Full-Stack Software Engineer (TypeScript)

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

We’re headquartered in Berlin and offer a remote-friendly environment.

The Role

We’re looking for an experienced Full-Stack Software Engineer (TypeScript) who loves building products from the ground up and owning them end-to-end across the stack.

You’ll join our core tech team and help lay the foundation of our platform in a low-hierarchy, high-impact environment.

The Opportunity

• Shape the architecture: Influence key technical and product decisions from the earliest stages.
• Build critical infrastructure: Develop the backbone of a tax platform designed to simplify taxes across Europe.
• Empower partners: Enable fintechs to embed and create their own tax tools through seamless integrations.

Your Responsibilities

• Hands-on ownership: Design, implement, and scale the platform foundation from scratch.
• Architect & execute: Make key architectural decisions and build robust, reliable, and maintainable systems.
• Feature delivery: Ship high-quality features quickly without compromising performance or reliability.
• Culture building: Help shape a high-performing, collaborative engineering culture as the team grows.

Experience We’re Looking For

Backend Development

• Strong experience with Nest.js or Express.js.
• Designing scalable RESTful or GraphQL APIs.
• Deep understanding of authentication (JWT, OAuth2).
• Experience with event-driven architectures (Kafka, WebSockets).

Frontend Development

• Strong proficiency in React, Next.js, and TypeScript.
• Experience with state management (Redux, Zustand).
• Familiarity with modern styling solutions (TailwindCSS, Styled Components).

Database Management

• Expertise in PostgreSQL, schema design, and query optimization.
• Experience with ORMs such as Prisma.

Cloud Infrastructure (Nice to Have)

• Google Cloud Platform (Cloud Run, Cloud Functions).
• CI/CD pipelines (GitHub Actions).
• Docker and Kubernetes.

Even if you don’t meet every requirement, we encourage you to apply — we value strong fundamentals and the ability to learn quickly.

Who We’re Looking For

• Autonomous builder: You take full ownership and manage projects from start to finish.
• Maker mindset: You prefer focused building and shipping over endless meetings.
• High standards: You care deeply about clean, maintainable, high-quality code.
• Team player: You thrive in a high-performing environment with ambitious peers.

Bonus Points

• Experience with Go or Kotlin.
• Strong understanding of microservice architectures and high-load systems.
• Background in fintech, payroll, tax, or regulated industries.
• Experience building embedded or white-label software products.

What We Offer

• Impact from day one: Your code will power tax tools used by financial institutions across Europe.
• High-performance team: Work alongside ambitious, talented engineers.
• Hybrid/remote flexibility: Berlin office hub with remote options.
• Fast career growth: Help build the engineering organization you’ve always wanted to join.
• Creative freedom: Bring your ideas to life with real ownership.
