About the role

Original posting from Quantum Space via Greenhouse

Quantum Space is redefining mobility and maneuverability in space. Our high-mobility spacecraft platforms support national security, civil, and commercial missions with unmatched flexibility and propulsion capability. We build fast and iterate quickly.

Who We're Looking For

We are seeking an experienced Senior Materials and Process Engineer III to lead the development, qualification, and implementation of metallic materials and manufacturing processes for next-generation spacecraft structures, propulsion systems, and flight hardware. This role is ideal for an engineer with deep expertise in aerospace metallic materials, joining technologies, process qualification, and manufacturing development who thrives in a fast-paced environment supporting both hardware development and flight production.

You will work closely with propulsion, mechanical, manufacturing, quality, and test engineering teams to select, qualify, and optimize metallic materials and manufacturing processes that enable reliable, high-performance spacecraft systems. This highly collaborative role combines technical leadership, hands-on engineering support, root cause analysis, and process development across the entire product lifecycle - from early development through flight production.

Where You’ll Make an Impact

Lead the selection, development, qualification, and implementation of metallic materials and manufacturing processes for spacecraft structures, propulsion systems, and flight hardware

Develop and qualify friction stir welding (FSW), welding, brazing, heat treatment, machining, forming, additive manufacturing, and other metallic fabrication processes to support spacecraft production

Provide technical leadership for materials selection, compatibility assessments, and manufacturing process development across multidisciplinary engineering teams

Provide technical expertise in the optimization and qualification of friction stir welding, electron beam welding, laser welding, TIG welding, and other advanced joining processes for flight-critical hardware

Develop process specifications, material specifications, qualification plans, and manufacturing standards to support production and flight certification

Investigate material failures, manufacturing anomalies, and nonconformances using root cause analysis and corrective action methodologies

Support design reviews by providing guidance on material selection, manufacturability, structural integrity, and production readiness

Collaborate with manufacturing, quality, and supplier teams to improve production efficiency, process capability, repeatability, and hardware quality

Support supplier qualification, material validation, and special process oversight to ensure compliance with aerospace standards

Define and oversee mechanical testing, metallurgical evaluations, nondestructive evaluation (NDE), and material characterization activities

Drive continuous improvement initiatives that enhance manufacturing quality, reduce risk, and improve cost and schedule performance

Mentor junior engineers while serving as the technical authority for metallic materials and manufacturing processes

Support spacecraft development, qualification, and production efforts in a dynamic, fast-paced aerospace environment
