Job description
- You'll write the code that turns developers discovering the product into developers who can't live without it.
- This is a full-stack engineering role pointed entirely at growth: you'll own the signup, activation, onboarding, and conversion experience, and you'll be measured on the funnel metrics you move, not just the features you ship.
- You'll instrument, experiment, build, and iterate on the product surfaces that drive the company's PLG motion. You'll own real conversion outcomes from day one.
Responsibilities
- Own the growth surfaces end to end: signup, activation, onboarding, and conversion.
- Instrument the funnel, run experiments, and ship changes that move real metrics.
- Build full-stack, from the frontend a developer first touches to the backend that powers it.
- Treat conversion and activation as your numbers—you own them, measure them, and move them.
- Work close to the data, form hypotheses, test them, and iterate quickly on what works.
Requirements
- 5–12 years of experience as a full-stack engineer, including hands-on growth work as an IC at an early- or growth-stage startup.
- You're a strong full-stack engineer who's worked on growth or PLG products.
- You've personally owned a conversion, activation, or funnel metric and moved it—not just shipped features someone else measured.
- You think like a scientist: hypothesis, experiment, measure, iterate. You've run real A/B tests and can discuss what you learned, including when they didn't go as planned.
- Strong experience with React, TypeScript, Next.js, and Node.js.
- You've worked on developer-facing products such as SDKs, playgrounds, APIs, or other developer tools and understand how developers actually adopt products.
- You're comfortable operating without detailed specs and have the product judgment to help determine what should be built.
- You use modern AI coding tools as part of your regular engineering workflow.
- You have a track record of staying with your work long enough to see it through.
- You move fast and close the loop—you'd rather ship, measure, and iterate than perfect something on paper.
- Experience shipping in-product growth surfaces at a developer-tools or SaaS company, such as onboarding, activation, upgrade flows, or in-product guidance.
- Experience with Tailwind, Vercel, PostgreSQL, Python, SQL, or product analytics tools.
- Experience building with LLMs in production, including prompt engineering, tool use, or inference pipelines.
- Experience with LLM APIs.
- Experience building internal tooling adopted by growth or product teams.

About Morgan Pinnacle Group
We're a fast-growing AI infrastructure and developer-tools company building technology that turns web content into clean, structured data that AI applications can use. We reached 8 figures in ARR in our first year and have more than doubled since. We're a small team punching far above our weight, with strong adoption among developers and AI-native companies. Everyone here owns a real piece of the product and company, end to end, and runs it themselves—no hiding behind process or headcount. This is a place for people who want to work at the frontier: an AI company building infrastructure other AI companies run on, not one bolting AI onto an existing product. We move fast, go deep, and are building foundational tools for how AI systems access and use data from the web.
