Test Automation Engineer Intern information

What is a test automation engineer intern?

Test Automation Engineer Interns are entry-level professionals or students who assist in designing, developing, and executing automated tests for software applications under the supervision of experienced engineers. Their main role is to ensure that software products function correctly by using automation tools to identify bugs and verify code quality. Interns typically work with scripting languages, learn about different testing frameworks, and gain hands-on experience in the software development lifecycle. This position is ideal for those interested in starting a career in software quality assurance and automation engineering.

What types of projects and responsibilities can a test automation engineer intern expect during their internship?

As a Test Automation Engineer Intern, you'll typically work on creating, executing, and maintaining automated test scripts for software applications under the guidance of senior team members. You'll collaborate closely with developers and QA professionals to understand requirements, identify test cases, and ensure thorough test coverage. Interns often participate in daily stand-ups, code reviews, and may assist in troubleshooting issues discovered during automated testing. This role provides hands-on experience with popular automation tools and frameworks, helping build foundational skills for a career in software quality assurance.

What is the difference between Test Automation Engineer Intern vs QA Tester Intern?

AspectTest Automation Engineer InternQA Tester Intern
Primary FocusDeveloping and maintaining automated test scriptsExecuting manual and automated tests to identify bugs
Skills RequiredProgramming, scripting, automation toolsTesting methodologies, attention to detail
Work EnvironmentCollaborates with developers, uses automation frameworksWorks closely with QA teams, performs manual testing
CertificationsBasic knowledge of testing tools, programming certificationsTesting certifications like ISTQB beneficial

In summary, Test Automation Engineer Interns focus on creating automated tests using programming skills, while QA Tester Interns primarily perform manual testing and basic automation. Both roles are essential in quality assurance but differ in technical depth and responsibilities.

What are the key skills and qualifications needed to thrive as a test automation engineer intern, and why are they important?

To thrive as a Test Automation Engineer Intern, you need a solid understanding of programming concepts, software testing methodologies, and knowledge of at least one scripting language, often backed by progress toward a relevant degree. Familiarity with automation tools like Selenium, JUnit, or TestNG, and experience with version control systems such as Git, are typically expected. Attention to detail, problem-solving skills, and effective communication make candidates stand out in this role. These abilities ensure efficient test coverage, fast identification of software issues, and productive teamwork in the software development lifecycle.

Job description

Test Automation Engineering Intern 

Redwood Energy is building some of the fastest, lowest-cost energy storage in the U.S. from both new battery modules and second-life EV packs. Second-life hardware arrives with a history - different chemistries, capacities, and states of health - and every unit has to be proven safe and reliable before it ships. That proof comes from test: the automated systems that exercise the firmware and electronics inside our products and decide whether they're ready for the field. 

Our test engineering team builds those systems - the test stands on the production floor, the hardware-in-the-loop benches that validate firmware releases, and the CI pipelines that tie them together. As a Test Automation Engineering Intern, you'll work alongside our engineers building the next generation of this test capability. You'll write Python that drives real instruments and real battery hardware, help bring up new test stands from the bench up, and debug failures where the root cause could live in the test code, the firmware, or the unit under test. This is a great opportunity to apply what you've learned in coursework to production test systems, with mentorship from experienced engineers along the way. 

Responsibilities will include:  

  • Test Automation: Write and maintain Python test automation for firmware and hardware validation, using pytest and our internal test frameworks. 
  • Instrument Control: Develop drivers and tooling for programmable power supplies, electronic loads, data acquisition, and switching hardware over protocols like SCPI, CAN, and Modbus. 
  • Test Stand Bring-Up: Help bring up new test stands - from fixtures and wiring through the software that sequences them - as we expand our validation capability. 
  • System Debugging: Investigate real failures on real equipment, using CAN traces, instrument logs, and bench tools to determine whether the fault lies in the test code, the fixture, or the unit under test. 
  • Continuous Integration: Add regression coverage to our CI pipelines so firmware changes are validated automatically rather than by hand. 
  • Documentation & Process: Contribute to documentation and test processes that support taking test systems from prototype toward production. 
  • You'll own a scoped project end to end and present your results to the engineering team at the close of the internship. 

Desired Qualifications: 

  • Background: Currently pursuing a BS or MS in Electrical Engineering, Computer Engineering, Computer Science, Mechatronics, or a related field. 
  •  Programming Foundations: Working proficiency in Python, including comfort reading and modifying a codebase you did not write. 
  • Testing Experience: Experience writing automated tests with pytest or a comparable framework, from coursework, projects, or prior internships. 
  • Version Control: Experience with Git and a pull-request-based development workflow. 
  • EE Fundamentals: Solid grasp of circuit basics - voltage, current, resistance, and power, and how they relate - sufficient to predict what a measurement should read and recognize when it doesn't. 
  • Hardware Fundamentals: Able to read a schematic, wiring diagram, or datasheet and act on it; hands-on experience working safely around energized equipment - power supplies, loads, or battery hardware - from lab work, projects, or prior internships. 
  • Communication Protocols: Familiarity with CAN, Modbus, SCPI, or other instrument and industrial protocols is a plus, even if only from classwork or personal projects. 
  • Linux: Familiarity with the Linux command line is a plus. 
  • Curiosity & Rigor: A safety-conscious mindset, strong attention to detail, and eagerness to learn how production test systems are built. Prior industry or energy storage experience is not expected.
