About Us

We’re on a mission to make taxes effortless for everyone. Backed by top-tier investors, we’re building a platform that empowers fintechs, banks, and tax advisors to launch powerful tax features for their end users with just a few lines of code.

The Role

To drive this vision, we’re seeking an experienced Full-Stack Software Engineer (TypeScript) who has a passion for building products from the ground up, owning them end to end, across the stack.

• Culture Building: Play a key role in fostering a high-performing, collaborative engineering culture as we scale the team.

Requirements

Experience We’re Looking For

Strong technical background with 5+ years of full-time engineering experience, preferably across the following tech stack:

• 😻 Frontend Development: Strong proficiency in React, Next.js, and TypeScript. Familiarity with state management libraries (Redux, Zustand) and modern styling (TailwindCSS, Styled Components).
• 🚀 Backend Development: Solid experience with Nest.js (or Express.js) and designing scalable RESTful or GraphQL APIs. Strong knowledge of authentication (JWT, OAuth2) and event-driven architectures (Kafka, WebSockets).
• 🏦 Database Management: Expertise in PostgreSQL, schema design, query optimization, and ORMs like Prisma.

While these would be ideal, please also apply if you’re not covering all aspects - we’re trusting you to pick up what’s needed quickly!
