Overview
Job Description
TL;DR — We’re building humanity’s defense layer for the AI age and are looking for an exceptional ML engineer to stabilize the system that turns raw signal into decisions — across device, cloud, and offline environments.
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.
What we’re looking for...
- 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).
Bonus if you’ve...
- 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.
What you’ll do...
- 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).
How we select...
- Short application
- 20-minute intro call
- Technical deep-dive
- Practical problem discussion
- References and offer
