Principal / Sr. Principal PCB Layout Design Engineer

We need to output HTML fragment with sections: About the role, Responsibilities, Requirements, Qualifications, Skills, Benefits, Pay, Schedule. Only include sections that have real specific content. We must not repeat job title. No Job ID etc. Remove boilerplate. We need to parse the posting. First, we have a description paragraph about Northrop Grumman, mission, etc. That could be "About the role" or maybe "About the company". The instruction says use headings like About the role, Responsibilities, Requirements, Qualifications, Skills, Benefits, Pay, Schedule. So we need to map content. We have description: "At Northrop Grumman, our employees have incredible opportunities..." That's about the company and role. Could go under About the role. Then responsibilities list: bullet list after "For this role, responsibilities include but are not limited to:" and then a long list of responsibilities (multiple lines). We'll put those under Responsibilities as

• . Then qualifications: Basic Qualifications for Principal and Sr. Principal. Also Preferred Qualifications. Those could go under Requirements and Qualifications? The instruction separate Requirements and Qualifications. Usually Requirements = basic qualifications, Qualifications = preferred? But we can decide. We'll put basic qualifications under Requirements, and preferred qualifications under Qualifications (or Skills?). There's also Skills section: maybe we can put preferred qualifications under Skills. But we need to follow headings: About the role, Responsibilities, Requirements, Qualifications, Skills, Benefits, Pay, Schedule. We have Pay info: Primary Level Salary Range and Secondary Level Salary Range. Also mention overtime, shift differential, discretionary bonus, annual bonuses, Long Term Incentives for VP/Director. That's pay details. So we can put under Pay. Benefits: mention health insurance, life and disability insurance, savings plan, company paid holidays and paid time off (PTO). Also relocation assistance mentioned at top: "RELOCATION ASSISTANCE: Relocation assistance may be available". Also maybe other benefits. So Benefits section. Schedule: mention "This position will require on‑site work at the Woodland Hills, CA facility." Also maybe travel: "TRAVEL: Yes, 10% of the Time". Also clearance: "CLEARANCE REQUIRED FOR START: No CLEARANCE TYPE: Top Secret". That could be under Requirements? But schedule maybe includes travel percentage. We'll put schedule: on-site work, travel 10% of time. Also maybe mention willingness to work on-site full-time. We need to avoid filler like "commensurate with experience". Not present. We must not include boilerplate like EEO, equal opportunity, scam warning, application instructions, etc. Also remove duplicated lines. We need to preserve all substantive information. Let's extract content. First, About the role: The paragraph(s) describing the role and company.

