Lead Avionics Engineer - Flight Termination System

We need to output HTML fragment with sections: About the role? Actually the posting includes "About Castelion" description, then job title, then responsibilities, qualifications, etc. We must not repeat job title as heading. Use

for section headings: About the role, Responsibilities, Requirements, Qualifications, Skills, Benefits, Pay, Schedule. We need to include sections only when posting has real specific content. We have: - About Castelion: description of company. That could be "About the role"? Actually "About Castelion" is company overview, not role. But we can map to "About the role"? The instruction says use

for section headings (e.g. About the role, Responsibilities, Requirements, Qualifications, Skills, Benefits, Pay, Schedule). So we should use those exact headings if content exists. For company overview maybe "About the role" could include description of role and company? The posting includes "About Castelion" which is about company. Could treat as "About the role" content: combine company description and role summary? The role summary is given after title: "As the Lead Avionics Engineer specializing in Flight Termination Systems (FTS), you will be responsible for the design, development, testing, and qualification of systems that ensure the safe termination of a flight if it deviates from its planned trajectory. You will work with both hardware and software components, as well as coordinating with various key stakeholders." That's a role summary. So we can put that under About the role. Responsibilities: we have a big list. Requirements: The posting has "Basic Qualifications" and "Preferred Skills And Experience". Also "Leadership Qualities". Also "ITAR Requirements". Also "All employees are granted long-term stock incentives..." etc. Those are benefits. We need to map to sections: Requirements (maybe basic qualifications), Qualifications (maybe preferred skills?), Skills (maybe leadership qualities?), Benefits (stock incentives, medical, PTO). Pay and Schedule: not mentioned, so omit. We must not include filler like "commensurate with experience". Not present. We must preserve all substantive info, not invent. We need to remove boilerplate: ITAR Requirements is substantive (citizenship requirement). Should we include under Requirements? Probably yes. Also EEO statement is boilerplate, remove. Also "All employees are granted long-term stock incentives as part of their employment at Castelion. All employees receive access to comprehensive medical, vision, and dental insurance, and the company offers four weeks of paid time off per year." That's benefits. We need to output only HTML fragment, no /, no markdown. We'll structure:

About the role

... company description + role summary ...

Responsibilities

• ... each responsibility ...

Requirements

We must not repeat job title. Ensure we preserve all details. Let's extract details. About Castelion paragraph: "Castelion is bringing a new approach to defense development and production: one that focuses on short, iterative design cycles, rapid testing in development, and modern commercial manufacturing strategies for production at scale. We're designing, building, and testing next generation long range strike weapons systems to give America and its Allies a definitive edge and deter future conflicts." Role summary: "As the Lead Avionics Engineer specializing in Flight Termination Systems (FTS), you will be responsible for the design, development, testing, and qualification of systems that ensure the safe termination of a flight if it deviates from its planned trajectory. You will work with both hardware and software components, as well as coordinating with various key stakeholders." Combine into one paragraph. Responsibilities list (bullet points). Let's copy each line: - Own system and electrical architecture development and integration of Flight Termination System components (RF command interfaces, control boxes, electronic safe and arm devices, initiators, and destruct charges) for the Blackbeard vehicle. - Define detailed system design, including component selection, system interconnect schematics, RF interfaces, consumable budgets, harness and channel capabilities, fault tolerance, and reliability. - Execute system validation, including compatibility testing with range assets, system electrical testing in HITL, and flight test qualification. - Collaborate closely with regulatory partners and Range Safety to develop and maintain a tailored set of requirements specific to the Blackbeard program that defines FTS certification. - Design and analysis of safety-critical circuits for ordnance initiation and command destruct receivers. - Define test plans, processes, fixturing, test sequences, and generate technical reports to show compliance to strict regulatory standards. - Lead qualification and acceptance testing of components under rigorous test environments (shock, vibration, thermal cycle, etc.) that validate component reliability and functionality. - Conduct analyses to support reliability data and reduced scope of testing - Generate and maintain detailed system & component documentation and specifications - Act as the technical expert for the overall system and piece-part components, leading component & system anomaly root cause investigations and with data-driven rationale to determine hardware disposition & corrective - Challenge applicability of baseline requirements through understanding the intent of the regulatory requirement versus solely the face value as-written requirement. - Act as the responsible engineer for flightworthiness of the Flight Termination System all the way through launch, validating the as-built system is a GO for launch. Note some lines have trailing incomplete text: "and with data-driven rationale to determine hardware disposition & corrective" maybe missing word. We'll keep as is. Basic Qualifications: - Bachelors degree in electrical engineering - 5+ years of experience with electrical component design, system level integration of electronic components, or system level testing Preferred Skills And Experience (list): - Strong interpersonal and collaborative skills, enthusiasm for problem solving, and desire to optimize modern defense production - 3+ years of experience designing and analyzing electrical systems via professional work experience, project/research-based student experience, or a combination of both - Strong background in RF link design and validation, including antenna integration, link budget analysis, and EMI/EMC mitigation for high-reliability environments. - Skilled in designing low-noise, isolated power supplies, DCDC converters, and battery management systems for mission-critical hardware. - Deep familiarity with U.S. range safety standards (AFSPCMAN 91710, RCC 319, NASA 8719) and certification processes with FAA/AST and DoD ranges. - Experience designing, integrating, and troubleshooting FTS hardware with flight avionics, telemetry, and ordnance devices, including safe-arm devices and separation mechanisms. - Hands-on leadership of vibration, thermal, shock, and EMI/EMC test campaigns per MILSTD810 and related aerospace standards. - Proficient in hardware-in-the-loop (HIL) testing, RF link verification, and fault injection testing for destruct command reliability. - Strong project management skills and effective communication of technical concepts across multi-disciplinary teams - Leadership experience on a project or research team - Knowledge of electro-mechanical devices, actuators, motors, or explosives - Understanding of fundamental principles of explosives, solid mechanics, and dynamics - Experience with system design and testing for hardware sub-systems such as RF, power, communications, and sensors - Familiarity with electrical test equipment (multimeters, oscilloscopes, power supplies, etc.), and basic analysis techniques - Experience writing engineering software for test automation, data review, and design analysis, preferably in MATLAB or Python - Excellent verbal and written communication skills Leadership Qualities (list): - Bias to Action and Creative Problem Solving.

We can include under Requirements as a bullet. Benefits: "All employees are granted long-term stock incentives as part of their employment at Castelion. All employees receive access to comprehensive medical, vision, and dental insurance, and the company offers four weeks of paid time off per year." We'll make bullet list. Now ensure we don't include any boilerplate like EEO etc. We removed. Now produce HTML. We'll need to escape any HTML special characters? The text includes parentheses, etc. It's fine. We'll output:
