Sr. RF and Wireless Systems Engineer, Amazon Leo Digital RF Systems
for section headings. Use - for any list of duties/requirements/benefits. Use
for prose.
We need to preserve all substantive info; do not invent or summarize away detail. So we need to keep details like specific tools, specific responsibilities bullet points, qualifications bullet points, benefits details, salary ranges.
We must not include boilerplate like EEO, equal opportunity, scam warning, navigation, cookie, legal, etc. Also remove Los Angeles County specifics? That is likely boilerplate/local law; but it's substantive? It mentions criminal history etc. Might be considered boilerplate but it's location-specific. The instruction: Remove cookie/navigation/legal/EEO/equal-opportunity/scam-warning boilerplate, duplicated lines, and application instructions. The Los Angeles County section includes legal stuff; likely considered boilerplate. We'll drop it.
Also remove "Export Control Requirement" maybe not boilerplate; it's a requirement. Keep.
We need to ensure we don't duplicate lines.
Let's extract sections.
About the role: combine first paragraph description and "The Role" paragraph.
Prose: "Amazon Leo is Amazon’s low Earth orbit satellite network. Our mission is to deliver fast, reliable internet connectivity to customers beyond the reach of existing networks. From individual households to schools, hospitals, businesses, and government agencies, Amazon Leo will serve people and organizations operating in locations without reliable connectivity.
As a Sr. RF and Wireless Systems Engineer in the Digital RF Systems team, you will be responsible for RF architecture definition, RF line-up design, and RF specifications of custom ASICs used in Leo phased array systems. You will work closely with RFIC and DSP designers during the design phase, participating in RFIC design reviews to ensure optimal system-level RF performance. You will use MATLAB, ADS and other simulation tools to model RF impairments of the chips and analyze complex phased array system and sub-system interactions. In post-silicon, you will be involved in prototyping, defining RF DVT lab test requirements to validate designs. You will support production teams through statistical analysis and yield optimization in cross-functional collaboration with manufacturing engineers. You will develop novel techniques to estimate and correct RF impairments such as IQ imbalance, LOFT implemented in hardware and firmware. Based on system-level constraints such as low power and cost, you will develop optimized solutions to support high throughput for our customers. You will engage with an experienced cross-disciplinary staff to conceive and design innovative product solutions, working closely with internal teams including ASIC/RFIC designers, firmware/software engineers, and design verification engineers. You will drive key aspects of wireless product design identifying ASIC level specifications from the product requirements."
That's a lot; we can keep as prose.
Responsibilities: list from "Key job responsibilities". Let's extract bullet points:
- Own end-to-end RF architecture and line-up design for the Leo RFICs and phased array communication systems used in the satellites and customer terminals
- Define RF specifications, key performance requirements for custom ASIC development
- Simulate and characterize RF impairments impact on the system
- Review RFIC designs for compliance with system performance targets
- Research and implement calibration and correction algorithms for RF front-end impairments
- Involve in lab validation plans for post-silicon RF characterization
- Identify and resolve RF performance bottlenecks through measurements and analysis
- Balance power, cost, and throughput trade-offs to meet product requirements
- Support ASIC production data reviews to drive yield improvements with manufacturing engineering
- Serve as the RF systems point of contact across silicon design, firmware, software, and test teams
We'll put each as
- .
Requirements: Basic Qualifications plus Export Control Requirement.
Basic Qualifications bullet list:
- Master's degree or Ph.D. degree in Electrical Engineering or related field
- 7+ years of relevant experience in wireless DSP/RF systems engineering (LTE, 5G-NR, WiFi 802.11, BLE)
- In depth knowledge of RF architectures and design for low power consumption RFIC and ASIC
- Solid understanding of RF blocks and components, RF simulation tools
- Experience in RF impairment estimation and compensation techniques
- Working knowledge of FW implementation of various DSP algorithms for RF impairment compensation
- Experience in using lab equipment, bring-up and validation of chip
- Experience with MATLAB, Python and/or C/C++ for fixed point DSP algorithm development, RF impairment modeling and simulation
- MSEE/PhD is highly preferred with emphasis on RF systems, mmWave RFIC designs
Export Control Requirement: "Due to applicable export control laws and regulations, candidates must be a U.S. citizen or national, U.S. permanent resident (i.e., current Green Card holder), or lawfully admitted into the U.S. as a refugee or granted asylum."
