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.a
You are a self-starter with a strong command of microstructure-processing-properties relationships in aerospace alloys and thrive at the intersection of hands-on lab work and cross-functional collaboration.a
Responsibilities
Powder & Feedstock Materialsa
- Own incoming qualification and lot acceptance of metallic feedstocks (PSD, morphology, chemistry, flowability, density)a
- Develop and maintain feedstock control procedures aligned with AM process requirements
- Characterize powder degradation and establish reuse limits, blending protocols, and out-of-life criteriaa
- Manage powder suppliers: acceptance specs, source approvals, and non-conformancesa
Surface Finishing & Post-Processinga
- Define and qualify AM surface finishing: tumbling, vibratory finishing, electropolishing, chemical etching, shot peening, and precision machininga
- Characterize surface roughness (Ra/Rz/Sa), residual stress, and sub-surface microstructure before and after finishinga
- Qualify coatings and surface treatments (anodize, hard coat, conversion coating, thermal spray, PVD/CVD) for corrosion, wear, and fatigue requirementsa
- Establish acceptance criteria and inspection methods for finished AM surfacesa
- Identify and qualify heat treatment processes for AM parts (stress relief, HIP, solution treat and age)a
Specifications, Suppliers & Compliancea
- Investigate coupon- and component-level failures; perform fracture analysis and drive corrective actionsa
- Author material and process specifications covering feedstock, build parameters, post-processing, and acceptance criteriaa
- Support materials allowables and design-allowable data packages for FAA certificationa
- Partner with stress, design, and quality on material inputs, qualification packages, and MRB dispositionsa
Required
- B.S. degreeaand 5+ years of industry experience in metallic materials characterization, processing, or manufacturing engineeringa
- M.S degree and 3+ years of relevant industry experience as stated above
- Working knowledge of metallic powder characteristics, handling, and qualificationa
- Familiarity with one or more metal AM processesa
- Experience with common materials characterization techniques (e.g., microscopy, hardness, mechanical testing)a
- Strong written and verbal communication; able to author specs and present to cross-functional stakeholdersa
- Able to work independently in a fast-paced environment and meet program deadlines (onsite in Marina, CA)
Desired
- Ph.D. in Materials Science, Metallurgical Engineering, or a related field of study
- 5+ years in a controlled/certified manufacturing environment (AS9100, NADCAP, or equivalent)a
- Hands-on with the full powder lifecycle: atomization, sieving, morphology, reuse qualification, and disposala
- Practical knowledge of AM surface finishing and its effect on fatigue life and dimensional compliancea
- Experience with AM-specific defects: porosity, lack of fusion, keyhole voids, residual stress, and anisotropya
- Familiarity with X-ray CT for AM defect and dimensional inspectiona
- Prior experience authoring M&P specifications in regulated aerospace environments
- Exposure to fatigue/fracture testing, allowables generation, or FAA certification data packagesa
