GTM Engineer

About this role

ABOUT US

Humaans is building the next generation of infrastructure for the workplace; software designed for companies that are scaling fast, operating globally, and pushing into new boundaries.

What started as a system of record has evolved into a broader platform for operating people globally. With Athena, our agentic AI layer, Humaans moves beyond data management into intelligent orchestration, connecting workflows across HR, IT, Finance, and Operations so organisations can act faster and with greater confidence, redefining how work gets done.

We work with ambitious teams across Europe and the US, from AI-native companies like Lovable, Poolside, Fyxer AI, and Tandem Health, to established, high-growth organisations scaling internationally and through acquisition, including Quantexa, Sellpy, Manychat, Gigs, Croud, and Threecolts. These teams don’t buy software for features,they buy leverage. The ability to run faster, cleaner, and with more control as complexity compounds.

To date, we’ve raised $20m in venture funding from some of the most respected founders, operators, and funds in technology: Lachy Groom (Physical Intelligence), Stewart Butterfield (Slack), Tobias Lütke (Shopify), Dylan Field (Figma), Jeff Weiner (LinkedIn), Claire Johnson (Stripe), Oliver Jay (OpenAI), Jay Simmons (Bond) as well as Y Combinator, Moonfire, Frontline Ventures, Pathlight Ventures, and Exor.

If you have massive ambition and want to work on a hard problem, with a small team that moves fast, at a moment when the category is genuinely up for grabs - this is it.

ABOUT THE ROLE

Revenue teams used to scale by adding people. Now they scale by building systems. We're looking for a GTM Engineer to own the infrastructure behind how Humaans finds, engages, and converts customers, turning our go-to-market strategy into automated systems that run at scale.

This is a builder role, not a reporting role. You'll sit between RevOps, Sales, and Marketing and own the connective tissue: the data pipelines, enrichment workflows, signal detection, lead scoring, routing, AI agents, and outbound infrastructure that decide which accounts we pursue, what we know about them, and what happens next. When a process is manual, slow, or rep-dependent, you replace it with a system. Your output scales non-linearly, because the system does the work, not the headcount.

OUR GTM STACK

Our GTM stack runs on HubSpot as the system of record, with Clay as the orchestration layer wiring together dozens of data providers, enrichment sources, AI models, and our own internal tools into automated workflows. You'll have dozens of tools at your disposal to build with, from enrichment and outbound platforms to call intelligence, AI coding tools, and our own internal tooling, plus the latitude to add new ones when they earn their place. We obsess over clean data and reliable systems, and we move fast by building on high quality foundations rather than stacking fragile workarounds.

YOUR DAY TO DAY

- Own the data foundation: keep our CRM trustworthy with automated enrichment, hygiene routines, and clear ownership rules

- Build enrichment and scoring workflows that turn raw firmographic and signal data into ranked, ready-to-action target lists

- Design signal-based plays: detect the right buying signals and events as they happen, then trigger the right outreach at the right moment

- Own cold email as our primary outbound channel: build and protect the sending infrastructure, manage deliverability and inbox health, personalise at scale, and instrument it so you're the first to know when something breaks

- Deploy AI agents for research, personalisation, and CRM updates, with guardrails that protect quality and brand

- Connect our GTM tools through their APIs, deciding what the source of truth is for each field and how data flows between systems

- Launch new outbound campaigns continuously, run structured tests, read the results, and feed what you learn back into the system so it keeps improving

- Partner with SDRs, AEs, and leadership to find bottlenecks, ship solutions in days, and scale what works

- Design structured tests with defined success metrics up front, kill what underperforms fast, and double down on what works

- Treat copy as a testable variable: systematically test subject lines, opening angles, and CTAs, then roll winners back into templates and agent prompts

- Operate at volume: manage thousands of leads flowing through the system every day without letting data quality or targeting slip

SKILLS

- Systems thinker with a commercial bias: you judge every workflow by whether it actually helps close a deal

- Copywriting backed by testing: you write outbound that books meetings and prove it through reply and positive-reply rates rather than opens

- Hands-on experience with a modern GTM stack (Clay or equivalent, HubSpot or Salesforce, plus enrichment and sequencing tools)

- Comfortable enough with SQL and a scripting language (Python or JavaScript) to solve problems independently; reading API docs, handling auth, and chaining calls doesn't scare you

- Fluent with AI coding and automation tools (Claude Code, Cursor, n8n, Zapier) and able to build, test, and ship agents and workflows end to end

- Strong understanding of the outbound motion: ICP definition, lead scoring, deliverability, and what good outreach actually requires

- Experimental mindset: you validate signals, measure everything, and turn feedback loops into better systems

- You learn by tinkering. Background matters less than a track record of building things revenue teams actually use

Many of the best GTM Engineers come from SDR, RevOps, growth, or product backgrounds. If you've been the person quietly wiring Clay into your CRM and automating your own pipeline, this is the role for that instinct.

This is an in-person role. Our GTM team comes together in the office Monday through Thursday, while most of the team collaborates…
