Senior Software Engineer - Mobile (iOS)

About the role

This is a Senior Software Engineer (Mobile, iOS) opportunity with a Series D consumer sleep and recovery technology company, combining hardware, software and AI. It is not healthtech in the provider sense. The app is the main way members control the product and see insights. You’ll build and ship native iOS features, conduct code reviews and optimise app performance, working closely with backend, firmware and ML engineers. The stack is Swift, SwiftUI and Combine. The ideal candidate will have 6+ years shipping high-quality features in native iOS apps, expertise in Swift, modular architecture experience and a degree in computer science or equivalent. App Extensions (Apple Watch, widgets) and consumer health and wellness experience would be advantageous. This is an on-site role in the San Francisco Bay Area, so it sits outside your New York focus. The company describes a high-intensity culture. We're looking for someone curious, pragmatic, and eager to work across the stack with a small senior team. You'll own end-to-end delivery of major features, influence architecture, and mentor engineers.

What you'll do

• Ship customer-facing features on a weekly cadence.
• Partner with design and product on scoping and trade-offs.
• Drive technical quality through review, testing, and docs.
• Mentor one or two engineers on your team.
