Job description

Build growth engines with a team that's pushing the edge.

We're GTMBase, an AI-first RevOps and GTM agency. We build the systems, automations, and data infrastructure that power how modern B2B companies find, qualify, and convert their best customers. Deep RevOps expertise. AI-first execution.

We work with a limited number of clients and go deep rather than wide. You'll be embedded with a handful of companies, understanding their business, designing their GTM architecture, and building systems that compound over time.

This is a contract / part-time role with a path to full-time.

Tasks

• Design and build GTM systems: data enrichment pipelines, lead scoring models, routing logic, signal-based workflows. Clay is your primary canvas.
• Find and connect data sources: discover new APIs, databases, and enrichment providers that give our clients an information edge. You're always hunting for better data.
• Architect CRM and automation infrastructure: HubSpot, Salesforce, n8n, Clay whatever the client needs. You wire it all together so nothing falls through the cracks.
• Build AI-powered workflows: use LLMs (Claude, GPT) and AI agents to automate research, personalization, qualification, and analysis at scale.
• Work closely with clients: run feedback loops, present your work, and translate messy business problems into clean, repeatable systems. You'll build real relationships, not just deliverables.
• Push the frontier: R&D is part of the job. Test new tools, new techniques, new approaches. Share what you learn with the team. We move fast because everyone brings something new to the table.

Requirements

Must-haves

• Clay expertise: you've built real things in Clay. Portfolio work, client projects, or personal experiments that show you know your way around the platform.
• AI-first mindset: you use AI tools daily, not as a novelty but as core infrastructure. You reach for Claude or GPT before you reach for a spreadsheet. You're building with AI, not just prompting it.
• Systems thinker: you see the whole picture. Data flows, dependencies, edge cases, failure modes. You design systems that are robust, not just functional.
• Natural problem solver: when something doesn't work, you figure it out. You read docs, reverse-engineer APIs, test hypotheses, and find a path forward. Nobody needs to hand you a playbook.
• Self-directed but team-oriented: you can operate independently and drive projects to completion without micromanagement. But you also thrive in a team, share knowledge openly, and make the people around you better.
• Constantly learning: this space moves fast. New tools, new data sources, new techniques every week. You keep yourself up to speed because you're genuinely curious, not because someone told you to.
• Technical connector: you can find new data sources, connect APIs, evaluate and integrate new tools into a client's tech stack. You're comfortable reading API docs and building integrations.

Nice-to-haves

• Claude Code expertise: if you're already building with Claude Code, agentic workflows, or AI-assisted development, you'll fit right in. This is where we're heading.
• HubSpot or Salesforce admin experience: CRM architecture and administration chops are a strong plus.
• Agency or consulting background: experience managing multiple client relationships and context-switching across projects.
• RevOps or GTM foundation: understanding of pipeline metrics, attribution, funnel analysis, and revenue operations principles.

Benefits

• Competitive Salary
• Work with a small, senior team that's building the future of GTM, not maintaining legacy systems.
• Deep, meaningful client work. You'll see the direct impact of your systems on real businesses.
• Exposure to the most advanced GTM tooling and techniques in the market. We're setting the pace.Real ownership. No ticket queues. No "just execute this spec." You design, build, and iterate.
• A team that values builders. If you've ever felt like the smartest GTM person at a company that didn't appreciate what you could do, this is your place.

We care about what you can build, not where you went to school.

As part of your application, share your Clay tables: record a short walkthrough (Loom or similar) showing us what you've built and how you think about it. This tells us more than any resume.

For shortlisted candidates, we'll do a paid build challenge that mirrors real client work.
