Summer Lab Intern information

What is a summer lab intern?

Summer Lab Interns are typically students or recent graduates who work temporarily in a laboratory setting during the summer months. They assist with scientific research, experiments, and data collection under the guidance of experienced lab staff. These internships provide hands-on experience and exposure to laboratory techniques, often helping interns decide on future career paths in science. Responsibilities can vary depending on the lab, but usually include maintaining equipment, recording observations, and supporting ongoing research projects.

What types of projects and responsibilities can a summer lab intern expect to work on during their internship?

As a Summer Lab Intern, you can expect to participate in a variety of hands-on projects that support ongoing research within the lab. Your daily tasks may include preparing samples, conducting experiments under supervision, collecting and analyzing data, and assisting with equipment maintenance. Collaboration is key, as you’ll often work closely with graduate students, technicians, and principal investigators who will guide your learning and help you develop essential lab skills. Interns are usually encouraged to ask questions, contribute to team meetings, and may have opportunities to present their findings. This role offers a great foundation for understanding real-world research environments and can open doors for future academic or professional pursuits in science.

What are the key skills and qualifications needed to thrive as a summer lab intern, and why are they important?

To thrive as a Summer Lab Intern, you generally need foundational knowledge in science or engineering, strong analytical skills, and enrollment in a relevant degree program. Familiarity with laboratory equipment, safety protocols, and software tools like Excel or data analysis platforms is often required. Attention to detail, strong communication, and eagerness to learn are key soft skills that help interns stand out. These skills and qualities ensure safe, accurate experimentation, effective teamwork, and meaningful contributions to ongoing research projects.

What is the difference between Summer Lab Intern vs Summer Research Assistant?

AspectSummer Lab InternSummer Research Assistant
Required CredentialsTypically undergraduate student, some labs prefer coursework in relevant science fieldsUsually undergraduate or graduate students with some research experience
Work EnvironmentLaboratory setting, assisting with experiments and data collectionResearch projects, often more independent, supporting senior researchers
Employer & Industry UsageUniversities, research institutes, biotech companiesUniversities, research labs, government agencies

The Summer Lab Intern role generally targets undergraduate students gaining initial research experience, focusing on assisting with lab tasks. The Summer Research Assistant position often involves more independent work and is suitable for students with some prior research background. Both roles are valuable for building research skills but differ in responsibilities and experience level.

Job description

Test Engineering Intern
Mequon, WI | Department: Engineering | Reports to: Test Lab Supervisor
About Hayes Performance Systems:
Hayes Performance Systems is a trusted leader in precision engineering and manufacturing, serving industries like powersports, cycling, agriculture, construction, and government. Since 1946, we've built high-performance braking and suspension systems known worldwide for their quality and reliability. In 2023, we expanded through the acquisition of ACI Industries, strengthening our capabilities in complex machining and precision assembly.
At Hayes, we don't just make parts - we make performance possible. We value teamwork, problem-solving, and continuous improvement, and we're looking for people who want to grow with us.
Why You'll Love Working Here:
  • Flexible hours to support school schedules
  • Mentorship from experienced engineers and technicians
  • Holiday Parties and Employee Events throughout the year
  • A supportive, team-focused culture where your ideas are valued and your work makes an impact

The Opportunity:
We're hiring a Test Engineering Intern to join our engineering team. In this role, you'll get hands-on with real products, real testing, and real engineering challenges. You'll support our engineers in the test lab and see firsthand how designs are validated and improved before going into production.
What You'll Do:
Here's what your day-today might look like:
  • Help set up and run product tests in the lab
  • Work with engineers to gather meaningful test data
  • Record test procedures, results, photos, and videos
  • Turn results into clear reports, graphs, and tables
  • Support design validation and performance testing
  • Assist with troubleshooting and test improvements
  • Share results and observations with the engineering team
  • Help make our testing processes even better over time

What You Bring:
We're looking for someone who is:
  • Currently pursuing a bachelor's degree in engineering (junior standing preferred)
  • Available part-time during the school year (10-20 hours/week) and full-time in the summer
  • Curious, hands-on, and excited to learn how things work
  • Comfortable using Word and Excel (we'll teach you the rest)
  • Interested in lab work, testing, or CAD (experience is a plus, not a must)
  • Organized, reliable, and a good communicator
  • Able to commute to our Mequon, WI location

You'll thrive in this role if you enjoy learning by doing, asking questions, and working with a team that likes to build, test, and improve real products.
Ready to Build Performance?
