Senior Principal Hardware Electrical Engineer

Mercury Systems is offering a Senior Principal Hardware Electrical Engineer a fulfilling career where you will be able to see the direct impact of your designs in deployed systems with true end-to-end ownership, operating in a smaller, highly technical team. You’re not just implementing requirements; you’re shaping ruggedized solutions that must perform in the real world under extreme conditions. Engineers here directly influence architecture, design decisions and system-level tradeoffs across the systems. You will lead and mentor engineering teams developing mission-critical embedded computing, high-speed digital systems, advanced FPGA solutions, secure processing and rugged electronics supporting operations across air, land, sea, and space.

Step into a role where you can remain deeply hands‑on, take ownership of end‑to‑end technical work, and shape the next generation of defense and aerospace products. You’ll lead innovation and deliver high‑reliability, mission‑critical solutions from day one.

Job Responsibilities:

Provide strategic technical leadership and execution for complex digital hardware programs from concept through production

Architect advanced electrical circuit solutions involving secure processing, storage, networking, FPGAs, high-speed interfaces, and extreme environment electronics

Develop advanced high-speed digital design including 400G+ Ethernet, PCIe Gen5+, DDR5+, and modern interconnects

Contribute to engineering best practices, design guidelines, and process improvements that scale across the organization

Execute the development and verification of highly complex circuits, modules, and systems

Advise senior leadership on technical risks, cost, schedule, and strategic direction

Required Qualifications:

BS in Electrical Engineering or Computer Engineering

Typically requires 10+ years relevant electrical design including complex embedded digital hardware from concept through production

Experience with high-speed and high-performance interface s, memory technologies, and next generation interconnects

Experience with signal integrity

US Citizenship is required.

This position requires you to access information that is subject to U.S. export regulations. You may only access such information if you are 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 the required authorizations from the U.S. government
