Machine Learning Engineer

Overview Pulse is tackling one of the most persistent challenges in data infrastructure: extracting accurate, structured information from complex documents at scale. We have a breakthrough approach to document understanding that combines intelligent schema mapping with fine-tuned extraction models where legacy OCR and other parsing tools consistently fail. We are a small, fast-growing team of engineers in San Francisco powering Fortune 100 enterprises, YC startups, public investment firms, and growth-stage companies. We are backed by tier 1 investors and growing quickly. What makes our tech special is our multi-stage architecture: Layout understanding with specialized component detection models Low-latency OCR models for targeted extraction Advanced reading-order algorithms for complex structures Proprietary table structure recognition and parsing Fine-tuned vision-language models for charts, tables, and figures If you are passionate about the intersection of computer vision, NLP, and data infrastructure, your work at Pulse will directly impact customers and shape the future of document intelligence. What we are looking for 5 days in-office at our San Francisco office Eager to learn and adapt quickly Prior startup or founding experience is a plus About the Role Create the specialized vision and language models that power Pulse. You will have autonomy to train and fine-tune models and to ship improvements to production. Responsibilities Train and fine tune OCR, layout, table, and vision-language models Build evaluation, data curation, and active learning pipelines Optimize inference, batching, and quantization on GPU Productionize models with clear SLAs and rollback plans Write internal notes that inform model and product roadmaps Requirements 3+ years in applied ML or research, or strong open source record PyTorch or JAX, and modern vision or multimodal architectures Solid engineering discipline and metrics focus Nice to have Triton Inference Server, TensorRT, ONNX, distributed training Sponsorship Sponsorship available. Compensation and benefits Competitive base salary plus equity, performance-based bonus, relocation assistance for Bay Area moves, daily meal stipend, medical, vision, and dental coverage.
