GTM Engineer

Pogo Technologies

Priorities may shift quickly. Oftentimes, we're tackling very ambiguous problems that don't have clear-cut answers. At times, you'll need to build things in a day: we live and breathe a value called "Calculated Speed". We don't have structured management (yet!). We expect more than 9 to 5 - raw hours make an impact at our current stage. We trust each team member to create a flexible work schedule that allows them to be most productive while accommodating other priorities outside of work. We also strongly encourage time off to recharge the batteries: in addition to unlimited PTO, we've implemented a minimum 20 days vacation policy.

Role Description As the first GTM Engineer at Pogo, you'll partner with our Growth, Sales, Design, and Engineering teams to build AI-powered systems that compound revenue. You'll work on our enterprise AI SaaS product as both a builder and an operator: shipping code that drives pipeline and conversion. - Ship AI-powered workflows that scale our growth and sales motions as a competitive advantage. - Audit our existing GTM stack, identify the gaps and redundancies, and start shipping against them fast. - Embed with our sales and growth teams to turn their best plays into systems the whole org can run on. - Build internal tools and agents that replace manual workflows - lead routing, enrichment, outbound personalization, account research, content distribution, attribution. - Know when to reach for off-the-shelf tools and when to build something custom. - Partner closely with engineering and design to test new features, give feedback, and dogfood our own AI capabilities for GTM use cases. - Publish playbooks and internal guides so wins propagate across the team. Qualifications - Likely 2-5 years of professional software engineering experience, with at least some of that applied directly to GTM, growth, or revenue systems. - You're a heavy user of AI tools like Claude Code, Cursor, or Codex and have shipped non-trivial things with them. - You've built with LLMs and AI agents - think RAG, evals, tool use, prompt engineering. - You're hands-on with the modern GTM stack (Clay, HubSpot or Salesforce, Apollo, Cargo, Gong, Outreach/Instantly, etc.) and can navigate APIs, webhooks, and integrations fluently. - You have strong product and design taste - the internal tools you build should feel as polished as the product. - You think in systems and like turning messy operational problems into clean, automated ones. - You have real commercial instinct - you can sit in a sales call or read a growth dashboard and immediately see where leverage exists. - You communicate clearly across technical and non-technical stakeholders, especially when things are ambiguous. - You've built and maintained production systems used by real users (internal users count). Requirements - Experience at early-stage startups or building your own products. - You've shipped AI agents that moved an actual revenue metric, not just demos. - Background in RevOps, Marketing Ops, or Sales Engineering before moving fully into building. Benefits - Ship real systems that get real usage and move real numbers - pipeline, conversion, retention. - Sit at the center of the company. Partner with Growth, Sales, Design, and Engineering. - Use the latest tech. Build with the latest coding tools, LLMs, and GTM platforms. - Move fast. Ship weekly and get rapid feedback from the teams using what you build. - As the first GTM Engineer at Pogo, you'll shape what this function looks like at Pogo as we scale.
