Senior AI Engineer, Time-Series Signal Processing

BrightAI is a high-growth Physical AI company transforming how businesses interact with the physical world through intelligent automation. Our platform processes visual, spatial, and temporal data from billions of real-world events—captured through edge devices, mobile sensors, and large-scale cloud infrastructure—to deliver intelligent, real-time decisions.

We are now hiring a Senior AI Engineer – Time-Series Signal Processing to lead the development of AI/ML solutions built on high-frequency multi-modal sensor data. This is a critical role focused on modeling and understanding time-series signals coming from IoT devices equipped with various sensors (IMU, acoustic, pressure, temperature, etc.) that drive intelligent automation across physical infrastructure systems.

You'll work on building cutting-edge real-time AI models that process noisy, high-throughput data streams and extract meaningful insights for real-world decision-making—at both the edge and cloud scale.

• Design and implement real-time signal processing and ML pipelines for multi-modal time-series data such as those acquired from IMUs, microphones, pressure or force sensors, ultrasonic transducers, and similar sensor sources.
• Develop and deploy ML models for time-series classification, prediction, anomaly detection, activity recognition, condition monitoring and pattern analysis.
• Lead research and implementation of RNN-based architectures (especially LSTMs and their variants) as well as temporal transformer models as needed.
• Build and tune classical and tree-based ML models (XGBoost, LightGBM, Random Forests, and other gradient-boosted ensembles) for time-series tasks, including feature engineering and model interpretability (e.g., SHAP).
• Work with SCADA systems and industrial telemetry data—ingesting and modeling high-frequency, multi-channel operational data streams from physical assets.
• Collaborate with hardware, embedded, and product teams to integrate models into edge devices and IoT platforms.
• Drive experimentation and optimization of signal-processing techniques (e.g., filtering, feature extraction, event detection) to enhance model input quality.
• Design and maintain scalable workflows for ingesting, labeling, training, and evaluating multi-channel time-series datasets.
• Stay current with advances in time-series modeling, signal processing, and real-time inference, and incorporate them into product roadmaps.
• Ensure model robustness, performance, and reliability in production environments, including edge deployments.

• Degree in Electrical Engineering, Computer Science, or a related field, with a strong focus on signal processing, time-series analysis, and machine learning.
• Strong academic or industry track record in time-series modeling, signal processing, or real-time AI systems.

• 5+ years of experience developing signal processing and ML solutions for time-series sensor data. Track record of bringing at least one ML solution to market.
• Deep understanding of digital signal processing (DSP) methods: filtering, sampling, windowing, FFT, feature extraction, etc.
• Hands‑on experience with RNNs (especially LSTMs/GRUs) and/or temporal convolutional networks for time-series modeling.
• Proficiency with tree-based and gradient-boosting models (XGBoost, LightGBM, Random Forests) applied to time-series and sensor data, including hyperparameter tuning and explainability.
• Experience working with SCADA systems and industrial telemetry data (high-frequency sensor feeds, time‑stamped operational data, multi‑channel ingestion from physical assets).
• Proven experience with time-series data from physical sensors such as IMUs, microphones, vibration or pressure sensors.
• Strong coding skills in Python and fluency with ML/DL frameworks (e.g., PyTorch, Tensor Flow).
• Experience in optimizing and deploying models in real-time or near‑real-time environments, including edge devices or resource‑constrained embedded systems.
• Fluency with best practices in data labeling, augmentation, and evaluation for time-series tasks.
• Excellent problem-solving and collaboration skills with the ability to work across teams.
