AOptix Looking for RF Architect & Field Engineer

• End-to-end product development (concept, design, implementation, test, production, and support) of the millimeter wave radio portion of our communications product line
• Design high-performance RF transceivers and baseband radios, starting from design requirements, up through cascade analysis, component selection, schematic design, simulation, layout, and test.
• Perform analysis and simulation of both linear and non-linear circuits such as phase-locked loops, vector modulators/demodulators, oscillators, mixers, multipliers, synthesizers, low noise and/or power amplifiers
• Perform/Oversee testing on new designs to ensure requirements such as gain, noise figure, 1db compression point, distortion limits, and impedance matching are met
• Prepare and release designs for manufacturing of both prototype and production parts, and support products through regulatory testing

• M.S. in electrical engineering, PhD. preferred
• 15+ years of experience in E-band millimeter wave, microwave, or radar systems industry.
• Proficiency in performing detailed microwave/millimeter wave and baseband communications circuit and subsystem design (e.g., filters, amplifiers, oscillators, mixers, detectors, modulators & demodulators, interconnect) while meeting unique customer requirements for power, weight, size, modulation, and protocols.
• Practical and theoretical foundation in module and system-level microwave/millimeter wave test and troubleshooting
• Ability to integrate microwave/millimeter wave and baseband sub-systems on both new and existing platforms and devices.
• Must have experience characterizing radio performance in, X-Band and E-Band frequencies
• Must have knowledge of digital communication systems and modulation types such as FSK, BPSK, QPSK, QAM, and OFDM
• Experience in frequency synthesis, filter design, impedance matching, carrier recovery, direct conversion transceivers, gain cascades, equalization and limiting amplifiers.
• Thorough understanding of RF passive components such as Hybrid couplers, Wilkinson dividers, waveguides, circulators, and directional couplers
• Experience with high speed, high performance digital and RF PCB design, including understanding of cross talk and EMI suppression as relevant to PCB design
• Familiarity with using VNAs, oscilloscopes, spectrum analyzers, etc and in-system debugging
• Excellent oral and written communication and interpersonal skills.

• Flexibility with hours during weeknight or weekends as needed

• Work closely with our customers, as well as interface with sales, product management, engineering and operations teams to provide needed technical solutions to suit the customer needs.
• Dependent on location, this position requires up to 80% travel, both domestic and international.
• Troubleshoot, debug and test field issues and product problems.
• Contribute to Installation and Troubleshooting guides and manuals and other technical product documentation.
• Evaluate, validate, and present technical solutions to customers.
• Own question and answer discussions with customers.
• Ensure that products are successfully installed and accurate as sold to the customer.
• Provide ongoing post-sales technical support to customers and look for opportunities to strengthen the partnership relationship.
• Make suggestions for Product Roadmap.

• 5+ years experience in post sales support of broadband RF systems with emphasis point-to-point microwave radios in the 6 -40 GHz bands (80 GHz band experience a plus)
• Minimum associate degree or extensive practical experience/knowledge in wireless technology
• Proven leadership ability and knowledge of wireless industry required.
• Previous start-up experience is preferred.
• Excellent written, verbal, interpersonal, communication, and presentation skills required.
• Location in Silicon Valley
