Senior Full Stack Engineer

The Opportunity

We’re looking for a  Senior Full Stack Engineer  who will be one of the first technical hires at Monstro. This is a pivotal opportunity to lay the technical foundation of our platform, shape the overall core architecture, and become a founding member of our engineering team. You’ll work closely with our design, product, and executive teams to translate vision into scalable solutions, define technical requirements, and make critical decisions on Monstro’s technical stack, infrastructure, and security.

Your responsibilities will include leveraging our design prototypes and collaborating with subject matter experts to build and optimize both Monstro’s consumer web app and our institution platform.

The ideal candidate thrives in ambiguity, enjoys tackling complex challenges, and is passionate about building innovative technology that disrupts traditional financial systems. This role offers significant ownership, the ability to directly influence the product roadmap, and the chance to grow into a technical leadership position as Monstro scales.
