Role Description

We are seeking a Mechanical Engineering Intern to join our team. Our Manufacturing Engineering Operations team builds and supports the automation, test, and assembly processes behind Matterport's devices and product lines. Over an eight-week, in-person internship, you will own a single project from start to finish and present your results to the team at the end. The project will center on automation, test fixture design, or performance analysis for our hardware development, and will draw on both your mechanical engineering skills and your software and electrical instincts. That mechatronics blend is why this role matters: you should be comfortable working around a PCB, assembling electromechanical devices, sensors, and pulling data off hardware to analyze it.

The work will be scoped to your level but genuinely challenging. You will have a team of experienced engineers to guide you through our processes and procedures, dedicated mentors on your project, and an open, cross-functional culture where you can ask questions of anyone, from fellow interns to Sr. Staff engineers.

CoStar Group’s internship program provides hands‑on experience with enterprise-level projects. Interns work alongside full-time engineers, contributing to meaningful business initiatives and gaining exposure to core software engineering principles. Each intern is paired with a dedicated mentor to support technical development, career growth, and day‑to‑day learning throughout the program.

This position is located in Sunnyvale, CA.

What You Will Do

• Own one hardware project end to end, from concept through build and validation, and present it at the close of the internship.
• Design and assemble electromechanical hardware, working across all hardware sub-systems.
• Extract performance data from hardware systems and process it into useful, actionable results.
• Apply both mechanical and software/electrical engineering skills to solve real manufacturing or design problems.
• Work cross-functionally with experienced engineers and mentors, learning our processes, procedures, and product lines along the way.

Basic Qualifications

• Currently pursuing a bachelor’s degree or higher from an accredited, not-for-profit university or college in Mechanical Engineering or a comparable major. Must be planning to return to school following the completion of the Summer 2027 internship.
• Must have an expected graduation date of December 2027 - June 2028
• Minimum 3.0 cumulative GPA
• Available to participate in the full 10-week summer internship program and commit to a 40-hour work week throughout the internship.
• Working knowledge of mechatronics fundamentals: sensors, actuators, motor control, and basic electronics.
• Proficiency with a CAD package (SolidWorks, Fusion 360, or similar).
• Hands‑on aptitude: comfortable prototyping, wiring, assembling, and troubleshooting hardware.
• Comfort extracting and analyzing data with Python, MATLAB, or Excel, plus clear written and verbal communication.

Preferred Qualifications

• Working knowledge of mechatronics fundamentals: sensors, actuators, motor control, and basic electronics.
• Experience with microcontrollers or embedded platforms (Arduino, Raspberry Pi, or similar).
• Exposure to a manufacturing, production, or lab environment.
• Coursework or projects in mechanical design, robotics, automation, sensors, or precision motion systems.
• Interest in learning new technologies and building high-quality hardware.
• Demonstrated initiative and collaboration through academic, internship, extracurricular, or team-based experiences.
• Familiarity with Agile development practices.
• Exposure to AI, frameworks, or other technical tools through coursework, projects, internships, or personal learning.
• Experience building or contributing to technical projects, such as capstone projects, personal applications, research, or class-based hardware projects.
