Sweep360

Build and deploy mission-critical full-stack systems with secure cloud infrastructure, integrating advanced AI technologies. | Requires 5+ years of experience in scalable system development, cloud deployment, and familiarity with AI/ML integrations, which are not fully reflected in your experience. | TL;DR — We’re building humanity’s defense layer for the AI age and are looking for a hacker-minded Full Stack Engineer to ship from day one and own problems end-to-end. If you want to invent new categories, not just improve existing ones—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 tech 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? Gain pre-Series A ownership as one of the first 10 engineers defining architecture, standards, and culture. Build software that leaves the lab and survives contact with reality. Influence core product direction and technical roadmap from day one. Operate with Bletchley-Park intensity—rapid feedback, real consequences, and ship prod in places you might never discuss, but will never forget. Partner with elite teams confronting never-seen-before cyber risks. What we’re looking for Polyglot developer (JS, Python, Rust/Go a plus) who rapidly picks up new languages.
