Materials Engineering Intern (Summer 2027) New Los Angeles, CA (On-site)

MATERIALS ENGINEERING INTERN (SUMMER 2027) Freeform builds AI-native manufacturing systems that unify software, hardware, and physics to produce industrial-scale parts at the speed of human ideation. By treating manufacturing as a single integrated system, we unlock a new era of innovation where complex hardware is designed, built, and scaled without limits. As a Materials Engineering Intern at Freeform, you will help establish and refine materials testing infrastructure and best practices for some of the world's most advanced metal 3D printing systems. You will work closely with experienced engineers to study material behavior within the printing process, building a foundational understanding of metals characterization and applying those insights to support materials testing and process improvement. You'll collaborate with process development, mechanical, and simulation engineers to analyze material property data and post-print characteristics, contributing to rapid iteration and continuous improvement of the printing technology. 3D printing experience is not required to be successful here, we look for smart, motivated, collaborative engineers who love solving hard problems and creating amazing technology! Responsibilities: Assist the Materials Engineering team in operating equipment to measure material properties such as tensile strength, surface roughness, and microstructure Support generation and tracking of quality metrics for printed customer parts such as dimensional accuracy, defect distribution, and surface roughness Organize, analyze, and help interpret materials data, and assist in presenting key findings Assist in developing and optimizing metallurgical sample preparation techniques such as cutting, grinding, polishing, acid etching, and optical microscopy Support the process development team in tying materials findings into upstream printing process improvements Help establish and refine procedures for measuring and quantifying material quality Basic Qualifications: Currently pursuing Bachelor's degree in materials science, materials engineering, metallurgy, mechanical engineering, or similar discipline Experience with experimental design and statistical data analysis Strong data analysis skills and ability to interpret important information from extremely large data sets Nice to Have: Undergraduate research experience in materials science, metallurgy, or mechanical engineering Exposure to metallurgical sample preparation such as cutting, grinding, polishing, acid etching, and optical microscopy Experience with metal additive manufacturing or laser powder bed fusion (LPBF) processes Experience operating materials characterization equipment (SEM, Instron, etc.) Experience with statistical data analysis software such as R, JMP, or Minitab Passion for improving the state of metal 3D printing Comfortable working in fast-paced, ambiguous environments and iterating quickly (comfortable building the plane as we fly it) Strong communicator who collaborates across disciplines and proactively seeks support when needed Willing to take ownership of tasks big and small, with a hands-on, problem-solving mindset Strong work ethic with a refuse-to-fail mindset Demonstrated indicators of excellence and/or achieving success against adversity (i.e. top academic performance, leadership in engineering clubs, first-generation college student, or other examples of resilience and achievement) Location: Based in Hawthorne, our vertically integrated facility brings technology development, R&D, and production together under one roof. We operate at the center of LA’s deep tech ecosystem, surrounded by some of the most ambitious hardware innovation happening anywhere in the country. Our fast-paced, cross-functional environment is built on close collaboration, and as such, this role requires full-time onsite presence (five days a week), with very limited exceptions. What We Offer: We have an inclusive and diverse culture that values collaboration, learning, and making deliberate data-driven decisions We offer a unique opportunity to be an early and integral member of a rapidly growing company that is scaling a world-changing technology Compensation and Benefits The compensation for this role: Engineering Intern/Undergraduate: $30/hour Engineering Intern/Masters: $32.50/hour Engineering Intern/PhD: $35/hour Relocation assistance provided Free daily catered lunch and dinner, and fully stocked kitchenette Casual dress, flexible work hours, and regular catered team building events Freeform is an Equal Opportunity Employer that values diversity; employment with Freeform is governed on the basis of merit, competence and qualifications and will not be influenced in any manner by race, color, religion, gender, national origin/ethnicity, veteran status, disability status, age, sexual orientation, gender identity, marital status, mental or physical disability or any other legally protected status. Export Compliance: Due to the nature of various Freeform customers, the person hired will have access to information and items controlled by the International Traffic in Arms Regulation (ITAR), and, therefore, must be a “U.S. person” as defined in the ITAR which include U.S. citizens, lawful permanent residents (i.e., Green Card holders), and certain protected individuals (i.e., refugees/asylees, American Samoans). Please consult with a knowledgeable advisor if you are unsure whether you are a “U.S. Person.” If \"Other\", please explain: Voluntary Self-Identification For government reporting purposes, we ask candidates to respond to the below self-identification survey.Completion of the form is entirely voluntary. Whatever your decision, it will not be considered in the hiringprocess or thereafter. Any information that you do provide will be recorded and maintained in aconfidential file. Voluntary Self-Identification of Disability Form CC-305 Page 1 of 1 OMB Control Number 1250-0005 Expires 07/31/2029 Why are you being asked to complete this form? We are a federal contractor or subcontractor. The law requires us to provide equal employment opportunity to qualified people with disabilities. We have a goal of having at least 7% of our workers as people with disabilities. The law says we must measure our progress towards this goal. To do this, we must ask applicants and employees if they have a disability or have ever had one. People can become disabled, so we need to ask this question at least every five years. Completing this form is voluntary, and we hope that you will choose to do so. Your answer is confidential. No one who makes hiring decisions will see it. Your decision to complete the form and your answer will not harm you in any way. If you want to learn more about the law or this form, visit the U.S. Department of Labor’s Office of Federal Contract Compliance Programs (OFCCP) website at . How do you know if you have a disability? A disability is a condition that substantially limits one or more of your “major life activities.” If you have or have ever had such a condition, you are a person with a disability. Disabilities include, but are not limited to: Alcohol or other substance use disorder (not currently using drugs illegally) Autoimmune disorder, for example, lupus, fibromyalgia, rheumatoid arthritis, HIV/AIDS Blind or low vision Cancer (past or present) Cardiovascular or heart disease Celiac disease Cerebral palsy Deaf or serious difficulty hearing Diabetes Disfigurement, for example, disfigurement caused by burns, wounds, accidents, or congenital disorders Epilepsy or other seizure disorder Gastrointestinal disorders, for example, Crohn's Disease, irritable bowel syndrome Intellectual or developmental disability Mental health conditions, for example, depression, bipolar disorder, anxiety disorder, schizophrenia, PTSD Missing limbs or partially missing limbs Mobility impairment, benefiting from the use of a wheelchair, scooter, walker, leg brace(s) and/or other supports Nervous system condition, for example, migraine headaches, Parkinson’s disease, multiple sclerosis (MS) Neurodivergence, for example, attention-deficit/hyperactivity disorder (ADHD), autism spectrum disorder, dyslexia, dyspraxia, other learning disabilities Partial or complete paralysis (any cause) Pulmonary or respiratory conditions, for example, tuberculosis, asthma, emphysema Short stature (dwarfism) Traumatic brain injury Disability Status Select... PUBLIC BURDEN STATEMENT: According to the Paperwork Reduction Act of 1995 no persons are required to respond to a collection of information unless such collection displays a valid OMB control number.
