Principal Engineer – Time-Series & Sensor Reasoning Models (Lorenz Labs)

tems that can reason about the physical world. We are building the next generation of models that go beyond language and vision, into time, signals, and embodied experience. Our long-term ambition is the realization of an Artificial Engineer: an AI capable of understanding, simulating, and designing electro-physical systems with human-like intuition—complemented by the development of highly optimized embedded models for Edge AI.**About the Role** We are seeking a Principal Engineer in Time-Series & Sensor Foundation Models to advance AI engineering at the intersection of sensing, signal intelligence, and large-scale temporal modeling. This role will develop architectures that unify multimodal sensor data—including audio, motion, photonic, and physiological signals—into a coherent foundation for context-aware reasoning across time. Your work will contribute directly to ADI’s PhysGPT suite of physically-intelligent reasoning models.**Key Responsibilities** Investigate modern foundation alignment techniques, including DPO (Direct Preference Optimization) and RLAIF (Reinforcement Learning from AI Feedback) for physical and sensory reasoning tasks. **Must Have Skills** Experience in context-aware and multimodal reasoning—especially involving audio perception, biosignals, or environmental context.Proficiency in representation learning, causal inference, and motif discovery in high-dimensional temporal data.Familiarity with benchmarking, evaluation, and robustness testing of foundation and fine-tuned models. Ability to collaborate across disciplines—ML, hardware, and embedded systems—and translate research into deployable physical intelligence systems. **Preferred Education and Experience** 10+ years of combined research and industrial experience in ML, signal processing, or embedded sensing. * This position qualifies for a discretionary performance-based bonus which is based on personal and company factors.* This position includes medical, vision and dental coverage, 401k, paid vacation, **holidays, and sick time**, and other benefits.Actual wage offered may vary depending on work location, experience, education, training, external market data, internal pay equity, or other bona fide factors. #J-18808-Ljbffr
