Astrodynamics and Navigation Engineer III

We need to output HTML fragment with sections: headings using

for sections like About the role, Responsibilities, Requirements, Qualifications, Skills, Benefits, Pay, Schedule. We must include only sections that have real specific content. We need to parse the job posting. First, identify sections: - About the role: description of role, mission, impact. The posting includes "Who We’re Looking For" and description. Could be "About the role" or "Responsibilities". We need to decide. We have responsibilities: "Lead mission design activities for LEO, MEO, GEO, and cislunar missions, including: ..." plus list of tasks. We have requirements/qualifications: "What It Takes:" bullet list: Bachelor’s degree, 5-10+ years experience, strong background, experience with tools, language, analytical skills, communication. Nice-to-Have: separate maybe "Preferred Qualifications" or "Skills". Could be "Skills" section. Benefits: "What You’ll Get" includes ownership, innovation, impact, growth, compensation – includes benefits: Competitive salary, equity, comprehensive benefits including medical, dental, vision, generous leave, HSA, 401(k) matching, and equity sharing. Also location and base salary range. Pay: Base Salary: $125,000 - $175,000. Also mention equity. Schedule: Not mentioned. So we should not include Schedule section. We need to avoid boilerplate: remove "Apply now. Join us in building the next generation of spacecraft." Also remove "Additional Requirements" about ITAR? That is a requirement (citizenship). Should we include? It's a requirement; we can include under Requirements/Qualifications. It's substantive. We must not repeat job title as heading. No Job ID. We need to preserve all substantive information. We need to use

for section headings. Use

• for any list of duties/requirements/benefits. Use

  for prose. We need to decide sections: maybe About the role (overview), Responsibilities, Requirements, Qualifications (maybe combine), Skills (nice-to-have), Benefits, Pay. But we must not create sections with filler. Ensure each heading has content. Let's extract content: About the role: Could be the introductory paragraph: "Quantum Space is redefining mobility and maneuverability in space. Our high-mobility spacecraft platforms support national security, civil, and commercial missions with unmatched flexibility and propulsion capability. We build fast and iterate quickly. Who We’re Looking For We are seeking an experienced Astrodynamics and Navigation Engineer III to lead the analysis, design, and operational support of highly maneuverable spacecraft missions. This role will lead trajectory design, orbit determination, maneuver planning, and mission analysis efforts across the mission lifecycle — from early concept development through on-orbit operations. You will work closely with systems engineering, GNC, flight software, propulsion, and mission operations teams to develop and implement robust, high-fidelity flight dynamics capabilities that support trajectory design, orbit determination, maneuver planning, and mission analysis for missions across multiple regimes." That's a good overview. Responsibilities: The bullet list after "Where You’ll Make an Impact Lead mission design activities for LEO, MEO, GEO, and cislunar missions, including:" then list items separated by commas? Actually it's a long sentence with colon then list separated by commas? Let's parse: "Lead mission design activities for LEO, MEO, GEO, and cislunar missions, including: Trajectory and maneuver design Delta-v/propellant budgeting Orbit maintenance planning Navigation covariance sensitivity studies Launch injection dispersion and maneuver execution Monte Carlo analyses Disposal planning Own mission-level simulation and end-to-end performance analysis, including: Eclipse & payload coverage analyses Conjunction assessment and collision avoidance analysis Ground station visibility analysis and link budget inputs Tracking geometry assessment and schedules Scheduling support for mission operations Architect navigation solutions, informing selection of spacecraft tracking measurement phenomenologies and ground networks Develop and maintain internal flight dynamics and mission analysis tools (Python/MATLAB/C++-based) Contribute to spacecraft operations, including maneuver planning, anomaly investigation and on-orbit performance evaluation Generate technical documentation, trade studies, and design reports Collaborate with GNC, communications, systems engineering, mission operations" We can treat each line as a responsibility item. Requirements/Qualifications: "What It Takes:" then bullet list: - Bachelor’s degree in Aerospace Engineering, Astrodynamics, Physics, or related field - 5-10+ years of experience performing mission design tasks, general mission analysis, and flight dynamics related operations for spacecraft systems - Strong background in orbital mechanics, spacecraft dynamics, and spacecraft navigation - Experience with industry standard tools such as Systems Tool Kit (STK)/Orbit Determination Toolkit (ODTK), Freeflyer, GMAT, or similar - Experience in at least one of the following languages: Python, MATLAB - Strong analytical and problem-solving skills - Excellent written and verbal communication skills Also Additional Requirements: "To comply with U.S. Government space technology export regulations, including ITAR, applicants must be a U.S. citizen, lawful permanent resident, protected individual per 8 U.S.C. 1324b(a)(3), or eligible to obtain the required authorizations from the U.S. Department of State." We can include that as a requirement. Nice-to-Have (Skills): "Nice-to-Have Experience:" bullet list: - Master’s degree in Aerospace Engineering with a focus in Astrodynamics or Estimation - Experience with cislunar three-body trajectory design and navigation - Experience with Rendezvous and Proximity Operations (RPO) mission design including relative orbit design and navigation - Experience designing low-thrust and hybrid propulsion spacecraft missions - Experience with alternative forms of spacecraft navigation (e.g. OpNAV, inter-satellite links) - Exposure to other spacecraft subsystems (e.g. GNC, propulsion, FSW) We could put under "Skills" or "Preferred Qualifications". Use heading "Skills" maybe. Benefits: "What You’ll Get" includes ownership, innovation, impact, growth, compensation – but also includes "Competitive salary, equity, and comprehensive benefits including medical, dental, vision, generous leave, HSA, 401(k) matching, and equity sharing." Also location and base salary. We could separate Benefits (non-monetary) and Pay (salary). Benefits: Ownership, Innovation, Impact, Growth (these are more like value propositions). But the instruction says use Benefits section for benefits. The posting includes "What You’ll Get" which includes ownership, innovation, impact, growth, compensation. Could treat as Benefits section with bullet list of those items. However "Ownership – Build and validate..." etc are more like value propositions. Might be okay. Pay: Base Salary: $125,000 - $175,000 plus mention equity. We should not include filler like "commensurate with experience". Not present. We need to avoid duplication. Now produce HTML:

  About the role

  Quantum Space is redefining mobility and maneuverability in space. Our high-mobility spacecraft platforms support national security, civil, and commercial missions with unmatched flexibility and propulsion capability. We build fast and iterate quickly.

  But note nested lists: we could flatten but it's okay. However spec says use
  • for any list of duties/requirements/benefits. Nested lists still okay. Alternatively we could just list each bullet as top-level items, but we need to preserve grouping. Might be okay. Now Requirements:
