferred qualifications are a bonus, not a requirement. Minimum Requirements • We're open to hiring engineers at various levels of seniority (SWE through Senior Staff), but at a minimum we're looking for somebody with 5+ years of experience. • Experience building backend systems with SQL databases. Experience with frameworks such as Rails, Django, Express, or equivalent is a bonus. • An enlarged sense of ownership and the ability to lead and influence the design and direction of our products • An ability to thrive in a fast-paced environment • A growth mindset, constant curiosity, and fearlessness to dive into the unknown • An ability to write maintainable, well-tested, modular code, but also be pragmatic about moving fast • Excellent written and verbal communication skills, including the ability to write clear technical documentation Preferred Qualifications • Past experience working on crypto or financial products a plus, and while not required, we do look for people who are very passionate about building in this space • Experience with building API products a plus, but not required • Experience working with blockchain or distributed systems a big plus
