Hardware Engineer III

Job Summary:

 
Mercury Systems is offering an experienced Hardware Engineer with a strong focus on rugged server integration. In this role, you will integrate and validate server components including risers, power supplies, cables, add-in cards, and highspeed interfaces, ensuring full system level electrical integrity. You will also design targeted supporting PCBs (such as riser cards, power distribution boards, or fan controllers) needed to optimize system performance and configurability. This position is ideal for an engineer who enjoys hands-on system bring up, debugging, and cross functional collaboration. 

Key Responsibilities:

• Lead electrical integration of rugged server systems, incorporating commercial and custom boards. 
• Own system level power architecture, including review, qualification, and integration of commercial power supplies. 
• Integrate risers, cabling, add-in cards, and highspeed interfaces (PCIe Gen5, USB 3.x, SATA, Ethernet). 
• Perform targeted PCB design including riser cards, power distribution boards, and fan/control modules. 
• Address signal integrity issues and recommend cables, layouts, or red river-based solutions when needed. 
• Support thermal management by developing or integrating fan control solutions. 
• Collaborate with mechanical, test, software, and systems teams to ensure full system compliance. 
• Lead debug and root cause analysis across power, thermal, and highspeed digital domains. 
• Develop system electrical specifications, integration plans, and test procedures. 

Required Qualifications:

• BS in Electrical Engineering or related field
• Typically requires 4 years of hardware development experience from concept through production.
• Hands-on experience with power supplies and high current system design. 
• Experience with schematic design using Cadence DEHDL/Concept or similar tools. 
• Understanding of signal integrity principles and best practices. 
• Strong cross-disciplinary communication skills and ability to lead technical efforts. 
• 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.

Preferred Qualifications:

• Experience adapting commercial power supplies to military or ruggedized applications.
• Strong experience with PC/server architectures and system level hardware integration. 
• Experience with digital interfaces (I2C, SPI, clocking and DC/DC power)
• Familiarity with MIL-STD704F, 1275, 1399, or MIL-STD461G.
• Experience with riser card, signal conditioning, or red river designs. 
• Knowledge of thermal management and fan control system design. 
• Experience with Intel CPU architecture and BIOS level integration. 
• Handson experience with microcontrollers for sequencing or control tasks. 
• Experience with Cadence Allegro for layout or SI simulation.
• The ability to obtain one. US Citizenship is required.
