Full Job Description
The Role
Who you are
  • An engineer with a design portfolio, or a designer with a github
  • With >2 years of experience building and iterating on live products
  • Who wants to work to make these crazy LLMs useful for real people
What you'll do
  • Talk to customers, figure what problems they have, and build the solutions
  • Figure out the right abstractions for a firm intelligence platform atop our timetracking
  • 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 exploration. The optimal number of unsuccessful experiments is higher than 0.


Working at Ajax
How we work, in practice

Here's a real sprint we had in November:
  1. During a pilot with an important firm, the GTM team noticed that activation was low
  2. 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
  3. Siyou restructured our React FE to show a Domino's pizza style "entry in progress" tracker, assuring nervous billers that their work was indeed captured
  4. Alex issued a native app update for our Flutter app that captured data more quickly when users task switch
  5. Roger optimized some gnarly python async code to bring our p99 entry latency from ~180s to ~120s.
  6. We won the pilot!


FAQ
  • How far along are we?
    • Our team is 10 people (5 engineers, 5 Go To Market)
    • We've raised >$10mm in venture funding from excellent VCs
    • We doubled revenue between March and July 2025, then again by November, then again by January
  • Can I work remotely?
    • We usually work in-person in Tribeca, NYC.
    • One of my favorite books is The Idea Factory - Bell Labs thought being in-person was essential to their research. I'm not going to outsmart anyone at Bell Labs, but it is 2026, so we have some flexibility: in the last week, Tyler (activation associate) worked from home b/c his siblings were in town, and Roger worked from home b/c he had a cough.
  • Compensation: $180-$240 base + .5%-1% 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.
