Job description

Assured Space Access Technologies, Inc. is a defense and engineering firm delivering phased array, radar, RF payload, and secure communications solutions to government and prime contractor customers. We are headquartered in Irvine, California. This role is the technical bridge between our RF products and the customers and partners who integrate and use them.

Team: Engineering

Location: Irvine, CA (on-site, 5 days per week), with customer and field travel up to about 25%

Position Summary

As an RF Applications Engineer, you help customers succeed with our RF products: phased array antennas, ground-based radar, beamforming systems, and our tactical 5G base station. You support them from the first technical conversation through integration, test, and field use, and you bring what you learn back to our design teams.

This is a hands-on, on-site role in Irvine. You will spend time in the lab building demos and reproducing customer issues, on calls and at customer sites supporting integration, and with business development shaping technical solutions. You need strong RF fundamentals, the ability to explain them clearly to engineers and non-engineers, and the judgment to know when to pull in a design expert.

Key Responsibilities

Customer Technical Support

• Serve as the primary technical contact for customers and prime contractors integrating our RF products, from requirements questions through integration and test.
• Diagnose and resolve RF performance and integration issues in the lab and in the field, including reproducing problems on the bench and driving fixes with design engineering.
• Support on-site installations, demonstrations, field tests, and customer acceptance activities.
• Train customer engineers and operators on product setup, configuration, and performance.

Pre-Sales and Business Development Support

• Partner with business development to understand customer requirements and propose technical solutions and configurations.
• Build and run product demonstrations and prepare technical presentations, trade studies, and performance summaries for customers.
• Contribute technical content to proposals, including RF performance analysis and compliance matrices.
• Answer technical questions from customers and partners quickly and accurately.

Product Feedback and Documentation

• Capture field results, customer feedback, and recurring issues, and turn them into clear requirements and improvement requests for engineering.
• Write and maintain application notes, integration guides, interface documents, and troubleshooting guides.
• Characterize product RF performance in the lab and keep an accurate record of results for customer use.
• Work across RF, systems, software, and test engineering so customers get one consistent technical answer.

Required Qualifications

• Bachelor’s degree in Electrical Engineering or a closely related field.
• 6+ years of RF or microwave engineering experience, including at least 2 years in a customer-facing, applications, field, or integration role.
• Strong RF fundamentals: link budgets, noise figure, gain, linearity, impedance matching, S-parameters, and antennas.
• Hands‑on experience with RF test equipment, including network analyzers, spectrum analyzers, signal generators, and power meters.
• Experience integrating and troubleshooting RF hardware at the system level, in the lab and in the field.
• Clear written and verbal communication, including presenting technical material to customers and leadership.
• Willingness to travel to customer and field sites up to about 25%.
• Ability to obtain and maintain a U.S. Secret clearance, which requires U.S. citizenship.
• Ability to work on site in Irvine, CA, 5 days per week.

Preferred Qualifications

• Master’s degree in Electrical Engineering.
• Experience with phased array antennas, radar, beamforming, or AESA systems.
• Experience with cellular or 5G radio systems, private networks, or tactical communications.
• Experience supporting defense customers or prime contractors, including proposals and technical interchange meetings.
• Scripting for test automation and data analysis in Python or MATLAB.
• Active Secret clearance or higher.
