What are the responsibilities and job description for the Mechanical Engineer position at Array Labs?
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.
- 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
- Bachelor's degree in mechanical engineering
- 3 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)
- 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
Compensation & Benefits
Our hiring and compensation strategy is simple: find uncommonly good people and pay them uncommonly well.
We offer high flexibility between salary and equity-based compensation. Final candidates can choose from three compensation mixes: low, medium, or high equity. Equity is a significant component of total compensation, and we aim to provide meaningful ownership for this role.
