Aircraft Performance Engineer

What isJetZero? 

Today’saircraft contribute around4% of global CO2 emissions, equivalent to the emissions of 200 million cars. This is only going to increase: Air travel is forecasted to double by 2050, while meaningful efficiency gains using current airplanes have hit a wall. 

JetZero is developingablended-wingbody (BWB)aircraft. It usesup to50% less fuel andwill bebuilt toaccommodate zero-emission hydrogen propulsion.JetZero is the inevitable solution to sustainable air travel. 

TheJetZero Team 

We are experienced aerospace professionals and engineers, excited about the future. That future will only be possible if we share our vision and what it means to people’s lives: carbon-free flightthat' is better for both passengers andairlines around the world. 

What You'll Do:

• Develop, maintain, and validate aircraft and propulsion performance models supporting design, simulation, and flight test.
• Own theengine performance model, including thrust, fuel flow, efficiency, bleed/power extraction, atmospheric effects, installation effects, and engine operating limits throughout the flight envelope.
• Develop methods forin-flight thrust determination, using available engine parameters, aircraft state data, aerodynamic models, and flight-test measurements.
• Performengine model calibration and correlation against OEM performance data, ground-test data, and flight-test results.
• Analyze propulsion and aircraft flight-test data to determineinstalled thrust, drag, excess thrust/power, specific fuel consumption, and overall aircraft performance.
• As part of Flight Sciences, work closely withPropulsion, Aerodynamics, Flight Test, Systems, and Performance teams to establish consistent thrust and drag accounting methodologies.
• Conduct aircraft performance analyses including takeoff, climb, cruise, descent, landing, range, payload, fuel burn, and reserves.
• Develop tools and processes forflight-test performance reduction, including atmospheric normalization, data filtering, uncertainty assessment, and model correlation.
• Support the definition of flight-test procedures and instrumentation requirements needed to validate engine and aircraft performance.

What You Bring:

• Bachelor’s, Master’s, or PhD in Aerospace Engineering, Mechanical Engineering, or a related field.
• Strong experience ingas turbine engine performance and aircraft propulsion integration.
• Demonstrated experience developing or usingengine cycle/performance models and interpreting engine deck or OEM propulsion data.
• Experience within-flight thrust determination or flight-test propulsion performance analysis.
• Strong understanding of turbofan engine performance, including gross thrust, ram drag, net thrust, corrected parameters, fuel flow, atmospheric corrections, and installation effects.
• Strong understanding of aircraft performance, aerodynamics, propulsion-airframe integration, and aircraft energy methods.
• Experience analyzing and correlatingground-test, engine-test, simulation, and flight-test data.
• Proficiency with MATLAB and  Python and experience developing engineering analysis tools and automated data-reduction methods.
• Familiarity with aircraft data acquisition, instrumentation, telemetry, and flight-test data processing.
• Strong analytical skills and demonstrated ability to solve problems that cross traditional aerodynamic, propulsion, and flight-test boundaries.
• Excellent technical communication and documentation skills.

Preferred Skills:

• Experience conductingin-flight thrust determination on transport-category aircraft or flight-test programs.
• Experience with engine performance tools such asNPSS, GasTurb, OEM engine decks, or equivalent proprietary engine-modeling environments.
• Experience correlating engine deck predictions against measured engine parameters such as N1/N2, EGT/TGT, fuel flow, pressure, temperature, and aircraft flight conditions.
• Familiarity withthrust bookkeeping and drag accounting, including separation of installed propulsion effects from aerodynamic drag.
• Experience with flight-test techniques for determining aircraft drag, thrust, climb performance, and cruise performance.
• Understanding ofmeasurement uncertainty, parameter identification, sensitivity analysis, and statistical/model-correlation methods applied to flight-test data.
• Experience with Part 25 aircraft performance certification and certification flight testing.
• Experience with unconventional configurations, includingblended wing body aircraft and highly integrated propulsion installations.
• Familiarity with aircraft mission/performance simulation and multidisciplinary performance optimization.
• Ability to use AI to efficiently develop tools and help in the documentation.

The Interview Process  

We want our interview process to be a true reflection of our culture: transparent and collaborative. Throughout the interview process, your recruiter will guide you through the next steps and ensure you feel prepared every step of the way.  

• Our First Chat: During this first conversation, you’ll meet with a recruiter or hiring team member to chat through your background, what you could bring to our team, what you are looking for in your next role, and who we are.  
• The Hiring Manager Interview:You will meet with your potential future boss to really dive into the role, the team, expectations, and what success means at JetZero. This is your chance to really nerd out with someone in your field.  
• The Panel: Learn more about the team, responsibilities, and workflows. You should be prepared to speak about past projects, how you collaborate and communicate with others, and how you live our values. Depending on the team and role you are interviewing for, you may meet with several teammates as well as cross-functional partners.  
• The Executive Review: A chance to meet an executive and view JetZero from a different lens. Be prepared to ask well-thought-out questions about the company, culture, and more. 

Depending on the position you are interviewing for, there may also be a Take Home Exercise as part of the interview proccess. Our assessments seek to test the hard skills required to do the job. Your recruiter will inform you of which assessment you will be assigned and ensure you are fully prepared for your big day.
