What are the responsibilities and job description for the RF Engineer position at Kaizen Stackup?
📡 RF Engineer – Advanced RF Measurement Systems
📍 Location: United States (Lab-Based Limited Travel)
💰 Compensation: Competitive Base Salary Benefits
🕒 Employment Type: Full-Time
🌐 About the Role
Our client is seeking a hands-on RF Engineer to design, build, and support sophisticated RF measurement systems used for antenna characterization, radar cross-section (RCS) testing, and electromagnetic materials analysis.
This is an end-to-end engineering role—ideal for someone who enjoys taking systems from concept to reality, working directly with hardware, and supporting real-world measurement environments.
🛠️ What You’ll Be Working On
-
Design Complete RF Measurement Systems
Build VNA-centric systems for antenna testing, RCS measurement, and EM material characterization. -
Architect RF Signal Chains
Design and integrate RF front-ends including switches, amplifiers, couplers, filters, and calibration paths. -
Build & Validate Systems
Assemble hardware, integrate mechanical positioners and scanners, perform calibration, and verify system performance. -
Solve Complex Measurement Problems
Debug RF, mechanical, and software issues to ensure stable, repeatable, high-quality measurements. -
Install & Support Systems
Support on-site installations, train users, and provide post-deployment troubleshooting. -
Create Clear Documentation
Produce wiring diagrams, test procedures, calibration workflows, and user guides to support long-term system reliability.
🎯 What We’re Looking For
-
Bachelor’s degree in Electrical Engineering or equivalent hands-on experience
-
Strong RF/microwave fundamentals (S-parameters, matching, noise, dynamic range)
-
Proven experience working with Vector Network Analyzers
-
Hands-on comfort with RF lab tools and precision connectors
-
Methodical troubleshooting mindset and strong documentation habits
-
Ability to manage multiple technical workstreams independently
⭐ Bonus Experience (Not Required)
-
Antenna measurement systems (near-field, far-field, anechoic chambers)
-
RCS measurement concepts and calibration techniques
-
EM materials testing and parameter extraction
-
RF front-end design experience
-
Test automation or instrumentation control (Python, MATLAB, LabVIEW, etc.)
-
Familiarity with major RF instrumentation vendors
✅ What Success Looks Like
-
You can turn a vague measurement requirement into a robust, repeatable system
-
You’re just as comfortable tightening a precision connector as you are tuning a calibration workflow
-
Customers trust you during installs and rely on your technical judgment
✈️ Travel & Environment
-
Primarily lab-based
-
Occasional travel for installations and customer support (≈10%)
