Some news: I'm starting at [Sigma Squared](https://www.sigmasquared.io/?ref=petercai.com) as VP of Engineering. I'm especially excited to help the company enter a new vertical in law enforcement. Law enforcement agencies everywhere have been inundated with nonsense statistics that confuse disparity with bias. We're going to fix that.

The 7+ years I spent at Privy were pretty intense, and I definitely underestimated how much I needed this long break (achievement unlocked: leaving without a Tom Brady-esque farewell). Jackie and I have been taking time to care for family (we got hit hard by covid), to rest, go to allll the weddings, and to reflect deeply. With things stabilizing, it feels like a natural transition point to join a mission-driven company I can give 100% to.

The team is [hiring in engineering, data science, product, sales, and success](https://www.sigmasquared.io/careers?ref=petercai.com) in Cambridge - but know that this won't be a leisurely walk in the park. Let's talk / reconnect if you're ready to make this the hardest, most impactful work of your career.
