This role will be on-site 5 days a week in either our South San Francisco office or our Fremont, CA office. Responsibilities Own technical initiatives from inception to delivery: translate operational needs into technical roadmaps, architectural specs, and deployable code. Architect and scale end-to-end Python backends, spanning high-throughput event pipelines, internal REST APIs, and automated data processing tools. Interface directly with internal clients (production technicians, metrology specialists, and R&D engineers) to diagnose workflow bottlenecks and validate solutions on the floor. Optimize database performance and schema design for high-frequency telemetry, process metrics, and traceability data. Partner with our front-end
