RF Lead Engineer

This RF Lead Engineer opportunity sits within a well-funded, fast-growing semiconductor company developing next-generation RF technology for mobile and connected devices. The business is focused on simplifying RF front-end architectures at a system level, enabling more efficient, scalable connectivity across a wide range of applications.

Joining as an RF Lead Engineer, you’ll play a key role in moving cutting-edge RF concepts into real, deployable hardware – working closely with architecture, systems, and wider engineering teams.

As an RF Lead Engineer, you will take ownership of RF subsystem design and delivery within a defined system architecture. This is a hands-on position with real technical depth, combined with leadership responsibilities across design, validation, and team development.

You’ll be expected to drive RF performance from concept through to validation, ensuring designs meet both technical and commercial objectives.

Key responsibilities

RF Technical Leadership

• Lead RF design activities aligned to system-level requirements
• Own RF subsystem performance, implementation, and delivery
• Drive design reviews and provide technical sign-off

RF Design & Development

• Design and simulate RF circuits (LNAs, PAs, filters, duplexers)
• Translate architectural requirements into detailed RF designs
• Optimise RF performance within system constraints

Testing & Verification

• Define and execute RF test and validation plans
• Analyse measurements (S-parameters, NF, EVM, ACPR, phase noise, linearity)
• Lead debugging and root-cause analysis of RF issues

Mentorship & Leadership

• Mentor and support RF engineers within the team
• Promote strong engineering practices and documentation standards

Cross-Functional Work

• Collaborate with system architects and multidisciplinary teams
• Contribute to technical decision-making, planning, and risk management
• Support manufacturing and production test activities

What they’re looking for

• Degree in RF Engineering, Electronics, Physics, or similar
• Strong hands-on RF design experience across relevant frequency ranges
• Proven track record delivering RF projects at a senior/lead level
• Solid understanding of RF theory and real-world implementation
• Experience with tools such as ADS, AWR, CST, HFSS
• Confident using RF lab equipment (VNA, spectrum analyser, signal generator, etc.)

You’ll suit this role if you’re delivery-focused, technically sharp, and comfortable operating in an environment where architecture and productisation are closely linked.

Package & benefits

• Competitive salary + pension
• Share options
• 25 days holiday + bank holidays
• Private medical, life assurance, income protection
• Flexible working options
• Additional benefits platform

Why this role

This RF Lead Engineer position offers a genuine opportunity to influence how RF systems are architected and delivered in next-generation wireless products. It’s a strong fit for someone who enjoys combining deep technical work with leadership and wants to see their designs move into real-world deployment.
