Senior RF Hardware Design Engineer Cambridge | Hybrid Working Available Competitive Salary + Bonus + Excellent Benefits Develop Technology That Makes a Difference An innovative UK engineering company is seeking a Senior RF Hardware Design Engineer to play a leading role in the development of advanced wireless communications technology deployed in critical operational environments around the world. With a strong order book, long-term customer programmes and significant investment in next-generation product development, this is an opportunity to join a successful engineering business where technical expertise genuinely influences product direction. The Opportunity This is far more than a traditional RF design role. You'll take ownership of RF hardware development across a portfolio of sophisticated wireless systems, helping shape the next generation of products that incorporate advanced cellular and radio technologies. Working in a small, highly capable engineering team, you'll have genuine authority to influence architecture decisions, challenge existing approaches and drive innovation from concept through to production. You'll remain involved throughout the complete product lifecycle rather than handing designs over after schematic completion. What You'll Be Doing * Defining RF architectures for next-generation wireless products * Designing transmit and receive signal chains * Selecting amplifiers, filters, mixers, switches and RF components * Producing schematics and supporting PCB layout activities * Developing mixed-signal and RF hardware for advanced radio systems * Bringing up prototype hardware and validating performance * RF testing, fault-finding and optimisation in the laboratory * Supporting EMC, environmental and regulatory compliance activities * Introducing designs into production and supporting ongoing product improvements * Collaborating closely with software, systems, mechanical and manufacturing teams Key Skills & Experience Essential * Strong commercial experience in RF hardware design and development * Experience taking complex hardware from concept through to production * RF transmit and receive chain design expertise * Practical RF PCB design experience * Strong debugging and fault-finding skills * Experience using RF laboratory equipment including: * Spectrum analysers * Network analysers * Signal generators * RF power measurement equipment * Knowledge of EMC/EMI principles and compliance techniques * Ability to work independently and take technical ownership Highly Desirable Cellular communications experience (GSM, UMTS, LTE and/or 5G) Software Defined Radio (SDR) hardware experience Multi-band RF system design Experience with: RF power amplifiers LNAs Filters Duplexers RF switches RF simulation tools (ADS, CST, HFSS or equivalent) Experience supporting radio or regulatory approvals Low-to-medium volume electronics production experience Why Join? Genuine Technical Ownership You'll influence major architectural decisions rather than simply delivering against a fixed specification. Real-World Impact The technology is deployed in operational environments where reliability and performance matter. Engineering-Led Culture A flat organisational structure where engineers are trusted to solve problems and get on with building great products. Visible Product Development You'll see your work progress from research and development through testing, qualification and production deployment. Profit-Linked Rewards The business operates a highly collaborative ownership-focused model, giving employees a direct connection to company success. What's In It For You? Competitive salary Performance-related bonus Hybrid working flexibility Significant technical autonomy Exposure to cutting-edge RF and wireless communications technology Long-term product development programmes Supportive engineering culture with minimal bureaucracy Opportunity to become the RF technical authority within the business If you're an experienced RF Hardware Design Engineer looking for a role where you can influence product architecture, remain hands-on with hardware, and work on technology with genuine real-world impact, we'd love to hear from you
