What is a test engineer internship?

A Test Engineer Internship is a temporary, hands-on role where interns assist in testing software or hardware products to ensure quality and functionality. Interns typically work with test plans, execute test cases, document results, and report bugs. They may use automated or manual testing techniques and collaborate with developers to improve product performance. This internship provides valuable experience in debugging, quality assurance, and test automation. It helps build technical and analytical skills essential for a career in software or hardware testing.

What types of projects or tasks can I expect to work on during a test engineer internship?

As a Test Engineer Intern, you'll typically be involved in tasks such as writing and executing test cases, identifying software bugs, and helping automate testing processes to improve efficiency. You may collaborate closely with software developers and other testers to ensure features function as intended and meet quality standards. Interns often participate in regular team meetings, contribute to test documentation, and may even help design new testing frameworks or scripts. This hands-on involvement helps you build both technical and teamwork skills, offering valuable exposure to real-world product development cycles.

What are the key skills and qualifications needed to thrive in the test engineer internship position, and why are they important?

To thrive as a Test Engineer Intern, you generally need a foundation in computer science or engineering, analytical problem-solving skills, and familiarity with software development and testing principles. Experience with test automation tools (such as Selenium or JUnit), scripting languages, and version control systems is often beneficial, though not always required. Strong attention to detail, effective communication skills, and a willingness to learn new technologies help candidates stand out. These combined skills ensure accurate testing, clear reporting, and a smooth integration within engineering teams, which are critical for delivering high-quality products.

Key responsibilities

  • Own and develop testing procedures to ensure hardware is qualified to fly and meets industry standards.

  • Design, qualify, and refine test processes, tooling, and test stands to support prototype development and high-volume production.

  • Assist design engineers in root cause analysis, guide new designs to qualification, and prototype components at the in-house R&D lab.


Job description

Amca is building Americaโ€™s new industrial base. Since the 1990s, our ability to build new aviation and military systems and maintain the ones we already have has eroded. Today, the gap between what the nation needs to produce and what it is capable of producing is the largest it has been in generations.

To help close that gap, Amca rapidly develops and manufactures new critical components and subsystems required to build and sustain the planes, military vehicles, and core infrastructure America needs. Today, we operate seven factories nationwide, including our advanced prototyping and testing headquarters in El Segundo, and deliver avionics, hydraulic, and electrical components for platforms such as the F-35, F-16, F/A-18, 737MAX, 787, A320neo, A321, Mk-48, and M1 Abrams.

Overview:

The Mechanical Test Engineering role is responsible for owning the testing procedures used to prove new designs are fit to fly. You will serve as the extreme owner for qualification tests that are run at our in-house R&D shop during hardware development, and the acceptance testing that is run at our factories to ensure every unit produced is high quality and functional. Your day will consist of developing tooling, bringing new state-of-the-art production assets online, and assisting design engineers in root cause analysis for qualification campaigns.

Responsibilities:
  • Develop test methodology in accordance with industry standards to ensure all hardware is qualified to fly
  • Develop, qualify, and refine test processes to bring products from prototype to high-volume production
  • Trade purchasing commercial test capabilities off the shelf against designing and developing the capabilities in house
  • Act as the extreme owner of the test stands, whether that is designing new test stands or developing procedures and criteria for existing infrastructure
  • Ideate and implement tooling and custom test solutions, enabling high-quality build of Amca hardware
  • Identify, plan, and execute capital equipment, machine, and layout upgrades to meet changing needs
  • Partner with engineering and production teams to generate ideas, designs, and improvements for current and next-generation vehicles
  • Assist design engineers in guiding new designs from concepts to qualified, production-capable aerospace components
  • Prototype new components at our in-house R&D lab. You will be expected to be intimately involved with any prototype development
  • Set the standard for rigorous component design and qualification testing. As a member of an early-stage startup, you will be integral in defining company design and testing policies
Basic Qualifications:
  • Bachelor's or advanced degree in aerospace engineering, manufacturing engineering, materials engineering, mechanical engineering or engineering physics
  • 1+ years of engineering experience in manufacturing, design, test, or development (internship and project team experience is applicable)
  • Strong understanding of engineering first principles, specifically with regards to thermodynamics, fluid dynamics, and solid mechanics
Preferred Skills and Experience:
  • Strong interpersonal and collaborative skills, enthusiasm for problem solving, and desire to optimize modern aerospace production and design processes
  • 2+ years of professional experience in the field of aerospace/mechanical engineering
  • 2+ years of experience with GD&T concepts
  • Strong project management skills and effective communication of technical concepts across multi-disciplinary teams
  • Experience with the building and testing of fluid and/or electrical systems
  • Experience with the build and test of pneumatic, hydraulic, and structural assemblies
  • Experience with scientific computer science languages (Python, MATLAB, or similar)
  • Experience with Siemens NX or other similar CAD package
  • Experience using test instrumentation and control components (e.g. pressure transducers, thermocouples, resistance temperature detectors, relays, solenoid valves, etc.)
Additional Requirements:
  • Travel to vendors and other Amca sites as needed
  • Able to work flexible hours and occasional weekend support as needed
