Software Engineer, Product

Why Sweep

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.

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

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)

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
