RF Engineer - Sacramento, CA

Engineer I

• Implement and test simple RF building      blocks (filters, couplers) from established schematics.
• Run directed simulations (ADS/HFSS/CST); document results and perform basic parameter sweeps.
• Execute bench measurements using VNAs      and spectrum analyzers; record first-order data.
• Support BOM creation and EOL data      gathering.
• Collaborate with mechanical/software      teams on interface details.
• Collect and organize test data      accurately, perform basic trend analysis, and prepare clear charts and      summary reports under guidance. 

Engineer II

• Iterate LNAs/PAs and mixer front ends designs; address biasing, stability, and matching networks.
• Perform simulations; correlate model-to-measurement; refine designs to meet gain, NF, and linearity.
• Develop and execute test plans; interpret results to drive corrective actions.
• Partner with manufacturing on      thin-film/PCB/box-build considerations; incorporate DFM/DFT feedback.
• Create accurate BOMs with alternates; assist with EOL analysis.
• Proficient in analyzing RF      performance data (gain, noise figure, linearity) and correlating results      with simulation outputs. Capable of generating structured reports that      include observations, root-cause hypotheses, and recommended corrective      actions for review by senior engineers.

Engineer III (Senior)

• Architect and lead subsystem designs (up/down-converters, mixers, synthesizers); balance gain, NF, linearity, spurious, and thermal stability.
• Own model-to-hardware correlation; employ EM/circuit co-simulation and statistical analyses.
• Direct rigorous validation using VNAs, spectrum analyzers, and custom fixtures; interpret complex data.
• Lead manufacturability integration; manage NPI transitions and reliability/yield tradeoffs.
• Perform EOL analysis; select      replacements and manage compliance impacts.
• Interpret complex RF test datasets      and simulation results to validate subsystem performance. Prepare      comprehensive technical reports for internal design reviews, and customer      review meetings.
• Mentor junior engineers and lead      design reviews.

Engineer IV (Staff/Principal)

· Define and oversee RF product architectures and integration into complete systems.

· Lead advanced RF design efforts for converters, amplifiers, and complex thin-film circuits; resolve multi-physics/EM interactions.

· Establish performance optimization frameworks and acceptance criteria; mentor teams to those standards.

· Innovate in simulation/modeling; codify best practices/tool flows.

· Direct complex validation campaigns; adjudicate data for architecture-level decisions.

· Drive manufacturability/reliability strategies across thin-film, PCB, and box-build; partner with Operations.

· Own component lifecycle management and BOM standards; review high-impact bids.

· Act as technical liaison across mechanical/software; represent engineering in major customer/executive reviews.

· Produces executive-ready/customer-facing technical reports and white papers that articulate design trade-offs, risk assessments, and compliance impacts. Sets standards for data integrity and reporting practices across engineering teams.

· Guide adherence to government contract flow-downs and export controls; help scope Technical Assistance Agreements.
