Senior Substrate Layout Engineer

Mercury Systems is seeking the best and brightest engineering talent to help us deliver cutting‑edge technology for mission‑critical aerospace and defense applications, advancing innovation where it matters most.

In this role, our team is looking for a Senior Substrate Layout Engineer who will lead complex HDI PCB and substrate layout efforts for advanced microelectronic solutions used in aerospace, defense, and space systems.

You will contribute directly to the design, layout, and optimization of rugged, high‑density microelectronics that operate in the harshest environments with exceptional reliability.

This role serves as a technical authority within Mercury’s Microsystems business, driving layout excellence, influencing engineering standards, and shaping the technical direction of multiple high‑impact programs.

Working within Mercury’s Integrator Mindset, you will collaborate across sites and disciplines to deliver breakthrough microelectronics that strengthen national security and support onshore trusted manufacturing.

• Provide technical leadership focused on high‑speed interfaces and high‑density substrate layout techniques, guiding engineering teams to deliver high‑quality microelectronic solutions
• Drive the design, layout, and analysis of complex electrical and mechanical systems, including high‑density interposers, substrates, and PCB layouts supporting digital, analog, power, and RF signals across multiple die (primarily flip‑chip)
• Manage high‑speed, multi‑layer packaging activities involving HDI structures, blind and buried vias, BGAs, RF routing, and design‑for‑test (DFT) considerations
• Coordinate development processes to ensure alignment with supplier Design for Manufacturing (DFM) rules and capabilities
• Create fabrication drawings that accurately represent design intent and collaborate with fabrication suppliers to ensure successful technical transfer
• Review artwork, drawings, and design artifacts throughout the layout cycle and during final design reviews for fabrication and assembly
• Support multidisciplinary investigations, feasibility studies, and design trades in collaboration with cross‑functional engineering teams
