Grew up in a small town and had to work extra hard to get my foot in the door working on cool tech startups. My first job at age 15 was fixing iPhone screens in the mall. Then I scooped ice cream at Cold Stone Creamery and bussed tables at a local airport restaurant to pay for college. 

After football practice in high school I'd be learning how to code on CodeAcademy. People thought I was a nerd. 

Fast forward 10 years -- I've built multiple apps, b2b SaaS, internet businesses, websites, and e-commerce businesses that have generated over $100m collectively. 

I got to work remotely, travel to 12+ countries, invest in real estate and stocks and built a fruitful living for myself. 

Learning how to build apps changed my life. Now I’m on a mission to teach 10,000 people how to build apps.

🚨 We’re hiring an AI Prompt Engineer at CloserCoach  

We’re running 300+ AI mock sales calls per day — and that number is about to explode as we roll out our desktop app and 10x our marketing spend. 

We’re looking for someone who lives and breathes prompts.

This role is not about “writing clever ChatGPT prompts.”

It’s about shipping production-grade AI systems that real sales teams rely on every day.

What you’ll own:
	• Fine-tuned prompt systems for each B2B customer
	• Few-shot + multi-step prompt architectures
	• Custom RAG pipelines tailored to sales workflows
	• Continuous model evaluation & iteration using Langfuse
	• Improving realism, objection handling, scoring accuracy, and coaching quality at scale

You should be obsessed with:
	• Prompt reliability under real user behavior
	• Edge cases, drift, hallucinations, and failure modes
	• Measuring prompt/model performance (not vibes)
	• Iterating fast, testing constantly, and shipping improvements daily

You’ll thrive here if you:
	• Think in systems, not single prompts
	• Have built with few-shot prompting, structured outputs, and custom RAG
	• Care deeply about realism and outcomes
	• Want your work used hundreds of times per day by real sales teams

We’re building one of the most advanced AI sales training platforms on the market — and prompt engineering is a core moat, not an afterthought.

If this sounds like you (or someone you know), DM me.
