Senior Microwave Engineer

Job Description:

How do you design microwave electronics that still perform when speed, power and survivability really matter?
At Leonardo, our Electronic Warfare self‑protection systems are deployed across fast jet, UAV, land and naval platforms — operating in some of the most demanding RF environments in the world. As a Microwave Engineer or Senior Microwave Engineer, you’ll help develop and deliver the microwave subsystems that enable these platforms to detect, respond and survive. Based primarily at ourLutonsite, this role offers hybrid working, with on‑site time flexing to meet programme and test requirements.

What you’ll do

What you will do as a Microwave Engineer / Senior Microwave Engineer working on EW programmes:

• Developmicrowave and RF circuits operating to and beyond20 GHz, supporting advanced EW self‑protection systems.
• Contribute to the development ofcomplex RF subsystems, from early prototyping through detailed design, integration and test.
• Perform microwave simulation, modelling and optimisation usingindustry‑standard EM and circuit tools.
• Perform hands‑on RF test, measurement and debug using world‑class laboratory facilities.
• Propose changes / updates as applicable.
• Contribute to and be supported by an Integrated Project Team.
• Engage indesign reviews and technical discussions with internal stakeholders, partners and customers.
• In performing the above, solve technically challenging problems across the RF chain, balancing performance, power, reliability and manufacturability.

What you’ll bring

This role is aimed at engineers withmicrowave or RF expertise who are comfortable operating with some technical autonomy.

Essential experience:

• Proven experience working withRF / microwave circuitryin electronic systems.
• Understanding ofmicrowave theory, high‑frequency effects and practical implementation including layout.
• Experience using one or more of:
  • Keysight ADS
  • Microwave Office
  • CST Microwave Studio
  • Ansys HFSS
  • Siemens EDA / Mentor tools
• Hands‑on experience withRF test equipment, such as network analysers, spectrum analysers and RF sources.
• Ability todebug failing hardware or test setups.
• Practical experienceanalysing results and reporting againstdesign requirements.
• Experience interfacing withcustomers, suppliers or internal stakeholders on technical matters.
• Teamworking:effectivecommunication, undertaking activities in pursuit of the team’s goals and reporting on progress of these.
• Willingness to support and mentor less‑experienced early careers engineers.

Valuable (but not essential):

• Experience working within astructured electronic design lifecycle.
• Exposure toreporting oncost and schedule as well as technical progress.
• Experience within thedefence or aerospace sector.
• Background in regulated or high‑reliability industries.
• HNC/HND or degree‑level knowledge in Electronic Engineering, Physics, Applied Physics or similar — or equivalent practical experience.

Experience in one or more of the following is advantageous:

• RF and microwave layout techniques
• RF synthesisers (DDS or PLL‑based)
• Mixers
• Frequency conversion
• Passive microwave structures (e.g. filters)
• High‑power amplifiers or switches
• Low phase‑noise design and measurement
• RF chain analysis and budgeting
• RF PCB design
• MMICs
• Antennas
• High speed digital circuitry
• Circuits operating acrossmulti‑octave bandwidths
• Model‑driven engineering (MATLAB / Simulink)
• Test automation (e.g. LabVIEW)

How this role grows with you

This role rewardstechnical depth, judgement and delivery.

• Senior engineers operate with significant autonomy, owning complex microwave designs and solving demanding RF problems within EW systems.
• As influence and experience grow, progression toPrincipal Microwave Engineer brings broader technical authority — shaping subsystem architectures, guiding design standards and mentoring others.
  • Principal engineers will play a visible role intechnical strategy, design governance and cross‑programme problem solving.
• Progression is driven bytechnical credibility, product‑level understanding and trust earned through delivery, rather than formal hierarchy.
