iOS Engineer

Location: Fully remote. We’re prioritizing candidates with solid overlap with US working hours (South America ideal).

We build a camera-heavy iOS app that scans real spaces and turns them into CAD deliverables. It mixes ARKit + sensors + internal CV libraries with regular functionality like checkout and subscriptions. We’re hiring a senior engineer to raise quality and improve system design - not just ship more features.

Responsibilities

• Deliver product features end-to-end, with a bias toward shipping.
• Improve app state / data flow and app ↔ backend contracts.
• Drive practical automated testing adoption: prioritize networking/data/state layers, and push toward “no new code without tests” over time.
• Improve reliability and clarity across complex user journeys (i.e. purchase/subscription flows and feature-flag combinations).
• Debug hard problems: crashes, concurrency/threading, performance, memory/lifecycle.
• Communicate clearly in English (written and spoken) and collaborate well across roles.

Qualifications (Must-haves)

• You’ve shipped and maintained real production iOS apps.
• Strong Swift + iOS fundamentals: networking, persistence, lifecycle, performance.
• Comfortable with Swift Concurrency (async/await) and can reason about threading bugs (GCD familiarity helps).
• UIKit + SwiftUI experience (we’re ~60% SwiftUI / ~40% UIKit), Core Data experience.
• Strong grasp of distributed systems realities from a client perspective: retries, idempotency, eventual consistency, and degraded-mode UX.
• Testing discipline: XCTest, architectural testability; UI tests/snapshot tests are a plus.

Nice-to-haves

• ARKit / camera-heavy apps / sensor-heavy work.
• Designed sync / high-volume networking features with explicit server-load considerations (request budgets, batching/pagination, concurrency limits, retries/backoff).
• Habit of writing mobile designs that include app↔backend contract details: failure modes, rate limiting, and how we validate performance (metrics/tests).
• Experience collaborating with backend to evolve APIs for efficiency (batch endpoints, server-side filtering etc), instead of scaling by “more client requests.”
• WKWebView + JS/native boundary debugging.

How we work

• Remote-first, cross-functional team (iOS, Backend, QA, CV, Product/Design).
• AI-assisted coding is encouraged; good judgment is required.
• Release cadence aims for ~2-week TestFlight cycles (occasionally changes).
