About the Role

SOE is seeking a High Speed Digital Electrical Engineer to contribute to client programs requiring cutting-edge hardware performance. This hands-on design role involves owning high-speed digital PCB design, signal integrity, and FPGA development for diverse applications including space avionics, optical communication systems, power electronics, and embedded computing. You will collaborate with experienced engineers, gain direct client exposure, and work on unique programs.

Responsibilities

Support high speed electrical architecture from concept generation through investigation, including key trades, requirement definition, investigations, and component selection.
Own signal integrity from component selection and schematic capture through layout and post-route simulation, including impedance control, differential pair routing, crosstalk analysis, and eye diagram verification.
Collaborate with power electronics engineers to inform and design power delivery networks for high-performance ASICs, FPGAs, and multi-channel memory, managing power budgets from system architecture through regulator selection and decoupling strategy.
Develop and execute high-speed board bring-up, including BERT testing, TDR characterization, eye mask compliance, and EMC pre-compliance.
Design in Altium and produce layout-ready packages with full design rule documentation for contract manufacturing.
Incorporate environmental requirements across programs, such as radiation tolerance, thermal cycling, vibration, shock, and vacuum outgassing.
Select and qualify components for space-grade or radiation-tolerant operation, manage parts lists, and evaluate COTS mitigation strategies.
Select and implement best design practices to minimize the risk of EMI/EMC test failures, with familiarity in industry standards like STD-461, DO-160, and MIL-STD-461.
Author and maintain design specifications, interface control documents, and test procedures.
Work directly with clients to translate system requirements into board-level hardware specifications.
Contribute to technical reviews (PDR, CDR) as both a presenter and reviewer.
Support junior engineers through design reviews and hands-on mentorship.
Contribute to SOE's internal body of knowledge, including reusable design patterns, documentation standards, and lessons learned.

Requirements

Bachelor's Degree in Electrical Engineering, Computer Science, Physics, Math, or related field.
5+ years of applied experience with a demonstrated passion for engineering and technology development.
Experience with high-speed test equipment and debug tools: BERT, VNA, TDR, high-bandwidth oscilloscopes (20 GHz+), and logic analyzers.
Excellent written and verbal technical communication skills; ability to explain technical concepts and their implications to non-technical audiences.
A systems-thinking approach, with the ability to connect engineering execution to business strategy.
A proven track record of leading technical initiatives, mentoring engineers, and driving process improvements.
A bias for action, thriving in a fast-paced consulting environment where priorities can shift quickly.
Willingness to be deeply involved in both high-level strategy and hands-on technical execution.
Applicant must be willing to work 40 hours a week on-site in El Segundo, California, USA.
Applicant must be eligible to work on ITAR projects.
Must be a U.S. citizen, lawful permanent resident of the U.S., protected individual as defined by 8 U.S.C. 1324b(a)(3), or eligible to obtain necessary U.S. Department of State authorizations.
Company is unable to provide sponsorship at this time.
