Senior Plasma Control Engineer

Team: Electrical and Control Systems Engineering

Location: Kearny, NJ

Commitment: Full-time

Workplace Type: onsite

Key Responsibility Areas:

Plasma control algorithms and real-time software:
• Develop, test, and iterate plasma control algorithms for Eos PCS, including multi-rate feedback, supervisory logic, and constraint handling.
• Build AI/ML assisted control modules, such as learning-augmented MPC, reinforcement learning in simulation, physics-based models augmented with data-driven corrections, and adaptive control and auto-tuning across operating conditions
• Develop and deploy real-time state estimation and multi-diagnostic data fusion to produce control-grade plasma state, including robust profile reconstruction and regime indicators suitable for closed-loop operation.
• Develop anomaly detection and early-warning indicators across plasma and plant signals, with clear thresholds and graded mitigation actions.
• Partner with plasma physicists to translate physics goals into control objectives, observables, constraints, and validation tests.
Digital twins and modeling:
• Design and maintain digital twin models for plasma control loops and coupled plant subsystems, enabling simulation, optimization, and controller development and validation.
• Build model validation workflows, including post-shot reconstruction, scenario sweeps, sensitivity studies, and uncertainty-aware comparisons against experimental data
Data and integration:
• Build and maintain data pipelines for time-series control and diagnostic data, including labeling, archiving, and training and inference workflows.
• Integrate algorithms into the control stack in collaboration with EECS, ensuring compatibility with real-time constraints and low-latency inference where needed.
• Maintain high software quality: version control, test coverage, reproducible environments, and operational readiness documentation.
