Job description

Advanced Reentry Technologies

Who We Are:

Inversion is an aerospace and defense company pioneering advanced reentry technology to enable next-generation capabilities from space. By combining high-performance materials, precision aerodynamics, and mission-driven autonomy, Inversion is transforming reentry into an operational capability for an entirely new class of missions.

The company’s highly maneuverable reentry spacecraft, Arc, is designed for rapid global cargo delivery, hypersonic testing, and other national security missions that require precise, controlled flight through the atmosphere. Arc creates an entirely new transportation domain, unlocking unprecedented speed and global reach.

Headquartered in Los Angeles, Inversion designs, manufactures, and integrates its spacecraft under one roof, enabling the company to move rapidly from concept to flight. The company is backed by leading investors including Y Combinator, Spark Capital, and Lockheed Martin Ventures, with customers across the U.S. government and commercial space industry.

Position Overview:

As a Senior Test Engineer at Inversion, you will own the planning and execution of critical mechanical test campaign s for one of the most capable reentry vehicles ever developed. You’ll lead testing from early component and subsystem development through integrated demonstration, working closely with design, analysis, manufacturing, and external test partners to retire risk and validate system performance.

This is a unique opportunity to build and lead high-consequence mechanical test campaign s for a new aerospace vehicle from early development through qualification and production. You will be a key member of the Mechanical team, reporting to the Director of Mechanical.

Key Responsibilities:

• Own the planning and execution of component, subsystem, and system-level test campaigns supporting deployment and separation mechanism development.
• Lead complex test campaigns to demonstrate system performance under representative environments.
• Develop test plans, procedures, success criteria, and test readiness documentation for mechanical development and validation activities.
• Coordinate closely with external test facilities and vendors to define test requirements, facility interfaces, schedules, constraints, and execution plans.
• Design and develop test fixtures, adapters, support equipment, and other GSE required to safely and effectively execute testing.
• Partner with structures, mechanisms, dynamics, and manufacturing engineers to ensure test articles, fixtures, and instrumentation support key technical objectives.
• Define instrumentation and data collection needs in collaboration with internal and external partners to ensure test results can validate performance and inform model correlation.
• Drive test campaign logistics including hardware readiness, facility integration, procedural development, configuration tracking, and execution coordination.
• Lead troubleshooting and issue resolution during test preparation and execution, and drive rapid turnaround on test learnings into follow-on hardware or procedures.
• Author test reports and communicate results, risks, and recommended next steps in design reviews and cross-functional program forums.

Required Qualifications:

• Bachelor's degree in Aerospace Engineering, Mechanical Engineering, or a related field, or equivalent technical experience.
• Typically 5+ years of professional experience in development testing, qualification testing, or mechanical system test engineering for aerospace, defense, or similarly demanding applications.
• Experience developing and executing component and subsystem-level test campaigns for mechanical hardware.
• Experience writing test plans, procedures, test readiness documentation, and post-test reports.
• Experience designing test fixtures, adapters, tooling, or ground support equipment for mechanical or aerospace hardware.
• Strong understanding of mechanical systems, including structures, mechanisms, interfaces, and hardware integration.
• Experience coordinating with external test facilities, vendors, or suppliers to execute complex test programs.
• Demonstrated ability to work cross-functionally with design, analysis, manufacturing, and program teams to drive tests from concept through execution.
• Demonstrated excellent verbal and written communication skills.
• Proven ability to work effectively in a fast-paced environment.
• Must have the ability to obtain and maintain a U.S. government Secret/Top Secret security clearance.

Desired Qualifications:

• Master's degree in Aerospace Engineering, Mechanical Engineering, or a related field, or equivalent experience.
• Experience owning complex mechanism, deployment, or separation system test campaigns from early development through integrated demonstration.
• Experience testing hardware in high-dynamic, high-shock, vibration, or transient mechanical environments.
• Experience supporting correlation of test results to loads, structural dynamics, or multibody dynamics models.Experience developing and executing tests for qualified flight hardware.
• Experience with instrumentation planning, sensor selection, data acquisition coordination, and extraction of design-relevant test data.
• Experience supporting rapid hardware iteration and test-driven development in a hardware-rich environment.
• Experience working with external government, commercial, or specialized test facilities.
• Experience using CAD tools to design test fixtures, support equipment, or integration hardware.
