At a glance

The Space Imaging team is seeking a Systems Engineer responsible for system architecture definition, trade analyses, and modeling/validating system performance for spaceborne EO/IR systems.
The role involves defining active EO/IR system architectures, performing radiometric performance modeling, and conducting laboratory, ground, and flight testing.
As needed, you will also lead small teams of engineers from concept ideation through system definition and development.

Define system architectures via detailed trade studies and analyses.
Adapt or derive physics-based models of sensor system performance and derive requirements based on those models.
Take ownership over the development of prototype sensor systems in a lab environment.
Support both laboratory-based and field-based experiments and demonstrations.
Engage technically with the hardware, software, and mission teams to define, integrate, and deliver high performance systems to our customers.
Validate models against laboratory and real-world data.
Coordinate and communicate with both external & internal stakeholders with varying degrees of technical background.

Proficiency in analytical toolchains or languages (e.g., MATLAB, Python)
Model development and validation in one or more domains relevant to remote sensing
Ability to decompose complex systems into functional parts, with clearly defined interfaces and requirements for each.
Experience in system design and development from initial concept through test and delivery to customer.
Strong laboratory skills (rapid prototyping, design of experiments) and familiarity with opto-electrical test and measurement equipment.
Willingness to travel to test sites, as needed.
Must be able to obtain and hold a U.S. security clearance.

Experience with industry standard EO/IR modeling software packages (e.g. MODTRAN, SPIRITS, AFSIM)
Prior experience working with space sensors and systems is highly desirable.
Knowledge of current and next-generation advanced sensing systems and platforms
Active and passive sensing domain experience (e.g., LiDAR, EO/IR, Radar)
Experience with laser systems, including opto-mechanical scanning and beam steering techniques.
Knowledge of electro-mechanical control systems, including their performance requirements and verification methodologies.
Experience with LiDAR/Radar signal processing techniques, and knowledge of their implementation on real-time embedded platforms (FPGA, MCU, etc.).
Space domain experience (architecting sensors for operation in space environments)
