Comfort with MLOps: deploying models into production, monitoring drift, ensuring cost-efficiency. Nice-to-Haves: Familiarity with MT evaluation: BLEU, COMET, MQM, or newer LLM-based scoring methods. Applied work in speech and multimodal ML: transcription (STT), speech isolation, diarization, TTS, dubbing. Ability to design scalable evaluation pipelines: run automated evaluations at segment/file/content level across multiple languages. Experience with human-in-the-loop evaluation workflows (sampling, quality control). Knowledge of cultural/linguistic nuances in translation (since QUAIL will measure “fit for purpose” quality).
