About The Position

ARES Corporation seeks an experienced electrical circuit analyst to support Blue Origin’s Lunar program. The role focuses on independent electrical simulation and Worst Case Circuit Analysis (WCA/WCCA) of aerospace circuits and RF components to verify performance against NASA and industry-standard requirements from beginning-of-life through end-of-life conditions, accounting for tolerances, temperature, aging, radiation, and environmental extremes. The analyst evaluates worst-case performance of RF circuits used in lunar systems, including low-noise amplifiers, solid-state power amplifiers, mixers, filters, oscillators, switches, PLLs, and software-defined radio front-ends. The position works independently with minimal oversight and collaborates with Blue Origin engineering teams to provide technical evaluations, margin assessments, and design recommendations. Well-qualified remote candidates will be considered. Candidates local to the Denver metro area, including Blue Origin’s South Denver / Highlands Ranch presence, who are willing to work a hybrid schedule are preferred.

Requirements

Bachelor’s degree in Electrical Engineering or a related technical field.
At least 6 years of professional experience in RF circuit design, analysis, or simulation for aerospace, space systems, or high-reliability electronics, including significant hands-on WCA/WCCA experience.
Demonstrated experience independently performing WCA/WCCA or equivalent detailed electrical performance analysis on RF, microwave, or high-reliability analog circuits for aerospace, space, or similarly critical applications.
Strong proficiency with SPICE-based circuit simulation tools such as LTspice, PSpice, or equivalent, including Monte Carlo, parametric, and sensitivity analysis capabilities.
Knowledge of RF circuit performance parameters and worst-case considerations, including stability, impedance matching/VSWR, gain/noise figure, power compression, linearity, phase/group delay, and packaging/layout effects.
Experience incorporating environmental, aging, and radiation effects into analyses and applying part derating practices for space applications.
Excellent analytical, problem-solving, and technical communication skills, including the ability to present complex findings clearly to customers and senior technical stakeholders.
Ability to work independently with minimal oversight while maintaining technical rigor and accountability.
Familiarity with radiation effects on RF components and integrating radiation data into WCA.

Nice To Haves

Experience with RF/microwave tools such as Keysight Advanced Design System (ADS) or equivalent, including harmonic balance and S-parameter analyses.
Direct experience supporting commercial space programs, such as Blue Origin, Artemis-related, or similar lunar/human spaceflight efforts, or high-reliability RF systems for NASA/DoD programs.
Experience developing or reviewing WCCA reports according to industry standards.
Background in schematic capture, PCB layout awareness for RF parasitics, or model correlation with hardware measurements.
Experience with related analyses such as parts stress analysis, signal integrity, or reliability assessments.
RF, microwave, or analog emphasis in the degree field.

Responsibilities

Independently perform electrical simulations and WCA/WCCA on aerospace RF and mixed-signal circuits using Extreme Value Analysis (EVA), Root-Sum-Square (RSS), and Monte Carlo methods.
Account for initial part tolerances, temperature coefficients, aging, radiation effects including TID, supply variations, and layout and packaging parasitics.
Execute analyses in accordance with NASA and industry WCA/WCCA requirements and guidelines; develop and maintain WCCA plans, compliance matrices, and supporting documentation.
Build and maintain part variation databases; develop, review, and correlate SPICE and RF models, including S-parameters and nonlinear models, with hardware test data.
Incorporate electromagnetic effects where relevant to RF performance, including gain, noise figure, VSWR, stability, compression points, intermodulation, and phase noise.
Work with Blue Origin engineering teams to define analysis scope and review circuit designs and schematics.
Evaluate worst-case performance against requirements, identify risks and margins, and recommend design mitigations or verification approaches.
Present technical findings and rationale in reviews.
Produce rigorous WCCA reports and supporting analyses.
Coordinate with systems engineering, reliability, safety, and other disciplines on interface requirements and mission assurance.
