Senior Software Engineer, Backend

About Centari

At Centari, we're transforming the world's contracts into actionable intelligence. Every firm has the same AI now. What separates them is institutional intelligence: how the firm has structured deals, priced risk, and navigated markets across every transaction it has closed. It's why a client picks one law firm over another, and why an LP backs one fund over the next. Today, this knowledge sits buried in closed deals and in the heads of the people who worked on them.

Centari brings it to the surface as structured data that AI can act on, empowering companies to generate new revenue and see opportunities no one else can.

The most demanding transactional practices in the world already build on Centari, including deal teams at Ropes & Gray, DLA Piper, Willkie, Fried Frank, and Wilson Sonsini. We proved it in law. Finance and the enterprise face the same problem at greater scale, and we're going after all of it.

We raised an oversubscribed Series A from investors including Sentinel Global, GTMfund, South Park Commons, Jack Altman, RiverPark Capital, and Recall Capital, and now we're building the team to match our ambition.
