Scrollmark
Staff iOS Engineer (San Francisco)
Scrollmark, San Francisco, California, United States, 94199
Join us in a high-impact role where you'll craft a world-class iOS experience that powers AI social media workflows for creators.
At Scrollmark, we're building SocialGPT (https://www.gpt.social/), your copilot for social media content creation-helping creators and brands plan, create, and grow with confidence.
We've raised $8M in seed funding
from top-tier investors including Mayfield and Jackson Square Ventures. As an early-stage startup, we're looking for a senior iOS engineer who obsesses over performance, polish, and creator workflows. You'll work directly with our CTO and partner across product, design, and backend-owning features end-to-end, from prototype to App Store release. You'll also
set the roadmap and mentor/hire
as we scale.
We've raised
$8M
in seed funding from top-tier investors including Mayfield, Jackson Square Ventures, Lemniscap, Shakti, and Aperiam. As an early-stage startup, we're seeking team members who combine technical expertise with a self-starter attitude. Reporting directly to our CTO and collaborating closely with other engineering leaders, you'll have the autonomy to drive projects that make a lasting impact.
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. What We're Looking For
5+ Years Shipping iOS Apps:
You've built and maintained production iOS apps with meaningful scale and ratings, and you can point to features you owned end-to-end Expertise in Swift/SwiftUI (and UIKit where pragmatic):
Strong command of async/await, Combine (or equivalents), 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.
