iOS Developer

At Arpalus, recently acquired by Instacart, we build AI-powered computer vision and AR technology that turns a phone camera into a precise sensing tool - real-time object detection, scanning, and spatial understanding shipped as a mobile product. Our tech runs on real devices, in real environments, under messy real-world conditions.

We're a small, fast-moving team and we're looking for an iOS Developer who already works that way too.

You'll join our iOS development team and help craft best-in-class mobile experiences via our mobile SDK and iOS app and help us solve genuinely hard problems in computer vision and AR. You'll work hands-on and leverage GenAI tools to speed up development cycles and

In this role, you’ll partner closely with product, design, data science and backend to deliver new and unique features. You’ll help shape the iOS strategy for the team, influence technical direction across codebases, and ship high-quality, observable software at scale.

We value clear communication, practical problem solving, and ownership. If you thrive in a fast-paced, evolving environment where you can roll up your sleeves, make thoughtful tradeoffs, and see your work move key metrics, you’ll feel right at home here.

About the Job

Own and evolve our native iOS SDK (Swift) for AR-based shelf scanning.

Work on the core product recognition engine that powers real-time retail analytics -from ARKit scene understanding to CoreML inference to App Store distribution.

Build and optimize computer vision pipelines using Vision framework and CoreML

Implement AR experiences with ARKit for real-time shelf scanning

Package and distribute the SDK as XCFramework with proper signing and versioning

Manage the full App Store submission and TestFlight distribution process

Design clean, well-documented public APIs for SDK consumers

Profile and optimize performance for real-time inference on device

Deliver features end to end: technical design and clean architecture, implementation, phased rollout, observability to confirm impact, and on-call/incident response when needed.
