Job description
Base pay range
$160,000.00/yr - $220,000.00/yr
Skip this job application if you're looking for an easy calling. Read on if you're a hacker-minded iOS engineer who ships weekly, owns problems end-to-end, and performs best in uncharted waters.
Humanity needs a defense layer against increasingly intelligent machines around us. Without it, the systems and devices we rely on can—and will—turn against us. Join Sweep to build that layer and safeguard the freedoms that let people live, work, travel, create, and operate in a rapidly shifting world.
As our iOS Engineer , you'll build and deploy systems that already protect some of the world's highest-stakes teams — from decision-makers to elite market-movers and frontline journalists, to chart-topping artists, record-breaking athletes, and history-bending scientists. Together, we'll redefine cyber-physical security for the AI age.
Why You Should Join
Mission & Impact - Operate with the intensity of Bletchley Park—high stakes, rapid tempo, and zero room for failure. Your firmware will defend people in real-world environments you may never discuss.
Innovation Ground-Zero - Push the frontier of embedded systems, RF sensing, spatial intelligence, IoT hardware, and on-device AI. You'll invent net-new capabilities, not just iterate.
Founding Ownership - Join the first ten engineers. Shape culture, engineering standards, architecture, and the hardware foundations that keep humans in control of autonomous machines.
What You’ll Do
Build mission-critical, high-performance iOS systems using Swift, ARKit, UIKit, and SwiftUI.
Develop scalable, maintainable solutions leveraging robust design patterns (MVC, MVVM, VIPER).
Integrate advanced sensors, location-based services, and AI for real-time threat detection and defense.
Own the iOS user experience end-to-end — from rough concepts and rapid prototypes to polished interfaces and fluid animations.
Implement rigorous testing (XCTest), automation, and continuous deployment pipelines.
Optimize relentlessly for speed, reliability, and exceptional user experience.
Directly engage elite users—expect about 10% global travel.
Must-Have
Mastery in Swift and Objective-C; deep understanding of Human Interface Guidelines and performance optimization.
5+ years shipping robust, production-grade iOS applications.
Startup urgency: Independent, accountable, relentless execution.
U.S. Person status required (may involve export-controlled data).
Nice-to-Have
Working ability with Figma (prototyping interactions, not full-time design).
Experience with ARKit, Metal shading, Combine, Accessibility and spatial computing technologies.
Proven record optimizing iOS performance under demanding conditions.
Code-quality obsession (SonarQube or similar).
Localization/multi-language support for global deployments.
Compensation
Base salary for this position is up to $190,000 annually, depending on your qualifications, experience, and impact. Total compensation also includes equity, premium insurance, and individual benefits.
Why Sweep?
Sweep selects for mission, impact, ownership. Face-to-face collaboration is how we operate, thrive, and deliver. You'll join us on-site at our NYC HQ or Hybrid in DC, London/Cambridge, UK. Selection Process: Initial 20‑min intro → technical deep‑dive → team exercise → references → offer. Additional questions? Just ask.
