Overview
Job Description
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 would have joined Palantir, Nest, or Tesla at the very early start to build an infrastructure from scratch — not just clean datasets — this is that role.
Why Sweep?
As intelligent machines proliferate into every part of the physical world, we humans still lack a defense layer to ensure the systems and devices we rely on remain aligned with us.
We're building that layer today by deploying alongside the world’s highest-stakes teams — Olympic delegations, F1 paddocks, halftime shows, global tours, studio productions, senior government officials, and executive protection units. What we learn there becomes the foundation for a civilization-defining capability.
We’re a small, talent-dense team with high ownership, high velocity, and low ego. We care deeply, move fast, and are here to build something that outlasts us.
Together, we’ll redefine cyber-physical security for the AI age.
What makes this role special?
- You’ll define how the system is used as the first dedicated full stack engineer.
- There’s no existing interface for this category.
- Your work is deployed and tested by real users from day one.
- Operate in high-stake, high-visibility environments you might not talk about, but won’t ever forget.
- Shape product direction and technical roadmap.
- Gain pre-Series A ownership as one of the first 10 engineers.
What we’re looking for
- Polyglot engineer (JS + Python+ Rust/Go preferred) who can quickly pick up new tools when needed.
- Comfortable deploying and integrating with cloud systems (AWS/GCP) in production environments.
- 5+ years shipping production systems where reliability matters.
- Worked with LLMs, vector databases, and prompt pipelines.
- Operates independently, ships fast, and holds a high bar for output.
- U.S. Person status required (may involve export-controlled data).
Bonus if you’ve
- Built iOS applications.
- Tinkered with IoT or spatial computing (BLE/WiFi, AR/VR).
- Obsess over code-quality (SonarQube or similar).
- Built secure operational dashboards or admin workflows.
- Optimized database performance under scale.
What you’ll do
- Own user-facing systems and internal tools.
- Build product systems across web, mobile, and internal tooling.
- Integrate with backend systems and deploy product-facing services.
- Leverage LLMs, graph reasoning, and sensor fusion across production systems.
- Ensure reliability through testing, automation, and tight feedback loops.
- Work directly with elite users globally (~10–15% travel).
How we select
- Short application
- 20-minute intro call
- Technical deep-dive
- Show us something you’ve built that makes you proud
