Role Overview
We are looking for an RF engineer who is excited by the challenge of building cutting‑edge RF modules in a fast‑moving start‑up environment. You will collaborate with IC designers, systems engineers, and software teams to integrate advanced RF technologies into high‑performance multi‑chip modules and help drive innovative wireless solutions to market.
Key Responsibilities
- Design and develop RF front‑end circuits and RF functional blocks to meet the specified performance requirements.
- Collaborate with internal and external IC design teams developing integrated digital tunable capacitors, power amplifiers (PAs), low‑noise amplifiers (LNAs), RF switches, digital interfaces, and power management solutions.
- Integrate these design blocks into multi‑chip modules, ensuring low‑loss and high‑performance implementations.
- Optimise module layouts to balance size, performance, and manufacturability.
- Work closely with applications, systems, algorithm, and software teams to optimise overall module performance within target applications.
- Partner with internal stakeholders and test teams to define, develop, and deliver comprehensive module test plans.
- Operate effectively in a fast‑paced, highly innovative start‑up/scale‑up environment.
- Communicate and collaborate efficiently across multidisciplinary teams.
- Document results, design decisions, and technical work clearly, and share knowledge with team members.
