TL;DR — We're building humanity's defense layer for the AI age and are looking for a high-agency iOS Engineer early in their career who wants real ownership, real constraints, and real impact from day one.

If you want to build systems that leave the simulator and survive reality—this is that role.

Why Sweep?

As intelligent machines proliferate into every part of the physical world, humans still lack a defense layer to ensure the systems and devices we rely on remain aligned with us.

Sweep is building that layer today. Our technology is already deployed alongside some of the world's highest-stakes teams—from decision-makers and elite market-movers to frontline journalists, chart-topping artists, record-breaking athletes, and history-bending scientists. What we learn there becomes the foundation for a civilization-defining capability.

We're a small, talent-dense team with a bias for high ownership, high velocity, and low ego. We care deeply, move fast, and are here to build something that outlives us.

Together, we'll redefine cyber-physical security for the AI age.

What makes this role special?

• Ship iOS product early and often—no long ramp, no busywork.
• Work on a mobile system used in high-stakes environments where precision, latency, and reliability matter.
• Learn directly from senior engineers, field operators, and real users.
• Operate with Bletchley-Park intensity—rapid feedback, real consequences, and deployments you might never discuss, but will never forget.
• Build judgment by seeing what breaks and fixing it.
• Gain pre-Series A ownership as an early contributor.

What we're looking for

• Strong foundation in Swift and iOS development.
• Experience shipping iOS apps via internships, personal projects, open-source work, or startups.
• Solid understanding of Apple's Human Interface Guidelines and platform fundamentals.
• Comfort operating under ambiguity and learning fast.
• Clear communication and ownership mindset—we expect responsibility from day one.
• Rigor and attention to detail.
• Startup urgency: independent, accountable, relentless execution.
• U.S. Person status required (may involve export-controlled data).

Bonus if you've

• Prototyped interactions in Figma and translated them cleanly into code.
• Worked with ARKit, Metal, Combine, Accessibility, or spatial UI.
• Optimized performance under real constraints.
• Built or shipped something outside of class requirements.
• Thrived in a small or early-stage team environment.