We can include as a paragraph under Requirements.
Qualifications: Preferred Qualifications bullet list:
- Strong background in RFIC design process
- Digital/Wireless Communication Systems and engineering
- Experience in designing low power/area digital signal processing blocks for Wireless RF SOCs
- Excellent understanding of RF architectures and blocks used in the Wireless SOCs
- MATLAB, Python, C++ experience with emphasis on fixed point modeling of DSP blocks, RF impairment modeling, RF calibration algorithm development, system performance simulations (EVM, ACLR, OOB emissions)
- Familiarity with phased array systems and phased array performance optimization techniques
- Experience in silicon bring-up in the lab and using lab equipment such as vector spectrum analyzer, signal generators, high speed scopes and logic analyzers
- Proficiency in Ansys HFSS and Keysight ADS simulation tools
Skills: Could be derived from qualifications but we might combine. However we could create a Skills section summarizing technical skills: MATLAB, ADS, HFSS, Python, C/C++, fixed-point DSP, RF impairment modeling, calibration algorithms, lab equipment, etc. But we must not invent; we can pull from qualifications. Since we already have qualifications sections, maybe we skip Skills to avoid thin sections. But we need to decide: The instruction: Prefer a few substantive sections over many thin ones. So we could merge Skills into Qualifications or Responsibilities. However they asked to use headings for Skills if posting has real specific content. The posting does list skills implicitly in qualifications. Could we create a Skills section that lists specific technical skills (MATLAB, ADS, HFSS, Python, C/C++, lab equipment, etc.)? That would be substantive and not thin. But we already have qualifications that list similar items; might be duplication. Better to keep Qualifications (both basic and preferred) and maybe Skills not needed. However the instruction says use headings for Skills if posting has real specific content. It does not forbid having both Qualifications and Skills; but we should avoid thin sections. If we make Skills, we need to ensure it's substantive. Could list: MATLAB, ADS, HFSS, Python, C/C++, fixed-point DSP algorithm development, RF impairment modeling, calibration algorithms, lab equipment (vector spectrum analyzer, signal generators, high-speed scopes, logic analyzers), RFIC design process, low-power DSP blocks, phased array optimization. That's substantive.
But we already have those in qualifications; duplication might be okay but could be considered repetitive. The instruction: "Preserve ALL substantive information; do NOT invent or summarize away detail." Duplication is not prohibited but might be unnecessary. However we can keep Qualifications as is and not add Skills to avoid redundancy.
Benefits: The posting mentions base salary range, sign-on payments, RSUs, comprehensive benefits including health insurance (medical, dental, vision, prescription, Basic Life & AD&D insurance and option for Supplemental life plans, EAP, Mental Health Support, Medical Advice Line, Flexible Spending Accounts, Adoption and Surrogacy Reimbursement coverage), 401(k) matching, paid time off, parental leave. Also link to benefits.
We need to capture all that.
Pay: base salary range for locations: USA, CA, San Diego - 185,200.00 - 250,000.00 USD annually; USA, WA, Redmond - 185,200.00 - 250,000.00 USD annually.
We could put Pay section with those ranges.
Schedule: none.
Thus sections: About the role, Responsibilities, Requirements, Qualifications, Benefits, Pay.
We need to ensure we don't include headings with empty content.
Now format.
We'll output:

Now craft prose for About the role: combine description and The Role paragraph. Ensure we keep all details.
