Principal Engineer, Controls

Systems Performance and Aerothermal Analyst Beehive Industries is dedicated to Powering American Defense by revolutionizing the design, development, and delivery of jet propulsion systems to support the warfighter. Through the integration of additive manufacturing, the company aims to meet the growing and urgent needs for unmanned aerial defense by dramatically improving a jet engine’s speed to market, fuel efficiency, and cost. Founded in 2020, the company is headquartered in Centennial, Colorado, with additional facilities in Knoxville, Tennessee, Loveland Ohio, and Mount Vernon, Ohio. Beehive is committed to grow and advance the defense industrial base while manufacturing exclusively in the USA. This role will be located at our Loveland, Ohio or Centennial, Colorado facility but can also be remote. Role Overview The Systems Performance /Aerothermal Analyst will sit within our Advanced Technical Programs (ATP) organization, where teams work at the leading edge of technology development to solve complex problems and rapidly mature new propulsion concepts. This role will focus on engine and system performance analysis across early-stage architecture studies, cycle modeling, fluid system analysis, and test data interpretation. The ideal candidate brings strong performance fundamentals, is fluent in Python, and can quickly work through design trade space using available cycle models and analytical tools. They should be comfortable evaluating engine architectures, modifying performance models, analyzing test data, and supporting 1D network modeling of fluid systems. This role is best suited for someone who is technically sharp, highly self-directed, and comfortable operating in ambiguity without requiring heavy oversight. They should be able to work effectively with adjacent disciplines, including combustion, while applying sound engineering judgment to problems involving thermodynamics, operability, and system behavior. This is a hands‑on analytical role for someone who enjoys moving quickly, solving real problems, and helping translate advanced concepts into viable propulsion solutions. What You’ll Do... Develop, adapt, and apply engine cycle and system performance models to evaluate advanced propulsion concepts and architecture trade space Use Python‑based tools and available cycle models to rapidly explore design options, including high‑Mach operating space and evolving system requirements Perform 1D performance calculations and support fluid system network modeling to assess system behavior, operability, and integration risks Analyze test data to evaluate engine and subsystem performance, identify issues, and inform design direction Support planning for component and system testing by helping define performance objectives, required data, instrumentation needs, and analysis approaches Work closely with mechanical design, combustion, and other engineering disciplines to evaluate system interactions and support balanced design decisions Contribute to early‑stage concept development by translating ambiguous technical questions into structured analyses and actionable recommendations Communicate technical findings, risks, assumptions, and tradeoffs clearly to cross‑functional stakeholders Document methods, models, analyses, and lessons learned in a way that supports broader engineering understanding and reuse. You have... 8+ years of a strong background in propulsion or gas turbine performance analysis Experience with thermodynamic cycle analysis, 1D calculations, and architecture trade studies Strong Python capability, including the ability to modify and use analytical models efficiently Experience analyzing test data and using results to guide technical decisions Ability to perform or support 1D network modeling of fluid systems Strong understanding of thermodynamics, engine system behavior, and performance interactions across subsystems Comfort working with combustion‑related concepts and cross‑functional teams Ability to work effectively in loosely defined, fast‑moving development environments Strong problem‑solving skills, sound technical judgment, and the ability to move work forward independently Clear written and verbal communication skills The ability to obtain and maintain a U.S. government issues security clearance is required. U.S. Citizenship is required, as only U.S. Citizens are eligible for a security clearance Nice to have... Experience with NPSS or similar cycle modeling tools Experience supporting propulsion development programs in early‑stage or advanced development environments Familiarity with operability, transient behavior, and system‑level performance considerations Experience working with experimental data, test planning, or performance validation activities Exposure to advanced propulsion concepts, novel architectures, or rapid development programs Experience with additive manufacturing environments or hardware development teams Experience in high Mach engine development Working Style and Mindset This role is well suited for someone who: Is first and foremost a doer Thrives in ambiguity and can make progress without excessive structure Can identify the real problem, not just the stated one Moves comfortably between analysis, trade studies, and practical engineering support Speaks up with ideas and objections when needed Works across a broad range of technical problems with speed and sound judgment If this sounds like you, please submit an application with your resume. This could be the opportunity you are looking for to expand your skills, contribute to a winning team, and work with talented people who love what they do and take pride in our mission.
