Senior​/Principal RF Test Engineer, Texas Institute Electronics

Position: Senior/Principal RF Test Engineer, Texas Institute for Electronics
* Define and own the RF test strategy for TIE’s 3.0D heterogeneously integrated microsystems across K-band (18–27 GHz), Ka-band (27–40 GHz), and W-band (75–110 GHz), spanning wafer, die, module, and system levels.
* Architect end-to-end test flows—from design-for-testability requirements through production screening—ensuring robust, repeatable, and scalable characterization of RF, mixed-signal, and antenna-in-package subsystems.
* Lead development of advanced de-embedding, calibration, and measurement methodologies for novel 3

DHI interconnect structures, including hybrid bonding interfaces, glass/Si interposers, and redistribution layers.
* Drive test-to-model correlation across EM simulation (HFSS, ADS, AWR, CST) and measured data, establishing feedback loops with design, process, and packaging teams to accelerate yield learning and performance optimization.
* Specify, procure, and commission RF test infrastructure—including probe stations, VNA configurations, automated handlers, and environmental chambers—for TIE’s characterization lab buildout.
* Establish and mentor the RF test engineering team, setting technical standards, review processes, and best practices for measurement automation, data management, and statistical analysis.
* Engage with foundry, EDA, metrology, and defense-program partners to define and validate test enablement requirements for next-generation RF packaging technologies.
* Author test strategies, reliability qualification plans, reference test procedures, and design-for-test guidelines that become part of TIE’s Assembly Design Kit (ADK) deliverables.
* M.S. in Electrical Engineering, Microwave Engineering, Applied Physics, or a related discipline with emphasis on RF/microwave measurement and characterization.
* 5+ years of hands-on experience in RF/microwave testing, characterization, or validation of ICs, modules, or packaged systems operating at K-band frequencies and above.
* Deep working knowledge of S-parameter measurement, VNA calibration techniques, de-embedding, and on-wafer probing methodologies.
* Proficiency with RF test instruments (VNAs, spectrum analyzers, signal generators, power meters) and measurement automation using Python, MATLAB, or LabVIEW.
* Familiarity with RF simulation tools such as Keysight ADS, Ansys HFSS, Cadence AWR, or CST Studio for test-to-model correlation.
* Understanding of electromagnetic effects in advanced packaging—signal integrity, coupling, and loss across interposers, redistribution layers, and 3D stacked assemblies.
* Ability to work cross-functionally with design, packaging, EDA, and process teams in a fast-paced R&D environment.

* M.S. in Electrical Engineering, Microwave Engineering, Applied Physics, or a related discipline with emphasis on RF/microwave measurement, calibration science, or test methodology.
* 10+ years of progressively responsible experience in RF/microwave test engineering, characterization, or validation—including at least 3 years in a technical leadership or principal role.
* Expert-level knowledge of S-parameter characterization, advanced VNA calibration (TRL, LRRM, multi-line), de-embedding, and on-wafer probing techniques at millimeter-wave frequencies.
* Proven ability to architect automated RF test frameworks for R&D characterization and production screening using Python, MATLAB, LabVIEW, or equivalent.
* Deep understanding of electromagnetic effects in advanced packaging—signal integrity, coupling, loss, and thermal interactions across interposers, RDLs, and 3D stacked assemblies.
* Strong proficiency with RF simulation tools (Keysight ADS, Ansys HFSS, Cadence AWR, CST Studio) for rigorous test-to-model correlation and root-cause analysis.
* Track record of building or scaling RF test organizations, including lab infrastructure planning, team development, and process definition.
* Ability to influence cross-functional roadmaps and partner with design, packaging, EDA, and program management teams in a defense-adjacent R&D setting.
