We are seeking a highly skilled Machine Learning Engineer with deep expertise in acoustic signal modeling/ Classification modeling to lead the development of advanced detection systems based on audio data.This role requires hands-on experience in training, optimizing, and deploying deep learning models for real-world acoustic environments, with strong production engineering capabilities on Linux systems.

• Role Responsibilities

·       Design and implement end-to-end ML pipelines for acoustic detection

·       Develop and optimize models using time-frequency representations (STFT, Mel spectrograms, etc.)

·       Design robust evaluation frameworks (ROC, PR curves, FAR/FRR, detection latency)

·       Engineer production-ready Python systems running on Linux

·       Build scalable, maintainable inference services and pipelines

·       Optimize models for real-time and edge deployment (e.g., Jetson, ARM-based systems)

·       Collaborate with acoustic experts and system engineers to refine detection performance

• Required Qualifications

·       3+ years of hands-on experience in ML model development using Python

·       Strong experience with PyTorch or TensorFlow

·       Proven experience in audio/acoustic ML (environmental sound classification, event detection, etc.)

·       Solid understanding of Digital Signal Processing (STFT, windowing tradeoffs, time–frequency resolution, filtering, sampling theory)

·       Experience handling imbalanced datasets and rare-event detection

·       Strong experience writing production-ready Python code on Linux systems (process management, concurrency, memory optimization, logging, packaging, deployment)

·       Experience building ML systems that run continuously in real-time environments

·       Proficiency with NumPy, SciPy, librosa, torchaudio, or similar

• Strong Advantage

·       Multi-microphone array processing

·       Real-time inference optimization (ONNX, TensorRT, quantization)

·       Edge deployment experience (Jetson, embedded Linux, ARM)

·       Experience with containerization (Docker) in Linux production environments

·       Background in surveillance, aerospace, or drone-related systems

• What We're Looking For

·       Deep technical ownership

·       Strong debugging skills in real-world noisy systems

·       Research mindset combined with production engineering discipline

·       Ability to bridge experimental ML and reliable operational systems
