Senior RF Front-End Design Engineer - Satellite User Terminals

Ready to make connectivity from space universally accessible, secure and actionable? Then you’ve come to the right place!

E-Space is bridging Earth and space to enable hyper-scaled deployments of Internet of Things (IoT) solutions and services. We are building a highly-advanced low Earth orbit (LEO) space system that will fundamentally change the design, economics, manufacturing and service delivery associated with traditional satellite and terrestrial IoT systems.

We’re intentional, we’re unapologetically curious and we’re 100% committed to innovate space-based communications and deliver actionable intelligence that will expand global economies, protect space and our planet and enhance our overall quality of life.

• Own RF front-end designs from system requirements and architecture through schematic capture, PCB layout, prototype bring-up, verification, and production release.

• Develop transmit and receive chains using power amplifiers, low-noise amplifiers, filters, duplexers, diplexers, switches, couplers, attenuators, mixers, synthesizers, transceivers, and frequency-conversion devices.

• Translate link-budget requirements into RF specifications for output power, sensitivity, noise figure, gain, linearity, dynamic range, bandwidth, EVM, adjacent-channel performance, phase noise, spurious emissions, and efficiency.

• Perform cascaded RF analyses covering gain, noise figure, sensitivity, P1dB, IP3, dynamic range, compression, EVM, phase noise, spurious performance, and link margin.

• Design device-level RF circuits, impedance-matching networks, bias networks, stability networks, power detectors, and protection circuits.

• Select RF components based on electrical performance, power consumption, thermal behavior, size, availability, cost, manufacturability, and reliability.

• Simulate RF circuits using Keysight ADS, Cadence AWR, or equivalent circuit and electromagnetic simulation tools.

• Define and review RF PCB stackups, controlled-impedance transmission lines, grounding, shielding, component placement, isolation, and critical RF routing.

• Develop architectures supporting TDD, FDD, or simultaneous transmit and receive, as required.

• Analyze transmitter leakage, receiver desensitization, harmonics, intermodulation, oscillator leakage, switching noise, and digital interference.

• Integrate the RF front end with the antenna, modem, baseband processor, ADC/DAC, firmware, power system, enclosure, and thermal solution.

• Plan and perform RF measurements using VNAs, spectrum analyzers, signal generators, power meters, noise-figure analyzers, oscilloscopes, and communication signal analyzers.

• Measure and optimize gain, noise figure, sensitivity, output power, EVM, ACPR or ACLR, harmonics, spurious emissions, stability, and efficiency.

• Correlate simulations with measured results, identify root causes of discrepancies, and drive corrective actions.

• Support environmental testing for user-terminal conditions, including temperature cycling, vibration, shock, humidity, and outdoor operation.

• Develop production calibration, test limits, automated test methods, and manufacturing verification strategies.

• Document requirements, analyses, schematics, design decisions, test procedures, results, and technical risks.

• Mentor engineers and technicians and help establish repeatable RF design and validation practices.

• Bachelor’s degree in electrical engineering or a related field.

• Typically 7 or more years of hands-on RF or microwave hardware design experience.

• Demonstrated experience designing RF front-end hardware from requirements through production release.

• Strong understanding of transmit and receive architectures, impedance matching, gain, noise figure, linearity, stability, dynamic range, and RF…
