Front-End Leaning Full-Stack Engineer
About The Position
Moritz Legal is building an AI-native law firm, designed from the ground up around AI. They started by building AI software for lawyers but realized that even better tools couldn't overcome the misaligned incentives of the billable-hour model. So they became the law firm themselves, using the tools they build in-house to deliver faster, better, and more affordable legal services to fast-growing tech companies. At the core is Moritz, their SaaS platform for legal case management that powers swift document reviews, intelligent drafting, and effortless legal research. They are a small, tight-knit founding team spread across San Francisco, London, and Oslo, backed by $9M in funding. The culture is fast-paced, ownership-driven, and deeply collaborative. This role is for a front-end leaning full-stack engineer to ship features end-to-end across their Next.js and tRPC stack. This is a greenfield product with no legacy migrations or tech debt. The engineer will work directly alongside the founders and the design engineer in London to shape product architecture from day one. A central deliverable of this role is making the app beautiful and fully responsive across mobile, tablet, and desktop.
Requirements
- 3+ years of full-stack experience building B2B SaaS products, shipping features end-to-end
- Proficiency in React, TypeScript, and the Next.js App Router
- Experience with tRPC (or similar API layers) and PostgreSQL
- Strong responsive/mobile-first design skills with Tailwind CSS
- Experience with shadcn/ui, Figma, or design-system collaboration
- Testing experience with Vitest, Playwright, or equivalents
- Ability to work autonomously in a fast-paced, early-stage environment without detailed specs
- A true full-stack, growth mindset — not narrowly specialized in only frontend or only backend

- Prior role at a legal tech company (e.g., Harvey, Spellbook, Norm AI)
- Experience at an early-stage startup (seed or Series A)
Responsibilities
