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

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)

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
