Principal Engineer:  GaN and GaAs HEMT Technology Roadmap

Skyworks Solutions is seeking a Principal Engineer responsible for the planning and execution of its compound semiconductor technology roadmap to support products used in 5G, Wifi and mmW infrastructure communication systems, such as RF front-ends modules for massive MIMO base stations, Wifi access points, mmW antenna arrays and satellite communication systems.


The candidate will be part of the Technology and Modeling Team within Skyworks Diversified Analog and Audio Solutions (DAAS) business unit, which is focused on the creation, delivery, and support of new technology platforms to the product development teams, including silicon and compound semiconductors, BAW filters, RF packaging, advanced modeling, and RF IP development.





The candidate will interface directly with marketing and product line managers, with application, design and systems engineers, as well as with process, device and modeling engineers to define a long term technology roadmap and ensure proper and timely execution. Tasks will include the definition of process and cost targets, as well as schedule and critical milestones to support the product roadmap. The candidate will be responsible for the management of the following technologies: GaN HEMT, GaAs pHEMT and high power passives. The position requires a holistic approach to technology development and will require to account for sourcing, cost, design, qualification, reliability, yield, resources and schedule tradeoffs.


As the critical interface between the business unit and both the internal and external foundries, the candidate shall guide, influence and challenge both internal and external stakeholders to deliver innovative solutions on time and on budget. The position might also require a hands-on approach in term of simulation, layout and lab evaluation.


The candidate must have an in-depth working knowledge of III-V technologies and experience designing PA or LNAs in RF compound semiconductor technologies such as GaAs or GaN HEMT. The ideal candidate will be a seasoned RF PA or LNA design engineer with a strong interest in technology development and co-optimization of semiconductor processes and product.


The candidate will report to the Director of Compound Technologies within the Technology and Modeling Team of Skyworks Diversified Analog and Audio Solutions (DAAS) Business Unit.

MSEE + 10 years or PhD + 8 years of relevant experience

Experience with GaN HEMT (process or product design) is required

Experience with HBT, PIN diodes and MIS caps is beneficial

History of releasing III-V technology and/or RF IC products to the marketplace is required

RFIC design and layout experience with compound technologies. Exposure to silicon and packaging technologies is a bonus

Understanding of HEMT operation, as well as the influence of the Epi layers and substrate on device performance

Familiar with RF amplifier modes of operation and figure of merits (at the product and device level)

Strong experience with reliability and thermal considerations for high power or high reliability applications

Experience with cellular and WIFI standards is a plus

Experience guiding failure analysis

Expertise with Keysight ADS and/or Cadence and associated simulation engines and data

Experience with IC layout using Cadence Virtuoso, including LVS and DRC

Experience with EM tools such as EMX, HFSS or Momentum

Ability to work on multiple projects and technologies in parallel

Lab skills to perform or assist with characterization and debugging using RF test equipment.

Team player with a focus on product requirements and schedule.

Excellent oral and written communication skills.



Create and update the technology roadmap for GaN HEM, GaAs pHEMT and high power passives (IPD). 

Drive the execution of the roadmap by working with internal and external stakeholders including marketing, packaging, reliability, design, internal and external foundries, modeling and enablement teams.

Assess new technology offering through benchmarking using foundry documentation, custom test structure creation and characterizations or demonstrations through proof of concepts

Initiate and manage new technology development (internal development or Joint Development Agreement with external foundries) by building business cases including ROI and risk analysis, and presenting and defending them to the senior executive team.

Systematically and methodically address all risks and gaps during technology development and initial manufacturing ramp by leveraging technical expertise and product insight. Vet and drive the execution of all aspects of the technology development phases performed by other internal teams or external foundries.

Directly contribute to or supervise the planning, definition, simulation, layout and characterization of test vehicles

Communicate and report progress to management and stakeholders through concise executive and technical review meetings.
