Real-Time Computational Imaging Engineer

Merge Labs; San Francisco (CA); On-site; USD 185,000 - 260,000; Full time

Job summary

Merge Labs is seeking a highly skilled engineer to build and maintain a shared imaging core that turns raw ultrasound data into image series across platforms. You will define performance objectives and develop, optimize, and validate reconstruction methods for real-time imaging and large-scale offline processing.

The role emphasizes improving beamforming, backprojection, and motion estimation, with a focus on speed, robustness, and reproducible benchmarks.

Qualifications

• Strong signal-processing and computational-imaging fundamentals.
• Strong scientific Python skills and experience profiling and improving GPU performance.
• Experience designing and maintaining shared scientific software with clear interfaces, tests, and documentation.

Responsibilities

• Develop reusable methods for beamforming/backprojection, clutter filtering, and motion and displacement estimation within a shared imaging core for processing and optimization.
• Optimize imaging pipelines through controlled experiments, balancing sensitivity, robustness, and computational cost.
• Rigorously validate imaging pipelines using reproducible benchmarks, reference measurements, and regression tests, quantifying performance and uncertainty even when ground truth is limited.
• Produce reliable imaging results, analyze them rigorously, and present findings concisely with their quality and limitations explicit.
• Meet sustained throughput and latency targets for real-time and large-scale offline processing within compute and memory budgets.
• Use measured imaging performance and system limits to shape device and acquisition requirements.
• Explore learned methods, including deep learning, and integrate them when independent evaluation shows a useful improvement over strong baselines.
