Mechanical Engineering Intern (PICO) - 2026 Summer (MS)

Job Description:

About Team We are looking for a Mechanical Engineering Intern to support early-stage AR hardware prototyping. This role focuses on designing and building non-final, experimental mechanical systems that enable feature exploration, system validation, and algorithm testing for AR devices. The work emphasizes rapid iteration and hands-on prototyping, rather than development of production-ready products. We are looking for talented individuals to join us for an internship in 2026. Internships at ByteDance aim to offer students industry exposure and hands-on experience. Watch your ambitions become reality as your inspiration brings infinite opportunities at ByteDance. Internships at ByteDance aim to provide students with hands-on experience in developing fundamental skills and exploring potential career paths. A vibrant blend of social events and enriching development workshops will be available for you to explore. Here, you will utilize your knowledge in real-world scenarios while laying a strong foundation for personal and professional growth. Candidates can apply to a maximum of two positions and will be considered for jobs in the order you apply. The application limit is applicable to ByteDance and its affiliates' jobs globally. Applications will be reviewed on a rolling basis. We encourage you to apply as early as possible. Please state your availability clearly in your resume (Start date, End date). Summer Start Dates: - May 11th, 2026 - May 18th, 2026 - May 26th, 2026 - June 8th, 2026 - June 22nd, 2026 Responsibilities - Mechanical prototypes to enable testing of: - Optical and sensing concepts - Cameras, sensors, and perception experiments - Ergonomics and human-factors studies - Prototype-only mechanical structures, such as: - Optical and sensor mounts - Adjustable frames and alignment fixtures - Bench-top and head-worn test rigs - Rapid design iterations driven by experimental results, not design-freeze milestones - Fabrication and modification of prototype parts using rapid prototyping methods, including: - 3D printing (FDM, SLA, and similar processes) - Simple CNC machining or manual shop tools - Laser cutting and sheet-based fabrication - Off-the-shelf mechanical components and fasteners

Candidate Requirements:

Minimum Qualifications - Currently pursuing an MS or PhD in Mechanical Engineering or a related field - Able to commit to working for 12 weeks during Summer 2026 - Solid understanding of mechanical fundamentals, including: - Statics, materials, tolerances, and basic GD&T - Experience with 3D CAD, such as: - SolidWorks, Creo, NX, or Fusion 360 - Comfortable working with physical hardware, tools, and prototype builds - Ability to learn quickly and operate effectively in an iterative, ambiguous environment Preferred Qualifications - Experience with consumer electronics or wearable devices - Familiarity with AR systems, optics, or camera modules - Hands-on experience with: - 3D printing workflows and post-processing - Fasteners, adhesives, and bonding methods - Exposure to DFM / DFA concepts (for prototype awareness) - Basic understanding of thermal considerations in compact hardware systems
