About The Position

The High Frequency Technology Center (HFTC) is seeking an R&D Process Engineer to develop, maintain and optimize manufacturing processes to fabricate passive interposer substrates for Keysight’s Heterogeneous Integration technology. This position is onsite at Keysight Headquarters in Santa Rosa, CA. Live in beautiful Sonoma County amongst vineyards, redwood forests, rivers, lakes and coastline while working on state-of-the-art advanced packaging technologies. The Process Engineer will own process development and process control to meet quality and production metrics. Responsibilities include a combination of R&D and manufacturing in partnership with Design, Integration, Test, Operations, Maintenance, Product and Failure Analysis teams. The Process Engineer is accountable for yield, cycle time, throughput, and quality of their process. This role involves technical depth in semiconductor processing, strong hands-on aptitude, as well as effective communication and teamwork to meet department-level objectives. Process Development Engineers at HFTC are responsible for process development and sustaining of custom, cutting-edge, micro and nano-fabrication technologies. The focus of this position is process development, manufacturing sustainability, and R&D support for new product introductions, with specialization in wafer fab processes.

Responsibilities

Ownership of metrology tools for wafer fabrication and/or advanced packaging. Examples: ellipsometry, CDSEM, overlay, profilometry, X-ray fluorescence, particle inspection, automatic optical inspection, and four-point probing
Own metrology strategy and performance by developing recipes, sampling plans, and SPC methodologies to ensure precise, accurate, and high‑throughput measurements.
Drive process control and stability through SPC charting, daily reviews, root‑cause analysis, and corrective actions using statistical tools (e.g., JMP).
Working closely with other process, integration, product, and circuit design engineers to define process and performance targets.
Defining process flows, develop new processes and drive continuous process improvement (CPI) efforts to maximize product yield.
Report process metrics, root cause investigations, and process change implementations at the department level.
Ensuring successful process hand off to manufacturing partners.
Working with Operations to implement robust process control and support production processes; diagnose and resolve process problems with urgency.
Leading capital equipment acquisition projects that include tool evaluation, characterization, process development, and qualification.
Enable advanced data and tool capabilities by supporting tool qualification/matching, automation, robust data pipelines, and real‑time process visibility.
Broader experience in upstream and downstream processes and ability to understand process interactions.
