Hardware Design Engineer – Wireless Communications Location: Cambridge region | Hybrid working available Type: Permanent | Competitive salary annual bonus Overview We’re working with an established technology company developing advanced wireless communication systems and high-performance radio hardware. The team designs products used across multiple sectors — from cellular infrastructure to specialist communication and test systems — and covers the full lifecycle from concept through to manufacture. As an RF Hardware Design Engineer, you’ll work alongside experienced electronics and RF specialists on technically challenging, multi-disciplinary projects that integrate analogue, digital, and RF design. Key Responsibilities Capture and interpret hardware requirements, contributing to RF design at both circuit and system level. Design complex mixed-signal PCBs, including schematic capture and component selection. Characterise and validate new designs using standard lab instrumentation (oscilloscopes, signal and spectrum analysers, VNAs, etc.). Evaluate new ICs and technologies for inclusion in next-generation products. Collaborate closely with software, FPGA, and RF teams to deliver integrated hardware platforms.About You You’re an engineer who enjoys hands-on design, debugging, and developing reliable, high-performance RF focused hardware. You’ll be joining a team that values curiosity, problem-solving and collaboration, with opportunities to broaden your skills across multiple technology domains. Essential Skills & Experience Degree or equivalent qualification in Electronic Engineering or related discipline. 4 years’ experience in RF/electronic hardware design within wireless or embedded systems. Strong circuit design knowledge (analogue and mixed-signal). Experience designing PCBs with high-frequency and precision components (e.g. RF front ends, oscillators, ADCs/DACs, LNAs, filters). Skilled in debug, validation and fault-finding using lab tools. Self-motivated, structured, and able to deliver under minimal supervision.Desirable Skills Understanding of mobile or wireless communication systems (e.g. 5G, LTE, or similar). Familiarity with RF/microwave design principles and transmission line theory. Experience with scripting or programming for test automation or data analysis (e.g. Python, MATLAB). Awareness of regulatory compliance and product lifecycle management systems.What You’ll Get Competitive salary and performance bonus. Variety of technically engaging projects across multiple wireless domains. Supportive, flexible culture with opportunities for learning and professional growth.Eligibility Candidates must have the right to work in the UK
