Redwire Space Solutions has an opportunity for an RF Engineer I at our facility in Longmont, CO
. This is an early‑career role for an engineer who wants to build a strong foundation in RF systems engineering through modeling, simulation, and analysis. Working alongside senior RF engineers, you will develop and correlate simulation models of RF components and systems, build the software tools that make our analysis faster and more repeatable, and follow those designs through build, test, and delivery.

We are building RF systems for new space and multiple domain communications architectures. This requisition is aimed at candidates completing a bachelor's degree in December 2026, with an anticipated start date in January 2027.

• Develop, correlate, and maintain RF simulation models of components, subassemblies, and end‑to‑end systems using industry standard tools such as Keysight ADS, in order to predict performance and evaluate design trades ahead of hardware build.
• Perform RF component data sheet review and trade studies to compare candidate devices and optimize RF system architecture and performance against gain, noise, linearity, power, size, and cost objectives.
• Build three-dimensional electromagnetic models of RF devices and assemblies in Ansys HFSS, including cavity and enclosure analysis of active devices, to characterize resonances, coupling, and packaging effects that drive gain, isolation, and stability.
• Perform schematic capture and layout of RF printed circuit boards, applying high-frequency design practices such as controlled-impedance transmission lines, grounding and return-path management, and isolation between stages.
• Develop and maintain scripts and software utilities that automate simulation setup, measurement data reduction, and report generation, improving the throughput and repeatability of the RF team's day‑to‑day analysis work.
• Apply engineering principles to ensure designed components and systems meet all requirements such as operational frequency range, signal to noise ratio, system linearity, and stability.
• Support the development, qualification, and delivery of high‑performance RF systems for space and multi-domain environments, under the guidance and mentorship of senior RF engineers.
• Support RF characterization and verification activities in the laboratory and during flight build, test, and delivery. Assist with test setup, collect and process…
