Give our agency and designer direction, make sure we're targeting the right people with the right messaging, hold them accountable to ROI targets. * Run our conference machine. Pick the events with high ROI, build the target lists, run booth ops and follow-up, and measure every dollar. * Build the referral engine. Hundreds of law firms love us and about half our revenue already starts with word of mouth. Turn that from something that just happens to us into something we control: rewards programs, systematic asks, partner enablement. * Run an AI-first content factory. We use Claude Code and Codex aggressively - it's easy, but undifferentiated to churn out pretty-good drafts. To make the final copy something a skeptical managing partner will take time out of his day to read, you'll bring taste, pick the topics, and enforce our voice. Lawyers are wonderful customers to create content for - they're literate and highly discerning. They're also trained to notice small errors and are very averse to poor writing. The bar is high, and so are the potential rewards. * Get us into the rooms lawyers are already in. Book our founders and customers onto podcasts, newsletters, and CLE panels, and make each placement measurable. * Run our founder's LinkedIn like a channel. Write posts, curate testimonial clips, and get it seen by a growing network of exactly the right lawyers. If you decide the ROI is there, manage a LinkedIn ghostwriter instead. * Test new channels. Prospects already tell us they found Ajax by asking ChatGPT and seeing our posts on LinkedIn. Own our AEO, run small-dollar tests of paid ChatGPT ads, evaluate whether paid LinkedIn content is worth leaning into, and more. * Own the scorecard. Monthly channel review with real kill/scale decisions. You'll inherit clean attribution and a working framework - your job is to run it and act on it. Who you'll be working with: * Jack Weinberger Founder, GTM (Yale, PE, Chief of Staff at Humming Homes) * Alex Weinberger Founder, Eng. & Product (Amazon, Founding Eng. at dub) * Roger Jin - Founding Senior ML Engineer (Harvard, Carnegie Mellon, nference) * Sophia Fein - Founding Customer Activation (Mintz Levin, KPMG) * Tyler Argov - Founding Customer Activation (Investment Banking Analyst at Raine) * Brandon Schneider - Founding Customer Activation (Litigation at Mintz Levin, startup) * Siyou Pei, Ph.D - Founding Product Engineer (UCLA Ph.D) * Andrew Sheeler - Full Stack Engineer (Harvard, AngelList) * Nat Fernelius - Full Stack Engineer (ML at EY) * Andrew Emil- Full Stack Engineer (Google, Co-founder at Xent Labs) * David Esterlit- Account Executive (Princeton, founded and sold his own furniture wholesaling company) * Tajus Gopal - SDR (Rippling) Who you are You're probably a generalist - you've done some demand-gen with concrete targets, worked the events circuit, and know how to edit copy. If you can do some but are excited to own it all, that can work too. You've owned a pipeline number at an early-stage B2B company. Marketing fed a sales team, and you can tell me the meetings and dollars you moved - and how you measured them. You write and edit at a professional-audience bar. Our buyers argue for a living. You can catch overreaching claims, tell when copy is AI-generated, and make lawyers feel like they're reading something written by a peer. You're credible in a room full of lawyers. Conferences are much of the job. You can hold a conversation with a managing partner at a booth, at a dinner, on a panel-prep call. You're AI-native. You use agents the way everybody else at Ajax does - to help 1 person do the work of 4, without letting the quality slip. You want to build, not decorate. You may have gathered from the rest of this post - we have a lot of low-hanging fruit. We don't need brand refreshes or awareness spend just yet; focus on pipeline, revenue, and ROI. You're not afraid to get your hands dirty. Some days this job looks like making the case to reallocate $100k of spend to a higher-ROI channel - sometimes it's booking hotel blocks in Nashville for an upcoming conference. The scoreboard doesn't care, and neither do you. Who you aren't If you're looking to sit at a high altitude and just manage a team, or if you want to specialize deeply in just one area, this one probably isn't for you. ## Related Videos - [Coffee with Developers](https://www.wearedevelopers.com/videos/354-coffee-with-developers) - [Launching a marketplace on-time: A lesson in taking shortcuts using spreadsheets!](https://www.wearedevelopers.com/videos/477-launching-a-marketplace-on-time-a-lesson-in-taking-shortcuts-using-spreadsheets) - [WeAreDevelopers LIVE - Local Transcriptions with Open-Source AI](https://www.wearedevelopers.com/videos/1905-wearedevelopers-live-local-transcriptions-with-open-source-ai) - [ Evaluating AI models for code comprehension](https://www.wearedevelopers.com/videos/1462-evaluating-ai-models-for-code-comprehension) - [HR ROBO SAPIENS: Decoding AI Agents and Workflow Automation for Modern Recruitment](https://www.wearedevelopers.com/videos/1470-hr-robo-sapiens-decoding-ai-agents-and-workflow-automation-for-modern-recruitment) - [Protector Of The Realm](https://www.wearedevelopers.com/videos/591-protector-of-the-realm) ## Related Articles - [Dev Digest 120 - Apple and peers](https://www.wearedevelopers.com/magazine/455-dev-digest-120-apple-and-peers) - [Dev Digest 139 - Soft and hard queries](https://www.wearedevelopers.com/magazine/487-dev-digest-139-soft-and-hard-queries) - [Dev Digest 131 - AI'm not sure about OSS](https://www.wearedevelopers.com/magazine/472-dev-digest-131-ai-m-not-sure-about-oss) - [Dev Digest 136 - No JS(on) of mine](https://www.wearedevelopers.com/magazine/482-dev-digest-136-no-js-on-of-mine) - [Dev Digest 138 - Are you secure about this?](https://www.wearedevelopers.com/magazine/486-dev-digest-138-are-you-secure-about-this) - [Dev Digest 121 - AI goes offline](https://www.wearedevelopers.com/magazine/456-dev-digest-121-ai-goes-offline)
