Contract iOS Engineer (Fractional, 2–4 Weeks)
Summary
Contract iOS engineer for a 2-4 week fractional engagement to finalize a pre-launch cycling performance app, focusing on app-state gating, StoreKit 2 subscriptions, and onboarding bugs, working directly with the founder in real-time pair debugging.
Compensation: $125k – $166k • No equity
US-based candidates only — this role requires real-time collaboration during US business hours
About Klizmo: Klizmo is a native iOS app for competitive and structured-training cyclists, built around precise, data-driven performance feedback rather than social features, leaderboards, or gamification. We're a pre-launch startup moving toward public availability this fall, with real users already using the product.
The role: A short, high-intensity fractional engagement to close out the final iOS surface before public launch. Backend is done — this is squarely a client-side sprint. You'd work directly and synchronously with the founder — live pair-debugging, architecture review, and hands-on device testing — rather than picking up isolated tickets.
What's left to close:
- App-state gating logic around onboarding needs hardening — urgent
- StoreKit 2 subscription/entitlement hardening (missing background transaction listener) — urgent
- A handful of real onboarding bugs (post-auth navigation, duplicate-email handling, modal rendering)
Ideal for: A senior iOS engineer who likes fast, scoped, high-agency sprints — the kind of person who'd rather solve real bugs against a real bug list in two weeks than sit in a long onboarding process. Could extend past the initial sprint if there's mutual interest.
Compensation: Paid contract, part-time hourly or fixed-scope for the sprint
