TL;DR — Build the Future of Tax Technology with Us


We're revolutionizing tax technology by building a platform that enables fintechs, banks and tax advisories to offer their own tax solutions with ease. Backed by leading investors, we're assembling a small, high-performance team and are looking for a Fullstack Engineer. If you are an engineering rockstar that thrives on innovation and dreams of disrupting a traditional industry with technology, then join us to revolutionize the way everyone does their taxes!


About Us


Our founding team has 10+ years of complimentary experience in the domain (Tax Advisory / CPA) coupled with a track record in launching and scaling startups. We are backed by leading investors and strategic angels from the tax and fintech space. Now, as we grow with early customers, we’re building a small, high-performance tech team where autonomy and ownership are at the core of everything we do.


The Opportunity


You have the chance to join us as an early member of our tech team, actively shaping and building our technology base from the ground up.


You'll build a platform that transforms tax technology, enabling tax advisors and fintechs to offer and create their own tax tools—without needing extensive software development expertise [and potentially by utilizing LLMs to digitize tax law ;) ].


Tasks

Your Responsibilities



  • Take end-to-end ownership building critical parts of our emerging technology from the ground up

  • Collaborate closely with the CTO to execute the product roadmap

  • Delivering new features, and highest quality code at god-speed, ensuring timely and high-quality releases.

  • Contribute to our strong, high-performance and collaborative engineering culture as the team grows.


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.

  • 🌥️ Cloud Infrastructure (Nice to Have): Experience with Google Cloud Platform (Cloud Run, Functions), CI/CD pipelines (GitHub Actions), Docker, and Kubernetes.


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!


Who We're Looking For


This role is ideal for a seasoned engineer eager to join a well-funded company at its early stages where most of the product is still to be built. You’ll be a strong match if:



  • You excel in autonomy, taking ownership of the details, and have a strong ability and drive to manage your own projects and work from start to finish

  • You prefer focused building and coding time over meetings and love being productive, and shipping high-quality code

  • You’re excited to be part of a high-performing team, surrounded by talented peers who will challenge you to grow and are ready to tackle the ambitious road ahead


Bonus points



  • 🚀 Knowledge of one or more programming languages such as Go or Kotlin

  • 🎛️ Good understanding or experience with microservice architecture, as well as experience with high-loaded systems

  • 💸 Experience in fintech projects or startups.

  • 💰 Experience in building products in regulated industries like payroll, fintech, or tax or had projects where you build a tax solution

  • 📩 Experience in building embedded/white-label software products


We value hustle and heart. If you have the technical chops and an entrepreneurial spirit, we want to hear from you, even if your experience isn't a perfect match.


Let's disrupt the tax industry together.
