LEAD ENGINEER - PRINCIPAL ENGINEER - Avionics Thermal Design Engineer

SWRI

San Antonio, TX • On-site

Full-time

Re-posted 17 days ago


Job description

  • Lead thermal architecture for advanced avionics, ensuring electronics meet performance and reliability targets across worst-case mission environments (hot ramp, cold soak, high altitude).
  • Deliver flight-worthy, integratable thermal designs (conduction, convection, liquid/air cooling) that reduce risk, rework, and schedule impacts during integration and test.
  • Own end-to-end analysis and validation (CFD/FEA, derating, margins, qualification) to prove compliance with customer/airworthiness requirements and program commitments.
  • Drive DMSMS-aware modernization by selecting COTS/MIL-spec components and thermal solutions that improve sustainment, maintainability, and lifecycle cost.
  • Mentor teams and set technical standards for thermal design reviews, test readiness, and production transition, accelerating delivery of high-confidence avionics solutions.

  • Lead thermal trade studies for avionics (air/liquid cooling, conduction paths, materials), set margins, and resolve heat/airflow issues with electrical, mechanical, and systems teams.
  • Build/update CFD/FEA models, power maps, and derating analyses; document assumptions, sensitivities, and results to support rapid design decisions and integration readiness.
  • Support lab bring-up and troubleshooting-instrumentation, data review, root-cause of hot spots, and corrective actions for hardware and packaging changes.
  • Plan/execute thermal verification (TVAC/temperature rise, airflow tests), define test procedures, analyze results, and produce compliance evidence for reviews and airworthiness artifacts.
  • Drive design reviews and configuration control-approve drawings/BOM impacts, coordinate suppliers, and mentor engineers on thermal standards, best practices, and lessons learned.

  • Requires a Bachelors degree in Mechanical Engineering, Thermal Engineering, Mechatronics Engineering or related engineering degree with directly related experience.
  • 11+ years: Expert thermal engineering for avionics: heat transfer, thermal networks, component derating, and margining across flight and ground extremes; strong fundamentals plus practical packaging insight.
  • 11+ years: Advanced analysis skills: CFD/FEA (e.g., Flotherm/Icepak/ANSYS), model correlation, uncertainty/sensitivity studies, and turning results into clear design decisions and requirements.
  • 11+ years: Requirements-to-results driver: translate customer thermal/performance requirements into actionable design constraints, lead trades to meet SwRI design standards, and deliver verified thermal margin with clear compliance evidence.
  • 11+ years: Systems integration skills: partner across EE/ME/SE, manage interfaces and configuration, drive technical reviews, mentor engineers, and communicate effectively with customers and program leadership.
  • A valid/clear driver's license is required.
