## Job description

Manufacturing Integration and Test Engineer

## About Epirus

Epirus is a high-growth technology company dedicated to overcoming the asymmetric challenges inherent to the future of national security. Epirus' flagship product, Leonidas, is a software-defined system built using intelligent power management techniques which allow power-hungry systems to do more with less.

Position Summary

This is an exciting role in an innovative, high-growth defense technology company. The ideal candidate for the position is someone who has experience with troubleshooting and sustaining automated test benches and special test equipment for high-performance production hardware as well as troubleshooting systems at various functional testing phases. This role will be a part of our manufacturing engineering team, but will serve as the connective tissue between hardware, electrical, and software—taking subsystems from individual validation through full system integration and verification. This individual will help define test strategies and procedure, build testing fixtures, ensure product quality through validation, and serve as the technical escalation point for production technicians during test execution. This is an on-site role.

Responsibilities:

- Support final functional testing of fully integrated electro-mechanical assemblies to verify performance against engineering and customer specifications
- Develop and document test procedures, work instructions, and test fixtures for new and existing products
- Troubleshoot and resolve test failures, providing hands-on technical support to production technicians during testing operations
- Analyze test data and failure trends to identify root causes and drive corrective actions
- Collaborate with design, manufacturing, and quality engineering teams to address product or process issues identified during testing
- Develop and execute test plans, test procedures, and acceptance criteria derived from system requirements
- Develop and maintain test equipment, fixtures, and automated test systems; calibrate and maintain test instrumentation
- Identify and implement process improvements to increase test efficiency, throughput, and reliability
- Train technicians on new or revised test procedures and equipment
- Participate in root cause / corrective action (RCCA) investigations for field or production failures

Basic Qualifications:

- BS or MS degree in Electrical Engineering, Mechanical Engineering, or any related field
- Minimum 2 years of experience in Test Engineering or an advanced degree without experience

Preferred Skills and Experience:

- 5 years of experience in test engineering
- Experience in aerospace, defense, or high-reliability industries
- Understanding of RF, power, and digital engineering concepts
- Experience working with RF test and measurement equipment such as: VNAs, Spectrum Analyzers, High-Speed Oscilloscopes, Power Meters, AutoCal Modules, Power Amplifiers
- Comfortable with object-oriented programming such as C++, C, Python
- Experience scaling production from prototype to volume
- Familiarity with regulatory environments (ITAR, AS9100, ISO)
- Familiarity with electrical test and measurement equipment such as multimeters, oscilloscopes, function generators, power supplies
- Previous experience with environmental acceptance and qualification test plans
- Strong documentation skills to track and analyze root cause of non-conforming hardware
- Strong test plan and requirements writing skills
- Good written and oral communication skills
- Collaborative; capable of working across all levels of the organization
- Organized; comfortable working in a fast-paced, ever-changing environment
- Ability to cover the entire test system lifecycle independently
