Senior RFIC Design Engineer

Location: Maldon, Essex

Company: Redline Group Ltd

Join a Maldon based, world‑class semiconductor team working on cutting‑edge RF and RFIC technologies. This is a great opportunity to contribute to the design and development of integrated RF solutions in a fast‑paced, customer‑focused engineering environment.

You will play a key role in designing RFIC blocks such as LNAs, mixers, and VCOs operating from MHz up to 6 GHz, contributing to a diverse product portfolio covering both analogue and digital front‑end systems in SiGe and CMOS processes.

Key Responsibilities

• Support product and technology teams by delivering high‑performance RFIC solutions.
• Design and simulate key RFIC building blocks including amplifiers, mixers, and oscillators.
• Carry out schematic capture, layout supervision, and verification using Cadence or Synopsys tools.
• Perform EM simulation and optimisation using tools such as ADS or Momentum.
• Work with cross‑functional teams on block and system‑level integration to ensure robust performance.
• Contribute to design reviews, support silicon debug, and help drive product success from concept to tape‑out.

Qualifications and Skills

• Degree in Electronics, RFIC Design, or a related field, with extensive experience in RFIC development.
• Proficiency in Cadence or Synopsys design environments, including schematic, layout, and verification workflows.
• Experience with EM simulation tools (e.g., ADS, Momentum) and understanding of RF metrics like gain, NF, linearity, and phase noise.
• Familiarity with SiGe and CMOS technologies and a strong grasp of RF design principles across MHz to GHz.
• Excellent communication and collaboration skills, with the ability to solve technical challenges across teams.
