TPI Composites – Why Work For Us?

We were founded in 1968 and have been providing composite wind blades since 2001. Our knowledge and experience of composite materials and manufacturing originates with our predecessor company, Tillotson Pearson Inc., a leading manufacturer of high-performance sail and powerboats along with a wide range of composite structures used in other industrial applications. We are headquartered in Scottsdale, Arizona, and we have expanded our global footprint to include domestic facilities in Newton, Iowa; Fall River, Massachusetts; Warren, Rhode Island; and Santa Teresa, New Mexico and international facilities in Dafeng, China; Taicang Port, China; Taicang City, China; Yangzhou, Jiangsu, China; Kolding, Denmark; Chennai, India; Juarez, Mexico; Matamoros, Mexico; and Izmir, Turkey.

We are the largest U.S.-based independent manufacturer of composite wind blades. We enable many of the industry’s leading wind turbine OEMs, who have historically relied on in-house production, to outsource the manufacturing of some of their wind blades through our global footprint of advanced manufacturing facilities strategically located to serve large and growing wind markets in a cost-effective manner. Given the importance of wind energy capture, turbine reliability and cost to power producers, the size, quality and performance of wind blades have become highly strategic to our OEM customers. As a result, we have become a key supplier to our OEM customers in the manufacture of wind blades and related precision molding and assembly systems. We have entered into long-term supply agreements pursuant to which we dedicate capacity at our facilities to our customers in exchange for their commitment to purchase minimum annual volumes of wind blade sets, which consist of three wind blades. This collaborative dedicated supplier model provides us with contracted volumes that generate significant revenue visibility, drive capital efficiency and allow us to produce wind blades at a lower total delivered cost, while ensuring critical dedicated capacity for our customers. We also leverage our advanced composite technology and history of innovation to supply high strength, lightweight and durable composite products to the transportation market.

Opportunity. It’s in the wind.

How does it feel to be part of the largest U.S.-based independent manufacturer of composite wind blades for the wind energy market?

    Process Engineer Interview

    Anonymous Interview Candidate in Newton, IA
    No Offer
    Negative Experience
    Easy Interview


    I applied online. I interviewed at TPI Composites (Newton, IA) in April 2017.


    Applied online for a Process Engineer opening. People were very friendly and the interview itself was easy. Basic behavioral questions. They found a better fit for a company of their size with a different candidate, which is fine and I understood. What made the experience negative was I traveled nearly 600 miles (driving) for the interview, and they won't return any emails, calls, or voicemails about my transportation reimbursement. I have no issue with them finding a better candidate than me, but not staying true to your word for reimbursing my mileage and meals is very unprofessional. Make sure you get it in writing.
