Senior Test Engineer

Singularity is an aerospace and defense startup headquartered in Gardena, CA. Our founding team hails from SpaceX, Anduril, and Lockheed Martin, and we are backed by Joint Staff-level military leadership and several Silicon Valley firms. Our first product is a low-cost air defense system built for immediate deployment worldwide. With a world-class business development and leadership team already in place, we are well positioned to capitalize on already overwhelming demand.

Role Overview

As a Test Engineer in Singularity’s Test Engineering team, you will design, build, and own test infrastructure for our defense products. You will develop end-to-end test plans - from concept to data analysis - for components and subsystems spanning shock and vibe, environmental, performance, electrical and mechanical systems.

You will help develop and document our testing best practices, requirements, and workflows to enable rapid iteration and high-quality data.

You will collaborate with cross-functional teams to ensure that prototype, development, and qualification hardware is designed with respect to a test plan that validates critical features and performance parameters. You will design, validate, and maintain test setups to ensure the required precision and accuracy.

Key Responsibilities

• Architect, build, and employ test stands and processes for validating design hardware

• Develop comprehensive test plans and protocols: instrumentation, execution steps, pass/fail criteria, and data analysis workflows

• Build test schedules and ensure alignment with development and business needs

• Lead test design and readiness reviews and communicate approach and results with stakeholders

• Validate measurement precision and accuracy; procure or design specialized fixtures and sensors as needed

• Create schematics and CAD models of test setups and facilities

• Define standard processes and workflows for prototype, qualification, and production-grade testing

• Provide subject matter expertise on test methods, including mentoring teammates

• Participate in root cause investigations and implement corrective actions to prevent repeat failure

Team Development

• Help build the team of quality-focused engineers and technicians, fostering a culture of technical excellence, teamwork, and accountability.

• Identify and resolve technical challenges, implementing corrective actions and continuous improvement initiatives.

• Train and upskill technicians on new processes, tools, and industry best practices.

• Performs other related duties as assigned, for the purpose of ensuring an efficient and effective work environment

• You take ownership and drive continuous improvement without waiting for permission

Basic Qualifications

• 5+ years of hands-on test engineering experience
• Experience designing assemblies and test fixtures using CAD
• Experience with LabVIEW, Simulink, or similar test software
• Experience integrating and using test instrumentation (pressure transducers, thermocouples, strain gauges, relays, solenoid valves, etc.)

Preferred Skills & Experience

• Master’s degree or higher in mechanical or aerospace engineering
• 8+ years of hands-on test engineering experience
• Experience designing and building test rigs and executing thermal and mechanical tests
• Experience setting up testing software resources and establishing best practices with LabVIEW, Simulink, or similar test software
• Experience testing military products to MIL-STD requirements
• Experience in mechanical, durability, or materials testing
• Leadership experience on a project or research team
• Strong project management and cross-disciplinary communication skills
• Demonstrated track record of high-impact technical contributions
• Experience with part inspection technologies (micrometers, CMM, white light scanning, etc.)
• Knowledge of PLM, ERP, and related manufacturing systems
• Strong Python or general programming experience
