Description For Seed Stage, Fintech, Sr. Frontend/Full Stack Engineer

StackedSP Inc is an exciting early-stage FinTech startup founded in 2023, backed by prestigious investors including Accel and Neo, with approximately $7M in funding. We're building a cutting-edge trading platform capable of handling $100M+ in transactions, and we're looking for a Senior Frontend/Full Stack Engineer to join our founding team.

As a Founding Engineer, you'll have the unique opportunity to shape our technical foundation from the ground up. You'll be working with modern technologies like React, Next.js, and TypeScript to build robust, scalable systems that power our financial trading platform. This role offers a perfect blend of frontend expertise and full-stack capabilities, where you'll be responsible for architecting frontend foundations while also contributing to end-to-end system design.

We're a small team (less than 10 people) with founders from prestigious backgrounds including Google, Rubrik, and Morgan Stanley. We offer a truly remote-first environment, though we maintain connection through quarterly trips to Austin and twice-yearly off-sites for team bonding and strategy sessions. The compensation package includes a competitive salary range of $140,000 - $200,000, plus meaningful equity in our venture-backed startup.

This role is perfect for someone who thrives in early-stage environments, has a passion for FinTech and marketplaces, and wants to make a significant impact. You'll have the opportunity to work directly with founders, shape product strategy, and build complex systems from scratch. We're looking for engineers who are not just technically excellent, but who also embrace the challenges and opportunities that come with building a financial platform from the ground up.
