Go-to-Market Engineer

About the Role

This is not a single-company role. You will work hands-on across multiple portfolio companies as a resourceful, AI-native operator — using modern tooling and vibecoding to build systems, run outbound campaigns, and own the full cold email stack. The mandate is clear: identify what is working across lead gen and demand gen channels, cut what is not, and turn proven approaches into scalable playbooks deployable across the broader platform. You will be technical enough to architect GTM systems and run experiments — but the focus is growth outcomes, not engineering for its own sake.

What You'll Own

• Work hands-on with portfolio companies to diagnose and improve top-of-funnel growth — across paid, events, outbound, organic, and other demand gen channels

• Use AI tools and vibecoding to build internal applications, automations, and workflows that accelerate GTM execution and outreach at portfolio companies

• Design and execute cold email infrastructure end-to-end — subdomain setup, inbox warmup, deliverability monitoring, sequence creation, A/B testing, and KPI tracking

• Own CRM operations (HubSpot or equivalent) — data hygiene, pipeline workflows, views, and reporting across portfolio companies

• Build and run GTM experiments, identify what drives results, and turn proven approaches into repeatable playbooks deployable across the broader portfolio

• Continuously experiment with new AI tools and approaches to compress research and outreach timelines

What We're Looking For

• Someone who builds things — you default to "let me prototype this" over "let me write a spec for this"

• Comfortable vibecoding — using AI coding assistants to ship functional tools, scrapers, dashboards, or integrations without a traditional engineering background

• Strong background in lead gen, demand gen, or GTM systems — you have built and operated growth channels, not just managed them

• Strong working knowledge of HubSpot (or comparable CRM) including list management, workflows, properties, and reporting

• Hands-on experience with cold email tooling (Instantly, Smartlead, Apollo, or similar) and a solid grasp of deliverability best practices — DNS records, inbox rotation, sending limits

• Able to move quickly across multiple business contexts — comfortable context-switching between portfolio companies with different models, markets, and maturity levels

• NYC-based or willing to be — the team operates in person
