Job Description

YOUR MISSION

We are seeking a highly skilled Developmental Test Technician with deep expertise in fluid systems to support hands-on test operations at our test site facilities. This is a test site-based role requiring regular travel between our Long Beach headquarters and remote test locations. You will be on the floor every day—assembling complex fluid systems, configuring test rigs, operating ground support equipment, and executing test campaigns for propulsion and spacecraft hardware. Reporting to the Developmental Test Technician Lead, you'll work alongside propulsion and fluids test engineers to deliver safe, precise, high-quality test operations in a fast-paced, build-it-from-scratch startup environment.

RESPONSIBILITIES

• Perform hands-on assembly, integration, and configuration of fluid system test articles, test rigs, and ground support equipment for propulsion and fluids test campaigns.

• Execute fluid system test operations including propellant loading, pressurization, leak checks, proof tests, and functional/performance tests under the direction of test engineers.

• Fabricate, modify, and repair fluid system hardware using precision hand tools, power tools, and tube bending equipment. Work with various fittings including NPT, AN, MS, Swagelok, VCR, and medium-pressure cone fittings.

• Operate, maintain, and troubleshoot fluid GSE including fill/drain equipment, pressure regulators, purge systems, cryogenic systems, and test instrumentation.

• Support propellant handling and hazardous fluid operations in strict accordance with site safety procedures and range safety requirements.

• Perform hardware inspections and documentation, flagging non-conformances and ensuring all materials meet cleanliness standards including clean-for-oxygen-service requirements.

• Maintain tooling, GSE, and consumables readiness including inventory tracking and calibration management.

• Support anomaly investigations through hands-on observations, hardware teardown, and documentation of as-found conditions.

• Travel regularly between Long Beach headquarters and test sites to support test campaigns and maintain test site readiness.

BASIC QUALIFICATIONS

• Technical degree, certification, vocational training, or equivalent hands-on experience (5+ years) in fluid systems, propulsion systems, pipefitting, or mechanical trades.

• Extensive hands-on experience with fluid system assembly, high-pressure testing, leak testing, and pressure proof operations.

• Demonstrated expertise working with hazardous fluid systems including cryogenics, hypergolics, and high-pressure systems (>3,000 psi).

• Proficiency reading and working from engineering drawings, P&IDs, and work instructions.

• Strong mechanical aptitude with experience using hand tools, power tools, tube benders, and precision measurement tools.

• Understanding of safety compliance and OSHA requirements for fluid and pressure system operations.

• Willingness to travel/support between sites including test sites to achieve company milestones.

• Physical ability to lift up to 50 lbs, work in confined spaces, and perform extended standing, bending, and reaching tasks.

• U.S. Citizenship required due to government contracts.

PREFERRED QUALIFICATIONS

• 8+ years of aerospace or defense test operations experience with propulsion or high-performance fluid systems.

• Direct experience with propellant loading operations including fueling, defueling, and purge procedures.

• Experience with structural test operations including proof testing and hydraulic systems.

• Background in data acquisition systems and test instrumentation setup.

• Welding certifications (TIG, orbital welding) for stainless steel, Inconel, or titanium.

• Experience with vacuum systems and clean-for-oxygen-service environments.

• Prior experience at development or propulsion test facilities.

• Leadership experience mentoring junior technicians or leading work teams.

• Active DoD clearance or ability to obtain one.

• Heavy equipment certifications (forklift, boom lift, crane/rigging).

COMPENSATION AND BENEFITS

Base Salary:

• Technician Level 1: $32-41/hr
• Technician Level 2: $40-55/hr
• Technician Level 3: $45-60/hr
• Senior Technician: $55-70/hr

Equity + Benefits including Health, Dental, Vision, HRA/HSA options, PTO and paid holidays, 401K, Parental Leave
