Scrollmark – Staff iOS Engineer (San Francisco)
Overview : Join an early‑stage startup building SocialGPT (https://www.gpt.social/), a copilot for social media content creation. You’ll craft a world‑class iOS experience that powers AI social media workflows for creators. We’ve raised $8 M in seed funding from top‑tier investors including Mayfield, Jackson Square Ventures, Lemniscap, Shakti, and Aperiam.
What You’ll Do
Build the Next‑Generation Creator App (iOS): Design and ship a fast, intuitive, native iOS app (Swift/SwiftUI, UIKit where it fits) that makes content planning, creation, and publishing feel effortless.
Design and Integrate AI Workflows: Build frontend flows to present insights and suggestions generated by SocialGPT in the most impactful way.
Performance & Usability at 60fps: Own app responsiveness, animations/haptics, offline‑first UX, background uploads, and startup time using Instruments, signposts, and proactive profiling.
Collaborate & Iterate: Prototype quickly with design and product, run user studies with creators, and refine based on in‑app analytics, crash‑free rate, and p99 UI latency.
Scale & Ship Reliably: Set up feature flags, TestFlight cohorts, release notes, and crash/trace monitoring.
Strategize & Lead: Contribute to roadmap and design system; establish mobile best practices, code standards, and testing (unit/snapshot/UITests); mentor teammates as we grow.
Qualifications
5+ years shipping iOS apps with meaningful scale and ratings; you can point to features you owned end‑to‑end.
Expertise in Swift/SwiftUI (and UIKit where pragmatic): strong command of async/await, Combine, navigation patterns, state management, and accessibility.
Product & System Design: translate creator needs into elegant flows; design scalable architectures (modularization, dependency injection, background tasks, data sync, caching).
Media & Performance Chops: hands‑on with AVFoundation/PhotoKit, background processing, offline caching, networking, and rigorous performance tooling (Instruments, MetricsKit).
Platform Integrations & Quality: experience with notifications, widgets, deep links, share extensions, authentication, analytics/experimentation, and App Store submission guidelines.
Self‑Starter, Creator‑Obsessed: you thrive in ambiguity, ship with craft, and care deeply about the details that make creators faster and more confident.
Nice‑to‑Haves
Core ML (on‑device assist features)
Design systems
Android or cross‑platform awareness (KMP/Flutter/RN)
Privacy/security best practices for media apps
