Principal RF Hardware Engineer

COMPANY AnySignal is developing the next generation of RF products and services for some of the most demanding space and defense missions. We’re building a flexible, high-performance platform that’s easy to deploy, monitor, and scale, enabling customers to bring advanced radio technologies to life faster than ever before. THE ROLE We're hiring a Principal RF Hardware Engineer to own the design of the RF hardware at the core of our space radios. This is the most senior individual contributor role on the RF hardware team, and it is a permanent IC role rather than a path into management. You will own designs end to end — architecture and cascade budgets, schematic, layout direction, bring-up, characterization, and support through qualification and flight. You will also set the technical standard for RF hardware here: how designs are reviewed, what verification is expected before a board is released, and what documentation has to exist after. Our radios fly, so the work is judged on what survives launch and performs on orbit. WHAT YOU'LL DO - Own space radio RF hardware designs end to end: architecture and cascade budgets, schematic capture, layout direction, board bring-up, characterization, and support through qualification and flight. - Design and analyze receive and transmit chains — LNAs, mixers, filters, amplifiers, frequency synthesis and PLLs, data converters, and the high-speed interfaces into the digital section. - Own cascade performance: noise figure, gain and flatness, linearity and IM3, spurious, phase noise, EVM, and end-to-end sensitivity, with analysis you can defend against bench data. - Drive PCB stackup, controlled-impedance routing, RF layout, grounding and shielding strategy, and thermal considerations at the board level — working through layout rather than handing off a schematic and walking away. - Run bring-up and characterization on the bench: VNA, spectrum and signal analyzers, signal generators, noise figure meters, high-speed scopes, TDR. - Select and qualify EEE parts for the space environment: derating, radiation tolerance and single-event effects mitigation, screening, upscreening, and reliability analysis. - Support environmental qualification, and lead failure analysis and anomaly resolution when hardware misbehaves — on the bench or on orbit. - Set the technical standard for RF hardware: simulation and verification expectations, design review rigor, and documentation that outlives the designer. - Raise the bar around you through design reviews, mentorship, and technical interviewing — influence through demonstrated judgment rather than reporting lines. REQUIRED SKILLS - 10+ years designing RF and microwave hardware, with genuine depth rather than adjacency. - Multiple programs with hardware you personally designed that has flown and operated on orbit. - Demonstrated end-to-end ownership: architecture and budgets, schematic, layout direction, bring-up, and bench characterization on the same designs. - Expert-level ECAD (Altium preferred) and RF/EM simulation tools such as ADS, Microwave Office, HFSS, or CST. - Excellent first-principles command of RF fundamentals, and the ability to derive rather than look up. - Strong bench skills, including soldering, rework, and methodical debug of boards that don't work yet. - Working practice in space-grade parts selection, derating, and reliability — you know why a part that works on the bench still doesn't fly. DESIRED SKILLS - Software-defined radio architectures, direct RF sampling, and wideband data converters. - Integration experience with Xilinx MPSoC or RFSoC devices. - Phased array, beamforming, or multi-channel coherent system experience. - Enough DSP and communications theory fluency to argue productively with the FPGA and waveform teams. - Python or equivalent scripting for automated test and data analysis. - Track record as the named technical authority on a program, holding a design position under schedule and customer pressure. COMPENSATION The estimated base salary range for this role is $210,000 – $260,000 per year, plus equity. This range reflects our good-faith estimate for this position at the time of posting. The final base salary offered will depend on a variety of factors, including the candidate's qualifications, relevant experience, skills, and market considerations. In addition to base salary, total compensation includes an equity grant and our full benefits package (Medical, Dental, Vision), HSA's and 401K program. ADDITIONAL INFORMATION In order to comply with the space technology export rules of the U.S. Government, such as the International Traffic in Arms Regulations (ITAR), it is necessary to be a U.S. citizen, a lawful U.S. permanent resident, a protected individual as specified by 8 U.S.C. 1324b(a)(3), or possess eligibility to secure the necessary authorizations from the U.S. Department of State. For additional information on ITAR, please seek further details.
