Senior/Application Engineer


Full Time

About the Role

As Application Engineer, your key responsibilities consist of meeting customers technical requirements using our portfolio of devices, demonstrate optimum and competitive performances to enable design-in. You will be involved in product definition and characterisation, develop demonstrators, optimization in customer applications, support ramp up in mass production as well as failure analysis.

To be effective in fulfilling your role requires in-depth knowledge of our products. You will also need to be familiar with the product development process from R&D, testing through to production.

You’re expected to be a strong team player, resourceful, able to collaborate and work closely with various team members internal as well as external to achieve company goals and objectives.

Duties and Responsibilities:

  • Using CAD tools and Load-pull measurement, develop demo-boards (High Power GaN Doherty, Driver, Small Signal GaAs LNA/ Gain Block, Driver) to evaluate new design

  • Optimize demo-boards performances (RF matching, fine tuning) to meet customers specifications and initiate design-in opportunities at customers

  • Collaborate across multiple engineering disciplines, including product, test, design, and marketing to support/answer customers’ needs

  • Interact with customers to understand their current and future needs for radio architecture and be able to translate that into requirements for new products

  • Work closely with product marketing to define future new RF products

  • Write technical documentation including application notes, white paper, etc

  • Have a thorough understanding of the radio signal chain (Tx and Rx) and exposure to different radio architectures

  • Understanding of mobile communication standards (LTE, NR, etc), global spectrum regulations (3GPP, FCC etc.) and their specifications for radio performance is an advantage

  • Expert in RF laboratory equipment and measurement techniques including power amplifier circuit assembly and tuning

  • RF board level design and experience

  • Familiar with simulation tools such as Keysight ADS suite, IQSTAR Circuit Measurement and Analysis Software, 3D EM Simulation HFSS, AutoCAD (or equivalent).

Skills and Abilities:

  • Good understanding and insight into customers’ target application for our type of products

  • Ability to present and explain complex technical ideas to a variety of audiences

  • Demonstrated expertise in setting up and using RF/Microwave test equipment
