Legal Engineer

FluxCap | New York City or Washington, DC | Hybrid | Full-time

Help turn legal expertise into software other lawyers can use.

Strong cases should get their day in court. FluxCap helps lawyers connect the law, evidence, and strategy of a case so they can take on bigger opponents and win on the merits, regardless of the size of their team. We’re starting with antitrust.

Founded by Jonathan Kanter and Doha Mekki, former leaders of the Justice Department’s Antitrust Division, FluxCap brings together former DOJ lawyers and engineers from Palantir and Meta. We’re backed by Y Combinator, Bloomberg Beta, and other investors.

You’ll work with litigators and software engineers to shape how FluxCap helps lawyers build a case. You’ll bring legal judgment to product development: identifying what a claim requires, testing whether the evidence supports an argument, and explaining where the software’s analysis falls short.

You’ll also work directly with lawyers using FluxCap. You’ll learn how they approach their cases, help them use the product, and bring what you learn back to the team.

This role combines substantive legal analysis with building and improving software. You don’t need to write code, but you should enjoy learning new tools and working through problems with engineers.
