Our solutions help freight carriers, brokers, and shippers automate and streamline their operations, reduce costs, and improve efficiency. We are on a mission to drive innovation in the industry by providing cutting-edge SaaS solutions that enable seamless communication and collaboration across the supply chain. DESCRIPTION: Transflo is seeking a Senior AI/ML Engineer to lead the design, development, and continuous advancement of our Intelligent Document Processing (IDP) platform. This is a high-impact AI-first engineering role at the intersection of large language models (LLMs), computer vision, and multimodal machine learning — applied to one of the most document-intensive industries in the world. You will architect and operate AI systems that automatically classify, extract, and interpret millions of freight documents — bills of lading, proof of delivery, rate confirmations, inspection reports, and more — with high accuracy and at production scale. You will work with foundation models, fine-tuned LLMs, and multimodal pipelines, bringing together AWS AI/ML services, modern MLOps practices, and advanced prompt engineering to push the boundaries of what automated document intelligence can do. This role requires someone who thinks in systems: from raw document ingestion through model inference, feedback loops, retraining pipelines, and governed model deployment. AI and ML are not tools you reach for occasionally — they are the core of everything you build. CORE AREAS OF RESPONSIBILITY: AI & LLM System Design • Design and build end-to-end AI systems for intelligent document processing, combining large language models (LLMs), vision-language models (VLMs), and classical ML techniques to solve document classification, entity extraction, and data validation challenges • Architect multimodal AI pipelines that process structured, semi-structured, and unstructured documents containing mixed text, images, tables, handwriting, and complex layouts • Evaluate, select, and deploy foundation models (FMs) via AWS Bedrock, including fine-tuning, retrieval-augmented generation (RAG), and model adaptation strategies appropriate to document intelligence use cases • Develop and continuously refine advanced prompt engineering strategies — including hierarchical prompting, context-aware prompts, visual layout-aware prompts, few-shot and zero-shot techniques, multi-turn dialogue, image-text alignment prompts, and cross-attention optimization — to maximize accuracy and robustness of FM-based extraction pipelines • Stay current on frontier AI research (multimodal transformers, document foundation models, agentic LLM patterns) and translate relevant advancements into production system improvements Machine Learning Engineering & MLOps • Design, train, and deploy scalable ML models using Amazon SageMaker, including experiment management, hyperparameter tuning, distributed training, and endpoint deployment • Own the full ML lifecycle using MLflow on AWS: experiment tracking, model versioning, artifact management, model registry, and promotion workflows from experimentation to production • Build and maintain robust MLOps infrastructure including CI/CD pipelines for model training and deployment, automated model monitoring, drift detection, and triggered retraining workflows • Optimize model inference performance and cost-efficiency using Amazon Elastic Inference, SageMaker inference optimization features, model quantization, batching strategies, and caching patterns • Implement evaluation frameworks and benchmark suites to rigorously measure model accuracy, extraction quality, latency, and regression risk across document types and edge cases Multimodal Document Intelligence • Implement and optimize multimodal ML pipelines for document classification, field extraction, layout understanding, and semantic interpretation across diverse freight and logistics document types • Integrate AWS Textract for OCR, form extraction, and table parsing; integrate Amazon Rekognition for image classification, object detection, and visual content analysis within AI workflows • Apply textual models for image classification and leverage open-source vision-language tools (e.g., LLaVA, PaddleOCR, LayoutLM variants, Donut) to extend and complement AWS-native capabilities • Design prompting and extraction strategies that account for document layout structure: bounding boxes, reading order, multi-column formats, stamps, signatures, and handwritten annotations Serverless AI Pipelines & Platform • Build serverless AI inference and orchestration pipelines using AWS Lambda, API Gateway, and Step Functions, enabling scalable and cost-efficient document processing workflows • Collaborate with data engineers and backend platform teams to ensure clean, reliable data flows between source document ingestion, AI processing layers, and downstream data consumers • Contribute to the design of AI-powered Data as a Service (DaaS) capabilities, enabling structured, AI-extracted document data to be consumed by internal analytics platforms and external API clients • Champion observability and reliability in all AI systems: structured logging, inference latency monitoring, confidence score tracking, human-in-the-loop escalation workflows, and alerting for model degradation Collaboration & Applied Research • Partner with data scientists, cloud engineers, product managers, and business stakeholders to align AI model capabilities with real-world document processing requirements and accuracy targets • Translate ambiguous business requirements into well-defined ML problem formulations, evaluation criteria, and iterative improvement plans • Contribute to internal AI engineering standards, reusable pipeline components, and model governance documentation REQUIRED EXPERIENCE: • 5+ years of professional ML/AI engineering experience, with at least 2 years focused on LLMs, foundation models, or multimodal AI systems in production environments • Extensive hands-on experience with AWS Bedrock for deploying, prompting, and fine-tuning foundation models across multimodal and text-based applications • Deep proficiency with Amazon SageMaker for model training, hyperparameter optimization, hosted endpoint deployment, and pipeline orchestration • Proven MLOps experience with MLflow on AWS: experiment tracking, model versioning, registry workflows, and integration with CI/CD systems • Demonstrated advanced prompt engineering expertise across multiple paradigms: hierarchical prompting, context-aware and layout-aware prompting, few-shot and zero-shot learning, multi-turn dialogue, image-text alignment, and cross-attention prompt optimization • Hands-on experience with AWS Textract and Amazon Rekognition for document extraction, OCR, table detection, and image analysis within automated ML workflows • Experience building serverless AI pipeline architectures using AWS Lambda, API Gateway, and Step Functions • Working knowledge of Amazon Elastic Inference and SageMaker optimization tools for inference cost and latency management • Proficiency with AWS Deep Learning AMIs for rapid environment provisioning and reproducible ML experimentation • Strong Python skills: PyTorch or TensorFlow, Hugging Face Transformers, LangChain or LlamaIndex, and supporting data science libraries • Solid understanding of transformer architectures, attention mechanisms, tokenization, embedding models, and retrieval-augmented generation (RAG) patterns • Experience implementing CI/CD pipelines for ML systems including automated model evaluation gates, deployment promotion workflows, and rollback strategies SKILLS/EXPERIENCE: • Industry experience in document-intensive domains such as transportation, logistics, financial services, healthcare, or legal, where document accuracy and extraction quality have direct operational impact • Familiarity with transportation document types such as bills of lading, proof of delivery, rate confirmations, carrier invoices, inspection reports, or FMCSA compliance documents • Experience with document foundation models or layout-aware vision-language models such as LayoutLM, LayoutLMv3, Donut, PaddleOCR, or LLaVA • Familiarity with human-in-the-loop (HITL) feedback systems and active learning workflows for iterative model improvement using real-world production data • Experience with vector databases (Amazon OpenSearch, Pinecone, Weaviate, or pgvector) and semantic search patterns for document retrieval and RAG pipelines • Knowledge of model governance, responsible AI practices, confidence scoring, and auditability requirements for AI systems operating in regulated or high-stakes environments • Experience working in fully remote, distributed engineering team Apply for this Position Go back to the job list powered by Transflo
