This role focuses on developing vertical ASR models optimized for high-accuracy transcription in noisy, safety-critical environments, including aviation communications, cockpit interactions, operational dispatch, maintenance coordination, and related specialized audio domains. You will work across the full ML lifecycle - data engineering, model training, evaluation, deployment, and optimization - to deliver production-grade speech intelligence capabilities integrated into ForeFlight and broader aviation platforms. This position is ideal for someone with deep expertise in speech AI, acoustic modeling, large-scale transcription pipelines, and domain adaptation techniques for specialized vocabularies and constrained communication environments., * Design, train, and optimize domain-specific ASR models for aviation and operational communications. * Develop verticalized speech models tuned for specialized terminology, accents, abbreviations, call signs, and noisy radio/audio conditions. * Build and maintain large-scale transcription and labeling pipelines for supervised and semi-supervised learning workflows. * Fine-tune foundation speech models (e.g., Whisper, wav2vec, Conformer, RNN-T, Citrinet, NeMo-based architectures) for aviation-specific use cases. * Improve transcription quality through language model adaptation, pronunciation lexicons, contextual biasing, and decoding optimization. * Develop evaluation frameworks and benchmarking methodologies using WER, CER, domain entity accuracy, latency, and robustness metrics. * Collaborate with product, avionics, data engineering, and platform teams to deploy scalable real-time and batch transcription systems. * Optimize inference pipelines for edge, cloud, and low-latency streaming environments. * Research emerging techniques in speech enhancement, diarization, speaker adaptation, multilingual ASR, and audio foundation models. * Ensure compliance with security, privacy, and operational reliability standards required in aviation environments. ## Related Videos - [Raise your voice!](https://www.wearedevelopers.com/videos/10-raise-your-voice) - [ Evaluating AI models for code comprehension](https://www.wearedevelopers.com/videos/1462-evaluating-ai-models-for-code-comprehension) - [Docker Compose: Rediscovered](https://www.wearedevelopers.com/videos/1978-docker-compose-rediscovered) - [Photonic Computing: Programming a New Class of AI Accelerators (incl.
