Founding engineer

Founding Engineer — Golf Coach Now (Equity‑Only, 90‑Day Build Sprint)

Golf Coach Now is creating a new market and a new category in golf learning: a physics‑based correction engine that teaches golfers the right move before the next swing. This is not a “practice app,” not a “drill library,” and not a “motor‑learning tool.” This is a deterministic learning engine — a new category in sports technology.

We are preparing to build Version 1 and bring it to market in 90 days.

To do that, we’re looking for a Founding Engineer who wants to build something real, fast, and category‑defining.

You will work directly with the founder, who retains product control and vision. As the company grows, this role evolves naturally into CTO.

This is an equity‑only founding role — an alternative to having the product built by a professional development firm. If you want to build something meaningful from the ground up, this is your lane.

⭐ What You’ll Build (V1 Scope)

Each item begins with a Guided Link.

- React front‑end — clean UI, simple flows, intuitive user experience

- Python correction engine — rule‑based physics logic for swing correction

- Backend + API — lightweight services for user accounts, data, and subscriptions

- Basic instructor interface — early tools for LPGA/PGA pros

- User onboarding + subscription flow — simple, reliable, scalable

- Data storage + analytics — early tracking for swing inputs and corrections

This is a tight, clean, 90‑day build — not a sprawling platform.

⭐ Skills Required

- React.js — front‑end UI

- Python — correction engine logic

- Java or Node — backend services

- SQL — simple, reliable data storage

- API design — clean endpoints for V1

- Version‑1 product experience — MVPs, prototypes, fast builds

- Ability to work directly with a founder — clarity, communication, execution

If you’ve built MVPs, prototypes, or early‑stage products, you’ll thrive here.

⭐ Hours Needed for V1 Delivery (90‑Day Sprint)

A realistic founding‑engineer workload:

- 300–450 hours total

- React front‑end: 80–120 hours

- Backend + API: 80–120 hours

- Python correction engine (ruleset): 60–100 hours

- Onboarding + subscription flow: 20–40 hours

- Testing + fixes: 40–60 hours

- Deployment + hosting: 20–30 hours

This is exactly what one strong engineer can deliver in 90 days.

- Someone who loves shipping product, not debating theory

If you want to build something that becomes the default way golfers learn, this is your moment.
