Our mission
Lawyers spend up to an hour per day tracking the work they’ve done, and fail to account for up to 20% of their work. Our goal is twofold:
Obviate the time tracking problem: track so accurately that interns could review the bills
Give law firms the management data they need to offer high-quality legal services at scale
Right now, law firms can’t undermine their pricing power by buying tech that speeds up the delivery of legal services. That sucks, and the data we collect lets firms figure out intelligent pricing strategies for the 21st century.
Metrics we’re proud of We’re solving the worst problem 1.5 million attorneys in the US face. Our metrics are exceptional:
14 customers have invested in Ajax with their own money
<1>: we build long term partnerships with our customers (<10>
96% Pilot Conversion Rate: when we start pilots, we win them (>70% is considered good)
140% Net Dollar Retention: after firms convert with Ajax, they share it with more and more employees (>120% is considered good)
Working at Ajax
How we work, in practice
Here’s a real sprint we had in November:
During a pilot with an important firm, the GTM team noticed that activation was low
We pulled some data from Posthog and Metabase and came up with a hypothesis: these users were the fastest billers we’ve ever seen, and Ajax’s entries weren’t ready for them in time
Nat restructured our React FE to show a Domino’s pizza style “entry in progress” tracker, assuring nervous billers that their work was indeed captured
Alex issued a native app update for our Flutter app that captured data more quickly when users task switch
Roger optimized some gnarly python async code to bring our p99 entry latency from ~180s to ~120s.
We won the pilot!
Who you are
Ownership: a wise man* once said the difference between senior engineers and junior engineers is that senior engineers own the feature into production and beyond
Empathy: to build features end to end, you must be able to sit in our customers' shoes. Our company makes bs work go away for lawyers that work really hard; that needs to speak to you.
Resourceful: you're scrappy: you prefer figuring bugs out yourself to putting your hands up.

What you’ll do
Prototype, test, and deploy new features like...
What abstractions should our firm intelligence layer build atop the raw data ingestion?
How can we go from processing 2TB (today) to 50TB (soon!) per day?
Architect our existing 1TB/day pipeline to scale to 100TB
Meaningfully contribute to team composition: every eng interviews every candidate
You’ll excel here if
Your reward function is customer happiness (stolen verbatim from our 2nd engineer).
You want ownership - that means shipping your ideas and owning the results.
You like adventure. We’re solving an unsolved problem, so we need to be brave and rigorous in our exploration. The optimal number of unsuccessful experiments is higher than 0.
I like working here because we win a lot, we’re solving previously-intractable technical challenges, and at least once a week a customer tells me that our product is saving their life. If that sounds fun to you, send me an email.
FAQs
How far along are we?
Can I work remotely?
We usually work 5 days/week in-person in FiDi, NYC. We’re flexible, though, and we get that people are adults - Tyler worked from home when he had some family staying over, and Nat took a Wednesday off recently because she had take delivery of a rare fish (don't ask).
Compensation: $210-$270 base + .25%-.75% equity.
The range is wide because we’re open to a range of seniorities.
Offers may extend above but will not dip below the stated range.
We also offer unlimited PTO, paid lunch/dinner on Fridays, and health/dental/vision.
