Machine Learning Engineer – Cost Index Optimization

Machine Learning Engineer – Cost Index Optimization
Engineering | Odense, Denmark | Full-Time

Jeppesen ForeFlight builds software that airlines and pilots around the world rely on every day. From our Odense office, you'll join an international engineering organization where your work has a direct, measurable impact on airline fuel efficiency and emissions.

Train models that save fuel on every flight

We're hiring a Machine Learning Engineer for a new team building our next-generation Cost Index Optimization (CIO) product. You'll design and train the neural network models that produce tail-specific performance profiles from recorded flight data, and build the training and validation pipeline that keeps them accurate as fleets and data grow.

What you'll do

• Design neural network architectures for tail-specific performance modeling
• Build the training pipeline — data preparation, feature engineering, hyperparameter optimization, retraining
• Define and automate validation against real-world flight data and accuracy targets
• Work with aircraft performance specialists to blend physics-based and learned models, keeping outputs physics-bounded
• Package trained models into compact, fast artifacts that run offline on EFB devices in the flight deck
• Take models to production, with monitoring for drift and data quality

What we're looking for

• Strong applied ML experience — you've trained, validated, and shipped models to production, not just prototyped them
• Solid Python and ML tooling (PyTorch/TensorFlow, experiment tracking, model serving)
• Experience with time-series or sensor data, and comfort with noisy real-world datasets
• Enough physics intuition to sanity-check model outputs against how aircraft actually behave
• Interest in aviation is a plus; domain expertise is not required

Why Join Jeppesen ForeFlight?

We believe a rewarding career is built on meaningful challenges, a supportive environment, and great colleagues. At Jeppesen ForeFlight, we empower our employees to make a direct impact on our products and services while supporting their overall wellbeing.

Our benefits package includes comprehensive health insurance, a pension plan, generous paid vacation plus additional time off during Christmas, a health and wellness allowance, an employee assistance program, two paid volunteer days annually, an employee referral program, and flight rewards and a flight stipend.
