Growth Marketing Manager (GTM Engineer)

About the role Reporting to the Marketing Director, you will build the demand engine that turns Supercritical 's target account list into engaged buyers, and you will build it with AI rather than with headcount. Your job is to figure out how to combine creativity, systems thinking, AI, and a handful of Sales and Marketing people into systems and campaigns that deliver on commercial goals. This is a builder role through and through. Supercritical sells carbon removal to the world's largest companies through 12+ month cycles against a constrained TAM. That is a small, senior, sophisticated buyer pool where volume outbound does not work but precision does. You will sit in a marketing team of five alongside comms, content, events, product marketing, and policy, and work daily with the account directors and our commercial director. Our product team can support you on infrastructure, but this is a commercial role using technical tools, not a software engineering role. What you'll be doing Build the outbound and nurture engine: Own the systems that move accounts from unaware to engaged to sales-ready: signal capture, scoring, sequencing, and escalation. Design it so an engaged account gets a next step without waiting for a rep. Build campaigns that personalize at account level using our own data and research, then measure whether personalization actually changed behavior. Ship small tools and calculators that earn attention and generate first-party data. Our SBTi calculator is the template: a mini product built with Claude Code, launched for engagement, then wired into outreach. Ensure funnel truth: Build on existing account engagement tracking in HubSpot. Stand up coverage and pipeline reporting by account tier that runs without manual work. Own data quality across enrichment, target list management, and CRM hygiene. Decide what to fix, what to automate, and what to leave alone. Make events compound: Own event-driven demand: pre-event target lists and outreach, post-event
