# Software Engineer, Product

> Sweep360 · New York, United States · Full-time · Posted 2026-07-06

**Salary:** USD 180,000–220,000

**Workplace:** on_site

**Department:** Engineering

## Description

**TL;DR – We’re building humanity’s defense layer for the AI age and are looking for a Firmware Engineer to build systems that operate in real environments and survive contact with reality.  
**

_If you would have joined Nest before connected devices became commonplace—or Figure AI before humanoids left the lab—to build the firmware that made them trustworthy, 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?

-   One of the first 10 engineers shaping hardware systems pre-Series A.
-   Own firmware that leaves the lab and operates in some of the world’s highest-stakes environments.
-   Work directly with the hardware lead across EE, firmware, and embedded systems.
-   Operate in environments where hardware decisions have immediate consequences.
-   Partner with RF, ML, and product teams to deliver integrated systems.
-   Define the trust boundary between hardware and software.  
    

### What we’re looking for...

-   4–8 years shipping reliable production systems.
-   Polyglot engineer comfortable moving between TypeScript, Python, and systems languages like Rust or Go as the problem demands.
-   Comfortable deploying and integrating with cloud systems like AWS or GCP in production environments.
-   Obsess over software quality, reliability, and maintainability.
-   Built production systems using LLMs, vector databases, and retrieval pipelines.
-   Thrived in an early-stage startup.
-   U.S. Person status required. May involve export-controlled data.  
    

### Bonus if you’ve...

-   Built production web applications used by technical or operational teams.
-   Built iOS applications or worked closely with native mobile teams.
-   Integrated LLMs, vector databases, or graph-based reasoning into production products.
-   Created secure operational dashboards, admin tooling, or internal developer platforms.
-   Worked with IoT, BLE/Wi-Fi, spatial computing, or sensor-driven products.
-   Optimized backend systems and databases under production load.  
    

### 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.
-   Turn customer workflows into production product capabilities using LLMs, graph reasoning, and sensor data.
-   Ensure reliability through testing, automation, and tight feedback loops.
-   Work directly with customers and deployments globally (~10–15% travel).  
    

### How we select...

-   Short application
-   20-minute intro call
-   Technical deep-dive
-   Practical problem discussion
-   References and offer  
    

### Final facts.

Base salary up to $220,000 depending on qualifications, experience, and impact. Total compensation includes equity, premium insurance, 401(k), flexible PTO, and other individual benefits.  
  
You’ll join us on-site at our HQ in New York City with occasional domestic and global deployments.  
**Apply. Build humanity’s defense against machines.**
