**Salary:** USD 160,000–220,000

**Workplace:** on_site

**Department:** Engineering

## 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
-   References and offer

###   
Final facts.
