Job summary

FedWriters, Inc. in Norman, Oklahoma is seeking an MLOS Development Engineer to support the NSSL Microwave Line-of-Sight project.

You will advance a hardware-level system to demonstrate RF phase shifts can estimate relative humidity, working with RF signals, circuits, and enclosure design. The role requires hands-on hardware work, collaboration with NOAA/NSSL scientists, and software development to calculate humidity from phase data, plus documentation and presentations for AMS guidelines and

Qualifications

• BA/BS in Electrical Engineering or related field.
• 6+ years of full-time electrical engineering experience.

Responsibilities

• Continue development of the MLOS proof-of-concept system to demonstrate feasibility of using RF transmissions to retrieve relative humidity estimations
• Collaborate with NOAA/NSSL scientists and engineers to evaluate the existing project's circuitry, parts, and test plans
• Install and configure test equipment at the Norman, Oklahoma site
• Perform experiments to assess the viability of using the system to derive humidity measurements from RF phase shift data, including collecting data across a broad range of operating conditions and humidities, as conditions permit
• Use experimental results to refine the experimental design, equipment, and/or retrieval scheme to improve humidity detection, including collaborating on mechanical or electrical solution design (e.g., phase-locked oscillators, enclosure climate control, feed horn replacement, transmitter power adjustments) and testing as applicable
• Evaluate whether the measured phase difference can be digitized and used in an algorithm to obtain reliable relative humidity measurements
• Collaborate with NSSL scientists, engineers, and external partners to validate against other operational and/or experimental observations
• Assist NSSL staff in deploying other research systems, as appropriate for validation
• Create and maintain software that uses digitized phase shift data to calculate relative humidity and is capable of reporting humidity data in real time, if applicable
• Provide technical documentation (e.g., schematics, code repositories, test reports) for development activities
• Prepare quarterly reports of status
• Write a brief report following AMS guidelines and prepare a conference-style presentation; present to project stakeholders and at a national or international conference if possible
