About Zipline

Zipline’s mission is to provide every human on Earth with instant access to vital medical supplies. We believe that where you live should never dictate whether you live. We are at the forefront of a logistics revolution, using autonomous aircraft to deliver just-in-time, life-saving medical supplies at national scale in several countries and expanding around the world. Are you interested in building a system that 500 million people will depend on with their lives?

About the Role

As a Supplier Industrialization Engineer (SIE) focused on composite materials and structures, you will play a critical role in scaling Zipline’s manufacturing supply chain from early prototypes to full-rate production. You’ll serve as a key technical partner to the hardware engineering team, embedding Design for Manufacturability (DFM) and Design for Assembly (DFA) principles into composite part and assembly designs. You will also lead supplier development, process optimization, and quality assurance for advanced composite manufacturing, ensuring the production of lightweight, structurally reliable, and cost-efficient components at scale.

Composites at Zipline are broad in scope, ranging from traditional carbon fiber prepreg structures to advanced thermoset composite systems using epoxy adhesives, thermoplastics, and polymer-resin matrices. Understanding how fiber reinforcements interact with curing agents—whether through resin infusion, heat-cured epoxies, or thermoplastic matrix systems—is central to this role. This is a high-impact opportunity to architect how our most critical structural components are built, tested, and scaled.

What You’ll Do Supplier Development & Process Scaling Qualify and manage suppliers specializing in carbon fiber, glass fiber, and other fiber-reinforced composite systems, including thermoset and thermoplastic-based processes.

Assess and develop manufacturing processes involving prepreg layup, vacuum bagging, autoclave curing, resin infusion, out-of-autoclave methods, and bonded assemblies.

Support material selection and supplier collaboration across a wide range of fiber types, curing chemistries, and resin systems—from high-strength carbon fiber to structural glass composites.

Quality & Process Control Drive implementation of pFMEAs, SPC, and control plans tailored to composite layup, curing variability, and bond-line performance.

Lead failure analysis efforts related to delamination, voiding, resin-rich zones, or adhesive bond failures.

Validate key process parameters like fiber orientation, resin content, cure cycle consistency, and post-cure dimensional stability.

Utilize tools such as JMP, Minitab, or R for data-driven decision-making and continuous improvement of supplier performance.

Manufacturing Readiness & Optimization Collaborate with Design Engineers to ensure that composite parts are optimized for manufacturability, cure consistency, and mechanical performance.

Develop DFM guidelines specific to composite part geometry, ply schedules, and integrated bonding features.

Support the development and qualification of thermoset adhesive systems used to join composite-to-composite and composite-to-metal interfaces.

Lead efforts to streamline tooling design, trimming/finishing operations, and bonding workflows to support production ramp-up.

Implement in-line and end-of-line inspection systems including NDT (ultrasound, thermography) for early defect detection. What You’ll Bring

✅ 7+ years of experience in Supplier Industrialization, Manufacturing Engineering, or Supplier Quality, with deep focus in composite materials and structural systems
