Job Description
主要职责
1. 模型能力诊断与训练需求挖掘
- 建立并持续维护模型能力评估矩阵(Capability Matrix),覆盖多轮对话核心维度:指令遵循、上下文一致性、Function Call 参数化与触发、知识检索与引用、语言切换、角色稳定性、安全合规等。
- 基于线上 badcase、离线 benchmark、A/B 评测与业务反馈,开展系统性归因分析(Root Cause Analysis),区分模型能力缺陷、数据分布缺口、Prompt/工具链设计问题及场景定义偏差。
- 将诊断结论沉淀为结构化训练需求(Training Demand Spec):明确问题定义、影响范围、严重等级、预期收益及优先级,纳入版本级需求 backlog。
2. 训练需求假设构建与实验验证
- 对每一条潜在训练需求,构建可检验假设(Hypothesis):明确「若补充某类数据 / 能力,模型在何种场景、何种指标上应产生可观测改善」。
- 独立设计并执行需求真实性验证实验,在投入大规模标注与训练资源前完成可行性闸门(Feasibility Gate),典型手段包括:
- Prompt / 上下文消融实验:验证问题是否可通过工程侧调整缓解,而非必须训练解决;
- Few-shot / In-context 探测:用小样本快速验证模型是否具备潜在能力、仅缺数据激活;
- 对比评测(Side-by-side / A-B):量化当前版本与对照策略的差异,确认改进空间;
- 反事实样本构造(Counterfactual Probing):检验模型在关键变量变化下的行为稳定性。
- 输出标准化实验报告:含实验设计、对照组设置、变量控制、结论判定(Train / Prompt-fix / Reject)及后续行动建议,为算法与标注团队提供决策依据。
- 对高优先级需求组织小规模 PoC 验证(Proof of Concept),跟踪实验结论与线上放量结果的一致性,持续校准需求判断准确率。
3. Feature 发现与数据需求规格化
- 从业务场景、人机交互形态及竞品能力中,识别并定义自研模型智能交互新 Feature,输出 Feature Spec(能力边界、触发条件、交互范式、失败模式)。
- 将通过实验验证的训练需求,翻译为可交付的数据需求文档(Data Requirement Document)
- 参与 Roadmap 规划与版本对齐,确保 Feature 定义、benchmark 建设、训练集交付与模型发版节奏一致。
Requirements
任职要求
必备
- 本科及以上学历,CET-6 及以上;语言学、心理学、人机交互、计算机、数据科学等相关专业或同等经验。
- 2 年以上 NLP / 大模型 / 对话系统相关经验;有多轮对话、Function Call、RAG 或业务机器人落地经验者优先。
- 具备假设驱动的问题分析能力:能从 badcase 中抽象可验证假设,设计对照实验并给出 Train / Prompt-fix / Reject 的明确结论。
- 能独立撰写实验验证报告、训练需求规格书(Training Demand Spec)、数据需求文档(DRD),逻辑严谨、结论可复现。
- 责任心强,抗压能力强,适应创业公司标准迭代快、跨团队沟通多的节奏。
