Responsibilities

Design and iterate the multimodal document parsing pipeline: layout / structural modeling, semantic extraction, cross‑modal alignment, structural reconstruction
Build and optimize a multi‑agent collaboration mechanism: task splitting, parallel / sequential scheduling, peer review, iterative quality improvement loops
Define model selection / composition / routing strategies (dynamic dispatch by document type, structural patterns, quality signals)
Plan and execute model fine‑tuning, domain adaptation, continual learning, active learning, and data feedback loops
Establish end‑to‑end metrics: extraction accuracy, structural consistency, agent collaboration effectiveness, latency, stability, and cost
Build quality assurance and risk controls: drift & anomaly monitoring, confidence estimation, fallback strategies, alignment / compliance checks
Drive mapping and consistency between agent / model outputs and business knowledge field standards

Required

Education: Master's degree or above in a quantitative or technical field (Statistics, Computer Science, Mathematics, Data Science, etc.)
Experience: 5+ years of hands‑on machine learning / data science experience. Proven delivery experience in multimodal (vision + text) or complex document understanding. Practical cases of orchestrating agents (or modular processing logic) in production workflows
Capabilities: Solid foundation in machine learning / deep learning fundamentals, multimodal representations, and cross‑modal alignment concepts. Deep understanding of core principles and common algorithms for multimodal large models: cross‑modal attention & representation alignment, vision/text embedding fusion, hierarchical & layout structure modeling, instruction & contrastive paradigms, long‑context and retrieval‑augmented mechanisms, evaluation and failure mode dissection. Familiar with classic image and signal processing methods: edge & contour detection, filtering & denoising, morphological operations, segmentation & keypoint feature extraction, frequency / time‑frequency analysis, image enhancement & quality assessment; understands trade‑offs and complementarity with deep features. Knowledge of multi‑agent collaboration patterns: role assignment, task routing, feedback loops, redundancy & cross‑checks. Strong in statistical analysis & experimental design: hypothesis testing, factorial design, power analysis, A/B and multivariate evaluation. Able to decompose complex problems and build metric‑driven optimization paths. Rigorous in data quality & error analysis; rapid bottleneck identification. Ability to translate research pseudo‑code into maintainable, testable Python modules with benchmarking & regression harnesses

Preferred

Designed customization / fine‑tuning of multimodal foundation models, representation learning, or structural understanding subsystems
Built an agent orchestration platform: task decomposition, iterative self‑checks, consensus or voting mechanisms
Experience solving robustness & generalization challenges in large‑scale long documents / heterogeneous layouts
Demonstrated results in cost optimization (model pruning, parameter‑efficient tuning, inference acceleration) or adaptive load scheduling
Publications / patents or open‑source contributions
Demonstrated Python systems optimization (e.g., custom Cython / CUDA kernels, vectorization replacing Python loops, latency reductions in inference pipelines)
