Founding Frontend Engineer

We're 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.

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.

• Strong design sense and experience working with modern design tools (ex: Figma)

• Prior experience working in a fast paced, early stage startup environment.
