Satellite imagery is a historically-scarce resource, whose adoption has been slowed by an unbalanced relationship between price and resolution. In theory, frequent, ultra high-resolution imagery of Earth has near infinite applications; in reality, only a sliver of that potential has been realized.

Albedo aims to be the catalyst in unlocking satellite imagery's latent potential, hoping to expand current applications and propel the discovery of new use cases. Whether our imagery is being used to reduce wildfire risk, assess the environmental impact of global forestry, contribute to timely 3D reconstructions of urban areas, or monitor carbon emissions from industrial power plants, our mission is to get better data into the hands of decision makers fast. We're modernizing how satellite imagery is used by providing near real-time access to our ultra-high resolution data.

What We're Up To: Albedo is developing a novel approach to the earth observation industry, both in space and with our business model. We are intentionally doing things differently by taking (calculated) risks, trying new things, and moving with speed. Our team believes satellite imagery is a valuable resource that should be made accessible, in every sense of the word. We are committed to our customers, ensuring that what we're building is what they want. We are playing at the edges of how traditional New Space technologies have been approached, and we want to shake up the industry as it stands today.

Who We're Looking For: Albedo is launching next-generation, ultra high-resolution imaging satellites to service a global audience through a modern, cloud-based product interface. In order to achieve this goal, we are looking for a team of people who are both passionate about our mission and are willing to put in the work to design, develop, and test an innovative earth observation concept in the commercial industry. The times ahead will be set in a fast-paced, often uncertain environment, but if you are hard-working, kind, and team-oriented, you can expect a rewarding and purposeful experience.

What You'll Do
  • Ensure that Albedo imagery is radiometrically calibrated, corrected, and uniform through end-to-end ownership from factory sensor measurements to on-orbit calibration methods to production ground software processing
  • Devise, simulate, implement, and refine on-orbit radiometric calibration approaches
  • Experiment with computer vision based methods to remove any residual image artifacts after rigorous calibration
  • Serve as primary technical expert in sensor device level interactions with established industry providers as we procure our space imaging sensors
  • Investigate novel approaches for flat-fielding and stabilizing Albedo's new thermal imagery

Ideal Skills and Experience
  • Successful experience taking factory calibration curve measurements for a device and translating those into non-uniformity correction tables and algorithms for operational usage, including accounting for test equipment uncertainty or guard-banding
  • Experience in using calibration methods other than on-board sources (also known as vicarious calibration) to produce or improve on radiometric calibration
  • Experience in interacting with a sensor provider at multiple levels (preferably detailed expert through to program manager), including reviewing, understanding, and guiding test data efforts
  • Familiarity with scanning imaging radiometric calibration artifacts, sometimes referred to as "streaking" and "banding", including both detector-response-knowledge-error-driven and spectral-response-flatness-control-driven causes of these artifacts
  • Familiarity with the process of absolute radiometric calibration (translating digital number back to irradiance, radiance, and surface reflectance)
  • Familiarity with how atmospheric conditions, attenuation, and haze affect radiometric response

  • Employee friendly equity compensation
  • Flexible working hours as a remote-first company
  • 4% direct matching 401k
  • Insurance: Medical, Vision, Dental, Mental Health
  • Parental leave and childcare coverage
  • 20 paid vacation days, yours from day one
  • 10 company holidays and unlimited sick days
  • $100 monthly wellness benefit
  • Three team retreats per year to build relationships in-person
