NLP Jobs

My Gazebo hospital-auction simulation runs three TurtleBot3s under ROS 2 Humble on Ubuntu 22.04. The nodes launch without crashing, NLP commands publish correctly, yet nothing appears or moves in RViz. RViz throws its usual “Global Options → Fixed Frame does not exist” warning, so the TF tree clearly is not reaching the visualiser; after that the robots ignore the velocity messages as well. I need someone experienced with ROS 2 Humble, TF2, Gazebo / Ignition, and TurtleBot3 launch stacks to jump in, inspect the running graph, and eliminate the missing-frame problem so the three bots become visible and responsive again. I have all launch files, URDFs, and NLP command source ready to share over a screen-share or repo. You’d trace the TF broadcasts, confirm the map/odo...

Description We are building a network of specialists who help validate and improve the reliability of enterprise AI systems. Our company, , works with organisations deploying AI assistants and knowledge systems powered by large language models and RAG (Retrieval-Augmented Generation). Your role will be to review AI responses, detect hallucinations, validate grounding against source material, and help create evaluation datasets. This is not model development. This role focuses on AI quality assurance and validation. Responsibilities • Review LLM responses for factual accuracy • Identify hallucinations and fabricated references • Verify whether answers are grounded in provided documents • Detect retrieval vs generation failures in RAG systems • Score responses...

I have a set of PDF files from which I need to pull out only certain phrases—no tables, headings, or other content. There are a few distinct phrase types and I want each type to land in its own column in a single Excel worksheet. Speed matters, so I’m leaning toward an AI-assisted Python solution that can rip through multiple PDFs in one go, spot the target phrases with reliable pattern matching or NLP, and then push clean, column-separated data straight into .xlsx. You’re free to choose whichever libraries you prefer—pdfplumber, PyPDF2, Camelot, spaCy, even a lightweight transformer model—so long as the final workflow is reproducible on my end with minimal setup. Deliverables: • Well-commented script (Python preferred) that takes a folder of PDFs as in...

I am expanding my software-engineering agency into the US, Canada, and European markets and I need a confident voice on interview calls who can represent our senior developers. So US, Canada, Australia Citizens are prefered. When a potential client schedules a technical interview—whether the topic is JavaScript micro-services, Python data pipelines, Machine Learning with PyTorch, or the finer points of Software Architecture—you will join the call, introduce yourself on behalf of the engineer, and guide the conversation toward closing the engagement. Because every prospect is different, I am looking for someone already comfortable in the technology sector. Familiarity with Software Architecture is essential; being able to reference image processing, deep-learning or NLP concept...
