Design Engineer working on making LLMs useful for real people in a time-tracking product context.

Requirements

  • 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

Other

  • White collar businesses depend on fragile, time consuming data entry to plan, record, and execute work. Client services firms (~$10B TAM) are especially dependent on this broken process: lawyers, accountants, and consultants need to faithfully track their time in order to get paid. Lawyers spend an hour per day tracking their time, and fail to account for 20% of their work .
  • Ajax frees hardworking professionals to do their jobs by passively capturing, analyzing, and preparing the reports they owe their boss/client/whoever .
  • Our results speak for themselves:
  • 0% Customer Churn : we have never lost a firm (<10% annual is considered good)
  • 98% Pilot Conversion Rate : when we start pilots, we win them (>70% is considered good)
  • Customers say things like “I’m going to leave my husband for Ajax”
  • “I was so bad at time tracking that I was going to have to switch careers until I found you”
  • “This is somewhere between 5,000 and 10,000 better than what I was doing before”
  • “This is the easiest money I’ve ever spent”
  • 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
  • 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.
  • 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
  • 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
  • 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! 🎉
  • 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.
