Materials and Process Engineer

Company Overview

Imagine a piloted air taxi that takes off vertically, then quietly carries you and your fellow passengers over the congested city streets below, enabling you to spend more time with the people and places that matter most. At Joby, we've been working to make that dream a reality since 2009 and we're now in the final stages of certifying our aircraft with the FAA. With plans to launch our aircraft in the US and Dubai, we're now scaling manufacturing and preparing for the launch of our commercial service.

Overview

Working as a Materials & Process Engineer at our Dayton, Ohio facility (JMO), you will support propeller blade process development activities leading to the certification and production of eVTOL aircraft. The role requires hands-on composite fabrication experience and a strong desire to work directly on the shop floor. The ideal candidate is a highly skilled engineer who thrives at the intersection of fabrication and process development, bridging the gap between engineering and manufacturing, and possesses the ability to work with minimal supervision within a small, focused team.

Responsibilities

Develop and optimize composite manufacturing processes for propeller blade fabrication, including dry fiber layup, resin transfer molding (RTM), vacuum bagging, curing, demolding, and post-cure operations

Support RTM process development using injection equipment, including resin system evaluation, injection parameter development, and cure cycle optimization

Perform hands-on composite fabrication in the blade development cell, working alongside production technicians

Execute laser-projected layup operations using lamination tables

Fabricate batch acceptance test panels in support of material qualification and process validation activities

Develop and maintain SOPs, Manufacturing Work Instructions (MWIs), and process specifications for blade manufacturing operations

Interpret and work with engineering drawings and process specifications for composite and bonded structures

Prepare and maintain molds, tooling, and fixtures associated with blade fabrication and development operations

Plan, execute, and report M&P testing for material qualification and process validation, including Incoming Resin Testing (IRT), DSC (Tg, degree of cure), FTIR and mechanical coupon testing

Specify, install, and validate Composite Test Lab equipment. Write test methods and SOPs for the test equipment

Record and analyze process data; document and communicate non-conformances and support root cause and corrective action (RCCA) activities

Maintain a clean, safe, and organized workspace, following all Joby safety procedures and OSHA regulations

Required

B.S. in Aerospace, Materials Science, Mechanical Engineering, or related engineering discipline

Demonstrated hands-on composite fabrication experience

Familiarity with composite manufacturing processes such as dry fiber layup, prepreg layup, vacuum bagging, resin infusion, or RTM

Ability to read and work from engineering drawings, work instructions, and process specifications

Strong attention to detail and critical thinking skills with a commitment to workmanship quality

Problem-solving mindset with a willingness to work on the shop floor and collaborate effectively with technicians and engineers

Proficiency in MS Office Suite and general computer skills

Desired

Advanced degree in Aerospace or Materials Engineering

Proficiency in 3DEXPERIENCE CATIA (3DX) or SolidWorks
