Careers at Ajax

Come build with us.

Lawyers still track time manually in 6-minute chunks, losing $60 billion a year to missed entries. Ajax fixes that. Our AI writes entries for them, saving hours of admin and finding firms extra revenue.

Our ARR is doubling every 2 months, every firm who's tried us in the past 6 months has become a paying customer, and customers tell us they "have no idea how they lived without Ajax" ... and we're just just getting started.

Come build the back-office brain for law with us! If you like complex AI pipelines and a team that ships fast and celebrates wins together, let's talk.

Team Highlights

Siyou Pei

Product Engineer

Joined Ajax in July 2025

What is your favorite project since joining Ajax?

I actually have two:

(1) a next.js rewrite that made the app feel instantaneous: we rearchitected the UI and reduced interaction latency by 60+%, even with hundreds of entries and thousands of components on the page

(2) shipping a recent activities panel that updates automatically via postgres WAL replication: this real-time “domino’s pizza tracker” style panel assures even the most contemporaneous billers that Ajax is capturing their work in real time.

What is your engineering superpower?

Combining product design and engineering to solve end-to-end comprehensive problems :)

Anything else to add?

Nothing is greater than building meaningful stuff. We really care about the product and it feels so great to really make customers' lives easier.
