Machine Learning Engineer Intern (Summer 2026)

About this role

Overview Pulse is tackling one of the most persistent challenges in data infrastructure: extracting accurate, structured information from complex documents at scale. Our breakthrough architecture combines schema mapping with fine-tuned extraction models where legacy OCR and parsing consistently fail. We’re a small, fast-growing team in San Francisco powering Fortune 100 enterprises, YC startups, public investment firms, and growth-stage companies. We’re backed by tier-1 investors and scaling quickly. About the Internship As a Machine Learning Engineer Intern, you’ll work directly with our founding engineers on core ML challenges at the intersection of computer vision, NLP, and data infrastructure. This internship is designed for second- or third-year undergraduate students eager to gain hands-on experience in production-scale AI systems. Responsibilities Train and fine-tune OCR, layout, table, and vision-language models Contribute to evaluation, data curation, and active learning pipelines Optimize inference, batching, and quantization on GPU Collaborate with engineers to productionize models with reliability in mind Document findings that inform the model roadmap Requirements Currently an undergraduate student in Computer Science, Engineering, or a related field Strong experience with Python and PyTorch or JAX Familiarity with modern vision or multimodal architectures Solid programming skills and interest in production systems Nice to Have Experience with distributed training or model optimization (Triton, TensorRT, ONNX) Open source contributions in ML/NLP/CV Compensation $40–$70 per hour (depending on experience) Daily meal stipend, office perks, and close mentorship from the founding team
