: RF Electrical Engineer (systems architecture and radar) 23-I

Job Title: RF Electrical Engineer (systems architecture and radar)

Location: Cambridge, MA 02142 onsite

Experience level: 7-10 years

Skills:

• 7+ years of RF experience in radar hardware development, including defining requirements, schematic design, layout, and overseeing the manufacturing of PCBAs.

• Experience with radar design - i.e. translating FCC requirements into design specifications, link budget analysis, impact of antenna geometry on gain pattern.

• Experience with schematic design and layout - i.e. component selection, placement, feedline routing, impact of via/trace geometries on insertion loss.

• Manufacturing - Interface with PCB fab and assembly shops; Define the stackup; Anticipate and identify design issues that would impact manufacturing reliability. • Comfortable bringing-up and testing radar boards using oscilloscopes, spectrum analyzers, horns, and probes.

• Comfortable using Altium, our PCB CAD tool.

• Comfortable guiding other engineers to run Ansys HFSS, interpreting the results, and providing advice on how to adjust geometries to improve performance.

• Digital circuit design and layout, with a skill to layout and isolate high-frequency (up to 30 Ghz) traces.

• Experience with Xilinx and Intel Altera FPGAs

• Able to independently collect and analyze data to innovate and improve the performance of radar-based hardware and associated analogue and digital circuitry

• Able to work collaboratively with RF engineers on analog electrical engineering tasks and challenges.

• Able to work collaboratively with a range of external third parties and vendors.

Additional Qualifications:

• High attention to detail with strong written and verbal communication skills and technical documentation

• Creative thinking and problem solving

• Strong communication and teamwork skills • The following skills are also highly desirable:

• working knowledge of radar products, commercial acumen,

• experience with novel product design,

• Master’s degree preferred or with equivalent work experience

Responsibilities:

• Understand the commercialization objectives and how they influence hardware choices.

• To lead and manage the component and module selection effort.

• Design and layout those components with complex multi-layer PCBs mixing high frequency analog and digital components.

• Manage PCB fabrication and assembly.

• Communicate the radar’s theory of operation with our machine learning team.

• Collaboratively work with and coordinate RF engineers in the design of the Analog circuits and antennas