We can keep that as About the role. Responsibilities: list after "For this role, responsibilities include but are not limited to:" then bullet points: - Execute the placement and routing of complex, high‑density, multi‑layer printed circuit boards (PCBs), including high‑speed digital, RF, mixed‑signal, and power circuits - Interpret electrical schematics, constraints, and mechanical boundaries to develop optimized PCB layouts that meet performance, reliability, and manufacturability requirements - Generate and maintain complete PCB and circuit card assembly (CCA) fabrication and assembly documentation packages, including artwork, drawings, fabrication notes, and data outputs for procurement and assembly partners - Apply current IPC and high‑reliability industry standards, as well as applicable military and aerospace criteria, in the design and verification of printed wiring boards and circuit card assemblies - Collaborate closely with electrical, mechanical, manufacturing, and signal integrity engineers to address layout‑related design challenges involving signal integrity, power integrity, thermal management, and packaging - Support and perform Design for Manufacturing (DFM), Design for Assembly (DFA), and Design for Test (DFT) reviews using automated and manual checks to improve yield, test coverage, and product robustness - Work with fabrication and assembly suppliers to understand manufacturing capabilities and constraints and incorporate them into PCB designs - Support PCB library management practices, ensuring correct use of symbols, footprints, and parameter data in accordance with internal workflows - (Principal) Independently own PCB layout tasks from concept through fabrication data release in support of program cost, schedule, and technical requirements - (Sr. Principal) Lead advanced PCB layout efforts using technologies such as High‑Density Interconnect (HDI), microvias, via‑in‑pad, backdrilling, and specialized substrate materials; provide technical guidance, peer reviews, and mentoring to other layout designers We'll put each as
• . Requirements: Basic Qualifications for Principal and Sr. Principal. They share many items. We'll combine? Might list them as bullet points. Since they are similar, we can list the common requirements and note differences? But we must preserve all substantive info; we can list both sets. Basic Qualifications for a Principal PCB Layout Design Engineer (T03): - Bachelor’s degree in an engineering discipline with 5 years of engineering experience in an aerospace or closely related environment; or Master’s degree in an engineering discipline with 2 years of relevant experience - Ability to obtain and maintain a TS/SCI clearance - Willingness and ability to work on‑site full‑time at the Woodland Hills, CA location - Minimum 3 years of experience performing engineering/layout of printed circuit boards using Cadence Allegro or a closely related enterprise PCB layout tool - Experience with the layout of multi‑layer, high‑density PCBs and circuit card assemblies, including placement and routing of high‑speed digital, RF, and/or mixed‑signal circuits - Experience collaborating with diverse stakeholders across organizations and programs, including electrical design, mechanical design, manufacturing, test, and/or signal integrity - Working knowledge of PCB fabrication and assembly processes, including common manufacturability and yield considerations - Familiarity with IPC industry standards for PCB design and fabrication and current understanding of high‑reliability criteria - Experience generating artwork and PCB/CCA documentation for procurement and assembly houses - Excellent organizational and problem‑solving skills with a demonstrated ability to adapt effectively to changing requirements Basic Qualifications for a Sr. Principal PCB Layout Design Engineer (T04): - Bachelor’s degree in an engineering discipline with 8 years of engineering experience in an aerospace or closely related environment; or Master’s degree in an engineering discipline with 6 years of relevant experience; or PHD in an engineering discipline with 4 years of relevant exterience (typo: experience) - Ability to obtain and maintain a TS/SCI clearance - Willingness and ability to work on‑site full‑time at the Woodland Hills, CA location - Minimum 3 years of experience performing engineering/layout of printed circuit boards using Cadence Allegro or a closely related enterprise PCB layout tool - Experience with the layout of multi‑layer, high‑density PCBs and circuit card assemblies, including placement and routing of high‑speed digital, RF, and/or mixed‑signal circuits - Experience collaborating with diverse stakeholders across organizations and programs, including electrical design, mechanical design, manufacturing, test, and/or signal integrity - Working knowledge of PCB fabrication and assembly processes, including common manufacturability and yield considerations - Familiarity with IPC industry standards for PCB design and fabrication and current understanding of high‑reliability criteria - Experience generating artwork and PCB/CCA documentation for procurement and assembly houses - Excellent organizational and problem‑solving skills with a demonstrated ability to adapt effectively to changing requirements We can combine as Requirements (basic). Might note that Sr. Principal requires higher experience/education. Qualifications: Preferred Qualifications list. Preferred Qualifications: - Experience with signal integrity or power integrity analysis tools and workflows - Experience supporting environmental qualification and reliability test campaigns from a PCB layout perspective - Prior experience on defense or space flight programs with stringent reliability, documentation, and traceability requirements - Minimum 6+ years of experience performing engineering/layout of printed circuit boards using Cadence Allegro or a closely related enterprise PCB layout tool - Demonstrated expertise in the layout of advanced, high‑density, multi‑layer (typically 24+ layers) printed circuit boards combining RF, high‑speed digital, and high‑power circuit sections - Knowledge of PCB process workflows and library management, including creation and governance of symbols, footprints, and reusable layout elements - Experience implementing advanced manufacturing technologies, including High‑Density Interconnect (HDI), microvias, via‑in‑pad, backdrilling, and specialized substrate materials - Proven experience conducting comprehensive DFM, DFA, and DFT reviews using automated tools and collaborating with manufacturing and test partners to maximize manufacturing yields and test coverage - Experience providing technical guidance, layout reviews, and skill‑development mentorship to junior and mid‑level layout designers - Ability to translate complex mechanical boundaries and electrical constraints into optimized physical PCB layouts across multiple boards or modules - Deep domain knowledge of high‑reliability military and aerospace hardware criteria (e.g., MIL‑PRF‑31032, MIL‑STD‑883, IPC Class 3/3A), or comparable experience demonstrating equivalent rigor We can put these under Qualifications. Skills: Could be overlapping with Preferred Qualifications. But we might put some skill-specific items under Skills, like "Experience with signal integrity or power integrity analysis tools and workflows", "Knowledge of PCB process workflows and library management", etc. However we already have Qualifications. Perhaps we can treat Qualifications as preferred qualifications and Skills as technical skills like "Cadence Allegro", "IPC standards", etc. But we already have those in Requirements. To avoid duplication, we could decide to put Preferred Qualifications under Qualifications, and maybe Skills section could be empty? But instruction: include a section ONLY when the posting has real, specific content for it. So if we don't have distinct content for Skills, we should omit it. However we have some skill items that are not captured elsewhere? The Preferred Qualifications already cover many skills. Could we treat Qualifications as the preferred qualifications and not have a separate Skills section? That would be okay. But we have Requirements (basic qualifications) and Qualifications (preferred). That seems fine. Now Benefits: Include relocation assistance, health insurance, life and disability insurance, savings plan, company
