What You’ll Be Doing

We’re building for the agentic era of AI - where software doesn't just support teams, it acts with autonomy to elevate them. As a GTM Engineer, you’ll build the systems that power smarter, faster go-to-market teams. You’ll work closely with Sales and CS to deploy automation, surface insights, and orchestrate workflows across the revenue engine.

This is a hands-on technical role at the intersection of automation, RevOps, and customer engagement. Your work will focus on implementing scalable infrastructure in HubSpot and other tools to detect signals to sell, spot signals to retain, and support lean teams with automation that drives outcomes. You’ll be a key builder enabling GTM systems that act - not just track.

What Success Looks Like

• Revenue signals are automated and actionable: You’ve instrumented systems that detect leads (e.g. intent data, usage thresholds) and renewal or churn risks (e.g. support interactions, usage drop-offs), and routed them to the right teams at the right time.
• RevOps infrastructure runs smoothly: You’ve owned and optimized HubSpot and its integrations with Zoominfo, Intercom, Stripe, and Customer.io to reduce manual work, ensure clean data and insight-driven GTM execution.
• Sales cycles speed up: From qualification to CRM hygiene to meeting prep, reps are spending less time on admin and more time closing.
• Expansion is proactive: You’ve built systems that surface upsell opportunities based on real customer behavior, feeding Customer Success with the context they need to act early and effectively.
• Handoffs are seamless: Every stage transition - SDR to AE to CSM - comes with AI-generated summaries and next-step guidance, so no context is lost and every customer feels known.

• Use APIs, webhooks, and no-code tools to build scalable, event-driven automations
• Keep systems clean, reliable, and insight-rich across the funnel
  
  

• Identify recurring bottlenecks and automate them out of existence
• Operationalize AI insights to align Sales, Success, and Marketing around shared signals
• Lay the groundwork for future GTM automation, including self-serve experimentation
