iOS Product Engineer (Contract, Fractional)

• Own and polish our iOS app in Swift and SwiftUI so it is reliable and beta ready, including a clean Bluetooth connection to the sensor and solid data sync.
• Set up our analytics and experiments with PostHog so we can see how users actually move through the app, put features behind flags, and run simple A/B tests.
• Extend our web coach dashboard in Next.js and TypeScript so coaches and players can see their training data.
• Help decide what to build next as beta feedback comes in.

What we are looking for

• You have shipped a real iOS app you can show us, ideally Swift and SwiftUI.
• You can own web frontend work too, in Next.js, TypeScript, and React.
• A product brain: you have shipped a feature, watched how people used it, and changed something because of it.
• You like early stage ambiguity and owning things end to end.

Nice to have: Bluetooth/CoreBluetooth, PostHog/Amplitude/Mixpanel + A/B testing, sports tech or wearables., The details: Sprint up front (30 to 40 hrs/week for 6 to 8 weeks), then lighter ongoing (8 to 12 hrs/week). Columbus is a strong plus. Real path to a full time lead role as we close our raise. Standard IP assignment agreement.

Do you have experience in TypeScript?, We are hiring one strong iOS engineer who also thinks like a product builder to help us get to beta and learn fast from real users.
