About Manifest
Manifest OS is the leading AI-native company on a mission to replace the billable hour and make legal services more accessible for American businesses and consumers. We power the next generation of AI-native law firms with one unified global brand, a proprietary technology platform, and a centralized back office — enabling lawyers to eliminate the administrative burden and focus on delivering exceptional outcomes for their clients. Manifest OS has raised a $60M Series A from Menlo Ventures, Kleiner Perkins, First Round, and Quiet Capital.
About The Team
GTM Data & Operations powers Manifest's go-to-market motion across marketing and sales. The team owns measurement, reporting, and the systems and automations the GTM org runs on, built on a central data platform owned by a separate team. Small team, company-wide impact: every growth decision runs through this work.
About The Role
You'll own marketing's analytics and measurement and build the tooling that acts on it. On the analytics side: the reporting, attribution, and journey work that tells the team what's actually driving conversion, so marketing can launch, measure, and iterate with confidence instead of guessing. On the build side: the apps, automations, and AI agents that put those answers to work, streamlining our partners, webinar and content motion; automating manual reporting and lead-routing; and extending the conversational BI agent so anyone can ask a data question and trust the answer.
You'll build on a centralized data platform, partner closely with RevOps, and treat marketing and sales as your customers. It's an early, high-ownership seat, in person in NYC, with room to shape how go-to-market runs on data as the company scales.
What You’ll Do
You want to be at the tip of the spear of a once-in-a-generation shift in how professional services are delivered. You love turning messy, manual work into clean automated systems. You want to own a function end to end at a fast-moving company, in person, alongside a great group of people.
This is not for you if....

What You’ll Do
- Own marketing analytics and measurement: reporting, attribution, the funnel and journey, so the team sees what's working and iterates
- Build GTM tooling and internal apps, e.g. operationalize the partner hub (each partner logs in to see their stats, webinar lineup, and personalized content)
- Automate the manual work, reporting pulls, lead routing, lifecycle and campaign ops, increasingly with AI and agents
- Own web and product analytics for growth: reconcile Amplitude with GA4, stand up AEO reporting as search shifts to AI answer engines, stitch the full visit-to-signed-case journey
- Build toward conversational BI: curated datasets and AI-readable docs so anyone can ask a data question and trust the answer (a v1 agent already exists)
- Partner with the data platform team (owns the warehouse) and RevOps
- Strong builder: ships production apps and automations end to end (TypeScript / Python / SQL)
- AI-native by default: builds with LLMs and agents; bonus for shipped data or AI products
- Analytical: can own measurement and reporting, strong SQL and BI, turns a business question into a trusted answer
- GTM/marketing data a plus: CRM, paid media, web and product analytics, attribution
- Bias to build, scrappy, thrives in ambiguity with high ownership
- New York City, in-office 5 days/week

This is not for you if....
- You want to only analyze, not build, this role is both
- You need a mature platform and clean data handed to you
- You're looking for remote or hybrid; we build in person in NYC
