Job Description

算法工程师
合肥
社招
全职
数字技术 - 算法
硕士及以上
3-5 年
职位描述
1、模型转换与适配
将主流训练框架的AI模型转换为国产芯片NPU可执行的指令集模型,解决算子不兼容、精度异常等问题。
针对制造场景典型任务(目标检测、分割、分类、异常检测等),维护标准化的模型导入工作流。
2、算子开发与优化
分析国产芯片编译器的能力边界,对缺失或性能低下的自定义算子,使用底层编程语言(如C/C++、汇编或特定DSL)进行补充实现。
优化算子在芯片上的内存访问模式、计算流水线,提升NPU利用率。
3、量化与精度调优
执行INT8、INT4或混合精度量化,设计合理的校准集,将模型从FP32压缩至低比特,同时控制精度损失。
开发精度分析工具,定位量化误差较大的层,通过敏感度分析调整量化策略(逐层/逐通道量化、跳过敏感层等)。
4、部署集成与验证
将优化后的推理引擎封装为C++/Python API,供嵌入式应用工程师调用。
配合测试团队建立模型精度回归测试集,确保每次固件升级后推理结果的确定性。
5、现场支持与模型迭代
跟随产品到制造现场,针对实际生产数据进行模型微调与热更新。
职位要求
学历经验:
1、硕士及以上,计算机、人工智能、电子工程等相关专业;3年以上AI部署或AI编译器相关经验。
技术能力:
1、精通Python/C++,熟悉Linux开发环境。
2、深刻理解深度学习模型结构(CNN/Transformer/RNN),熟练使用ONNX、TensorRT、OpenVINO或至少一种NPU工具链。
3、有实际量化部署经验(INT8/INT4),熟悉量化感知训练(QAT)或训练后量化(PTQ)流程。
4、了解常见算子实现及其硬件亲和性优化技巧。
5、熟悉工业视觉缺陷检测、目标检测等场景模型。
6、具备汇编级优化或DSP编程经验。
