Principal / Sr. Principal RF Design Engineer – Mixed Signal Packaging, EMC Analysis & Design

At Northrop Grumman, our employees have incredible opportunities to work on revolutionary systems that impact people's lives around the world today, and for generations to come. Our pioneering and inventive spirit has enabled us to be at the forefront of many technological advancements in our nation's history - from the first flight across the Atlantic Ocean, to stealth bombers, to landing on the moon. We look for people who have bold new ideas, courage and a pioneering spirit to join forces to invent the future, and have fun along the way. Our culture thrives on intellectual curiosity, cognitive diversity and bringing your whole self to work — and we have an insatiable drive to do what others think is impossible. Our employees are not only part of history, they're making history.

Northrop Grumman Mission Systems (NGMS) Advanced Capabilities division is leading the development of the next generation of high-performance computing. Superconducting electronics forms the core of our technology, with a focus on energy-efficient computation using our patented superconducting digital logic technology, Reciprocal Quantum Logic (RQL). On a gate-for-gate basis, RQL consumes orders of magnitude less power than CMOS while running at significantly higher clock speeds.

The Advanced Capabilities group is seeking experienced Principal / Sr. Principal RF Design Engineers - Mixed Signal Packaging, EMC Analysis & Design to develop these technologies into high-performance computing systems. You’ll work in a fast-paced team environment alongside physicists, design engineers, and superconducting foundry engineers to make these technologies a reality.

 How you will contribute to the Mission:

• Lead and/or contribute directly, working on design and analysis of signal integrity and electromagnetic effects in highly complex high frequency, high dynamic range mixed signal systems in a very collaborative and innovative research and development environment

• Perform analytical studies of electronic systems (integrated circuits, chip-level packaging, interposers, printed circuit boards, connectors, etc.) to support design tradeoffs

• Design and analysis activities include electromagnetic modeling (e.g. SSN, ISI, crosstalk, EMC/EMI) for packaging parasitic estimation, associated interconnect, PCBA and filters. All design, testing and verification efforts ensure simulated and measured results meet desired design targets, and continually improve simulation-measurement correlation

• Develop new test and simulation methods as necessary to support the above activities when demands exceed the state of the art

• Create new design strategies where possible to support functional requirements while meeting SI, PI and EM goals

• Deep understanding of RF/EMC measurement and analysis (s-parameters, eigenmodes, TDR, FFT, IF, etc.)

• Work closely with other domain experts performing related functional analyses (e.g. Mechanical design & analysis, circuit design & test, thermal analysis, etc.)

• Willingness to continually expand the knowledge base of yourself and the team (e.g. examine new research, relevant papers, seek applicable methodologies in adjacent applications, etc.)

• Coordinate related technical team activities

• Present details of work to colleagues during design reviews

• Create and manage work plans to meet or exceed schedule deadlines

• Provide written and oral summaries of work performed as needed (e.g. for reports)
