About this role
About Us
Array Labs builds advanced radar systems to help humanity understand and respond to changes across the physical world.
We're launching a coordinated fleet of radar satellites to create a high-resolution 3D map of the Earth, updated in real time, enabling faster, smarter decision-making for government and commercial organizations supporting disaster response, infrastructure resilience, and mission-critical geopolitical intelligence.
We design and build our satellites end-to-end, producing the world's most advanced earth observation satellites. Our fleet will deliver unprecedented levels of accuracy, coverage, and responsiveness to power critical insights precisely where they're needed most.
Responsibilities
- Design mechanical structures and assemblies for SAR imaging payloads and satellite subsystems
- Create 3D models and detailed manufacturing drawings in SolidWorks
- Perform structural analysis to verify designs meet launch load and stiffness requirements
- Conduct tolerance stack-up analysis to ensure proper fit and function across integrated assemblies
- Support spacecraft environmental verification including vibration, thermal-vacuum, and EMI/EMC testing to meet SpaceX launch acceptance requirements
- Collaborate with RF, electrical, and systems engineers to integrate the SAR payload with bus subsystems
- Coordinate with vendors and machine shops on procurement, fabrication, and delivery of flight-quality components
- Develop and maintain design documentation including drawings, design guides, and Interface Control Documents (ICDs)
- Perform hands-on Assembly, Integration, and Testing (AI&T) of prototype and flight hardware
Basic Qualifications
- Bachelor's degree in mechanical engineering
- 7+ years of experience in mechanical design and analysis, preferably in aerospace or spacecraft systems
- Proficiency in SolidWorks for 3D modeling, drawing creation, and simulation
- Experience with structural FEA for launch load verification (quasi-static, random vibration, sine burst)
- Strong understanding of GD&T and tolerance stack-up analysis
- Experience creating manufacturing drawings for machined and fabricated parts
- Experience and desire to work in multiple areas (jack of all trades design, fab, drawing, inspection, etc...)
- Versatile engineering skill set with a strong desire to engage in all phases of hardware creation (design, fabrication, drafting, and inspection)
Preferred Skills & Experience
- Experience with spacecraft or payload environmental verification (vibration, thermal-vacuum testing)
- Some proficiency with tools for thermal modeling and analysis
- Experience correlating structural/thermal models to test data, especially through scripting or automation (Python or similar)
- Knowledge of spacecraft thermal control techniques (MLI, heaters, radiators, thermal straps)
- Experience interfacing with launch vehicle providers on payload integration requirements
- Hands-on AI&T experience with flight hardware, avionics, and flight harnessing
