Job Description

Belcan is seeking a Principal PCB & Substrate Layout Engineer to provide technical leadership in high-speed interfaces and dense substrate layout for defense and aerospace microelectronics. This onsite Phoenix contract role calls for a Bachelor’s degree in engineering and at least ten years of hands-on PCB and HDI layout experience, with a focus on multi-die packaging and flip-chip implementations. The right candidate will guide complex designs from concept through fabrication, delivering robust PCBs and substrates that meet stringent military and aerospace standards.

Responsibilities

Lead the design, layout, and analysis of intricate electrical and mechanical systems, including high-density interposers, substrates, and multi-layer PCBs, handling power, digital, analog, and RF signals across multiple dies with a primary emphasis on flip-chip configurations.
Perform hands-on work on high-speed, multi-layer packaging and HDI interconnects, including blind and buried vias, BGAs, RF sections, design for test, impedance calculations, crosstalk, differential pairs, stack-ups, vias, EMC, and material studies/selection.
Ensure designs follow supplier design-for-manufacturing rules and align processes with supplier capabilities.
Prepare fabrication drawings that reflect design intent and support seamless transfer to fabrication suppliers.
Support package material characterization with frequency-dependent models, including skin effects, surface finish, roughness, dielectric loss, and dielectric constant.
Collaborate with peers to review artwork and drawings at various stages and participate in final design reviews for fabrication and assembly.
Support multidisciplinary investigations and feasibility studies across engineering disciplines.
Provide technical guidance interfacing with customers, subcontractors, assemblers, fabricators, vendors, operations, quality, supply chain, and supporting organizations.
Tackle complex issues that require in-depth analysis of variable factors and apply systems thinking to evaluate the impact on the overall system.
Contribute across disciplines to help the team achieve goals and deliverables.

Requirements

Bachelor’s Degree in Engineering or equivalent education and experience.
10+ years of PCB and/or High-Density Package Layout design experience using industry-standard tools such as Cadence APD+.
Proficiency with APD+ physical and electrical constraint editor.
Experience with HDI stack-ups, including blind and buried microvias, RF dielectric materials, and trace widths/spacings from approximately 15 μm down to 2 μm or smaller.
Experience with 2.5D devices, interposer or substrate design, flip-chip, surface mount, die stacking, package stacking, and substrate stacking techniques.
Experience using a Cadence schematic/netlist-driven CAD layout process (APD+/Allegro) and supporting tools.
High-end FPGA package or board design experience.
Ability to collaborate with the Mechanical team to develop full 3D models for fit checks and thermal analysis.
Understanding of layout techniques for digital, analog, and RF designs.
Knowledge of electronic packaging techniques.
Experience using a CAM package for manufacturing data validation; familiarity with CAM350 and Blueprint is preferred.
Working knowledge of JEDEC/IPC design, fabrication, and assembly specifications.
Experience creating assembly documentation and fabrication deliverables per company and industry standards.
Must be a US Person.
Ability to work effectively both independently and as part of a team.
Commitment to teamwork, execution, and clear communication as part of the company culture.
