About Firesale

Firesale is an AI-powered resale marketplace built for people with too much stuff and zero time. Sellers record a 2-second video, and our AI instantly generates the title, photos, price, and listing—no typing, no hassle. It's the fastest way to turn clutter into cash, combining yard-sale simplicity with modern tech, automatic price drops, and local pickup or delivery. Firesale makes selling feel effortless and buying feel like a treasure hunt.

We're venture-backed, launching our first market now, and scaling aggressively. You'll be joining the team at the earliest stage, alongside startup veterans including two of the early team members at Uber. This is a rare opportunity to help build the next breakout marketplace brand from the ground up.

About the role

We're looking for a world-class Lead
iOS Mobile Developer
to own the architecture, velocity, and polish of our iOS app. You'll lead development from the ground up—shipping fast, iterating daily, and building products that feel magical. This is not a "maintenance" role. This is a "build what doesn't exist yet" role.

You'll work closely with the founder, design, backend, and AI teams to ship features that combine AI + video + commerce at a speed that feels unfair to competitors. You'll guide technical decisions, elevate code quality, and ensure the app remains lightning-fast, stable, beautiful, and scalable.

If you love owning the entire iOS stack, obsess over UX details, and crave building category-defining mobile products, you'll thrive here.

What you'll do

Lead iOS development across architecture, frameworks, performance, and UI polish.

Own the codebase: structure, patterns, modularization, CI/CD, testing, and release management.

Build and iterate on complex features, including:

• AI-powered video workflows (recording, compression, uploads)
• Real-time search/browse interfaces
• Marketplace flows (checkout, Apple Pay, offers, chat)
• Location-based experiences
• Live streaming
• Push notifications & in-app messaging

Integrate with backend REST APIs, have experience with WebSockets and SSE

Stripe/Apple Pay, AppsFlyer, Analytics (Mixpanel, GA), and user auth

Manage app performance, crash-freeness, battery usage, memory, and smooth 60fps interactions.

Collaborate tightly with design to ship pixel-perfect UI and native-feeling interactions.

Mentor future iOS hires, code review, and raise the bar for engineering standards.

Move fast. Ship fast. Improve constantly.

What You Bring

• 5+ years of experience building and shipping Swift iOS apps end-to-end.
• Expertise in SwiftUI, UIKit, AI, ML, Camera, Combine, async/await, concurrency, and modern Apple frameworks.
• Strong experience with video, camera frameworks, image processing, or real-time uploads.
• Experience integrating
