Full Job Description
The Role and Your Impact:

We need a Senior Machine Learning Engineer to lead the perception stack for Archimedes - detection, tracking, classification, and sensor fusion across the targeting chain. You're the seasoned engineer who's shipped perception in something that had to work outside a benchmark. You'll partner directly with our CTO and the robotics software team, and own perception as a domain.

What You'll Own:
  • Perception architecture across detection, tracking, classification, and sensor fusion
  • ML model development, training pipelines, and on-device deployment
  • Multi-sensor fusion across EO/IR and other sensors as relevant to the targeting chain
  • Real-time performance optimization on embedded targets
  • Mentorship of perception engineers as the team grows
  • Direct partnership with controls, robotics SWE, and hardware on what's actually achievable

What We're Looking For:
  • 5+ years building and shipping perception systems on real hardware
  • Strong Python and C++ with deep ML engineering experience
  • Computer vision, tracking, and detection in real-time, real-world conditions
  • On-device deployment experience using TensorRT, ONNX, or equivalent
  • Track record optimizing perception for embedded compute and latency budgets

Where you probably come from: Perception roles at defense companies, autonomy, perception-heavy robotics, or aerospace programs that put perception in front of real targets.

We want to talk if: You've shipped a perception system that ran on real hardware against real targets. You know the gap between paper SOTA and what survives field conditions.

Not a fit if: Your background is research only without deployment, you're a new grad (we'll have a junior role later), or your CV experience is offline batch processing only.

Nice to Haves:
  • Counter-UAS or aerial target tracking experience
  • Radar or RF perception
  • Classified program experience
  • Sensor fusion in adversarial or denied environments

Education:
  • BS, MS, or PhD in CS, EE, Robotics, or equivalent. Track record matters more than degree.

How You Operate:
  • Extreme bias for action. You ship working perception on real hardware, not slideware
  • You debug from first principles, not intuition alone
  • Comfortable with ambiguity and fast iteration in a startup environment
  • Clear communicator across software, hardware, and operator-facing surfaces
  • Self directed. You identify what needs to happen next and do it without being told

How We Work:

Core hours are Monday through Friday, 9 to 6. When we're sprinting toward a demo or field test, the team ramps up - nights, weekends, whatever it takes to ship. When the sprint lands, we ramp down. We don't manufacture intensity for show.

Benefits:
  • Competitive salary + equity
  • United Health Care medical, dental, and vision coverage
  • Flexible 18 days PTO + 5 sick days
  • Travel to field test events and range days
  • Covered daily lunches and office snacks + drinks
  • E-bike / scooter stipend ( Up to $500)
  • Direct access to leadership and real ownership over your work
