At Array Labs, we are building the world's most advanced satellite radar constellation to create a high-resolution 3D digital twin of the Earth. Our mission is to provide "lidar-like" 3D data and imagery from space, serving critical applications for both commercial and defense customers. This is a deep tech challenge in the truest sense. We're solving complex problems that span hardware, software, and data—from designing satellite systems for the harshness of space to building the massive "data factory" that turns raw sensor data into beautiful 3D products. We are looking for first-principles engineers who want to build, deploy, and scale a one-of-a-kind, vertically-integrated system from the ground up. As a radar algorithms engineer you will develop, deploy, and scale innovative 3D reconstruction algorithms and processing techniques for this unique radar imaging system. In addition to working closely with the rest of the software team, you will be collaborating with the hardware and product teams to rapidly advance image formation techniques from concept to a cloud-based imagery production pipeline.

  • Develop synthetic aperture radar algorithms to create high-quality 3D data-products. These can take inspiration from techniques in tomography, interferometry, radargrammetry, as well as computer vision algorithms.
  • Work closely with the rest of the software team to implement and deploy efficient algorithms in our cloud-based image production pipeline
  • Create tools for predicting the performance of 3D reconstruction algorithms based on image collection geometry
  • Collaborate with the product team to understand customer use-cases and translate needs into system-level requirements.
  • Generate test plans and methods to validate product quality and ensure it meets end-user expectations
  • Bachelor’s degree in electrical engineering, physics, computer science, or related field
  • Experience in SAR digital signal processing and algorithm development
  • Excellent teamwork and communication skills
  • Learn new concepts rapidly, completely, and in a self-directed manner
  • High levels of self-motivation and personal accountability
  • Ability to work in a fast-paced environment under significant time constraints
  • Proficiency in Python, C/C++, or MATLAB
  • Advanced degree with emphasis in radar image formation
  • Familiarity with SAR image formation algorithms
  • Familiarity with SAR collection modes and motion compensation concepts
  • Experience deploying radar algorithms into production pipelines
  • Familiarity with modern software development practices (version control, code review, continuous integration, etc)
  • Familiarity with SAR collection geometries and implications (crossing node interferometry, multi-baseline interferometry)
  • Familiarity with SAR interferogram processing
  • Familiarity with tomographic aspects of SAR and related concepts such as holographic principles, critical baseline, etc.
  • Familiarity with multi-dimensional inverse SAR and related optimization methods
