Overview
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.
