Senior Signal and Power Integrity Engineer — SI/PI, Satellites (Starlink)
SpaceXJob Title
Senior Signal and Power Integrity Engineer — SI/PI, Satellites (Starlink)
Role Summary
Lead SI/PI design, analysis, verification, and production signoff for Starlink satellite payload hardware across the full product life cycle. Work at the intersection of electrical, mechanical, thermal, RF/antenna, packaging, and software engineering to define architectures, troubleshoot hardware, and establish SI/PI processes.
This role is cross-functional and requires defining best practices, simulation workflows, test methodologies, and lab needs for high-speed digital channels and complex power delivery networks.
Experience Level
Senior. Hiring guidance: typically 5+ years industry experience in circuit or hardware design with multi-disciplinary system-level SI/PI responsibility.
Responsibilities
Primary duties include technical ownership of SI and PI for satellite payload hardware from architecture through production.
- Specify, design, simulate, verify, qualify, and troubleshoot SI and PI for high-speed wireline and optoelectronic links, memory interfaces, and ASIC/FPGA power delivery networks.
- Define PCB material, stackup, and channel component specifications; optimize transitions from die bump to die bump across package and PCB.
- Collaborate with RF, antenna, ASIC, packaging, mechanical, thermal, software, supply chain, and production teams to architect robust channels and PDNs.
- Drive root-cause analysis and fixes for PCB manufacturing, PCBA testing, and satellite integration issues.
- Establish simulation workflows, lab test methodologies, signoff criteria, and required test equipment for SI/PI verification.
Requirements
Minimum technical qualifications and job constraints.
- 5+ years industry experience designing circuits, electronic products, or hardware (full product life-cycle preferred).
- 2+ years experience using 3D EM and high-speed channel simulation tools (e.g., CST, HFSS, ADS) and channel/PDN simulation workflows.
- 2+ years research or industry experience with high-speed digital design or power integrity.
- Experience with high-speed SERDES, high-bandwidth memory interfaces, or PDN architecture is strongly preferred.
- Strong scripting/programming skills (Python, C/C++ recommended) for automation and analysis.
- Experience with PCB materials, high-volume PCB manufacturing, connectors, and EMI/EMC debugging is desirable.
- Ability to work extended hours or weekends for mission-critical deadlines; occasional travel may be required.
- Must meet ITAR eligibility requirements: U.S. citizen, U.S. lawful permanent resident, refugee, asylee, or be eligible to obtain required U.S. Department of State authorizations.
Education Requirements
Minimum: Bachelor’s degree in Electrical Engineering, Computer Engineering, or Physics. Preferred: Master’s degree or PhD in Electrical or Computer Engineering with emphasis in electromagnetic theory, transmission line theory, wireline transceivers, or power integrity. Relevant advanced degrees and specialized coursework/certifications in high-speed digital design, electromagnetics, or power integrity are a plus.
