Machine Learning Engineer

• Work closely with applied scientists to design, develop, deploy, and monitor deep learning and ML models for indoor positioning and item localization, owning problems end-to-end.
• Build and improve the training, inference, and evaluation pipelines that take models from prototype to production.
• Optimize models and systems for accuracy, coverage, latency, and cost, and own the trade-offs between them.
• Develop tools and datasets to benchmark performance in real-world, at-scale settings.
• Collaborate with engineering and product teams to prioritize what's worth building and to ship features to enterprise customers.
• Raise the team's engineering bar through reusable infrastructure, better design patterns, and honest technical judgment on architecture and technology choices.

• BSc/MSc in computer science, electrical engineering, or related field with 5+ years of applied ML experience, with at least one system taken personally from ambiguous problem to shipped, measured impact.
• Broad, hands-on command of machine learning (e.g. supervised and unsupervised learning, embeddings and representations, metrics and evaluation) with strong practical judgment on overfitting, generalization, and competing objectives.
• Strong software engineering fundamentals and the ability to write high-quality production code (we work primarily in Python/PyTorch).
• Strong data instincts: comfortable digging into raw data, questioning metrics, and validating your own results.
• Excellent communication skills and ability to collaborate across disciplines.
• Thrive in fast-paced, dynamic environments and take pride in producing high-quality work.

Nice to have

• Deep expertise in a relevant subfield, e.g., time-series models (transformer-based or probabilistic/state estimation), representation learning, computer vision, or multi-sensor fusion (2D/3D perception, pose estimation, tracking, SLAM).
• Background in wireless localization, RFID, or radar signal processing.
• Experience optimizing and deploying ML models in mobile or resource-constrained environments.
• Familiarity with cloud-based model training and inference.
• Research experience, advanced degree, or publications in ML, vision, or systems venues.
• Past startup experience.
