Job summary

E-Space seeks a Senior RF Front-End Engineer to design, develop, integrate, and verify flight RF front-end electronics for spacecraft phased-array antennas and satellite communication systems. You will own from requirements to release, including schematic capture, PCB layout, prototype bring-up, testing, and measurement correlation.

You will analyze circuits, select parts for space reliability, calibrate phased-array channels, and work with RF, antenna, digital, and mechanical teams to meet

Qualifications

• Bachelor's degree in Electrical Engineering, RF/Microwave Engineering, or a related field, with 8+ years of relevant experience; or a Master's degree with 6+ years; or a Ph.D. with 4+ years.
• Hands‑on ownership of RF front‑end hardware from design and analysis through prototype fabrication, bring‑up, and verification.
• Strong understanding of RF fundamentals, including S-parameters, impedance matching, transmission lines, noise figure, gain compression, intermodulation, stability, isolation, filtering, and RF power measurement.
• Experience designing or integrating RF electronics for phased arrays, beamforming systems, radar, wireless communications, satellite communications, or a comparably complex multi‑channel RF system.
• Experience with RF circuit simulation tools such as Keysight ADS, Cadence AWR, or equivalent, and with schematic capture and PCB layout review tools.
• Hands‑on experience operating RF laboratory equipment and independently troubleshooting complex RF hardware.
• Ability to communicate technical issues clearly, work across disciplines, and make data‑driven decisions under schedule constraints.

Responsibilities

• Own RF front-end hardware from requirements and architecture through device-level circuit design, schematic capture, PCB layout, prototype bring-up, qualification, and release.
• Design transmit and receive chains using power amplifiers, low-noise amplifiers, filters, duplexers, switches, couplers, attenuators, mixers, synthesizers, transceivers, phase shifters, beamformer devices, and RF matching networks.
• Perform RF cascade analyses and architectural trade studies covering gain, noise figure, sensitivity, linearity, P1dB, IP3, dynamic range, EIRP, efficiency, stability, spurious performance, and link margin, including simultaneous transmit-and-receive architectures using frequency-division duplexing.
• Define component specifications and select parts based on RF performance, power consumption, thermal behavior, size, manufacturability, availability, cost, reliability, and suitability for the space environment.
• Design and review controlled-impedance transmission lines, grounding, shielding, bias networks, RF PCB stackups, and critical component placement and routing.
• Develop RF and mixed-signal boards incorporating ADCs, DACs, modulation, and demodulation where digitized RF interfaces are required.
• Contribute to RF signal-distribution architectures that transport RF signals over fiber-optic links using analog RF-photonic or digitized approaches.
• Integrate RF electronics with phased-array antenna elements, beamforming networks, digital and baseband electronics, firmware, power systems, thermal systems, and mechanical structures.
• Develop and execute amplitude and phase calibration methods for phased-array RF channels, accounting for channel variation, temperature effects, mutual coupling, and calibration stability.
• Plan and conduct RF characterization using VNAs, spectrum analyzers, signal generators, power meters, noise-figure equipment, oscilloscopes, and near-field or far-field antenna ranges.
• Support environmental qualification of spaceflight hardware, including thermal-vacuum, vibration, and radiation testing.
• Correlate simulation results with measurements, identify the root causes of performance discrepancies, and drive corrective actions through data-driven troubleshooting.
• Document requirements, analyses, design decisions, test procedures, results, and technical risks, and present clear recommendations at design reviews.
• Collaborate with antenna, RF systems, digital, firmware, mechanical, thermal, manufacturing, test, regulatory, and program teams to close requirements and interfaces.
• Mentor engineers and technicians and help establish repeatable RF design, calibration, qualification, and verification practices.
