Sr. AI Engineer, Time-Series Signal Processing

Bright.AI 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.

Responsibilities

  • 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.

  • 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.

Educational Background

  • M.S. or Ph.D. 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.

Required Skills & Expertise

  • 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.

  • 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, TensorFlow, Keras).

  • 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.

  • Strong communication skills with the ability to convey findings and recommendations to internal and external stakeholders.

Bonus Qualifications

  • Experience building end-to-end AI systems for structural health monitoring, condition monitoring, anomaly detection, activity recognition, or motion tracking.

  • Proficiency in embedded software or deploying models to constrained environments (e.g., using TFLite, ONNX, or custom firmware).

  • Familiarity with containerized workflows and Linux-based development environments.

  • Experience with Agile workflows and tools such as JIRA, Git, and CI/CD pipelines.

  • Prior work in startup or high-pace teams with experience in building real-time systems from the ground up.
