Job description

Nexxa is building the best AI systems for heavy industries — enabling machines, systems and operations to think, decide and act autonomously across manufacturing, large-scale infrastructure, logistics and legacy environments.
Our mission is to translate deep technical breakthroughs into operational reality, solving some of the hardest systems-level problems in industry.

Role Overview

We are looking for an AI Vision Engineer to help design, build, and deploy next-generation computer vision systems across a diverse set of real-world industrial applications.

This role is ideal for someone with a strong foundation in Computer Vision and Machine Learning who is excited about working across the full vision stack, including classical and deep-learning-based CV, vision-language models (VLMs), multimodal reasoning, and real-time inference at the edge and in the cloud.

You will work closely with our AI and engineering teams to develop production-ready vision solutions, improve model performance, and help shape the next generation of intelligent visual systems.

What You'll Do
  • Design, train, evaluate, and deploy computer vision models for real-world industrial applications.

  • Build and optimize CV pipelines for tasks such as object detection, segmentation, classification, OCR, tracking, and visual understanding.

  • Develop and fine-tune vision-language models (VLMs) for multimodal reasoning, visual question answering, and document understanding.

  • Design and optimize real-time inference pipelines for deployment on edge devices and in the cloud.

  • Build scalable data pipelines for image and video collection, annotation, augmentation, training, and evaluation.

  • Fine-tune and evaluate open-source vision and multimodal foundation models using modern training and inference frameworks.

  • Develop robust evaluation frameworks and benchmarks to measure model accuracy, robustness, latency, and business impact.

  • Optimize models for production constraints, including quantization, pruning, and hardware-accelerated inference.

  • Collaborate with product, engineering, and research teams to translate business requirements into technical vision solutions.

  • Contribute to architecture decisions, technical design reviews, and AI/CV best practices.

  • Stay current with the latest advancements in computer vision, multimodal AI, and autonomous systems.

Required QualificationsEducation

Bachelor's degree in Computer Science, Computer Engineering, Electrical Engineering, Mathematics, Statistics, Artificial Intelligence, or a related technical field, or equivalent practical experience.

Experience & Skills
  • 3+ years of industry experience in Computer Vision, Machine Learning, Applied AI, or related fields.

  • Demonstrated experience independently owning and delivering computer vision projects from concept to production.

  • Strong programming skills in Python.

  • Hands‑on experience with PyTorch and modern deep learning workflows.

  • Experience developing and deploying computer vision models (detection, segmentation, classification, OCR) in production environments.

  • Experience working with image and video processing libraries such as OpenCV.

  • Experience with common CV/detection frameworks (e.g., YOLO, Detectron2, MMDetection, or similar).

  • Experience working with VLMs, multimodal models, or Generative AI applications.

  • Strong understanding of machine learning fundamentals, model evaluation, experimentation, and model deployment.

  • Experience working with Hugging Face Transformers and open-source AI ecosystems.

  • Familiarity with data annotation workflows, dataset curation, hyperparameter optimization, and inference optimization.

  • Experience building production‑grade software and AI systems.

  • Strong analytical and problem‑solving skills.

  • Excellent communication and collaboration skills.

Preferred Qualifications
  • Master's degree in Computer Science, Artificial Intelligence, Machine Learning, Computer Vision, or a related field.

  • Experience with OCR, document understanding, or visual reasoning systems.

  • Experience with Vision‑Language Models (VLMs) and multimodal AI applications.

  • Familiarity with 3D vision, SLAM, or sensor fusion (e.g., camera + LiDAR) for industrial or robotics applications.

  • Experience with real‑time inference optimization (TensorRT, ONNX Runtime, quantization, pruning).

  • Experience deploying models on edge hardware (e.g., NVIDIA Jetson, embedded systems).

  • Experience with LangChain, LangGraph, or agentic AI frameworks combining vision and language models.

  • Experience with vector databases and visual/semantic retrieval systems.

  • Experience deploying AI systems on AWS, GCP, or other cloud platforms.

  • Experience with Docker, Kubernetes, and MLOps workflows.

  • Experience with PostgreSQL and large‑scale data systems.

  • Experience with model serving, distributed training, and inference optimization at scale.

  • Contributions to open‑source projects, technical blogs, research publications, Kaggle competitions, or other demonstrable CV/AI work.

  • Experience working in startup or high‑growth environments.

What We're Looking For
  • A builder who enjoys taking vision systems from prototype to production.

  • Someone comfortable working across classical Computer Vision, deep learning, and multimodal Generative AI.

  • An engineer who is curious, adaptable, and eager to learn emerging vision and AI technologies.
