Job summary
DAS Technology Group in California is seeking a driven RF engineer to design and validate RF subsystems, including converters, amplifiers, and thin-film circuits. You will implement RF blocks from schematics, run ADS/HFSS/CST simulations, and perform bench measurements with VNAs to verify performance.
The role spans from Engineer I to Senior levels, with increasing responsibility to lead subsystem design, model-to-hardware correlation, and liaison with manufacturing for NPI, BOMs, and EOL
Qualifications
- Bachelor’s degree in Electrical Engineering or related technical discipline is required.
- Experience with RF design, testing, and measurement is expected.
- Ability to interpret RF measurements and correlate with simulations; strong documentation skills.
Responsibilities
- Implement and test RF building blocks (filters, couplers) from schematics.
- Run directed simulations (ADS/HFSS/CST) and document results.
- Execute bench measurements using VNAs and spectrum analyzers; record data.
- Collaborate with manufacturing on BOMs, DFM/DFT concepts, and EOL considerations.
- Architect and lead subsystem designs (up/down-converters, mixers, synthesizers).
- Mentor junior engineers and participate in design reviews.

Job description
- 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.
- 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.
- 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.
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.
