About the role

GTM Engineer to own the infrastructure behind how Humaans finds, engages and converts customers, turning go-to-market strategy into automated systems at scale. Works across RevOps, Sales and Marketing to build data pipelines, enrichment, scoring, AI agents, and outbound infrastructure.

Responsibilities

  • Own the foundations of our GTM data, keeping HubSpot trustworthy through automated enrichment, hygiene routines and clear ownership rules
  • Build enrichment and scoring workflows that turn raw firmographic, behavioural and signal data into ranked, ready-to-action target accounts
  • Design signal-based plays that identify meaningful buying signals and trigger the right action at the right moment
  • Own cold email as a core outbound channel, including sending infrastructure, deliverability, inbox health, personalisation and monitoring
  • Deploy AI agents for research, personalisation, CRM updates and other repetitive GTM workflows, with guardrails that protect quality and our brand
  • Connect GTM tools through APIs, defining sources of truth and designing how data moves reliably between systems
  • Launch new outbound campaigns continuously, run structured experiments and feed what you learn back into the system
  • Treat copy as a testable variable, systematically experimenting with subject lines, opening angles, messaging and CTAs, then incorporating what works into templates and agent prompts
  • Partner closely with SDRs, AEs and leadership to identify bottlenecks and ship solutions in days rather than waiting for lengthy projects
  • Design experiments with clear success metrics, stop investing in what underperforms and scale what works
  • Operate at volume, managing thousands of leads moving through our systems without compromising data quality or targeting
  • Continuously look for places where automation, AI or better infrastructure can give the GTM team more leverage

Qualifications

  • A systems mindset paired with strong commercial instincts
  • Hands-on experience with a modern GTM stack, including tools such as Clay, HubSpot or Salesforce, enrichment providers and sequencing platforms
  • Strong understanding of outbound, including ICP definition, targeting, lead scoring, deliverability and what effective outreach actually requires
  • The ability to write effective outbound copy and improve it through testing, using reply and positive-reply rates rather than vanity metrics to understand what works
  • Enough SQL and Python or JavaScript to solve problems independently, alongside confidence reading API documentation, handling authentication and connecting systems
  • Fluency with AI coding and automation tools such as Claude Code, Cursor, n8n or Zapier, with the ability to build, test and ship workflows end to end
  • An experimental mindset. You define what success looks like, test assumptions, measure results and use feedback loops to make systems better
  • A bias towards building. You learn by tinkering, shipping and seeing what happens rather than waiting until you know everything
  • Strong attention to detail, particularly around data quality, automation reliability and the downstream consequences of changes you make
  • A track record of building systems that revenue teams actually use. Your background could be SDR, RevOps, Growth, Product or something else entirely
