(Senior) Software Engineer

Few people get to build a bank from scratch. Even fewer get to build one at a moment when banking itself is being reinvented. The Dollar is the best product in the history of the world - there is infinite global demand. But International Fintechs and non-US banks are left with two unsatisfying options to access it: Either they build on legacy clearing banks that are slow and unreliable, or they interface with middleware providers that don’t move and hold the dollars directly, but themselves rely on underlying legacy banks. Augustus collapses this stack by combining two things: A real, national bank charter (in organization), and Marble, our proprietary core banking system, built around intelligence, made of code. We are a group of operators, unicorn early employees, ex-founders and people who walked away from degrees because they believe this is an industry and career defining opportunity. We are backed with more than $200M from Peter Thiel's Valar Ventures, Tiger Global, Hummingbird, QED, Creandum, and the founders of Nubank, Ramp, Deel, Circle, Fluidstack, Fuse, and n8n. We are regulated in Europe and live with Euro and Stablecoin clearing today. Now, we are building the US team from the ground up, while continuing to grow rapidly in Europe. The Role You're a super IC in a small, elite engineering team. You work on core banking systems and own projects end to end. You take on big projects, drive them yourself, and deliver. You work with engineering, product, and clients. You turn complex financial problems into clean code. You're trusted with the big calls from day 1; system design, technical tradeoffs, what we build and what we don't. The team is small on purpose, that means you have a lot of ownership, you move fast, and you make decisions that actually matter. You're part of the product engineering team building the Programmable Bank - a bank for the new age of money movement, built around Digital Assets and AI. Your team builds the banking core across bare metal central bank infrastructure and blockchain infrastructure. We're building a Swiss clock: your job is precision engineering, translating a complex system into simple, clean code that runs reliably at scale. Your First Six Months Understand the codebase and increase your ownership rapidly. Months 1-2: You ramp up fast. Understand the codebase, the domain, the product and ship meaningful code in your first weeks. Pick up a major project as an IC and start driving it. You're pairing with the team but operating independently early. Months 3-4: You've shipped your first big project end to end. You know the domain well enough to push back on product decisions when something doesn't make sense. You're starting to influence technical direction - how we model data, how we handle edge cases, where we take shortcuts and where we don't. Months 5-6: You're one of the people the team relies on for the hardest problems. You scope and drive projects autonomously. You have strong opinions on how the
