Algorithm Engineer

This position covers multiple algorithm areas: speech algorithms, multimodal algorithms, AI algorithms, and hearing-aid algorithms. We do not restrict applicants to specific algorithm project experience. As long as you are interested in algorithm research for audio products and hearing-aid products, you are welcome to apply!

AI Algorithms

Key responsibilities

• Develop technical roadmaps for AI models, conduct model selection and effect optimization, perform model training, fine-tuning, inference and validation, and choose appropriate implementation solutions based on product requirements.
• Build data and training pipelines, participate in establishing data formats, metadata, annotation and version standards, and drive collection, generation, quality assurance, procurement and compliant use of multi-source data.
• Establish unified model evaluation and regression systems, compare third-party, open-source and proprietary models using real device data, and analyze task quality, robustness, latency, stability, resource consumption and usage costs.
• Drive model deployment on cloud and edge devices, complete model conversion, quantization, compression, pruning, distillation and inference acceleration, and optimize solutions based on target device constraints in computing power, memory, power consumption and latency.
• Complete edge deployment using frameworks such as ONNX, TFLite, NCNN, MNN, or perform online inference, auto-scaling, version release and rollback based on GPU, containers and cloud services.
• Collaborate with signal processing and systems teams to optimize end-to-end performance, analyze the impact of data collection, pre/post-processing and runtime environment on model performance, and assist in locating end-to-end issues.
• Use internal AI engineering platforms to manage datasets, training tasks, model versions, validation reports, deployment and runtime logs, ensuring experiments are reproducible and model versions are traceable, releasable and rollbackable.
• Work with product, engineering and testing teams to complete technical research, solution design, feature integration and production acceptance, and address practical issues between experimental results and user experience.
