Senior RF Filter Engineer

I’m supporting a long-standing client based near Leeds, a leading RF/microwave technology manufacturer working across space, defence, high-reliability communications and next-generation connectivity hardware. They’re scaling quickly, with record commercial growth and major programme wins across their filter, mmWave and subsystem product lines.

They’re now looking to bring in a Senior RF Filter Engineer to take ownership of RF/microwave filter design projects from concept through to delivery. This Senior RF Filter Engineer will sit within their core RF/microwave engineering group, focusing on advanced filter design, NPI support and cross-functional collaboration across engineering, operations and customer-facing functions.

You’ll lead the design, simulation, prototyping, tuning, verification and release of high-performance RF/microwave filters and filter-based subsystems, supporting both R&D activity and customer programmes. The focus is on delivering technically strong, manufacturable designs that meet performance, cost and schedule targets.

• Own end-to-end RF/microwave filter and sub-system design — simulation, prototyping, validation
• Contribute to next-generation filter R&D initiatives
• Support sales/commercial teams during quotation phases and engage directly with customers when required
• Compile and check all design documentation (logbooks, data packs, reviews, NPI documentation) for design release
• Deliver fully verified, production-ready designs within project constraints
• Prepare and review tollgate documentation in line with internal NPI processes
• Lead and participate in design reviews, identifying risks and mitigation actions
• Conduct full design verification and validation (test plans, reports, reliability testing)
• Maintain an accurate design compliance matrix with evidence of compliance
• Support product introduction, troubleshoot issues and create diagnostic/training procedures

• Degree (or equivalent) in RF/Microwave Engineering or related field
• Strong experience in RF/microwave filter design including tolerance/yield analysis, power handling, thermal drift and DFM considerations
• Skilled in Microwave Office, CST Studio and Spark3D
• Hands‑on tuning experience with RF/microwave filters using VNAs, power‑handling and temperature testing
• Strong documentation and communication skills, able to work effectively with customers and internal teams
• Highly motivated, proactive and comfortable working across multi‑disciplinary engineering functions

Responsibilities may evolve as programmes and customer needs grow.
