Job Description

Senior Principal Electrical Engineer

Position Overview IS4S is seeking an experienced Senior Principal Electrical Engineer with over 15 years of experience to serve as a technical lead in the development of advanced defense technologies. This individual will act as the primary architect for complex electrical systems, overseeing the full-spectrum design, integration, and qualification of high-reliability PWA/CCAs and ruggedized interconnects for critical Department of Defense (DoD) programs.

The ideal candidate is a technical authority capable of bridging the gap between high-level system requirements and detailed hardware implementation while mentoring junior engineering staff.

Key Responsibilities

• System Architecture & Strategy: Architect high-complexity electrical systems and sub-systems, ensuring hardware designs align with overarching mission requirements and long-term technology roadmaps.
• Design Oversight & Peer Review: Lead technical design reviews (PDR, CDR) and provide expert-level oversight of schematic capture, PCB layout, and component selection for high-speed digital and precision analog systems.
• Advanced Interconnect Engineering: Drive the strategy for complex, ruggedized cable and harness architectures, ensuring survivability in extreme military environments and adherence to strict size, weight, and power (SWaP) constraints.
• Test & Qualification Strategy: Define and lead comprehensive verification and validation (V&V) plans. This includes overseeing EMI/EMC testing, environmental qualification, and hardware-in-the-loop integration.
• Cross-Functional Leadership: Serve as the primary technical liaison between mechanical, software, and systems engineering teams to resolve complex multi-disciplinary integration challenges.
• Mentorship & Standards: Establish and maintain internal engineering best practices, design standards, and documentation protocols. Act as a dedicated mentor to junior and mid-level electrical engineers.

Technical Qualifications

• Education: Bachelor of Science in Electrical Engineering (BSEE) from an ABET-accredited institution; Master’s (MSEE) or PhD preferred.
• Experience: 15+ years of progressive experience in electrical hardware design within the aerospace, defense, or national security sectors.
• SME-Level Circuit Design: Mastery of low-noise analog design, power electronics, and high-speed digital interfaces (e.g., PCIe, DDR4, FPGA integration).
• Regulatory & MIL-STD Expertise: Deep, practical knowledge of MIL-STD-461 (EMI/EMC), MIL-STD-810 (Environmental), and IPC-2221/2222 standards.
• Tool Mastery: Expert-level proficiency in EDA suites (e.g., Altium Designer, Cadence Allegro) with a focus on signal integrity (SI) and power integrity (PI) analysis.
• Hardware Lifecycle Management: Demonstrated experience taking multiple high-reliability products from initial concept through production and field deployment.
• Security: Ability to obtain and maintain a DoD Secret Security Clearance.

Benefits Summary

• Competitive salary with comprehensive health and wellness benefits
• Dynamic and collaborative work environment
• Employee ownership
• Medical, dental, and vision care plans
• Paid time-off and parental leave programs
• Group term life insurance
• 401(k) retirement plan
