$170,000.00/yr - $205,000.00/yr Welcome to Crosby
We are a team of technologists and legal experts collaborating closely to reimagine corporate legal services from the ground up. We build proprietary technology and human-in-the-loop workflows to radically enhance the lawyer machine relationship. Our mission is to review complex documents faster than ever and with perfect quality. Crosby was founded by Ryan (Penn, Stanford Law, ex Cooley, former GC) and John (Penn M&T, ex Ramp, ex Google). We believe: A great legal system is the watermark of a great society. Legal work is art and science. We are discovering the frontier between the two—codifying what can be systematized, and amplifying human expertise where judgment matters most. The right way to deploy AI in law isn’t by selling software. It’s by selling outcomes — higher-quality legal work, delivered faster and more efficiently. In an in-person culture at our NYC office. The Role
As a Founding Frontend Engineer, you will own the user-facing experience of the Crosby platform. You will be responsible for building beautiful, intuitive, and highly functional interfaces that empower our legal professionals to work with unprecedented efficiency. You’ll collaborate directly with the founders, product, and our legal team to translate complex workflows into elegant user experiences. This is a chance to build our entire frontend from the ground up, establish our design system, and set the standard for quality and speed. What You’ll Do
Define the frontend: Architect and build the core frontend of the Crosby platform using modern frameworks like React, Vite, and TanStack. Design the user experience: Design and implement intuitive, high-performance user interfaces for complex, data-intensive legal workflows. Prototype and iterate fast: Work closely with product and our in-house legal team to rapidly prototype and iterate on user-facing features. Lay the foundation: Establish a maintainable frontend codebase, including our component library and design system. Collaborate deeply: Work with backend engineers to design and implement APIs that deliver a seamless user experience. Grow the team: Mentor and help recruit world-class engineers. What We’re Looking For
Experience: 4+ years of frontend engineering experience, with deep proficiency in TypeScript and modern frameworks (e.g., React, Vue, or Svelte). User Obsession: A strong sense of user empathy and attention to detail in delivering high-quality, polished products. Builder Mindset: Excited about creating and scaling systems from the ground up and making foundational technical decisions. Collaborative: Effective communicator who excels at working with cross-disciplinary teams, especially product, design, and backend. Ownership: Driven to take full responsibility for projects from ideation through execution and delivery. Curiosity: Passionate about learning and experimenting with new technologies to solve complex UI/UX challenges. Ideal Qualifications
Experience building interfaces for complex, AI-powered applications or agentic systems. Strong design sense and experience with modern design tools (e.g., Figma). Prior experience in a fast-paced, early-stage startup environment. Familiarity with Python and our backend stack. Why Work at Crosby
Foundational Impact: As a founding engineer, you will shape the user experience, culture, and technical direction of the entire company. Competitive salary and equity compensation. Comprehensive health, dental, and vision insurance. Unlimited PTO. In-person team in NYC with a collaborative, high-energy environment.
