Sr. Electrical Design Engineer, Raptor 3D Printers

The Raptor Printer team designs, builds, and integrates in-house Laser Powder Bed Fusion (LPBF) printers that enable high-volume production of Raptor engines. We own the full product lifecycle of these critical manufacturing systems—from concept through production deployment—and continuously push the boundaries of additive manufacturing reliability, performance, and scale.

As a Senior Electrical Design Engineer on this team, you will be the extreme owner of electrical systems for next-generation LPBF printers. You will drive requirements definition, circuit design, development, qualification, and seamless integration into production. This role offers end-to-end ownership of complex electromechanical systems in a high-stakes, fast-paced environment where your designs directly impact rocket engine production rates and reliability.

• Design new electrical hardware, PCBAs, and implement targeted modifications to improve reliability, manufacturability, and expand printer capabilities
• Create and release documentation for fabrication of PCBs
• Provide extreme ownership of electronic hardware on additive machines from development through implementation
• Drive changes to electrical schematics and mechanical drawings that improve reliability, manufacturability, and cost
• Perform root cause investigations to characterize off-nominal unit behavior and mitigate risk
• Derive engineering justification to resolve production issues throughout assembly, test, and activation
• Design test setups and execute hardware validation through benchtop and environmental testing
• Work closely with engineers from adjacent disciplines (mechanical, software, automation and controls, additive, etc.) to deliver tightly integrated, high-performance hardware
• Drive system trades, requirements capture, component selection, analysis, schematic capture, PCB layout, prototyping, hardware bring-up, debugging, documentation, manufacturing, test, and activation of complex electrical designs
• Challenge assumptions, question requirements, learn from your mistakes, and approach problems with an open mind

Basic qualifications

• Bachelor’s degree in electrical engineering or computer engineering
• 5+ years of industry experience designing circuits, electronic products, or hardware

Additional requirements

• Extended hours and weekend work may be required to support critical project and mission milestones

Level 3: $140,000.00 - $230,000.00

Your actual level and base salary will be determined on a case-by-case basis and may vary based on the following considerations: job-related knowledge and skills, education, and experience.

Base salary is just one part of your total rewards package at SpaceX. You may also be eligible for long-term incentives, in the form of company stock or long-term cash awards, as well as potential discretionary bonuses and the ability to purchase additional stock at a discount through an Employee Stock Purchase Plan. You will also receive access to comprehensive medical, vision, and dental coverage, access to a 401(k) retirement plan, short and long-term disability insurance, life insurance, paid parental leave, and various other discounts and perks.

You may also accrue 3 weeks of paid vacation and will be eligible for 10 or more paid holidays per year. Employees accrue paid sick leave pursuant to Company policy which satisfies or exceeds the accrual, carryover, and use requirements of the law.

SpaceX was founded under the belief that a future where humanity is out exploring the stars is fundamentally more exciting than one where we are not. Today SpaceX is actively developing the technologies to make this possible, with the ultimate goal of enabling human life on Mars.
