**Role Description **

We are looking for a Senior App Developer who can build at an elite level.

This is a contract-based remote role for someone who can take ownership of the product and execute fast. You will be responsible for building both the web platform and native mobile apps (iOS + Android) from the ground up.

This is not a “follow instructions” role.

**Bonus **

•	Experience in fitness, mobility, health, or performance

•	Experience building 0 → 1 products or startups

⸻

**Who This Is NOT For **

•	Developers who need constant direction

•	Slow executors

•	People who are okay shipping “good enough”

⸻

Someone who wants to build something category-defining.

Someone who takes pride in creating beautiful, fast, world-class products.

Someone who wants to be part of something that genuinely changes lives.
