Senior Antenna & RF Hardware Engineer

We need to output HTML fragment with sections: About the role, Responsibilities, Requirements, Qualifications, Skills, Benefits, Pay, Schedule. Only include sections with real specific content. Need to extract content from posting. We must not repeat job title as heading. No Job ID. Remove boilerplate, EEO, etc. Keep substantive info. We need to decide sections. Let's parse posting: Intro about Hubble Network: description of company, mission. Could be "About the role" maybe? Actually "About the role" is typical heading for description of role. The posting includes description of role responsibilities etc. We can treat "About the role" as a paragraph summarizing role. Then "Responsibilities": list of duties: lead design of phased-array antennas and RF receive chains; define array architecture; perform EM simulation; own schematic design and PCB layout; execute antenna and RF characterization campaigns; accountable for performance budgets; involved in all aspects of hardware product from definition, development, implementation, testing and production; work with cross-functional groups on hardware-software integration and test, verify, and document the flight payload. "Requirements" maybe "Basic Qualifications": list of qualifications: Bachelor's (Master's preferred) in EE, CE, or related; 10+ years professional experience in antenna and RF design, including multiple antenna designs carried personally from concept through fabricated and characterized hardware; Demonstrated phased-array antenna design experience, including ownership of array and element spacing, embedded element pattern behavior, mutual coupling and active reflection coefficient, grating lobe and scan volume trades, and array calibration. Single-element antenna design experience alone is not sufficient; Expertise with full-wave EM solver; Direct experience with antenna measurement and characterization; Strong understanding of RF design principles; Demonstrated receiver front-end design experience for sensitivity-limited systems; Experience with LO generation and distribution; Hands-on RF bring-up, tuning, debug, and test experience; Expertise in PCB design and layout of high-frequency RF circuits in Altium Designer; Proficiency with Python or MATLAB; Strong technical writing ability; Strong interpersonal, verbal, and written communication skills; Ability and willingness to thrive in fast-paced environment. "Qualifications" maybe "Strongly Desired": list of desired: Experience planning or supporting EMI/EMC test campaigns; Experience in design of antennas and RF systems for space or aerospace applications including material selection and outgassing, thermal cycling and radiation effects; Working knowledge of NASA and MIL-spec requirements; Working knowledge of EMI/EMC design and compliance; Familiarity with radio regulatory compliance; Familiarity with digital beamforming architectures; Experience with wireless IoT network protocols such as BLE and Zigbee; Experience mentoring junior engineers or serving as technical lead. "Skills": maybe combine some of the above? But we can keep separate sections: Requirements (basic qualifications) and Qualifications (strongly desired). Or we could treat "Skills" as technical skills list. "Benefits": list: Comprehensive Benefits – Health, Dental, Vision, & HSA options; Unlimited PTO; Commuter Benefits (if working from HQ); Learning & Development Allowance; Health & Wellness Stipend; Sabbatical Program; Cutting-Edge Space Tech – Work on state-of-the-art satellite system. "Pay": Salary: $101,000-177,000 (commensurate with experience). The instruction says: never create Pay/Schedule/Benefits sections unless the posting actually states them. It does state salary range, so we can include Pay section. However they also say avoid filler like "commensurate with experience" maybe considered filler? It says: never emit a heading followed by filler/placeholder text (e.g. "commensurate with experience", "not specified", "N/A", "varies", "TBD"). So we should not include that phrase if it's just filler. But the salary range is given; we can present as "$101,000–$177,000". The phrase "commensurate with experience" is filler; we should omit it. So Pay section:

$101,000–$177,000

. "Schedule": The posting says: This is a HYBRID, FULL-TIME position based in Seattle, WA. So schedule: Hybrid, Full-time. That's specific. So we can include Schedule section with that info. "About the role": Could be a paragraph summarizing role: Senior Antenna & RF Hardware Engineer to lead design of phased-array antennas and RF receive chains deployed on Hubble's satellite payloads. Also mention company mission maybe. We'll include that. We must not repeat job title as heading. So we won't have heading "Senior Antenna & RF Hardware Engineer". We'll just have sections. We need to output only HTML fragment, no /, no markdown fences. We'll produce something like:

Skills

Maybe we can combine some skills like proficiency with Python/MATLAB, Altium Designer, etc. But many are already in Requirements. Could omit Skills if redundant. But we need to decide. Given instruction: Prefer a few substantive sections over many thin ones. So maybe we combine Requirements and Qualifications into one "Requirements" section? But they are distinct: basic vs strongly desired. Could keep both. Skills could be omitted if covered. But we need to include Benefits, Pay, Schedule sections. Let's craft content. About the role paragraph: Summarize: Hubble Network is building a global Bluetooth® network dedicated to machine-to-machine connectivity, first modem-less and gateway-less direct-to-satellite network using off-the-shelf BLE chips. As Senior Antenna & RF Hardware Engineer, you will lead the design of phased-array antennas and RF receive chains for Hubble's satellite payloads, defining array architecture, performing EM simulation, owning schematic and PCB layout, executing characterization campaigns, and ensuring performance budgets, working end-to-end from definition to production, collaborating with cross-functional teams on hardware-software integration, test, verification, and documentation. That's substantive. Responsibilities bullet list: - Define phased-array antenna architecture and payload antenna subsystem (PAS) panels. - Perform electromagnetic simulation and analysis using HFSS, CST, or FEKO. - Own schematic design and PCB layout implementation in Altium Designer through release to fabrication. - Execute antenna and RF characterization campaigns (anechoic chamber, near-field/far-field, gain/efficiency). - Account for performance budgets governing the design (link budget, antenna aperture, front-end). - Involved in all hardware product phases: definition, development, implementation, testing, and production. - Work with cross-functional groups on hardware-software integration, test, verification, and documentation of flight payload.

We must not include filler like "commensurate with experience". Already omitted. We must not include duplicated lines. Ensure no repetition. Now produce HTML fragment. Check for any headings that might be empty: All sections have content. We should not include

for Pay and Schedule? The instruction says use

for section headings (e.g. About the role, Responsibilities, Requirements, Qualifications, Skills, Benefits, Pay, Schedule). So yes, use

for Pay and Schedule as well. Thus:
