Remote Sensing Engineer

The Remote Sensing Engineer will play a central role in advanced Earth-observing microwave remote sensing missions developed at Spire Global, providing technical leadership for the calibration, validation, and scientific exploitation of spaceborne microwave radiometers. This position spans responsibility for payload performance, RF engineering, ground processing of instrument data to deliver to our global Numerical Weather Prediction (NWP) customers and in-orbit calibration, and scientific support for atmospheric retrieval algorithms. This is a pivotal role that is key to Spire building the world's first hyperspectral microwave and multi-sensor commercial constellation to measure temperature, water vapour and precipitation at spatial and temporal scales beyond the current state of the art.

Key Responsibilities

• Lead and oversee in-orbit calibration and validation of our microwave sounding instruments, including design and implementation of in orbit calibration, radiative transfer modelling, end-to-end testing, and on-orbit performance assessment.
• Maintain scientific code base for ground processing of microwave sensor observation data for operational delivery to end users
• Lead algorithmic development for atmospheric temperature, humidity and precipitation retrievals from brightness temperature measurements, including radiative transfer modelling and uncertainty estimation.
• Support trade studies and requirement definition for future missions and collaborate with multi-disciplinary engineering team and end users to define and deliver next generation sensing capabilities.
• Develop, improve, and maintain calibration methodologies, including cross-calibration with reference targets (cold space, onboard blackbody), and support radiometer precision traceability.
• Analyse and visualise large-scale Earth observation datasets, applying physical principles and advanced coding (Python libraries including numpy, pandas, etc) to extract scientific and engineering insights from complex multi-channel microwave data.
• Document and communicate results via technical reports, scientific publications, and presentations at international conferences and internal forums.
• Collaborate with multidisciplinary teams, including RF engineers, scientists, and software developers, to deliver mission objectives under demanding operational timelines.
• Mentor junior staff and contribute to continuous improvement of instrumentation and measurement techniques.
