# Senior Product Designer at Ajax

- **Company:** Ajax
- **Location:** New York, NY
- **Employment:** full-time
- **Work type:** onsite
- **Posted:** 2026-08-06
- **Last confirmed live:** 2026-09-09
- **Apply:** https://jobs.ashbyhq.com/ajax/b6aa7a93-8190-4bdf-aa0c-e76bd6e0b2b4

## Job description

## WHAT WE’RE BUILDING

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:

- 99% Customer Retention: firms that buy us stay with us (>90% annual is considered good) https://chatgpt.com/share/694c073e-9004-8001-9eeb-c0bc41bab23b
- 96% Pilot Conversion Rate: when we start pilots, we win them (>70% is considered good) https://chatgpt.com/share/694c0787-79b4-8001-8cb5-3074bd6a5f1c
- Customers say things like (all real quotes):
- “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”

Designing this well is unusually hard. Our system is fundamentally cooperative; the product must fold into our users’ daily habits while fading into the background and - eventually - eliminating the task of timekeeping altogether.

## THE ROLE

## WHO YOU ARE

- A designer with a portfolio of shipped products…
- Who can operate independently as a designer and collaboratively with engineers…
- And can turn dense, information-heavy workflows into delightful, fast experiences

## WHAT YOU’LL DO

- Talk with lawyers, firm administrators, engineers, and our go to market team; watch people actually work and then actually write time entries; identify problems worth solving
- Define core trust loops for our customers: what is captured, how is it generated, and
- Figure out the right abstractions for a firm intelligence platform atop our timetracking
- Meaningfully contribute to team composition by interviewing designers and engineers

## YOU’LL EXCEL HERE IF

- Your reward function is customer happiness (stolen verbatim from our 2nd engineer).
- You want ownership - that means work is done when it's live and our users are delighted,, not when it’s engineer-ready in Figma.
- 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. We 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! 🎉

## FAQS

- How far along are we?
- We have 180 paying law firms and thousands of users

- We’ve raised $10mm in venture funding from excellent https://www.fika.vc/team VCs https://mxv.vc/
- Can I work remotely?
- We usually work 5 days/week in-person in Tribeca, 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.

## Core Business

## Products & Services
- **Ajax AI Timekeeper** (SaaS): The core product. Continuously monitors a lawyer’s work across Word, PDF, email, browser, VoIP calls, calendar, Zoom/Teams, and other tools.

- **Email Filing** (Feature): Automatically matches emails to the correct matter and files them in the practice management system without manual drag‑and‑drop.

- **Personalised AI**: The system learns from each user’s edits, adapting to their voice, billing preferences, and client requirements over time.
- **Security & Privacy**: SOC 2 certified, end‑to‑end encryption, configurable rolling data deletion, and a strict policy of never training AI models on customer data. Raw activity data is automatically purged.
- **High adoption rate**: The product is designed to fit naturally into a lawyer’s existing workflow (works in the background, one‑click sync), resulting in a 95% pilot‑to‑subscription rate.

## Strategic Focus
Ajax’s stated ambition is to become “the OS for the modern law firm” — [joinajax.com/careers](https://joinajax.com/careers). Near‑term priorities include:
- Expanding timekeeping automation to more billing systems and geographies.
- Building additional modules for client reporting, profitability management, and business development using aggregated Ajax data.
- Continuing to hire across engineering, sales, and customer activation to scale the product and go‑to‑market.

## Why Work Here

- **Mission‑driven**: Removing the “worst part of a lawyer’s day” – a clear, emotionally resonant problem.
- **Perks**: Not explicitly listed, but small startup environment typically includes equity, early‑stage growth opportunities, and direct exposure to founders.
