*Do not apply to fixed term and temporary roles YOUR MISSION
True Anomaly is seeking a Principal Space RF Engineer with deep expertise in antenna design and full-wave electromagnetic modeling .
In this role, you will lead the development of antenna and RF front-end solutions for space-based systems. You will own technical efforts from early concept development and electromagnetic analysis through hardware design, testing, integration, and delivery.
The ideal candidate has hands-on experience using full-wave electromagnetic simulation tools to design, analyze, and optimize antennas, arrays, feeds, RF structures, and spacecraft-level electromagnetic interfaces. You will work closely with systems, mechanical, thermal, avionics, manufacturing, and test engineers to deliver high-performance, space-ready RF hardware.
RESPONSIBILITIES
Lead the design and development of space-based antennas and RF front-end hardware.
Perform full-wave electromagnetic modeling and simulation of antennas, arrays, feeds, RF structures, and spacecraft interfaces.
Use tools such as HFSS, CST, FEKO, or equivalent to predict and optimize RF performance.
Analyze antenna gain, radiation patterns, beamwidth, sidelobe levels, polarization, impedance matching, efficiency, isolation, and coupling.
Develop and evaluate fixed-beam, phased-array, electronically steerable, deployable, and conformal antenna architectures.
Conduct electromagnetic trade studies considering performance, size, weight, power, thermal environment, packaging, manufacturability, and cost.
Develop RF front-end architectures, including filters, switches, amplifiers, low-noise amplifiers, feeds, couplers, and RF distribution networks.
Create and maintain antenna models, RF budgets, simulation reports, requirements, and verification plans.
Correlate simulation results with laboratory and antenna-range measurements.
Support antenna and RF hardware integration, troubleshooting, testing, and qualification.
Work with mechanical and spacecraft engineers to resolve packaging, structural, thermal, and electromagnetic compatibility challenges.
Lead technical reviews and serve as a subject-matter expert for antenna and electromagnetic design.
Mentor other engineers and establish effective modeling, design, and test processes.
Support customer engagements, proposals, and new business opportunities as needed.
QUALIFICATIONS
Bachelor’s degree in Electrical Engineering, Electromagnetics, Physics, or a related field. A Master’s degree or Ph.D. is preferred.
10+ years of experience in antenna, RF, electromagnetics, or microwave engineering.
Significant hands-on experience with full-wave electromagnetic simulation and modeling .
Advanced proficiency with one or more full-wave EM tools, such as:
Ansys HFSS
CST Studio Suite
Altair Feko
COMSOL
Similar industry-standard tools
Demonstrated experience designing and analyzing antennas, antenna arrays, feeds, RF structures, or spacecraft RF interfaces.
Strong understanding of antenna theory, electromagnetic fields, wave propagation, impedance matching, polarization, coupling, and radiation patterns.
Experience validating simulation results through laboratory, near-field, far-field, or anechoic chamber measurements.
Experience with phased arrays, beamforming, electronically steerable antennas, or multi-element RF apertures.
Working knowledge of RF front-end components and architectures.
Ability to perform RF trade studies and communicate technical results clearly.
Experience leading complex engineering efforts from concept through design, test, and delivery.
Strong written, verbal, and cross-functional communication skills.
PREFERRED SKILLS AND EXPERIENCE
Experience developing antennas or RF hardware for spacecraft or other space-qualified systems.
Experience with deployable, conformal, body-mounted, or phased-array antennas.
Experience modeling spacecraft-level electromagnetic compatibility, coupling, interference, or antenna-to-structure interactions.
Experience with RF measurements using vector network analyzers, spectrum analyzers, signal generators, antenna ranges, or anechoic chambers.
Familiarity with thermal, structural, vibration, thermal vacuum, and radiation considerations for space hardware.
Experience with MATLAB, Python, or similar tools for RF analysis and simulation automation.
Active TS//SCI clearance or eligibility to obtain one.
Experience working in a fast-paced startup or similarly dynamic environment.
