Antenna Calibration Engineer

ROLES and RESPONSIBILITIES: 

The successful candidate will be working with state-of-the-art over-the-air antenna testing facility for our novel Ku- and Ka-band satcom terminal. This will include leading the set-up and operation of brand-new Compact Antenna Test Ranges (CATR) both in the UK and US. You will be responsible for highly technical calibration and qualifications of the terminals. Using your RF/antenna background, you will integrate MATLAB and Python-based control software to control and synchronise the CATR measurement system with a variety of RF infrastructure, including active RF networks, the satcom terminal (API controlled) and RF test equipment including a Keysight PNA-X, PNA, spectrum analysers, signal generators, power sensors, calibration kits and more. 

This is a fantastic opportunity for an engineer that wants to drive a highly technical, novel calibration and measurement system to a production-standard. The successful candidate will own multiple technical development workstreams to use statistical analysis of large RF measurement data-sets to develop our calibration and qualification routines to new heights in order to improve terminal throughput without sacrificing quality. 

CATR Commissioning and Development 

• Commission and run state-of-the-art Compact Antenna Test Range (CATR) systems 

• Run calibration and verification measurements of terminals as part of production 

• Run over-the-air development activity in the CATR for next-generation terminals 

• Maintain and develop MATLAB control scripts for the CATR system 

Antenna Calibration and Verification 

• Develop, calibrate, and verify the performance of the calibration system 

• Integrate calibration methodologies into system frameworks 

• Develop scripts to validate system functionality 

• Develop statistical confidence level indications for chamber calibrations 

Documentation and Reporting 

• Document calibration procedures, methodologies, and results for internal reference and regulatory compliance 

• Generate reports summarizing findings, including defects and performance metrics 

• Communicate effectively with stakeholders to convey results and recommendations. 

Requirements

QUALIFICATIONS, EXPERIENCE AND SKILLS:
