AnySignal is developing next-generation RF products and services for space and defense missions. We're building a flexible, high-performance platform for advanced radio technologies. You will be the most senior individual contributor on the RF hardware team, owning the design of RF hardware at the core of space radios. This is a permanent IC role focused on technical depth rather than management. Key responsibilities: - 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 including LNAs, mixers, filters, amplifiers, frequency synthesis, PLLs, data converters, and high-speed digital interfaces. - Own cascade performance metrics: noise figure, gain and flatness, linearity and IM3, spurious, phase noise, EVM, and end-to-end sensitivity with defensible analysis. - Drive PCB stackup, controlled-impedance routing, RF layout, grounding and shielding strategy, and thermal considerations—working through layout rather than handing off schematics. - Run bring-up and characterization on the bench using VNA, spectrum and signal analyzers, signal generators, noise figure meters, high-speed scopes, and TDR. - Select and qualify EEE parts for the space environment: derating, radiation tolerance, single-event effects mitigation, screening, 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 through design reviews, mentorship, and technical interviewing—influence through demonstrated judgment rather than reporting lines. REQUIREMENTS: - 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 with ability to derive rather than look up - Strong bench skills including soldering, rework, and methodical debug of boards - Working practice in space-grade parts selection, derating, and reliability 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 - DSP and communications theory fluency to engage productively with FPGA and waveform teams - Python or equivalent scripting for automated test and data analysis - Track record as named technical authority on a program under schedule and customer pressure Note: ITAR compliance required—must be U.S. citizen, lawful permanent resident, or possess eligibility to secure necessary authorizations from U.S. Department of State.
