About the Role
An innovative semiconductor startup is seeking an experienced Senior RFIC/MMIC Design Engineer to develop next-generation high-frequency RF systems for advanced radar and satellite communications applications.
The company is developing a multi-material, 3D semiconductor platform that integrates chip, packaging, and materials technologies to deliver high-performance RF solutions.
This role offers significant technical ownership, from circuit architecture and design through hardware validation, within a small, highly technical engineering team.
Key Responsibilities
- Own end-to-end RFIC/MMIC circuit design for high-frequency active RF systems, from architecture and implementation through validation and hardware debugging.
- Design and optimize RF circuits, including power amplifiers (PAs), low-noise amplifiers (LNAs), and beamforming-related components.
- Develop high-performance RF solutions for radar, satellite communications, and other demanding microwave/mmWave applications.
- Collaborate closely with packaging, systems, and materials engineers to optimize chip-level and package-level performance.
- Evaluate and resolve complex circuit design trade-offs involving performance, power, materials, and integration.
- Lead RF hardware characterization, measurement, debugging, and performance optimization.
- Contribute to the development of engineering methodologies and design processes within an early-stage semiconductor environment.
Required Qualifications
- Strong hands-on experience designing RFIC/MMIC circuits, with demonstrated personal ownership of completed hardware designs.
- Expertise in active RF circuit design, particularly power amplifiers, low-noise amplifiers, or beamforming-related circuits.
- Experience working with microwave or millimeter-wave systems for radar, satellite communications, or similarly demanding applications.
- Strong understanding of RF circuit architecture, design trade-offs, and performance optimization.
- Hands-on experience with RF hardware validation, characterization, measurement, and debugging.
- Ability to explain technical design decisions, measured performance, and lessons learned from completed hardware projects.
- Comfortable working in a small, fast-moving engineering team with significant individual responsibility.
Preferred Qualifications
- Experience developing RF circuits for radar or low Earth orbit (LEO) satellite communications.
- Expertise in X-band, K-band, Ka-band, or adjacent microwave/mmWave frequencies.
- Familiarity with semiconductor technologies including GaN, GaAs, SiGe, and CMOS.
- Experience with heterogeneous integration, advanced semiconductor packaging, or chip-package co-design.
- Background in early-stage semiconductor companies or developing new RF hardware platforms.
Why Join?
- Significant ownership of RFIC/MMIC design from initial architecture through working silicon.
- Opportunity to work on advanced semiconductor technologies combining RF circuits, heterogeneous materials, and 3D integration.
- Direct collaboration with technical founders and a highly specialized engineering team.
- Work on technically challenging radar and satellite communications applications.
- Opportunity to influence engineering methodologies, technical direction, and product development at an early stage.
