Software Engineer, Machine Learning (Systems)

If you would have joined early Tesla to make Autopilot work in the real world and improve across the fleet — 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?

• First dedicated ML systems hire
• You're the difference between a system that exists and one that works
• Make the system reliable under pressure — data, pipelines, and decision logic
• Take outputs from sensing systems and turn them into consistent, trusted decisions
• Define how inference works when inputs are incomplete, noisy, or conflicting
• Your work is used in high-stakes environments where outputs must be trusted
• Gain pre-Series A ownership as one of the first 10 engineers

• 5-10 years building and operating production systems
• Strong system design across APIs, pipelines, and data storage
• Deployed ML / LLM systems in production and improved them via feedback loops
• Strong Python, plus Go/TypeScript (or similar)
• Comfortable working across device and cloud environments
• Able to debug production systems quickly and decisively
• Communicates clearly and operates independently.
• U.S. Person status required (may involve export-controlled data)

• Built RF / BLE classification systems and models from zero
• Handled streaming systems (Kafka, pub/sub)
• Created LLM pipelines (prompting, retrieval, evaluation)
• Designed for adversarial or security environments
• Built systems that run on-device as well as in the cloud
• Thrived in early-stage startup environment

• Own system behavior and data pipelines
• Design ingestion → reasoning → decision systems
• Improve the decision layer for consistency and reliability
• Close the loop from deployments → system learning
• Ensure system reliability across device, cloud, and partial connectivity
• Partner with RF / hardware / field teams to deliver for elite users globally (:10-15% travel)

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

Base salary up to $240,000, 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.
