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, but never forget.
• 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.
