Software Developer – AI

Alliage S/A. • Full-time • San Jose, CA, US • 3w ago

RESPONSABILITIES:

Develop, train, and validate AI/ML models (classification, detection, and segmentation) for medical images and natural images;
Build data pipelines (preprocessing, normalization, registration, augmentation) in Python using PyTorch/TensorFlow;
Explore and adapt reference frameworks for medical and general segmentation, such as nnU-Net (training, post-processing, and evaluation);
Convert and optimize models (PyTorch/TensorFlow → ONNX) and implement inference with ONNX Runtime integrated with C++/Java applications and Python services;
Accelerate inference on NVIDIA GPUs via TensorRT (FP16/INT8) when applicable to production;
Apply image processing concepts (filters, morphology, equalization, registration) in pre/post-processing;
Develop interfaces and support tools (visualization/labeler) in JavaFX (FXML) and/or C++/Qt;
Prototype and integrate LLMs for chatbots/assistants (including RAG and agents) when necessary;
Collaborate with software teams for packaging and monitoring models.

REQUIREMENTS:

Bachelor's degree in Engineering, Computer Science or Related Area;
Solid programming skills in Python and computer vision fundamentals; OpenCV desirable;
Practical knowledge of TensorFlow or PyTorch for training and inference;
Basic knowledge of C++ and/or Java to integrate inference into production (e.g., via ONNX Runtime); familiarity with CUDA/TensorRT is a plus;
Knowledge of Git/GitHub, SQL, and Excel for organizing data and results.

PREFERRED QUALIFICATIONS:

Experience with MONAI and nnU-Net in 2D/3D segmentation.
Experience with conversion/optimization (ONNX, FP16/INT8 quantization) and GPU performance instrumentation (TensorRT).
Practical experience with LLMs (fine-tuning, serving, Transformers) and orchestration (LangChain/RAG).
