Signal Integrity Engineer Jobs in Alabama (NOW HIRING)

Aurex is a mission-focused aerospace and defense company building the next frontier of deterrence. From hypersonics and missile defense to hardened networks and orbital systems, we design, test, and deliver the platforms that turn unproven ideas into battlefield-ready capability.

Born in Huntsville and built for speed, Aurex brings together aerospace veterans, combat-tested operators, and forward-leaning technologists to solve problems that matter—fast. We move from whiteboard to warfighter with precision, clarity, and zero tolerance for fluff.

As an Electrical Engineer specializing in Circuit Card Assemblies (CCAs) and Printed Wiring Boards (PWBs), you’ll be at the heart of our product development process. Your designs will become the backbone of systems that must perform without fail—whether in the depths of space, the heat of a jet engine, or the precision of a medical device. You won’t just be designing boards—you’ll be shaping the performance, reliability, and future of our technology.

• Lead the design and development of CCAs and PWBs from concept through production release.
• Create detailed schematics, layouts, and documentation using industry-standard CAD tools (e.g., Altium Designer, OrCAD, Mentor Graphics).
• Collaborate with mechanical, manufacturing, and test engineers to ensure designs meet performance, manufacturability, and cost targets.
• Perform component selection, signal integrity analysis, and power distribution design for high-reliability applications.
• Oversee prototype builds, conduct design reviews, and support troubleshooting during integration and testing.
• Ensure compliance with IPC standards, EMI/EMC requirements, and applicable military or aerospace specifications.

• Bachelor’s degree in Electrical Engineering or related field (Master’s preferred).
• 3+ years of experience designing CCAs and PWBs for high-reliability or mission-critical systems.
• Proficiency with PCB design tools such as Altium Designer, OrCAD, or Mentor Xpedition.
• Strong understanding of signal integrity, grounding, and power distribution best practices.
• Experience with design for manufacturability (DFM) and design for testability (DFT).
• Familiarity with IPC-2221/2222 standards and MIL-STD design requirements.
• A collaborative mindset and the ability to communicate complex technical concepts clearly

• Strong background in circuit design and power electronics, including switch-mode power supply design, battery systems, and Li-Po battery management
• Proficiency in circuit simulation tools (e.g., SPICE, LTSpice) and hands-on lab testing/troubleshooting with oscilloscopes and other diagnostic equipment
• Experience implementing microcontrollers and communication protocols such as serial, RS232/485, I2C, SPI, and Ethernet
• Knowledge of manufacturing processes for electronics (e.g., PCB fabrication, soldering, assembly)
• Experience with rapid prototyping techniques for circuits and systems

The salary range for this role is $107,000 - $135,000.00 per year. We offer a comprehensive total rewards approach to compensation, providing incentives and benefits that extend far beyond the base salary. Compensation is determined by the candidate’s work experience, education, training, and relevant skills. We offer a competitive benefits package designed to support our employees' health, well-being, and professional growth.
