About the role

Define standard processes and workflows for prototype, qualification, and production-grade testing
Provide subject matter expertise on test methods, including mentoring teammates

Responsibilities

Architect, build, and employ bespoke test stands and rigs for heat pipe components and assemblies
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
Participate in root cause investigations and implement corrective actions to prevent repeat failure
As a Test Engineer in Antares' Test Engineering team, you will design, build, and own test infrastructure for our R1 microreactor.
You will develop end-to-end test plans - from concept to data analysis - for components and subsystems spanning heat rejection, power distribution, thermal management, and mechanical systems.
You will help develop and document our testing best practices, requirements, and workflows to enable rapid iteration and high-quality data.

Requirements

Bachelor's degree in physics or an engineering discipline
2+ years of hands-on test engineering experience
Experience designing assemblies and test fixtures using CAD
Experience integrating and using test instrumentation (pressure transducers, thermocouples, strain gauges, relays, solenoid valves, etc.)
Ability to lift 25 lbs
Think probabilistically and then take action. "If you want to be certain, then you are apt to be obsolete." Over-optimizing the components often degrades the system

Skills

Master's degree or higher in mechanical or aerospace engineering
Experience with LabVIEW, Simulink, or similar test software
Experience testing thermal management or heat-rejection systems, or vacuum-relevant components
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
