Internship Unity 3D Developer Jobs in Texas (NOW HIRING)

The Junior Design Engineer will support the design, development, validation, and release of battery interconnect products from concept through production. This role is highly CAD-intensive and ideal for an early-career engineer with strong 3D modeling skills and an interest in EV battery systems, flexible circuits, and high-voltage interconnect technologies.

The ideal candidate enjoys hands-on engineering work, thrives in a fast-paced environment, and wants exposure to product development from prototype through manufacturing release.

Essential Duties and Responsibilities

• Create and maintain detailed 3D CAD models and 2D manufacturing drawings for current collector assemblies, battery interconnect systems, voltage sense harnesses, and related components.

• Support design and release activities for battery products from concept through production.

• Work closely with senior engineers to develop and refine design solutions for EV battery applications.

• Assist with component selection and electrical interface methods, including welded, crimped, soldered, ZIF, and other termination solutions.

• Support prototype builds, hands-on assembly activities, and engineering development testing.

• Participate in design reviews and DFM/DFA discussions with engineering and manufacturing teams.

• Support engineering change activities, drawing revisions, BOM updates, and product release documentation.

• Assist in DVP&R development and validation activities.

• Contribute to DFMEA, APQP documentation, and release-related engineering deliverables.

• Partner with manufacturing, process engineering, and quality teams during product builds and launch activities.

• Support root cause investigations and design updates during prototype and early production phases.

Minimum Qualifications (Education, Knowledge, Skills, and Abilities)

• Bachelor's degree in Mechanical Engineering, Electrical Engineering, Materials Science, Physics, or related technical discipline.

• 0–3 years of professional experience or relevant internship/co-op experience.

• Strong proficiency with 3D CAD tools (SolidWorks strongly preferred; NX experience also considered).

• Experience creating detailed manufacturing drawings and applying GD&T fundamentals.

• Strong interest in EV battery systems, battery interconnects, flexible circuits, or power distribution systems.

• Exposure through school projects, internships, Formula SAE, robotics, or industry experience is highly valued.

• Familiarity with DFM principles and product development processes.

• Hands-on experience with prototyping, mechanical assembly, or lab work preferred.

• Familiarity with DFMEA, DVP&R, APQP, or structured validation processes is a plus.

• Exposure to FEA, simulation, or thermal analysis is preferred but not required.

• Ability to work cross-functionally in a fast-paced engineering environment.

• Formula SAE, Baja, EV clubs, battery projects, or relevant internship experience

• Exposure to battery pack systems or high-voltage applications

• Experience with prototype builds or manufacturing environments

• Experience with flexible circuits, harnesses, connectors, or electrical assemblies

IMPORTANT: The Junior Engineer will be working on ITAR programs and must be considered a U.S. person in accordance with ITAR standards.
