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
Joby Aviation is seeking an experienced materials engineer to join our Additive Manufacturing team. You will own the full material lifecycle for AM metallic components—feedstock qualification through post-processing and failure analysis as a principal contributor to Joby's materials qualification program supporting eVTOL development, certification, and production.
You are a self-starter with a strong c ommand of microstructure-processing-properties relationships in aerospace alloys and thrive at the intersection of hands-on lab work and cross-functional collaboration.
Responsibilities
Powder & Feedstock Materials
- Own incoming qualification and lot acceptance of metallic feedstocks (PSD, morphology, chemistry, flowability, density)
- Develop and maintain feedstock control procedures aligned with AM process requirements
- Characterize powder degradation and establish re use limits, blending protocols, and out-of-life criteria
- Manage powder suppliers: acceptance specs, source approvals, and non-conformances
Surface Finishing & Post-Processing
- Define and qualify AM surface finishing: tumbling, vibratory finishing, electropolishing, chemical etching, shot peening, and precision machining
- Characterize surface roughness (Ra/Rz/Sa), residual stress, and sub-surface microstructur e before and after finishing
- Qualify coatings and surface treatments (anodize, hard coat, conversion coating, thermal spray, PVD/CVD) for corrosion, wear, and fatigue requirem ents
- Establish acceptance criteria and inspection methods for finished AM surface s
- Identify and qualify heat treatment processes for AM parts (stress relief, HIP, solution treat and age)
Specifications, Suppliers & Compliance
- Investigate coupon and component-level failures; perform fracture analysis and drive corrective actions
- Author material and process specifications covering feedstock, build parameters, post-processing, and acceptance criteria
- Support materials allowables and design-allowable data packages for FAA certification
- Partner with stress, design, and quality on material inputs, qualification packages, and MRB dispositions
Required
- B.S. degree and 5+ years of industry experience in metallic materials characterization, processing, or manufacturing engineering
- M.S degree and 3+ years of relevant industry experience as stated above
- Working knowledge of metallic powder characteristics, handling, and qualification
- Familiarity with one or more metal AM processes
- Experience with <span data-ccp-parastyle="List Bullet" style="margin: 0px; p
