Company Description
Humaans is a $20M Series A London-based startup building AI-powered infrastructure for the workplace, backed by Y Combinator and the founders of Slack, Figma, and Shopify.
Job Description
You will build the automated infrastructure powering Humaans' go-to-market engine, sitting between RevOps, Sales, and Marketing. Instead of manual outreach, you’ll design data pipelines, AI agents, and enrichment workflows using Clay and HubSpot to find and engage customers at scale, replacing rep-dependent processes with high-leverage, non-linear systems.
Location
London, UK
Why this role is remarkable
- Full ownership of the GTM engineering stack, moving beyond standard RevOps reporting to build automated systems that drive real revenue growth.
- Join a $20M Series A team backed by legendary operators including Lachy Groom and the founders of Slack, Figma, and Shopify.
- Incredible career leverage at a high-bar startup redefining HR tech through an AI-native platform that orchestrates workflows across HR, IT, and Finance.
What You Will Do
- Architect and maintain complex data pipelines and enrichment workflows using Clay to turn raw signals into prioritized, actionable target accounts.
- Own the technical outbound infrastructure, managing cold email deliverability, inbox health, and large-scale personalization through AI agents and custom scripts.
- Partner with GTM leadership to identify manual bottlenecks and ship automated solutions in days, connecting systems via APIs and scripting (Python/JS).
Reasons to use Rodeo
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
It searches the market for you
Every day your agent scans the market matching roles against what actually matters to you, not just keywords on a CV.
Only hits
No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.
The ideal candidate
- Hands-on experience building with a modern GTM stack, specifically Clay and HubSpot (or Salesforce), and a deep understanding of outbound motion.
- Proficient in SQL and a scripting language like Python or JavaScript to handle API integrations and data manipulation independently.
- A systems thinker with an experimental mindset who uses AI coding tools like Cursor or Claude Code to build and ship production-ready workflows.

We never post fake jobs
This isn't a trick. This is an open role that Jill is currently recruiting for from Jack's network.
Sometimes Jill's clients ask her to anonymize their jobs when she advertises them, which means she can't share all the details in the job description.
We appreciate this can make them look a bit suspect, but there isn't much we can do about it.
Give Jack a spin! You could land this role.
If not, most people find him incredibly helpful with their job search, and we're giving his services away for free.
