Purpose

This role will develop advanced RF and mixed‑signal microsystems for high‑performance communication, radar, and sensing applications, including defining RF front‑end architectures, leading EM/circuit co‑simulation, overseeing RF testing, and collaborating to define design enablement requirements for next‑generation RF packaging.

Responsibilities

• Architect RF and mixed‑signal microsystems operating across K‑band (18–27 GHz), Ka‑band (27–40 GHz), and W‑band (75–110 GHz) for high‑performance, low‑latency communication, radar, and sensing applications.
• Define and drive RF front‑end architectures, including LNAs, PAs, mixers, phase shifters, and T/R modules, optimized for 3.0D integration and advanced packaging flows.
• Collaborate with device, packaging, and digital architects to achieve co‑optimization of RF, thermal, and mechanical performance within heterogeneous multi‑die systems.
• Lead EM/circuit co‑simulation and system‑level modeling using tools such as HFSS, ADS, AWR, or CST to validate and tune design performance across process corners and temperature.
• Oversee RF testing, characterization, and calibration at wafer, die, and module levels—developing test plans, de‑embedding strategies, and measurement automation for K/W‑band hardware.
• Engage with foundry, EDA, and metrology partners to define design enablement requirements for next‑generation RF packaging (e.g., hybrid bonding, AiP, glass/Si interposers).
• Author technical documentation, reference designs, and design guidelines to accelerate ecosystem adoption of TIE’s 3.0D RF microsystems platform.
• Other related functions as assigned.

Required Qualifications

• M.S. in Electrical Engineering, Applied Physics, or related discipline focused on RF, microwave, or millimeter‑wave design.
• At least 8 years of hands‑on experience designing, simulating, and testing RF/microwave ICs or modules (K‑band and above).
• Deep expertise in S‑parameter characterization, on‑wafer measurements, vector network analysis, and de‑embedding methodologies.
• Proficiency with RF simulation and design tools such as Keysight ADS, Ansys HFSS, Cadence AWR, CST Studio, or equivalent.
• Strong understanding of electromagnetic effects in packaging—signal integrity, coupling, and loss across interposers and redistribution layers.
• Proven track record in RF testing automation, data analysis, and test correlation between EM models and measured results.
• Ability to work cross‑functionally with device, packaging, EDA, and system teams in a fast‑moving R&D environment.
• Preferred: Austin, Texas location for close collaboration. Hybrid work arrangements possible with up to 30–50 % travel.
• Relevant education and experience may be substituted as appropriate.

Preferred Qualifications

• Ph.D. in Electrical Engineering, Applied Physics, or related discipline focused on RF, microwave, or millimeter‑wave design.
• More than 8 years of hands‑on experience designing, simulating, and testing RF/microwave ICs or modules (K‑band and above).
• Experience developing Antenna‑in‑Package (AiP), RFIC/SiP, or 3D‑stacked RF front‑end modules for advanced communications or sensing.
• Familiarity with 3DHI design flows and RF/mixed‑signal co‑simulation using advanced EDA environments (Cadence, Synopsys, Siemens, Ansys).
• Hands‑on experience with wafer‑level probing, cryogenic testing, or thermal‑vacuum characterization for high‑frequency systems.
• Knowledge of GaAs, GaN, SiGe, or CMOS RF processes and packaging constraints for high‑frequency operation.
• Publication or patent record in millimeter‑wave circuits, antennas, or RF packaging.
• Strong technical writing and presentation skills for industry and defense‑sector collaborations.

Salary: TIE pays industry‑competitive salaries.

Working Conditions

• May work around chemical fumes.
• May work around standard office conditions.
• May work around chemicals.
• May work around electrical and mechanical hazards.
• Repetitive use of a keyboard at a workstation.
• Use of manual dexterity (e.g., using a mouse).

Work Shift

• Monday–Friday: 8 a.m. to 5 p.m., or flexible between 7 a.m. and 6 p.m.
• Hybrid work arrangements possible, with up to 30–50 % travel.
