Description

What is JetZero?

Today’s aircraft contribute around 4% 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 developing a blended-wing body (BWB) aircraft. It uses up to 50% less fuel and will be built to accommodate zero-emission hydrogen propulsion. JetZero is the inevitable solution to sustainable air travel.

The JetZero 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 flight that' is better for both passengers and airlines around the world.

What You'll Do:

Develop, maintain, and validate aircraft and propulsion performance models supporting design, simulation, and flight test.
Own the engine performance model, including thrust, fuel flow, efficiency, bleed/power extraction, atmospheric effects, installation effects, and engine operating limits throughout the flight envelope.
Develop methods for in-flight thrust determination, using available engine parameters, aircraft state data, aerodynamic models, and flight-test measurements.
Perform engine model calibration and correlation against OEM performance data, ground-test data, and flight-test results.
Analyze propulsion and aircraft flight-test data to determine installed thrust, drag, excess thrust/power, specific fuel consumption, and overall aircraft performance.
As part of Flight Sciences, work closely with Propulsion, 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 for flight-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 in gas turbine engine performance and aircraft propulsion integration.
Demonstrated experience developing or using engine cycle/performance models and interpreting engine deck or OEM propulsion data.
Experience with in-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 correlating ground-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 conducting in-flight thrust determination on transport-category aircraft or flight-test programs.
Experience with engine performance tools such as NPSS, 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 with thrust 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 of measurement 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, including blended 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.

About this role

JetZero is building blended-wing body aircraft designed to cut fuel consumption by half and eventually run on zero-emission hydrogen. This Aircraft Performance Engineer role sits at the center of validating that vision—you'd own the engine performance models that drive design decisions and flight testing, working to prove the aircraft delivers on its efficiency promises.

The work spans the full lifecycle of performance validation: developing and maintaining propulsion and aircraft models, correlating them against real engine data and flight-test results, and analyzing actual performance during testing to extract installed thrust, drag, fuel burn, and other critical metrics. You'd collaborate across Propulsion, Aerodynamics, Flight Test, and Systems teams to establish consistent methodologies and develop the tools and processes needed to reduce and interpret flight-test data. This requires deep expertise in turbofan engine performance, aircraft propulsion integration, and the ability to move fluidly between engine cycle modeling, aerodynamic effects, and flight-test data analysis.

The ideal candidate holds an advanced degree in aerospace or mechanical engineering and brings substantial hands-on experience with engine performance models, in-flight thrust determination, and flight-test programs. You'll need strong proficiency in MATLAB and Python, familiarity with engine modeling tools like NPSS or GasTurb, and the analytical rigor to solve problems that cross traditional discipline boundaries. Experience with unconventional aircraft configurations and Part 25 certification is a plus. The role is full-time and in-office in Long Beach, Nova Scotia, with a salary range of $150,000–$180,000 plus equity, benefits including generous PTO and health coverage.
